海外TECH	DEV Community	Best practices for error catching and handling	https://dev.to/sargalias/best-practices-for-error-catching-and-handling-4e3m	Best practices for error catching and handlingCatching and handling errors is an important part of error handling Here are some best practices for it Generally it s good to be very thorough with your error checkingdo your error checking firsthandle errors at the earliest appropriate place for exceptions put the minimum code you can in your try blocksrestore state and resources so the program can keep executing correctlyHere are the best practices in more detail Note For this article error is defined in Terminology Errors and non errors It means anything you might throw an exception or return an error value for It doesn t just mean an unrecoverable error Be very thorough with your error checkingUnfortunately programmers aren t perfect We create bugs and make mistakes In fact we do that quite often That s why we have so many error correction tools to help us So in general you should go by the assumption that everything in your program that can fail will fail Other things that you didn t think of will also fail To minimise the issue you should be very thorough with your error checking Always catch all possible exceptions and check all error values Then handle them appropriately Check for errors firstThis one is a stylistic convention In your code it s good to do your error checking before anything else Leave the normal program execution for after For example in methods that throw exceptions try to check for errors and throw the exception as early as possible Here s a code example class Example public void Foo string a if a Length throw new InvalidArgumentException Parameter a must not be the empty string normal program execution Method Foo starts by doing its error checking The normal code execution comes afterwards Avoid doing something like this class Example public void Foo string a do some normal program execution that doesn t need parameter a check parameter a right before you need it if a Length throw new InvalidArgumentException Parameter a must not be the empty string more normal program execution In this code Foo executes some code Then it does some error checking for parameter a The same principle applies to checking error values Try to check for errors before you continue your normal program execution Here is a code example function foo const result bar if result error handle error else normal code execution The code above first checks for errors Then it continues normal program execution This organises your code into recognisable blocks Errors first normal code after It makes your code easier to scan through and easier to understand It also helps with debugging When an error is thrown less normal code will have ran This reduces the amount of code you ll have to check through when debugging Handle errors at the first appropriate placeSometimes you can t handle errors immediately You might need to propagate them to higher level code To showcase this consider this example You have a function that searches the file system for a file If it finds it it reads its contents Otherwise it throws an exception How should the code handle this exception Should it crash the program create a new file search for a backup file in a different location notify the user that the file couldn t be found and ask them to try a different file The file system code doesn t know Different programs will want different behaviour if the file isn t found This means that the file system code can t have hardcoded behaviour to handle the exception Instead the exception should be handled at a more appropriate place The place that can decide what to do about it Often that means some code higher up in the call stack So the exception or error value needs to propagate up to that place For exceptions that means that you should let the exception bubble up Then have a try catch block at the place where you ll handle it For error values you ll have to manually return them until they reach the correct place in the call stack Having said that you should handle errors at the first appropriate place Don t propagate them higher than necessary The earlier you handle errors the closer they ll be to the code that raised them This makes the execution flow of the code easier to track and understand Here s a code example where we search the database for a record server jsimport getSpriteById from myDatabase js app get spriteId async req res gt const spriteId req spriteId try await getSpriteById spriteId catch error exception from database is handled here In this case it responds with a res sendStatus return res send Sprite found app post foo async req res gt const spriteId req body spriteId try await getSpriteById spriteId catch error exception from database is handled here In this case it redirects to another page for the user to fill in correct information res redirect form return res send Data accepted myDatabase jsconst db await connectToDatabase connectionString const getSpriteById async spriteId gt throws exception if it doesn t find the record const sprite await db findById spriteId return sprite export getSpriteById By the way the code is pseudocode don t expect it to work if you actually run it However it showcases the point In the example the function getSpriteById searches the database If it doesn t find the record it s looking for it throws an exception It doesn t handle the error itself Instead the handlers in server js decide how to handle the