海外TECH	DEV Community	Serverless Design Principles	https://dev.to/transienterror/serverless-design-principles-4jl7	Serverless Design Principles IntroductionServerless is becoming more and more popular these days It has alwaysbeen an interesting space for me because I m interested in thestateless functional style of programming I started working on Lambdafunctions essentially as my first project as an SDE at Amazon back in worked with one of our purely serverless data storage services atAmazon Fashion eventually made my way to the actual Lambda backendteam and now at Microsoft I find myself working with Azure Functionsagain Obviously Lambda has not really existed for that long so Ithink I ve basically maxed out on possible number of years ofServerless experience I hope to highlight some of the more interestingdifferences between more classic design with servers and serverlessdesign MotivationsI wanted to start with why we would use Lambda Functions over classicVMs or Kubernetes clusters The original motivation for Lambda wasmostly to save costs but later on we noticed some efficiencies thatcould only be realized at Lambda scale Saving costsThere are a lot of web services out there that generally serve less than transaction per second but were still costing a lot in VM usage Theidea was that there should be an efficient way for us to schedule a lotof these web services on the same hardware so that we can save a lot ofmoney Efficiencies at scale minimizing resource contention with dataAfter running Lambda for a while Lambda realized there were ways thatwe could schedule work really efficiently Lambda has the data toanalyze different workflows to see what their bottleneck resource is and schedule them such that the functions would not have to contend forthe same resource at the same time For example it would be optimal toschedule a memory heavy workflow with a compute heavy workflow so theyare much less likely to contend for the same resources There is anexcellent talk by Marc Brooker about this you can find here It s just easierI d be remiss if I didn t include this but a lot of the time Lambdaand its ilk are just the easiest services to set up requiring littleknowledge of server infrastructure and that makes it much easier to useto a broad audience Last year I threw together a demo of a bookstoreto give a talk on design for the CS department at my alma mater and itwas just easier to use API Gateway backed by Lambda and DynamoDB so Ididn t have to really think about servers at all Key ideasThese are some key ideas that will come up repeatedly in our bestpractices I m highlighting these specifically because they differ fromtraditional serverful architecture ConcurrencyWe use the number of concurrent invocations to talk about the scale of aFunction not requests per second or capacity which is moretraditional You can calculate your concurrency by multiplying yourrequests per second by the expected latency of the request seeLittle s Law There isactually quite a lot of content in Marc s talk that I linked to earlierabout this if you want a deeper dive on why this is the case The mainreason is that concurrency is a measure that doesn t depend on hardware hence serverless right Concurrency also takes into account howefficiently you re responding to requests rather than just how manyrequests you re getting One common ticket I d see at Lambda would bea team wondering why they were being throttled when they had lowrequests per second more on this later Cold startsThe big issue with serverless that people like to talk about is higherlatency from cold starts A cold start is essentially when yourexecution environment needs to both prepare for the execution and thenactually perform the execution At Lambda we called these stages Initand Invoke It s not uncommon to see cold starts that are over seconds especially if you re not careful I ve also seen many ticketsabout this in my time at Lambda Quick detour on code data reuse I also wanted to include a quick interlude about how persistentresources get reused because I think it s practical for those new atwriting these Functions Class membersWe talked a little bit about init and invoke Intuitively you dthink well I m creating some resources let s say a DB client duringthe init phase but how does it get reused Do I instantiate a newclient per request or can we reuse resources across invokes Theanswer thankfully is that you do in fact reuse these resourcesacross invokes If you initialize your DB client outside of yourfunction definition it will be reused the next time you invoke somembers of your class probably behave as you would expect coming from amore serverful background Let me illustrate this with a quick example class Function db client None def handle invoke event context if db client is None db client DbClient return db client get some stuff On your first invoke you will instantiate a new DbClient verbatim but on subsequent requests to the same execution environment db client verbatim will continue to already be instantiated so youwill be able to get some stuff verbatim directly The more perceptive readers may notice a potential problem here Ifyou re following security best practices using ephemeral credentialsthat expire after some hours you could experience credentials issues byreusing these clients If you re using the AWS SDK this will begenerally handled for you but otherwise it s something to keep in mindas you re developing File SystemThis is a quick one If you use EFS with