海外TECH	DEV Community	Kubernetes for Startups: Practical Considerations for Your App	https://dev.to/argonaut/kubernetes-for-startups-practical-considerations-for-your-app-370i	Kubernetes for Startups Practical Considerations for Your App What is Kubernetes It all started with the container wars of yore where Apache Mesos Docker Swarm Kubernetes and Hashicorp Nomad fought a bloody battle until there emerged a clear victor Kubernetes originated within Google and significantly more than half of the responders in a CNCF survey reported using Kubernetes in production not considering sample bias from orgs It has market share within the container orchestration space With great power comes great responsibility Uncle BenWith great power comes great complexity AnonymousKubernetes is extremely powerful and that configurability leads to complexity Here are the practical considerations that one must be aware of when dealing with Kubernetes as the deployment target So you have decided to use Kubernetes for your startup This post details what you need to do to have a fully functioning setup This post is opinionated Setup and maintenanceThere are two classes of tools Managed Kubernetes providers like Amazon EKS Google GKE Azure AKS DOKS etc These are managed services by cloud providers Please do not try to manage Kubernetes clusters by yourself using kubeadm or similar unless there is a hard constraint like compliance or on prem deployments Kubernetes wrappers to make working with ks easy a smattering of startups moving ks under the hood Argonaut does this amongst other things Scoping the setup to just the major clouds the configuration process from the UI takes minutes and then another minutes for the cluster itself to be provisioned Command line tools exist to specify the configurations using yaml files Terraform modules can help in provisioning this using IAC paradigms New Kubernetes control plane versions are released every weeks The alpha →beta →prod release cycle for features APIs is around year long The deprecation of older APIs is also approximately the same cycle Installing a recent version of a third party tool eg Grafana can fail on older versions of Kubernetes because of outdated APIs Maintaining a current version of the Kubernetes control plane becomes important for this very functional reason not counting security enhancements and additional features delivered over time Updates of Kubernetes versions can break functioning applications because of deprecated APIs that may be used This needs to be done with utmost care and can be an arduous process every few months This is a major consideration if you don t have someone with the relevant time and expertise for this activity using Kubernetes directly is not recommended Application developer experienceAs a startup you want application developers to go full throttle on building functionality and not worry about infrastructure Using Kubernetes can bring a lot of velocity to the development workflows by enabling scale from day one This is the technology that powers Internet scale companies and provides immense flexibility around scaling rollouts and service discovery while abstracting out the physical infrastructure Here are the major concerns Build Workloads need to be containerized That leads to long build times especially if there is no caching possible enabled for the build A local build might be just a hot reload but these can take many minutes with the container build step included Please use podman kaniko or similar over docker for builds Deploy The deployment experience itself is super neat The complexity of defining the deployment which is usually a one time heavy lift followed by minor modifications for maintenance is pretty high and requires ks specific knowledge Some tools help with the automatic generation of ks manifests for easy use like skaffold devspace dokku and more Debug difference between local and dev environments Replicating bugs from remote environments to local is tough Tools like devspace and telepresence help The former enables a quick build loop between the local and the remote ks environment and can be massively helpful in reducing development time The latter is a lot more magic directing remote traffic to your local laptop but is more complex to work with Debug logging into remote While devspace telepresence and skaffold are nice for remote dev sometimes the easiest thing to do is to login to the remote container for debugging You definitely want to use a Kubernetes dashboard ks lens or ks cli Along with this you can use kubectl exec to open up a shell in the container or use ephemeral containers to attach to a running pod introduced in ks v The latter is the preferred method in dev environments Neither of these should be done in prod environments Autoscaling This is a huge benefit that ks brings Autoscaling can mean one of three things Cluster Nodes This is the number of EC instances required to satisfy the application requirements The cluster autoscaler or karpenter projects are great for this Application Horizontal Scaling Creating more instances of the application to keep up with the load Keda is the tool for this Application Vertical Scaling Increasing resources available to each instance of the application based on load This is not done very much in practice and there aren t any mature tools to help with this beyond the ks built in Monitoring applicationsLogs A logging solution is a must when dealing with ks simply because you should avoid directly accessing prod environments Setting up a logging pipeline is not hard Prometheus Grafana Loki is the simplest self hosted solution while datadog etc provides excellent out of the box experiences but at