error Both handlers have try catch blocks which handle the exception differently based on what they need For exceptions Be careful of how much code you put in your try blocksIt s considered best practice to put as little code as possible in each try catch block This means that you may need multiple try catch blocks instead of just one The benefits of this are that it s easy to see which code raises which exceptions and which code doesn t raise exceptions it separates concerns more clearly Each try catch block is a separate piece of functionality This makes it easier to refactor it into a separate function it prevents the accidental swallowing of exceptions This happens if you put some code in try without thinking That code might throw an exception that you weren t prepared to handle However it will be caught in catch and potentially handled incorrectly Then the program will continue executing potentially producing the wrong result It s also a solution for when certain lines of code can throw the same type of exception but each case needs to be handled differently On the flip side having small try catch blocks can make the code more verbose In the end you need to be pragmatic Keep the benefits and downsides in mind Then make your decision Usually correctness and clarity are more important even if they re more verbose However it s okay to make the code more concise sometimes especially if you don t think correctness and clarity are too affected For example this code could be separated further but is still pretty good BufferedReader bufferedReader null try bufferedReader new BufferedReader new FileReader path String line bufferedReader readLine while line null doSomething line line bufferedReader readLine catch FileNotFoundException IOException e e printStackTrace finally try bufferedReader close catch IOException e e printStackTrace Here is the same example separated more BufferedReader bufferedReader null try bufferedReader new BufferedReader new FileReader path try String line bufferedReader readLine while line null we re leaving this line here for simplicity but depending on how it works it might need its own try block doSomething line line bufferedReader readLine catch IOException e e printStackTrace catch FileNotFoundException e e printStackTrace finally try bufferedReader close catch IOException e e printStackTrace The second version would be necessary if each catch block needed to have different code Otherwise you can choose either version The best solution is probably to use a with using try with resources statement or the equivalent for your programming language It automatically closes the bufferedReader at the end The code above is just to showcase the point Restore state and resourcesIf you successfully handle an error then the program should be able to continue executing correctly It should continue almost as though the error never happened This means that you need to restore state to something correctclose any side effects that were started by erroring code Restore stateAfter recovering from an error your program needs to have the correct state If it doesn t then you haven t really recovered This means that you might need to fix or restore your program s state in your error handling code Here s an example Consider that you have a Boolean variable The Boolean variable should start as false However while some code is running you set it to true At the end you set it to false again But if the program errors at some point the variable won t be reset This will leave your program in a bad state even if the error is handled Here s an example of some dangerous code which will have invalid state if an error occurs let isBusy false async function handleUserEvent event if isBusy isBusy true do something asynchronous which may throw an exception for example await doSomething isBusy false If handleUserEvent errors the value of isBusy will remain false forever handleUserEvent won t be able to run properly again For that reason you need to manually reset the state if an error occurs Here s a code example let isBusy false async function handleUserEvent event if isBusy isBusy true try do something asynchronous which may throw an exception for example await doSomething finally isBusy false fix the state exception is sent higher up because there s no catch block equivalent exampleasync function handleUserEvent event if isBusy isBusy true try do something asynchronous which may throw an exception for example await doSomething catch error isBusy false fix the state throw error isBusy false In this example if an error occurs in handleUserEvent there s no problem The state is restored and handleUserEvent will execute correctly afterwards The same principle applies across all of your code in the call stack Imagine that an error occurs in function bar But you handle the error in function foo which is function calls earlier in the call stack For the program to be in a valid state you need to make sure that you ve fixed all of the state from bar to foo Basically it means that you may need many intermediate try catch blocks in different functions in the call stack You fix the state in each one That way if the error is handled higher up the state of all the intermediate code has been fixed They can run again as though nothing went wrong For example handleUserEventimport foo from foo js this is the top level functionasync function handleUserEvent try await foo catch error handle the error at the top level record error display message to user that action didn t work foo jsimport