海外TECH	DEV Community	Kubernetes: What It Is, How It Works, and Why It's A Game changer	https://dev.to/pramit_marattha/kubernetes-what-it-is-how-it-works-and-why-its-a-game-changer-15pg	Kubernetes What It Is How It Works and Why It x s A Game changer IntroductionKubernetes which was first released on June th has quickly established itself as the de facto industry standard for orchestrating containers According to Red Hat s State of Enterprise Open Source report of the IT leaders polled said their organizations use Kubernetes This figure is expected to rise further as nearly one third of the polled IT leaders said they planned to significantly increase their use of containers over the next months and there have been over a million downloads of this particular tool so far But what exactly is Kubernetes How does it work And why should you care about it In this article I ll try to answer those questionsーand more What is Kubernetes Kubernetes is an open source container management system It was originally developed by Google engineers to help them manage large scale containerized applications and it has since become the most popular solution for running containers in production Kubernetes is a platform for running containerized applications It s designed to make it easier to deploy scale and manage those applicationsーwhich are usually made up of multiple containers that work together to provide features like web serving or data processing Kubernetes can be thought of as a distributed system for managing containerized applications at large scale Kubernetes clusters are made up of one or more master nodes that control worker nodes which run tasks on behalf of clients through API requests sent over HTTP or gRPC protocols The master node s manage and schedule the containers that make up each application APIs are provided for monitoring logging and diagnostics as well as configuration for applications running on the cluster Is Kubernetes built on top of other open source projects Yes Kubernetes in fact relies on a number of other free and open source software packages As a base it relies on the Docker container runtime and the CoreOS Linux distribution and it utilizes other open source projects for a number of its components such as etcd for distributed key value storage The tool s core and control plane are both built in GO programming language making it a completely Go based application Kubernetes itself is an open source project and has been used as a building block for other open source projects Kubernetes was originally developed by Google and donated to the Cloud Native Computing Foundation CNCF in Red Hat took over as the maintainer of Kubernetes through releases and then released version which marked a new beginning for Kubernetes as a fully community owned project It is now maintained by a community of developers and users around the world How does Kubernetes work Kubernetes is used for automating the deployment scaling and management of containerized applications It supports multiple platforms and infrastructure providers Kubernetes provides two primary things A way to manage your container clusters A way to get data from one place to another such as from a database to an application Kubernetes also provides a lot of features that make it easier to manage your cluster of containers It includes a built in UI interface allowing you to manage everything from a single location It also has automatic recovery and self healing capabilities so if something goes wrong with one of your nodes like an outage Kubernetes will automatically restart it when the issue is resolved Not only that it is also highly configurable You can use it to deploy any type of application from web servers to databases It has support for many different cloud environments including Google Cloud Platform GCP Amazon Web Services AWS and Microsoft Azure What and why containers  Before we dive deep into kubernetes let s talk about containers first Containers are a way of packaging and running applications in a portable and isolated environment They allow applications to be run in a consistent and predictable manner regardless of the underlying infrastructure This makes it easier to develop test and deploy applications as well as to run multiple applications on the same host without them interfering with each other Containers have become popular recently because they provide a number of benefits over traditional deployment methods For example they are Lightweight A container is a single process that runs on a machine and includes only the libraries configuration files and other dependencies it needs to run This means containers can be started quickly as there is no need for the initial setup of a virtual machine VM which can take time depending on its size Portable Containers can be moved from one environment to another with minimal effort because their entire runtime state is included in each container Containers also provide an additional layer of abstraction between an application s code and the underlying OS kernel making it easier to move applications between servers while maintaining compatibility with all dependencies installed inside themーyou don t have to worry about incompatibilities between your app s software stack and whatever server you choose Isolated To keep containers separate from each other on the same host machine they run in separate namespacesーthis means that even if two or more processes share an IP address outside their respective namespaces they won t necessarily be able to access each other s files or ports Using this approach reduces port conflicts since network services won t need specific ports opened up on hosts just so the operating system knows where to send data destined for certain applications The level of isolation provided by containers can vary depending on the container runtime and the specific configuration of the container Some container runtimes such as Docker provide a high level of isolation by default while others may provide more limited isolation However in general containers are designed to provide a certain degree of isolation to