a literal cost One thing to be wary of is that logs from different instances of the same application are usually treated differently which can be a mixed bag during debugging Self hosting ELK will cause a few days of heartburn before you get it up and running reliably APM Tracing Use your favorite Please avoid tool fragmentation and use the same solution across My personal favorite to get started is self hosting Prometheus Grafana Loki For advanced use cases I like datadog but it is expensive A catch with hosting your own observability stack is that it can lead to fragmentation if you re not careful Monitoring one cluster with a Grafana stack is fine multi cluster setup gets complicated Infra monitoring etc is a whole other ball game with the right permissions and access control requirements that can be hard to wrangle for startups A huge advantage with running applications on ks w r t monitoring is that the whole bunch can be monitored in one shot with little to no changes required by the applications The collection agents usually run as daemonsets collecting container logs from each of the nodes and piping them to the log server with the appropriate labels Works like a charm CostThe big one month per cluster plus whatever compute is used Kubernetes adoption for startups almost certainly increases the cloud bill because there is a month cost associated with just running each cluster on EKS GKE or AKS for uptime SLA However there are some tools that could help with reducing the costs by providing visibility into the utilization of the pods and adjusting resources appropriately like kubecost For very early companies check out lambda container images as a starting point especially if there are only a handful of services and low utilization Setup evolutionHere are some things you will eventually need to do over the next few years Setup multiple clusters across regions and connect them to operate as a single entity as far as apps are concerned This needs a service mesh like linkerd Setup policy around what resource requirements can be requested by an app per environment OPA and gatekeeper or kyverno can help Setup access control for who can create or modify apps Setup a VPN solution Accrete tools to help with ks management over time Have a dedicated infra team To be clear these are NOT negatives The alternative would be to build immature tooling in house to replicate all this functionality at an even greater investment of time and effort Closing notesUse Kubernetes as a startup if you have cloud credits and more than services and a couple of environments The overhead with using Kubernetes is real Use a product that can help with overall management Use lambda container images if you have services and low utilization Use Argonaut All of the above are either a part of Argonaut already or will soon be We support Lambdas and Kubernetes runtimes and we can help you make the right choice for your startup Sometimes that might be to not use Argonaut and we will tell you that Check out our docs here	2022-04-22 08:27:48

海外TECH	DEV Community	Going serverless with custom portal for D365 environments	https://dev.to/rainforss/going-serverless-with-custom-portal-for-d365-environments-2e4j	Going serverless with custom portal for D environmentsIn the first article of the series I briefly addressed the pros and cons of Microsoft s Power Apps Portal and the reason why it might not be a cost efficient product for companies at all scales who need to open a controlled portal to a specific piece of their D data The standalone web server which is supporting the Power Apps Portal plays a major role depicting the product as a non optimal solution for smaller organizations Most of the time a business operating in a single territory or territories in a close proximity does not need a web server which continuously listens for incoming requests since the traffic could be very localized and patterned For example Calgary Canucks Rugby Union a non profit organization operating in Calgary tries to expose some matches information stored in Dynamics through Power Apps Portal It is very likely that traffic would hit the portal some time right after the rugby matches and rapidly die down until the next match result is posted During this quiet period between the matches utilization rate of the portal web server would be very low so the server will stay in an idle state awaiting requests Therefore smaller organizations using Power Apps Portal are essentially paying for a web server that s idling for more than of the time One can propose the use of a lower tier web server like what Heroku offers for the free hosting which enters a sleep mode if no traffic come in for a period of time but I am going to take it further by adopting a serverless solution removing a traditional server from the scene entirely Being a huge fan of NextJS an opinionated framework based on ReactJS and serverless functions I decided to use NextJS to power the front end of my custom portal and NextJS API routes together with Vercel s serverless functions to orchestrate my portal s back end services In short serverless functions are invoked functions running in servers offered by larger organizations AWS Azure Google Vercel etc whose profession is in cloud computing Using serverless functions to access other web services e g making HTTP requests to remote servers the front end application is enabled to do its job providing user interactions without the need of a dedicated traditional server With the self owned traditional server out of the solution smaller organizations can focus on delivering user centric content instead of sparing resources on maintaining a web server Now you might be asking