bar from bar js let isBusy false async function foo if isBusy return isBusy true try await bar finally isBusy false restore this module s state exception is sent further up because there is no catch block export default foo bar jslet isBusy false async function bar if isBusy return try do something asynchronous which may throw an exception for example await doSomething finally isBusy false restore this module s state exception is sent further up because there is no catch block export default bar Yes I know the code in the examples is very contrived but hopefully it illustrates the point Close side effectsSome side effects come in pairs For example if you open a file you should also close it It can be unsafe to leave it open So make sure that resources like that are properly released If you use exceptions use with blocks These automatically close resources if an error occurs Some examples are with in Python try with resources in Java or using in C otherwise use finally blocks or their equivalent in different programming languages If you re using error values place the closing code somewhere appropriate It should run both in the error case and the non error case Here s an example with finally pseudocodelet file try file openFile foo txt open the resource writeToFile file bar catch error code to handle exceptions finally close file close the resource Here s an example with error values pseudocodeconst fileError file openFile foo txt if fileError handle error close file return const writeError writeToFile file value bar if writeError handle error close file Final notesSo that s it for this article I hope that you found it useful As always if any points were missed or if you disagree with anything or have any comments or feedback then please leave a comment

海外TECH	DEV Community	Como se proteger na internet: Golpe do WhatsApp	https://dev.to/viniciusscs/como-se-proteger-na-internet-golpe-do-whatsapp-19ap	Como se proteger na internet Golpe do WhatsAppHoje sabemos que existem inúmeras formas de ataques clones de números de telefones golpes em WhatsApp Fake News e sempre ficamos com aquela pergunta E AGORA QUEM PODERÁNOS AJUDAR O problema éque hoje no Brasil não se tem alguém que faça isso que de fato resolva esse problema e a justificativa ésimples veja bem para que um golpe pelo WhatsApp sim aquele que o meliante usa um número X se passando por uma pessoa que vocêconhece seja seu pai sua mãe irmãos ou filhos enfim esse golpe émuito comum hoje em dia porém muito caro Sim meus amigos écaro pro estado abrir uma investigação para descobrir que o meliante jáse encontra preso Ah Vinícius mas o cara tásolto me aplicou um golpe de estelionato Nesse caso por enquanto o que podemos fazer écumprir três etapas lembrando que independente se o golpista esta solto ou preso éimportante cumprir essas etapas Etapa Contatar o BancoEtapa Fazer um Boletim de OcorrênciaEtapa Mover uma ação jurídica Contatar o Banco A primeira coisa étentar estabelecer contato com o banco que recebeu aquela transferência bancária ou atémesmo o banco que foi utilizado para realizar o pagamento daquele boleto que eventualmente foi falsificado Fazer um Boletim de Ocorrência Em segundo lugar devemos fazer um registro de ocorrência na delegacia de policia mais próxima Primeiro porque vocêfoi vítima de uma fraude e essa fraude precisa ser investigada atépara que novas pessoas não sejam vitimas de fraudes semelhantes Segundo porque se na fraude você por ventura informou seu CPF ou qualquer outro dado que posso ser usado para te denegrir seja usando seu nome que pode ser utilizado em novos golpes ou para o meliante usar seu CPF em cadastros de lojas Mover uma ação jurídica Em terceiro lugar dependendo da circunstância em que o golpe foi aplicado e o valor subtraído vocêpode tentar mover uma ação para tentar reaver o prejuízo que sofrido em função desse golpe Mas então qual o objetivo desse artigo Se não tem muito o que ser feito Se o golpista muitas vezes fica livre e continua aplicando golpes Vem comigo que vou te explicar tudo Então para que serve esse POST Então esse POST serve para seus irmãos filhos amigos que trabalham em outra área e que não possuem o mesmo conhecimento que eu e você que jáestamos calejados de tecnologia e sabemos o que deve ser feito Acredito que possamos ajudar pessoas de outras áreas E pensando nisso nessas pessoas vou tentar passar para vocês um pouco do que aprendi são passos simples que podem ajudar pessoas que não possuem o mesmo conhecimento a não cair em golpes como esses do WhatsApp Se atentem na informaçãoMuitas vezes nos deparamos com a seguinte mensagem Bom dia mãe salva meu contato novo Meu aparelho deu problema e precisei deixar na assistência Toda vez que seu telefone estraga vocêleva com vocêo chip ninguém repito NINGUÉM fica com seu chip em assistência técnica então se o número do seu familiar é e vocêreceber essa mensagem com essa informação de um número diferente pode acender a luz de alerta Esse éum caso comum que simplesmente ao receber esse tipo de mensagem podemos com calma entrar em contato por mensagem ou ligação para o número ORIGINAL no caso o número do exemplo foi e saber se a informação bate e pasmem das vezes as informações vão ser distorcidas Bora pro segundo ponto Pergunte algo inventadoIsso jávi muito as vezes o primeiro passo fica meio vago talvez porque seu familiar ou amigo não atendeu para poder confirmar as informações e o meliante jáestáimportunando não para de mandar mensagem começa a tentar tirar alguma informação de você e a gente precisa