ensure that they can run independently and reliably This makes it easier to set up and manage complex infrastructures with many different applications all running on the same host You can also run multiple containers on the same hardware with minimal overhead since they re isolated from each other How do containers compare to virtual machines Containers are more lightweight than virtual machines VMs in that you don t need to run an entire operating system Containers are also more portable as they re typically created from a Dockerfile or other source code and can be moved around easily on your machine Containers are more efficient than virtual machines because they allow you to send just the right amount of data over the network This is especially important for microservices which need to share resources but often can t because different users have different needs like different database sizes Containers are more scalable than virtual machines because it s easier to increase their size as needed all one has to do is allocate more resources RAM and or CPU cycles when deploying new containers onto existing hosts with Kubernetes replication controller feature set built in for this purpose Containers are kind of safer than virtual machines because there isn t much that can go wrong with them while they re running For example each container instance can start new processes while also handling requests from programs running outside of that container instance using its own IP address This is very different from how things are handled inside a virtual machine where processes running on the same host share resources with one another With containers you can achieve true cloud portabilityContainers can indeed provide a high degree of portability and allow applications to be easily moved between different environments This is one of the key benefits of using containers as it enables organizations to develop and deploy applications consistently and predictably regardless of the underlying infrastructure Containers provide this portability by packaging the application and its dependencies into a self contained unit that can quickly move and run on any host with the necessary container runtime This means an application can be developed and tested on one system and then run in production on another without any changes or modifications Additionally containers are designed to be portable and run on various infrastructures from on premises data centers to public clouds This allows organizations to choose the best environment for their applications and to move them between different environments if needed quickly Rise of containers is promoting adoption of KubernetesThe rise of containers has indeed played a significant role in promoting the adoption of Kubernetes Kubernetes is a container orchestration platform which means that it is designed to manage and deploy large numbers of containers across a cluster of machines As containers have become more widely used there has been a growing need for effective ways to manage and deploy them at scale This has led to the rise of Kubernetes and other container orchestration platforms which provide the necessary tools and features for managing and deploying large numbers of containers Additionally Kubernetes has been designed to work seamlessly with containers and to provide a consistent and predictable way to run and manage containerized applications This has made it an attractive choice for organizations using containers and looking for a powerful and flexible platform for managing and deploying their applications Primary components that make up kubernetesKubernetes is currently maintained by Google Red Hat and other BIG organizations Kubernetes provides a highly scalable container management solution for any cloud or on premises infrastructure The platform consists of several main components Kubernetes Master It is the central control plane for a Kubernetes cluster It is responsible for managing the cluster and coordinating the activities of the Nodes The Master includes several components such as the API server which exposes the Kubernetes API and allows other components to interact with the cluster the Scheduler which determines where to run each application and the Controller Manager which provides various cluster level functions such as replication and self healing Kubernetes Node The Nodes are the worker machines in a Kubernetes cluster They run the applications and workloads that are managed by the Master Each Node includes the Kubernetes runtime which is responsible for running the containers and providing the necessary resources and isolation The Nodes communicate with the Master to receive instructions and to report on the status of their workloads Kubernetes Dashboard A flexible user interface that provides a graphical view of cluster resources and allows users to manage and control workloads Other key components of Kubernetes include the etcd distributed key value store which is used for storing the cluster s configuration and state the kubelet which is the primary agent that runs on each Node and manages the containers and the kubectl command line interface which is used to interact with the cluster and manage its applications Game changing implications of KubernetesKubernetes has several game changing implications for how applications are developed deployed and managed Some of the critical implications of Kubernetes include the following Increased agility and speed Kubernetes provides a powerful and flexible platform for running and managing applications which allows organizations to deploy and update applications quickly and easily This can reduce the time and effort required to develop and deploy applications and enable organizations to respond more rapidly to changing business needs Improved scalability and reliability Kubernetes includes features such as self healing and autoscaling which can help to ensure that applications are always available and running at the required capacity This can improve the reliability and performance of applications and help organizations handle sudden increases in traffic