how do serverless functions communicate with Dynamics environments to retrieve the data for the front end web application Making use of Azure App Registration and a application user in Dynamics the serverless functions can obtain access tokens issued by Azure Active Directory OAuth service Adding the access token to HTTP requests made by serverless functions the web application is now authenticated and authorized as the application user to perform CRUD operations allowed by security role configurations This is just a high level overview of the integration feel free to ask if you want to know more about the details Using the serverless functions I was able to create a custom D portal with even registration and authentication functionalities for Calgary Canucks Rugby Calgary Canucks Rugby Union How does serverless function save companies money Serverless functions are on demand services provided by cloud computing companies so you only need to pay for the functions being invoked In the previously illustrated scenario Calgary Canucks Rugby simply wouldn t have any expenditure when no traffic is hitting hence no back end services involved the public facing website if serverless function was the back end solution To make the serverless solution even better companies such as Vercel are also offering free serverless function usage per month and it is actually very rare for front end applications with less traffic to use up the monthly quota By adopting the serverless function solution for a custom Dynamics portal Calgary Canucks Rugby and other similar organizations can save up a good amount of budget for other essential operations simply because they wouldn t be paying for web servers and web server maintenance Sorry webmasters and IT administrators In case you are wondering this article is not sponsored by Vercel or NextJS I simply love Vercel and NextJS that much	2022-04-22 08:23:21
海外TECH	DEV Community	React Native App Development Services: Top Reasons to Opt	https://dev.to/jamesnicholasjr/react-native-app-development-services-top-reasons-to-opt-3ba2	React Native App Development Services Top Reasons to OptThe proliferation of mobile applications particularly in the previous decade has boosted the need for and usage of cross platform app development React Native is a well known cross platform application development framework The React Native app development services are being widely adopted by so many businesses worldwide React Native is a flexible framework that can be used to create applications of different sizes and in a variety of industries It allows the creation of hybrid mobile apps that employ both old and modern technologies Developers may offer customized React development services to create web apps for Mac and Windows platforms as well as cross platform Android and iOS mobile apps You might be curious to learn why businesses and developers use React Native app development services for mobile app development Many well known companies have already deployed this framework with no failures Prominent brands including Skype UberEats Facebook Instagram Pinterest Vogue Tesla Bloomberg and others have embraced React Native on iOS and Android platforms Here are some of the remarkable reasons demonstrating why choosing React development service is the best thing to do Why Choose React Native App Development Services Rapid DevelopmentReact Native s key advantages include agility faster app development and a better overall user experience It gives customers a more natural experience Since the same code can be readily deployed on both the iOS and Android platforms the development cycle can be cut in half As a result the time and cost of development are decreased React Native reduces development time and costs while maintaining project quality and productivity In addition the requirement for additional developers has significantly decreased Cost efficientNew businesses and startups must develop their online presence rapidly and on a small budget to be successful At this moment React Native app development services come into play Using the React Native framework will save you both time and money This structure will help you achieve larger profits while also building a solid consumer base Reusable CodebaseCross platform mobile app development is based on the idea that the code developed may be utilized for both iOS and Android apps The same idea applies to React Native It works on the principle of write once publish everywhere The developers will no longer need to create distinct designs for each platform Furthermore if a business already has a web app it may be possible to reuse a large portion of the code to create a mobile app Multiple Results and SupplenessReact Native mobile app development which is based on concepts allows you to perform complicated operations with simple scripts To simplify the amount of code necessary to design and run ReactJS this framework takes advantage of Facebook s UI library The ability to Live Reload is critical in the development of a React Native mobile app It enables code changes and alterations in real time while the application is running Easy to LearnCompared to other frameworks React Native is much easier to learn and adopt Learning React Native is a breeze for those who are already comfortable with JavaScript No need to learn new languages or write difficult code because of the framework In addition React Native has a strong developer community that is enthusiastic about it This community may assist developers in resolving any issue no matter how little promptly The community s unique React Native programming talents and tools may potentially be useful to developers Stable and Highly