reagir fazer algo para saber se estamos ou não falando com a pessoa certa Nesse ponto podemos simplesmente fazer uma pergunta veja o exemplo Meliante Bom dia mãe salva meu contato novo Meu aparelho deu problema e precisei deixar na assistência Mãe Esperta Oh minha filha tudo bem Seu celular estragou na queda quando saía aqui de casa Aíuma observação importante da Mãe Esperta ela usou uma mentira uma informação completamente inventada essa queda nunca aconteceu vocêsabe disso mas o Meliante não e ele vai responder Sim nessa queda meu celular estragou Esse ponto éimportante porque vocênota com muita facilidade que tem algo errado éa mesma coisa de vocêperguntar Como estásua tia Fulana usando um nome que não existe na família Lembrem se são pontos importantes que devem ser pensados com calma Mas Vinícius vocêestáusando exemplos fácies demais e se o meliante for audacioso e falar algo comoMeliante Bom dia mãe me ajuda sofri um acidente fiquei sem bateria e estou usando o celular de um amigo Pessoal jásofri em torno de acidentes sendo gravíssimos NUNCA mandei uma mensagem para meus pais sempre ligação Então por lógica e conversando com pessoas que sofreram acidentes e o mais provável mais uma vez NINGUÉM envia mensagem falando de acidente grave ainda mais usando o número de outra pessoa seja amigo ou não O instinto do ser humano éresolver o problema de forma rápida então a forma mais rápida seria uma ligação Isso nos remete ao passo se atentem a informação passada CONCLUSÃOSempre o Meliante vai estar em desvantagem se vocêseguir com esses passos e ficar calmo porque da mesma forma que vocênão sabe quem éque estápor trás do WhatsApp o meliante também não sabe quem évocê E se a pessoa que estiver sendo vítima ficar calma e seguir os passos consegue muito facilmente saber se éum golpe ou não Galera esse post jáficou muito grande quero agradecer a todos que tiraram um tempo para ler atéo final e principalmente aqueles que leram e compartilharam Então se cuidem e se tudo der certo vem parte vou falar ajudar vocês nessa BlackFriday vulgo conhecido como BlackFraude Que a força esteja com vocês	2021-11-19 17:25:54
海外TECH	DEV Community	How I implemented sticky columns in tables using directives - Angular!	https://dev.to/angular/how-i-implemented-sticky-columns-in-tables-using-directives-angular-nkb	How I implemented sticky columns in tables using directives Angular How to create sticky columns in Angular using directives Implementing tables with sticky columns can be tricky especially when you have to make multiple columns sticky Using directives we can easily implement sticky columns I can t emphasize more the power of directives in Angular I ve written a couple of articles showcasing how one can actually use it to implement really cool stuff You can check some use cases for directives here Angular Directive Showcase Tables with sticky columnsWe make use of the position sticky CSS property to make an element sticky Read more about sticky positioning at MDN sticky position sticky left For the sticky position to work properly at least one of top right bottom or left should be specified The problemMaking the first column in a table sticky is super simple you basically add the sticky class to the column When two columns need to stick to the left we can t just add the sticky class to both of the columns This is how it looks if you did so Here you can see the Manager column overlapping with the Company column This is because we gave both the columns left To make it work as expected the styles should be like this company position sticky left px manager position sticky left px lt width of the company column What we did here is we added the offset of the Manager column as the left property value Sticky CalculationsFor calculating the left value we need to find the x value of the column If we look at the first column Company and get its offset from the left side We expect the x value to be but we get here This is because the x value is calculated from the left side of the window to the column For getting the left threshold of the column with respect to the table we need to find the x value of the table Once we get the table s offset we can subtract it from the offset of the column Example of the calculation Position of Table lt x Position of Company lt x with respect to table Position of Manager lt x with respect to table Sticky DirectiveWe are going to create a directive to do just that The directive can then be placed on the columns which need to be sticky If you are thinking about why a directive for this particular use case the calculation of the sticky thresholds can be done easily Creating a directive makes it easy to re use the functionality for different elements import CommonModule from angular common import AfterViewInit Directive ElementRef NgModule Optional from angular core Directive selector stickyTable export class StickyTableDirective constructor private el ElementRef get x return this el nativeElement as HTMLElement getBoundingClientRect x Directive selector sticky export class StickyDirective implements AfterViewInit constructor private el ElementRef Optional private table StickyTableDirective ngAfterViewInit const el this el nativeElement as HTMLElement const x el getBoundingClientRect el style position sticky el style left this table x this table x px px NgModule declarations StickyDirective StickyTableDirective imports CommonModule exports StickyDirective StickyTableDirective export class StickyDirectiveModule If you look at the code above we have two directives StickyDirectiveStickyTableDirectiveThe second directive is really interesting here Why do we need a second directive We have a separate directive that can be placed on the table to get the offset of the table The directive can then be injected inside the main StickyDirective constructor private el ElementRef Optional private table StickyTableDirective We mark the StickyTableDirective as Optional so that we can add the StickyDirective directive on other elements and it can automatically be sticky with the default value Ref optionalHere is how we use it in HTML lt table stickyTable gt lt tr gt lt th sticky gt Company lt th gt lt th sticky gt Manager lt th gt lt th gt Employees lt th gt lt th gt Contractors lt th gt lt th gt Jobs lt th gt lt th gt