or workloads Reduced operational overhead Kubernetes provides a consistent and centralized way to manage and deploy applications across a cluster of machines This can simplify the operational complexity of running and managing applications and help organizations reduce the time and effort required to maintain their applications Greater portability and flexibility Kubernetes is designed to be portable and run on various infrastructures from on premises data centers to public clouds This can give organizations greater flexibility and choice in where they run their applications and make it easier to move applications between different environments Overall Kubernetes has the potential to significantly change the way applications are developed deployed and managed and can provide organizations with many benefits in terms of agility scalability reliability and simplicity These skills are becoming increasingly important for software engineers and other IT professionals The use of Kubernetes and containers is growing in importance for software developers and other IT professionals because to their widespread adoption and the many advantages they offer for creating deploying and maintaining applications Some of the reasons why Kubernetes and containers skills are becoming increasingly important include Kubernetes help you manage your containerized applications It helps you run and scale your applications and it helps you do it at a low cost It is based on the idea that applications should be constructed as small individual pieces containers rather than large monolithic programs In a containerized environment you don t worry about individual machines instead you worry about how to run applications and services across potentially thousands of machines Kubernetes also offers built in tools for managing applications and services across potentially thousands of machines For example You can create groups of containers known as pods on which an application depends by defining labels in its manifest file then Kubernetes will ensure they re always running together when needed by putting them into the same pod if possible Your pods can also be distributed across multiple hosts to provide automatic high availability or load balancing If one host fails or becomes unavailable for some reason due to hardware problems or network connectivity issues Kubernetes will automatically move any pods running there over to another machine so they can continue running without interruption Kubernetes can help with Orchestration and DeploymentKubernetes can help with orchestration and deployment in several ways Some of the key ways in which Kubernetes can assist with these tasks include Automated deployment and updates Kubernetes provides a declarative approach to application deployment which means that users define their applications desired state and Kubernetes ensures that the application is running as expected This can make deploying and updating applications easier as users don t need to worry about the specific steps required to bring the application up or down Rolling updates and rollbacks Kubernetes allows users to perform rolling updates and rollbacks which means that they can update their applications incrementally and in a controlled manner This can help reduce the risk of downtime or other issues during deployments and make it easier to recover from problems if they occur Self healing and autoscaling Kubernetes includes features such as self healing and autoscaling which can help to ensure that applications are always running and available If a container or application fails Kubernetes will automatically replace it and if the workload increases Kubernetes will automatically scale the application to meet the demand This can improve the reliability and performance of applications and can help to reduce the operational overhead of managing them Scheduling and resource management Kubernetes provides a robust scheduling and resource management system allowing users to specify their applications requirements and constraints and let Kubernetes handle the details of running and managing the applications This can make it easier to deploy and manage applications at scale and help optimize the use of resources in the cluster Overall Kubernetes is designed to provide many benefits for orchestration and deployment and help organizations develop deploy and manage applications more efficiently and reliably Google Amazon and Microsoft are all getting behind KubernetesKubernetes has been around for years but it has only recently gained popularity as a tool for managing cloud native applications It s also become a way for vendors to differentiate themselves from their competitors and gain an edge in the highly competitive cloud market Yes Google Amazon and Microsoft are all supporting Kubernetes in various ways Google is the original creator of Kubernetes and continues to be a significant contributor to the project Google offers Kubernetes as a service through its Google Kubernetes Engine GKE which allows users to easily create and manage Kubernetes clusters on the Google Cloud Platform Google also provides support and tools for using Kubernetes on its cloud platform and offers training and certification for Kubernetes Amazon is also a significant supporter of Kubernetes Amazon offers Kubernetes as a service through its Amazon Elastic Container Service for Kubernetes EKS which allows users to create and manage Kubernetes clusters on the Amazon Web Services AWS cloud platform Amazon also provides tools and support for using Kubernetes on its cloud platform and offers training and certification for Kubernetes Microsoft is also supporting Kubernetes Microsoft offers Kubernetes as a service through its Azure Kubernetes Service AKS which allows users to create and manage Kubernetes clusters on the Microsoft Azure cloud platform Microsoft also provides tools and support for using Kubernetes on its cloud platform and offers training and certification for Kubernetes Overall Kubernetes is a powerful tool that can greatly simplify the process of deploying and managing containerized applications in the cloud It s a game changer because it allows developers to build deploy and manage their applications in a more efficient and cost effective way without having to worry about the underlying infrastructure ConclusionHopefully this article has helped you understand what Kubernetes is and why it s an important technology I have covered all the basic concepts not all but just a brief concept of Kubernetes along with its key featuresーnow it s time for you to go ahead and try out some of these things for yourself Begin here	2022-12-03 15:21:31