Performant App DevelopmentThe codebase of React Native uses a simpler binding method As a result before making any modifications you must first change the status of one of the objects Other techniques for cross platform development will not help you develop more robust and trustworthy applications React Native is an amazing alternative for creating a brand new mobile app from scratch It can be used to supplement existing native apps with a single view or user flow In just a few minutes you can add new React Native based features views screens and more Effortless DebuggingDebugging takes a lot of time Developers must spend hours studying their code in order to identify and correct flaws The work gets substantially more difficult when there is a blundering syntax problem that is not obvious React development service comes to the rescue in this situation The team will spend less time looking for problems now that they are using the cross platform app development framework Since it is built on a single codebase a single bug fix is all that is necessary to bring the entire system back to life Furthermore the framework includes debugging tools such as Nuclide and console org to aid with the process Closing ThoughtsWhen you balance the pros and downsides of React Native app development services you will see that the positives much exceed the negatives Taking the benefits into account it is evident that React Native has a promising future in cross platform app development To summarize you know where to go if you want to develop a user friendly multidimensional mobile app that is always available For everything from start ups to well established businesses people are flocking to mobile applications rather than websites So choose your React development service provider and flourish in the market	2022-04-22 08:23:03

海外TECH	DEV Community	What is logic programming and how does it work?	https://dev.to/annoh_karlgusta/what-is-logic-programming-and-how-does-it-work-2fhc	What is logic programming and how does it work Logic programming is a type of computer programming in which program statements convey facts and rules about circumstances using a formal logic framework For example H is a state as a logic clause with a head and a body if B B and B are true The programmer must instruct the machine on how to make decisions based on mathematical logic In logical programming for example the use of a mathematical algorithm Computer programs are made up of code that tells the computer how to do specific things However the computer will eventually be obliged to make a decision about how to proceed It will be unable to complete its present task without the knowledge Logic programming solves these challenges by giving the computer instructions that allow it to make a logical decision about how to respond to a particular situation Studying logic is similar to learning math It s a skill that must be learned via practice This could be accomplished directly through programming or indirectly through logic puzzles The following are the most important aspects of the skill You should be aware of the formal moves that you can make in your system Breaking down your problem into manageable chunks so that each aspect may be addressed separately Understanding how to put the movements together to reach where you want to go It may appear straightforward but as everyone who has done mathematics knows applying simple rules may be difficult at times Because the underlying skills are so similar doing some math can surely assist The important aspect is to really do something ーto solve problems Alternatively practicing formal logic problem sets would be beneficial in honing these abilities Learning to solve difficulties for yourself is the most important aspect Watching tutorials or copying other people s solutions will never get you where you need to be While seeing solutions is beneficial doing the work yourself should be the focus of your practice During the Year of Code in America many schools throughout the world began introducing a computer programming skill element into the school day Children can learn the principles of computer functioning through this type of education If they can get a computer to do what they want kids can be proud of themselves This foundation can help children prepare for a lifetime of successful technology use and management Computational thinking is the capacity to express your thoughts in a systematic and logical manner This brain process is analogous to how a machine follows instructions step by step It s also the meticulous process of creating and solving problems that a computer could repeat To address problems software engineers computer programmers and logistics professionals adopt this approach of thinking Computational thinking encompasses advanced mathematics algorithm development and reasoning To develop computational thinking consider a problem and break it down into single action phases Each of these procedures is carried out as quickly as possible See you soon	2022-04-22 08:20:46