of improvements can be made to this directive to make it more re usable like Add support for other directions Generalize the StickyTableDirective to be able to use it on other elements as well For the

海外TECH	Engadget	Why Apple changed its mind on Right to Repair	https://www.engadget.com/apple-user-iphone-repair-policy-change-173047862.html?src=rss	Why Apple changed its mind on Right to RepairApple does not have a good track record in terms of letting customers repair their hardware The last decade plus has seen Apple s computers become essentially impossible for users to service or upgrade and the iPhone has always been a locked box Adventurous owners might follow guides from iFixit to try and do repairs themselves but it s a dangerous proposition Remember it was just earlier this year when we discovered that replacing the display on an iPhone would disable Face ID something Apple eventually made an about face on So Apple s announcement earlier this week that it would start selling parts and tools directly to consumers and offer repair guides was a huge surprise and a move immediately hailed as a victory for right to repair activists “One of the most visible opponents to repair access is reversing course said Nathan Proctor a senior Right to Repair campaign director at Public Interest Research Groups PIRG “Apple s move shows that what repair advocates have been asking for was always possible iFixit was similarly pleased saying that the move is “exactly the right thing for Apple to be doing Both groups caveated their statements by noting a few catches PIRG says that Apple s plans weren t as comprehensive as the right to repair legislation being discussed in more than two dozen states while iFixit wants to “analyze the legal terms and test the program before it can say just how much credit Apple deserves But regardless it s still a major about face So what led Apple to this move Proctor told Engadget in an email exchange that he thinks “combined pressure from consumers regulators and shareholders has shifted Apple s thinking But he was also quick to point out that there was pressure coming from inside Apple itself “We saw from some leaked emails from that many inside Apple never wanted to be hostile to repair in the ways that Apple has been at times he said You probably saw that Apple co founder Steve Wozniak called out the practices but leaked emails show internal concern they were doing the wrong thing Apple has made some other movies recently that show that potential government scrutiny and oversight could be driving change at the company In Apple finally let users set different browser and email apps as default on the iPhone and iPad and Siri has gotten smarter about learning your preferences for different music apps when you ask it to play tunes While it s likely that Apple is thinking about government pressure this change might also simply be part of the company listening to its users and correcting some mistakes it made over the last five years or so Take the new MacBook Pro perhaps the biggest “mea culpa Apple has ever offered the company reversed its trend of pursuing thin and light design at all costs and instead actually made the both the and inch MacBook Pros thicker and heavier than their predecessors The company also added back ports it had previously removed killed the unpopular Touch Bar and generally made a laptop that made it seem like they were listening to consumer feedback The same could be said for its new home repair program Regis Duvignau ReutersApple s move this week can also be seen as an extension of a program the company launched last year when it started providing parts and training to third party repair shops that met Apple s qualifications Obviously this isn t the same as making it easy for anyone to do repairs but opening up access means the repair landscape for Apple products has changed significantly in the last few years However big of a change this new plan is though Proctor and PIRG see this as a first step something Apple will need to keep up and expand to really meet what right to repair activists think consumers deserve “I think Right to Repair knows what it wants and it will be really hard to convince us to settle for anything less than an open market for repair Proctor said “If they had done this step years ago maybe we would have to settle but we have the momentum and we are going to empower repair as much as we can I think most legislators agree this is just one company and a limited program The floor got raised but we aren t near the ceiling yet iFixit has a similar view on the situation “ Apple pioneered glued in batteries and proprietary screws and now they are taking the first steps on a path back to long lasting repairable products iFixit believes that a