Lambda or by default with AzureFunctions your invokes all share the same file system This wasoriginally meant for machine learning workflows where people haverelatively large training models they want to load but has plenty ofother uses Best practicesHere are a collection of best practices that I found to be less commonlyreported but are really helpful with design Keep functions short like less than minutes If you read the Azure Functions best practices they say that you shouldkeep your functions short because they timeout This is true of course Lambda used to time out at minutes but now has extended to minutes So you might think well if I limit my function to minutes I should be pretty safe Unfortunately there is more nuance here Earlier I introduced the concept of concurrency and Little s Law centerL lambdaW latex L verbatim is the concurrency λis the effective arrival rate requests per second and W verbatim is the wait time latency For example the largest throttling point for Lambda in one of theregions is concurrent invokes If you consider a minute function seconds we can calculate the λ or requests per second at whichyou ll be throttled center λ   λ    λ    Oops just From the equation itself you can see that the higher the latency thelower the requests per second your function will be able to handle Evenusing the default numbers the λdecreases unintuitively quickly as Wincreases Generally speaking Lambda is designed to execute short functions andother tools such as AWS Batch or ECS are better suited for longerrunning jobs Cold start relatedLet s dig a little deeper on the steps to init Generally speaking no matter the serverless environment we have to do these things Acquire an execution sandbox Pull the code executable into the sandbox Start the executable runtime e g JVM or CLR Run your init code Keep functions small like under MB We ve also already talked about cold starts One of the mostunintuitively slow parts of a cold start is actually pulling yourcode binary I suggested the limit of MB or so mainly because lots ofpeople insist on using Java or C to write functions but in reality ifyou re using an interpreted runtime like python or node you can easilykeep your code under MB I mean in this case Java and C will be likex slower and that s just to download the executable Use an interpreted runtime for more predictable resultsWhile we re on the topic of runtimes try to use a fast runtime JVMand CLR have a reputation of taking a long time to initialize I wouldroutinely see such functions take upwards of seconds to initialize While JVM and CLR languages generally execute faster than node orpython if you re following the earlier advice about functionduration you are spending a much higher proportion of your time ininit causing more latency instability when you do hit a cold start Inmy experience node has been a good choice for having a more consistentexperience You can also bypass the runtime completely and pick acompiled language like Golang or Rust I ve also been on teams thatused Golang to great effect with Lambda as well Be mindful of priceIt s easy to get lost in the ease of using Functions and forget howmuch you re spending I ve accidentally spent thousands of dollars ofAmazon s money in just a few days The pricing model is a constantcost per invoke and then a rate on GBs where GB is how much memoryyou ve allocated not how much you re using and seconds of invocationrounded to the nearest millisecond This means the less you use theless you pay but also conversely the more you use the more you pay It d be good to look up how much it would cost to get a VM orKubernetes to do the same job and make sure you re willing to pay theexcess I ve found that the point where Lambda starts costing morehappens at a much lower concurrency than people generally think Ofcourse functions do more than VMs They scale automagically do OSpatching etc so it may be worth it to you but you should at leastknow how much you re paying for that Assorted Tips Lambda currently doesn t charge for inits under sLambda doesn t really like people spreading this particular tidbit butthis is relatively widely known now In order to optimize cold starttimes your init phase is generally run on a more powerful sandboxand you don t have to pay for it The caveat is that if you spendmore than seconds in the init phase the sandbox is restarted andyou will be charged for init There is a blog post that wentrelatively viral about this phenomenon Init can happen before you actually make an invoke requestThis one surprises customers from time to time but in order to optimizecold starts the platform can initialize your execution environment wellbefore you actually make an invoke Especially if you make use of thedependency injection features Reworking the previous example a littlebit to show a common way that this comes up class Function def init self logger SomeCustomLogger self db client DbClient logger logInfo db client is initialized def handle invoke event context return db client get some stuff If we log the initialization of db client verbatim you can see thatlog statement even if you did not make a request Don t use Task without returning something in Azure Functions when you can This is more off a quirk of how async await works in dotnet but plainTask verbatim functions are syntactic sugar for void verbatim But since execution metadata is saved in the Task verbatim object if you use just plain Task verbatim you return void verbatim and you lose all your execution metadata For example if you returnTask verbatim all Exceptions are suppressed because there isno way to return them to the caller For that reason I suggest at leastreturning something like Task lt bool gt verbatim which will throwExceptions as expected Actually within Lambda we had several levels of cold starts which I get into a little bit later but we re keeping it simplefor now  Shoutout to But probably you ll have issues with Rust s really large

