    Reading the standard library will give you ideas/insight about various Go idiomatic patterns/approaches, and you can see a full website/API implementation in the pkg.go.dev repository (https://github.com/golang/pkgsite). Projects like https://github.com/etcd-io/etcd may be interesting too.
  • Fault Tolerance in Distributed Systems: Strategies and Case Studies
    4 projects | dev.to | 18 Oct 2023
    Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.
  • The Complete Microservices Guide

    Service Discovery: Microservices need to discover and communicate with each other dynamically. Service discovery tools like etcd, Consul, or Kubernetes built-in service discovery mechanisms help locate and connect to microservices running on different nodes within the infrastructure.
  • How is Apache APISIX Fast?
    6 projects | dev.to | 13 Sep 2023
    APISIX uses etcd to store and synchronize configurations.
  • Apache APISIX without etcd
    3 projects | dev.to | 27 Jul 2023
    etcd is an excellent key-value distributed database used internally by Kubernetes and managed by the CNCF. It's a great option, and that's the reason why Apache APISIX uses it too. Yet, it's not devoid of issues.
  • Evaluating Apache APISIX vs. Spring Cloud Gateway
    3 projects | dev.to | 22 Jun 2023
    In traditional mode, APISIX stores its configuration in etcd. APISIX offers a rich API to access and update the configuration, the Admin API. In standalone mode, the configuration is just plain YAML. It's the approach for GitOps practitioners: you'd store your configuration in a Git repo, watch it via your favorite tool (e.g., Argo CD or Tekton), and the latter would propagate the changes to APISIX nodes upon changes. APISIX reloads its configuration every second or so.

  • mTLS everywhere!
    5 projects | dev.to | 23 Mar 2023
    Apache APISIX is an API Gateway. By default, it stores its configuration in etcd, a distributed key-value store - the same one used by Kubernetes. Note that in real-world scenarios, we should set up etcd clustering to improve the resiliency of the solution. For this post, we will limit ourselves to a single etcd instance. Apache APISIX offers an admin API via HTTP endpoints. Finally, the gateway forwards calls from the client to an upstream. Here's an overview of the architecture and the required certificates:
  • Why is the principle stating that "interfaces should belong to the package that uses values of the interface type, not the package that implements those values" sometimes violated?
    2 projects | /r/golang | 19 Feb 2023
    While exploring popular projects such as etcd and especially traefik, I noticed a violation of the principle that states "interfaces should belong to the package that uses values of the interface type, not the package that implements those values." For example, Here we can see that ManagerFactory import Registry interface that placed here and implementations of this interface in the same package, which violates the aforementioned principle. Even if the interface is simply a specification, it should still be defined on the consumer side. Is it considered bad practice to follow what traefik does in this case or I doesn't understand somthing? P.S. I'm newcomer, so sorry if it's silly question.

    In this project, you will understand and get hands on experience around the entire concept around CI/CD from applications perspective. To fully gain real expertise around this idea, it is best to see it in action across different programming languages and from the platform perspective too. From the application perspective, we will be focusing on PHP here; there are more projects ahead that are based on Java, Node.js, .Net and Python. By the time you start working on Terraform, Docker and Kubernetes projects, you will get to see the platform perspective of CI/CD in action.

    The single most important development in hosting since the invention of EC2 is defined by its own 3-letter acronym: k8s. Kubernetes has won the “container orchestrator” space, becoming the default way that teams across industries are managing their compute nodes and scheduling their workloads, from data pipelines to web services.
  • The Road To Kubernetes: How Older Technologies Add Up
    5 projects | dev.to | 5 Feb 2024
    Kubernetes was first released on September 9, 2014. This release timeline is part of what helped it gain a foothold over Docker Swarm. It was an open source version of an internal Google project. Features of container orchestration were presented in a more modular fashion along with scaling functionality. You can chose how your networking stack works, your load balancing, container runtime, and filesystem interfaces. Availability of an API allowed for more programmatic interactions with orchestration, making it tie in very well with CI/CD solutions. However, the big issue it has is complexity of setup. Putting together a Kubernetes cluster with basic functionality is certainly no easy feat.

  • Why bad scientific code beats code following "best practices"
    3 projects | news.ycombinator.com | 6 Jan 2024
    There are some things that should be in one long function (or method).

    Consider dealing with the output of a (lexical) tokeniser. It is much easier to maintain a massive switch statement (or a bunch of ifs/elseifs) to handle each token, with calls to other functions to do the actual processing, such that each case is just a token and a function call. Grouping them in some way not required by the code is an illusory "gain": it hides the complexity of the actual function in a bunch of files you don't look at, when this is not a natural abstraction of the problem at all and when those files introduce extra layers of flow control where tricky bugs can hide. Or see the "PLEASE DO NOT ATTEMPT TO SIMPLIFY THIS CODE" comment from the Kubernetes source[0]. A 300 line function that does one thing and which cannot be usefully divided into smaller units is more maintainable than any alternative. Attempting to break it up will make it worse.

    That being said, I agree that nearly all 300 line functions in the wild are not like this.