sustainable repairable world of technology is possible and hope that Apple follows up on this commitment to improve their repairability As for what s to come it sounds like Apple is committed to making this just a first step The company said that repair options would initially focus on commonly repaired modules in the iPhone and like the screen battery and cameras but it says that more options will come in the following year We don t know if Apple will ever give right to repair activists everything they want It seems unlikely that Apple will make an iPhone where you can just pop it open and drop a new battery in like the phones of old Apple can often be a bellwether for the rest of the industry ーjust look how quickly other phone makers dropped their headphone jacks So it s possible we ll see some other big consumer electronics companies make similar moves “I think other companies will follow Proctor said He also noted that Google had just released software that lets a replacement display on the Pixel be properly calibrated to work with the in screen fingerprint sensor We see a lot of changes in the works and we are hopeful we can set a new baseline for access to repair If that happens we ll likely remember Apple s about face as a major catalyst for these changes ーassuming the company follows through with its new stance and makes it easier for owners to repair a wider variety of its products	2021-11-19 17:30:47

GCP	Cloud Blog	Edge computing—a paradigm shift that goes beyond hybrid cloud	https://cloud.google.com/blog/topics/hybrid-cloud/edge-plus-cloud-enables-new-kinds-of-enterprise-apps/	Edge computingーa paradigm shift that goes beyond hybrid cloudWhether with the cloud or within their own data centers enterprises have undergone a period of remarkable consolidation and centralization of their compute resources But with the rise of ever more powerful mobile devices and increasingly capable cellular networks application architects are starting to think beyond the confines of the data center and looking out to the edge  What exactly do we mean by edge Think of the edge as distributed compute happening on a wide variety of non traditional devices ーmobile phones of course but also equipment sensors in factories industrial equipment or even temperature and reaction monitoring in a remote lab Edge devices are also connected devices and can communicate back to the mothership over wireless or cellular networks  Equipped with increasingly powerful processors these edge devices are being called upon to perform tasks that have thus far been outside the scope of traditional IT For enterprises this could mean pre processing incoming telemetry in a vehicle collecting video in kiosks at a mall gathering quality control data with cameras in a warehouse or delivering interactive media to retail stores Enterprises are also relying on edge to ingest data from outposts or devices that have even more intermittent connectivity e g oil rigs or farm equipment filtering that data to improve quality reducing it to right size information load and processing it in the cloud New data and models are then pushed back to the edge in addition we can also push configuration software and media updates and decentralize processing workload Edge isn t all about enabling new use cases it s also about right sizing environments and improving resource utilization For example adopting an edge model can also relieve load on existing data centers  But while edge computing is full of promise for enterprises there are many pieces that are still works in progress Further developing edge workloads is very different from developing traditional applications which enjoy the benefits of persistent data connections and run on well resourced hardware platforms As such cloud architects are still in the early days of figuring out how to use and implement edge for their organizations  Fortunately there are tools you can use to help ease the transition to edge computing ーand that likely fit into your organization s existing computing systems Kubernetes of course but also higher level management tools like Anthos which provides a consistent control plane across cloud private data center and edge locations Other parts of the Anthos family Anthos Config Management and Anthos Service Mesh ーgo one step further and provide consistent centralized management to your edge and cloud deployments And there s more to come For the remainder of this blog post we ll dive deeper into the past and current state of edge computing and the benefits that architects and developers can expect to see from edge computing In a next post we ll take a deeper look at some of the challenges that designing for edge introduces and some of the advantages the average enterprise has in adopting the edge model Finally we ll look at the Google Cloud tools that are available today to help you build out your edge environment and look at some early customer examples that highlight what s possible today ーand that will spark your imagination for what to do tomorrow  The evolution of edge computing The edge is not a new concept In fact it s been around for the last two decades spanning many use cases that are prevalent today One of the first applications for edge was to use content delivery networks CDN to cache and serve daily static website pages near clients for example web servers in California data centers serving financial data to European customers  As connectivity has improved and software evolved the edge has evolved too and the focus has shifted