海外TECH	DEV Community	Auto CORS Preflight Handle wih Gorilla/Mux and Go	https://dev.to/evillord666/auto-cors-preflight-handle-wih-gorillamux-and-go-855	Auto CORS Preflight Handle wih Gorilla Mux and Go IntroductionNowadays big backend solutions typically look like a set of microservices interacting with each other and with one or more frontend typically browser applications These services could be distributed across multiple virtual or physical machines and as a result every application means server that hosts application would get a different domain name ip address A frontend application typically uses Javascript or Typescript to interact with the backend but if a request goes to a different from the frontend server server a browser might assume that it poses a potential risk to security and block it To solve this issue the backend API should provide headers with a valid origin a domain name or ip where the frontend application is located Today we gonna learn how to properly setup Gorilla mux Web API to forever forget about CORS What we should provide from backendConsider the following REST resource i e user GET api user for getting all usersGET api user id for getting single user by idPOST api user for creating new userPUT api user id for update existing userDELETE api user id for delete existing userBasically we have to implement the following things Add response to OPTIONS to endpoints OPTIONS api user and OPTIONS api user id with the following headers Access Control Allow Origin domain name ip or for any origin Access Control Allow Headers here we could simply set Access Control Allow Methods we could simply list all methods but i think it is better to send OPTIONS GET POST as a value for api user and OPTIONS GET PUT DELETE for api user id Add optional origin check on server side if neccessary Today s article is about the first one you can find the second one github com gorilla handlers it It has a middleware that restricts access only to specific origins Perhaps you noticed that your backend is not always required to respond to OPTIONS request because OPTIONS request is not being sent by browsers for simple requests But in the above example we have to do this When your api is quite big you have to constantly add preflight handlers see example below and every once in a while you could forget to do that especially when you have just finished designing some complicated endpoints Using our Wissance LLC solution open source github package you can forget about adding preflight handlers because our package does this automatically Please give us a star if you find our package useful for you it s very important to us How to make all these works easilyWe implemented our own HandlerFunc that has a signature similar to mux Router HandlerFunc but with some minor differences We are passing a pointer to mux Router as a first parameter We did this because we have a requirement to work with subrouters too take a look at this unit test you can use a reference We are passing handler methods parameters as a last variardic parameter instead of calling Methods when assigning route handler we think this also makes things simpler Basically for auto preflight handling we need to create WebApiHandler instance and pass the required origin value to it as its second argument Access Control Allow Origin header supports only single value and use our HandlerFunc instead of gorilla mux see example handler NewWebApiHandler true AnyOrigin Get only method baseUrl configResource baseUrl api config handler HandleFunc handler Router configResource webApi GetConfigHandler GET full crud functionResourceRoot baseUrl api function handler HandleFunc handler Router functionResourceRoot webApi GetAllFunctions GET handler HandleFunc handler Router functionResourceRoot webApi CreateFunction POST functionResourceById baseUrl api function id handler HandleFunc handler Router functionResourceById webApi GetFunctionById GET handler HandleFunc handler Router functionResourceById webApi UpdateFunction PUT handler HandleFunc handler Router functionResourceById webApi DeleteFunction DELETE For the snippet above we have to add additional preflight Handlers api config api function api function id Before we created our package we always were writing handlers like this router HandleFunc functionResourceRoot webApi PreflightRoot Methods OPTIONS router HandleFunc functionResourceById webApi PreflightByID Methods OPTIONS func webApi WebApiContext PreflightRoot respWriter http ResponseWriter request http Request rest EnableCors amp respWriter respWriter Header Set Access Control Allow Methods POST GET OPTIONS func webApi WebApiContext PreflightByID respWriter http ResponseWriter request http Request rest EnableCors amp respWriter respWriter Header Set Access Control Allow Methods GET PUT DELETE OPTIONS We also should show what the webApi object is and how some of its request handler functions look type WebApiContext struct Db gorm DB passing gorm to Context Config config AppConfig other fields func webApi