Golang Practice Series

Introduction

Golang (or Go) is an open-source programming language developed by Google in 2007 and officially launched in 2009 by leading engineers including Robert Griesemer, Rob Pike and Ken Thompson. Go was designed to solve problems regarding performance, source code complexity and system scalability in the Cloud Native era.

Advantages

  • High performance (Compiled Language): Go compiles directly into machine code without going through an intermediate execution environment like JVM, resulting in extremely fast execution speeds and very low hardware resource consumption.
  • Superior asynchronous processing (Concurrency): Go possesses a super-lightweight Goroutine mechanism (costing only about 2KB of initial memory compared to several MB for traditional Threads) combined with Channels, allowing for easy handling of millions of concurrent connections.
  • Simple syntax, easy to learn: Go syntax is simplified, eliminating complex concepts (such as class inheritance, function overloading) to help developers quickly grasp and maintain clean source code.
  • Optimized for Cloud Native & Microservices: Go is the primary language creating foundational tools of the Cloud world such as Docker, Kubernetes, Terraform or Prometheus.
  • Optimized Garbage Collector: Go integrates a built-in automatic garbage collector with super-low latency (sub-millisecond latency), helping manage memory safely without interrupting the application.
  • Extremely fast compilation time: Go compilation speed is almost instantaneous, providing a smooth development experience similar to interpreted languages (Python/JS) while still maintaining the performance of C/C++.

Introduction This is a comprehensive page about the technologies I have shared in series format. You can view brief introductions and links to directly access each series you are interested in. In the field of software development, to deploy a product from the initial idea to its release, the standard process typically involves several stages as follows: Database : Designing and implementing the database according to business requirements, storing data during the system's operation. Backend : Handling the main logic of the system, communicating with the database and services. Frontend : Building the interface for users to interact with the system, which could be a desktop, mobile, or web application. This usually includes implementing UI/UX and integrating APIs from the backend. DevOps : Deploying the system for use, which can be done on a server or in the cloud. Testing : Applying testing methods to ensure the product meets the standards for release. Of course, these are just stan...

Understanding React Server Component

Image
Introduction As most of us already know, React enables us to break down interfaces into independent parts called Components, facilitating reuse and customization. Currently, React Components are divided into two main types: Client Components : widely used in Client Side Rendering (CSR) applications. Server Components : a new type of component that renders on the server side before being sent to the client (browser). At first glance, it may seem similar to Server Side Rendering (SSR) which has been used for a while, but in reality, these two concepts have certain differences. The Difference of RSC (React Server Component) Ease of development: React Server Component allows easy direct connection to server-side resources such as databases or internal services, streamlining development processes. Improved performance: By reducing latency in communication between client and server, React Server Component enhances overall application performance. Reduced source code size: Libraries utili...

Kubernetes Deployment for Zero Downtime

Image
Introduction In Kubernetes (K8s) , a Pod is the smallest resource unit used to run one or more containers during deployment. There are several ways to create a Pod : you can create it directly, use a ReplicationController , or a ReplicaSet . However, the most commonly used resource for managing Pods is the Deployment . When you use a Deployment , it actually creates a ReplicaSet to manage the Pods but comes with many additional benefits that support the deployment process. Some Advantages of Deployment : Ensures Pod Availability : It guarantees that the specified number of Pods are always running according to the configuration, automatically deploying additional Pods if any failures occur. Supports Restart and Undo Deployment : Allows you to easily restart or roll back to previous versions of your Deployment . Zero Downtime Deployment : When updating configurations or scaling Deployments , zero downtime is crucial. This means that new Pods are created while the old Pods are stil...

Deploying a NodeJS Server on Google Kubernetes Engine

Image
Introduction to GKE Google Kubernetes Engine (GKE) is a managed Kubernetes service provided by Google Cloud Platform , facilitating simple and efficient deployment of Docker images. We only need to provide some configuration for the number of nodes, machine types, and replicas to use. Some Concepts Cluster A Cluster is a collection of Nodes where Kubernetes can deploy applications. A cluster includes at least one Master Node and multiple Worker Nodes . The Master Node is used to manage the Worker Nodes . Node A Node is a server in the Kubernetes Cluster. Nodes can be physical servers or virtual machines. Each Node runs  Kubernetes , which is responsible for communication between the Master Node and Worker Node , as well as managing Pods and containers running on it. Pod A Pod is the smallest deployable unit in Kubernetes . Each Pod contains one or more containers, typically Docker containers. Containers in the same Pod share a network namespace, meaning they have the ...

Helm for beginer - Deploy nginx to Google Kubernetes Engine

Image
Introduction Helm is a package manager for Kubernetes , which simplifies the process of deploying and managing applications on Kubernetes clusters. Helm uses a packaging format called charts , which are collections of files that describe a related set of Kubernetes resources. Key Components of Helm Charts : Helm packages are called charts. A chart is a collection of files that describe a related set of Kubernetes resources. A single chart might be used to deploy something simple, like a memcached pod, or something complex, like a full web app stack with HTTP servers , databases, caches, and so on. Values : Charts can be customized with values, which are configuration settings that specify how the chart should be installed on the cluster. These values can be set in a ` values.yaml ` file or passed on the command line. Releases : When you install a chart, a new release is created. This means that one chart can be installed multiple times into the same cluster, and each can be indep...