consumable In App PurchasesWhen developing mobile applications you may want to generate revenue with your app According to the latest Sensor Tower report consumable and non consumable in app purchases are some of the most commonly used monetization mechanics ーespecially in games with Ad Removal Games with this monetization method account for of all games In this article we ll take a closer look at features of in app purchases what s the difference between consumable and non consumable IAPs and how to set it up with Qonversion Types of In app PurchasesIAPs can be used in a number of ways For example to add features remove ads or purchase in game currency But which type of purchase should you use for each purpose There are two types of in app purchases that can be used for iOS and Android mobile apps Non consumable items The idea is that they could be purchased only once It is permanently associated with the user s store account Examples are purchasing game levels race tracks and extra app features and yes ad removal Consumable items can be purchased multiple times It could be used up during the life of the application Examples are in game currency and extras Differences Between Google and Apple In app PurchasesGoogle makes no difference between non consumable and consumable in app purchases when creating a product However Apple requires developers to specify the type of in app purchase in App Store Connect How to Setup Consumable and Non consumable In app PurchasesLet s assume we develop a racing game for iOS and Android Our app allows users to unlock premium race tracks non consumable item once a track is purchased a user gets access to it forever and purchase extra health for a car consumable item the user should be able to buy health every time he needs it Qonversion allows handling all types of in app purchases including non subscription products The following example describes the process of integrating in app purchases into mobile apps with Qonversion Before we get started with the creation of consumable and non consumable purchases make sure that you already have a Qonversion account and have created your project and register the app PreparationSuppose we have already created in app purchases in Google Play Console and App Store Connect with the following IDs android premium track android extra health and ios premium track ios extra health accordingly Let s create Products in the Qonversion dashboard Then we should create a Permission and link it to the premium track product Premium permission will unlock access to the track after its purchase For the extra health product we don t need to create a permission Let s also create an Offering to be able to change the products set remotely without releasing app updates Attach created products to the offering How to Provide a Lifetime Access With Non consumable In App Purchases Displaying productsDisplay products for sale to the user iOS Qonversion offerings offerings error in if error nil Handle the error here let offering offerings offering forIdentifier standard offering if let product offering product forIdentifier premium track Display the product for sale Android Qonversion offerings object QonversionOfferingsCallback override fun onSuccess offerings QOfferings val offering offerings offeringForID standard offering offering productForID premium track let product gt Display the product for sale override fun onError error QonversionError Handle the error here Making PurchasesWhen the user is ready to purchase the product start a purchase flow with the following method iOS Qonversion purchaseProduct product permissions error isCancelled in if let premium Qonversion Permission permissions premium premium isActive Successful purchase Unlock premium content Android Qonversion purchase context product callback object QonversionPermissionsCallback override fun onSuccess permissions Map lt String QPermission gt val premiumPermission permissions premium if premiumPermission null amp amp premiumPermission isActive Successful purchase Unlock premium content override fun onError error QonversionError Handle the error here Every time you want to know whether the user has access to the premium content you should call the checkPermissions method Once the product has been successfully purchased and the permission has become active you should not allow the user to purchase the product again The user has a lifetime access since now Provide an Access With Consumable In app Purchases Displaying productsDisplay products for sale to the user iOS Qonversion offerings offerings error in if error nil Handle the error here let offering offerings offering forIdentifier standard offering if let product offering product forIdentifier extra health Display the product for sale Android Qonversion offerings object QonversionOfferingsCallback override fun onSuccess offerings QOfferings val offering offerings offeringForID standard offering offering productForID extra health let product amp gt Display the product for sale override fun onError error QonversionError Handle the error here Making purchasesWhen the user is ready to purchase the product start a purchase flow with the following method iOS Qonversion purchaseProduct product permissions error isCancelled in if error Successful purchase Unlock premium content Android Qonversion purchase context product callback object QonversionPermissionsCallback override fun onSuccess permissions Map lt String QPermission gt Successful purchase Unlock content override fun onError error QonversionError Handle the error here To unlock content you don t have to check permissions Instead you should rely on a successful result i e when there is no error Note The app has to remember the state of the purchased product how many units were purchased and give access accordingly For instance if the user purchased units of extra health and then used you should consider it and demonstrate the actual balance of pieces of health within your app So just remaining pieces will be available for your user to purchase ConclusionIn this blogpost we took a closer look on how to set up consumable and non consumable purchases As you can see the process is pretty simple Once you ve implemented in app purchases don t forget to use the analytics tools to measure how much revenue each of your products brings	2022-04-22 08:18:32