towards using edge to distribute services First simple services expanded from static HTML to javascript libraries or image repositories Common functions like image transformation credit and address validation support services followed Soon organizations were deploying more complex cloudlet and clustered microservices installations as well as distributed and replicated datasets The term “endpoint became ubiquitous and APIs profilerated  In parallel there s been an explosion of creativity in hardware microcontrollers and dedicated edge devices Fit for purpose products were deployed globally Services like Google Cloud IoT Core extended our ability to manage and securely connect these dispersed devices allowing platform managers to register tools and leverage managed services like Pub Sub and Dataflow for data ingestion And with Kubernetes large remote clusters ーmini private clouds in and of themselves ーoperate as self healing autoscaling services across the broader internet opening the door to new models for applications and architectural patterns In short both distributed asynchronous systems and economies have blossomed What does this mean for enterprises For the purposes of this series edge means you can now go beyond the corporate network beyond cloud VPCs and beyond hybrid The modern edge is not sitting at a major remote data center nor is it a CDN cloud provider or in a corporate data center rack ーit s just as likely to look like of these attached to a thousand sensors Raspi Ks ClusterEdge in short is about having hardware and devices installed at remote locations that can process and communicate back the information they collect and generate The edge management challenge meanwhile is being able to push configuration and software model media updates to these remote locations when they are connected Enable new use casesToday we have reached a new threshold for edge computing ーone where micro data processing centers are deployed as the edge of a fractal arm as it were Together they form a broad geographically distributed always on framework for streaming collecting processing and serving asynchronous data This big loosely coupled application system lives breathes and grows Always changing always learning from the data it collects ーand always pushing out updated models when the tendrils are connected  Right now the rise of G is pushing the limits of edge even further Devices enabled with G can transmit using a mobile network ーno ISP required ーenabling connectivity anywhere within reach of a cell tower Granted these networks have lower bandwidth but they are often more than adequate for certain types of data for example fire sensors in forests bordering remote towns that emit temperature or carbon monoxide data periodically Recently Google Cloud partnered with AT amp T to enhance business use of G edge technology but there is so much more that can be done  Reduce data center investmentsIn addition to enabling the digitization of a broad range of new use cases adopting edge can also benefit your existing data center Let s face it data centers are expensive to maintain Moving some data center load to edge locations can reduce your data center infrastructure investment as well as compute time spent there Edge services tend to have much lower service level objectives SLOs than data center services driving lower levels of hardware investment Edge installations also tend to tolerate disconnectedness and thus function perfectly well with lower SLOs ーand lower costs  Let s look at an example of where edge can really reduce costs big data Back in the day we used to build monolithic serial processors ーstate machines ーthat had to keep track of where they were in processing in case of failure But time and again we ve seen that smaller more distributed processing can break down big expensive problems into smaller more cost effective chunks  Starting with the explosion of MapReduce almost years ago big data workloads were parallelized across clusters on a network and state management was simplified with intermediate output to share wait for or restart processing from checkpoints Those monolithic systems were replaced by cheaper smarter networked clusters and data repositories where parallel work could be executed and rendered into workable datasets  Flash forward to today and we are seeing those same concepts applied and distributed to edge data collection points In this evolution of big data processing we are scaling up and out to the point where observation data is so massive that it must first be prefiltered and then preprocessed down to a manageable size and still be actionable Only then should it be written back to the main data repositories for more resource intensive processing and model building In short data collection cleanup and potentially initial aggregation happens at the edge location which reduces the amount of junk data sitting in costly data stores This increases performance of the core data warehouse and reduces the size and cost of network transfers and storage  The edge is a huge opportunity for today s enterprises But designing environments that can make effective use of the edge isn t without its challenges Stick around for part two of this series where we look at some of the architectural challenges typically encountered while designing for the edge and how we begin to address them Related ArticleIntroducing Google Distributed Cloudーin your data center at the edge and in the cloudGoogle Distributed Cloud runs Anthos on dedicated hardware at the