海外TECH	DEV Community	Apollo Server v4 Breaking Changes. Time to move away?	https://dev.to/gethackteam/apollo-server-v4-breaking-changes-time-to-move-away-3fli	Apollo Server v Breaking Changes Time to move away Apollo Server has been the go to JavaScript library for building GraphQL servers for the last half decade But almost every year there are breaking changes and the latest version is no exception Not only did they announce breaking changes they also announced that Apollo will drop support for Apollo Server v and v as early as October In this article I will explain the breaking changes and why it might be time to move away from Apollo Server Click the image below to watch the YouTube video version of this blog post Biggest Breaking ChangesLet s look at the most significant breaking changes in Apollo Server v Together with these breaking changes a migration path from earlier versions of Apollo Server was also published in the documentation We recommend that all users of Apollo Server upgrade to Apollo Server as soon as possible Apollo Server and Apollo Server are deprecated with an end of life date of October nd Apollo Server v Migration Guide New project structureApollo Server v is the latest version of Apollo Server and is replacing Apollo Server v and v As part of this update they ve bundled some packages in apollo server to replace the apollo server package Part of this is the apollo server express package the most popular package for building GraphQL servers in Node js which is now integrated into the apollo server package Thus if you want to use Apollo Server v you must follow the migration guide and update your code to use the new packages As shown in the migration guide flowchart below This seems like a minor deal unless you re not using Express as your web framework And an important note here is that Express GraphQL is being deprecated by the GraphQL Foundation So if you re using Express for a GraphQL API you should move away from it anyway Dropped support for other web frameworksNow that Express is the default framework for running the GraphQL server Apollo decided to remove support for all other web frameworks This means Apollo is forcing developers to use Express to run their GraphQL servers This is a big change as Apollo Server v and v allowed you to build on top of the apollo server packages such as apollo server fastify or apollo server koa This is a huge change as it means you can no longer use Koa or Fastify to run your GraphQL servers unless someone builds a new package for it Until someone decides to build a new package for the web framework you use you re stuck with Apollo Server v which is deprecated and will be end of life in October Updated concept of dataSourcesApollo Server v has a new concept of dataSources In Apollo Server v and v you could use the dataSources property to pass in an object with all of your data sources This is no longer the case in Apollo Server v Instead you will need to create a class that extends the DataSource class and then pass in an array of instances of this class to the dataSources property As a side effect of this change Apollo deprecated the data source implementations created for SQL MongoDB and Firestore Similar to the web framework plugins you will need to make your own data source implementation for these data sources What else has changed Besides no longer supporting any other web framework than Express there are a a lot of other breaking changes Not all of them are bad and the new Apollo Server v seems to be fixing a lot of tech debt the team has been building up over the years For example Apollo Server v has better TypeScript support than previous versions And the deprecation of ApolloError in favor of GraphQLError from the graphql package is a good step forward to keep Apollo Server more in line with other libraries to build your GraphQL API Should I move away from Apollo Server It s entirely up to you But from a Reddit post of the Apollo team it seems the next backwards incompatible release of Apollo Server will be Apollo Server v in spring To me that just shows that Apollo Server is not a stable library to build your GraphQL API And if you re building a GraphQL API for a company you don t want to be stuck with a library that is not stable and will be deprecated every few years That said if you are using Express you can easily upgrade to Apollo Server v Keeping in mind that express graphql has been deprecated as well If you re using Koa or Fastify you can still use Apollo Server v until October You re out of luck if you re using any other web framework You will either need to switch to Express stay on Apollo Server v or wait for community support for the web framework you re using In that case consider moving away from Apollo Server When moving away from Apollo Server and you re looking for a replacement built with JavaScript or TypeScript let me give you some options If you want to keep building your GraphQL API schema first you might want to consider Mercurius which relies on Fastify or GraphQL Yoga If you re going to build your GraphQL API code or resolver first have a look at TypeGraphQL or Nexus Alternatively there are great GraphQL as a Service solutions such as StepZen in case you no longer want to build maintain and host your own GraphQL API You can learn more about the differences between schema first code resolver first or using a GraphQL as a Service in this recording of my talk at GraphQL Galaxy Are you using Apollo Server What are your thoughts on the breaking changes Let me know on Twitter at gethackteam This post was