WebApiContext GetAllFunctions respWriter http ResponseWriter request http Request return here array of functions body omitted func webApi WebApiContext GetFunctionById respWriter http ResponseWriter request http Request return function by id body omitted Let s see how our code changed after we added the library webApi rest WebApiContext Db appContext ModelContext Context Config appContext Config WebApiHandler gr NewWebApiHandler true gr AnyOrigin webApi WebApiHandler Router Use keycloakAuthService KeycloakAuthMiddleware webApi WebApiHandler Router Use r InspectorMiddleware router webApiContext WebApiHandler Router router StrictSlash true function resource webApi WebApiHandler HandleFunc router baseUri function webApi GetAllFunctions GET webApi WebApiHandler HandleFunc router baseUri function find webApi FindFunctions GET Queries query query webApi WebApiHandler HandleFunc router baseUri function name webApi GetFunctionsNames GET webApi WebApiHandler HandleFunc router baseUri function id webApi GetFunctionById GET webApi WebApiHandler HandleFunc router baseUri function id body webApi GetFunctionWithBodyById GET webApi WebApiHandler HandleFunc router baseUri function webApi CreateFunction POST webApi WebApiHandler HandleFunc router baseUri function id webApi UpdateFunction PUT webApi WebApiHandler HandleFunc router baseUri function id webApi DeleteFunction DELETE webApi WebApiHandler HandleFunc router baseUri function filter webApi FilterFunctions GET ConclusionWe made this package not because we have a lot of spare time on our hands but because we were forced to do that because of a huge amount of CORS related errors we were getting every time we worked on something big Now that we have this solution CORS is no longer a problem	2022-03-25 05:15:13

海外TECH	DEV Community	APT sucks, use Nala instead!	https://dev.to/mohammadtaseenkhan/apt-sucks-use-nala-instead-3083	APT sucks use Nala instead canonical url APT sucks use Nala instead APT Documentation What is APT apt is a command line utility for installing updating removing and otherwise managing deb packages on Ubuntu Debian and related Linux distributions It combines the most frequently used commands from the apt get and apt cache tools with different default values of some options apt is designed for interactive use Prefer using apt get and apt cache in your shell scripts as they are backward compatible between the different versions and have more options and features Most of the apt commands must be run as a user with sudo privileges This guide serves as a quick reference for the apt commands Updating package index apt update The APT package index is basically a database that holds records of available packages from the repositories enabled in your system To update the package index run the command below This will pull the latest changes from the APT repositories sudo apt updateAlways update the package index before upgrading or installing new packages Upgrading packages apt upgrade Regularly updating your Linux system is one of the most important aspects of overall system security To upgrade the installed packages to their latest versions run sudo apt upgradeThe command doesn t upgrade packages that require removal of installed packages If you want to upgrade a single package pass the package name sudo apt upgrade package nameIt is always a good idea to configure automatic security updates Full Upgrading apt full upgrade The difference between upgrade and full upgrade is that the later will remove the installed packages if that is needed to upgrade the whole system sudo apt full upgradeBe extra careful when using this command Installing packages apt install Installing packages is as simple as running the following command sudo apt install package nameIf you want to install multiple packages with one command specify them as a space separated list sudo apt install package packageTo install local deb files provide the full path to file Otherwise the command will try to retrieve and install the package from the APT repositories sudo apt install full path file deb Removing Packages apt remove To remove an installed package type the following sudo apt remove package nameYou can also specify multiple packages separated by spaces sudo apt remove package packageThe remove command will uninstall the given packages but it may leave some configuration files behind If you want to remove the package including all configuration files use purge instead of remove sudo apt purge package name Remove Unused Packages apt autoremove Whenever a new package that depends on other packages is installed on the system the package dependencies will be installed too When the package is removed the dependencies will stay on the system This leftover packages are no longer used by anything else and can be removed To remove the unneeded dependencies use the following command sudo apt autoremove Listing Packages apt list The list command allows you to list the available installed and upgradeable packages To list all available packages use the following command sudo apt listThe command will print a list of all packages including information about the versions and architecture of the package To find out whether a specific package is installed you can filter the output with the grep command sudo apt list grep package name To list only the installed packages type sudo apt list installed Getting a list of the upgradeable packages may be useful before actually upgrading the packages sudo apt list upgradeable
