DevOps Practice Series

Introduction

DevOps is a combination of development (Dev) and operations (Ops), aimed at uniting people, processes, and technology to enhance the software development lifecycle. Here are some key aspects of DevOps:

  • Collaboration and Communication: DevOps fosters a culture where development, IT operations, quality engineering, and security teams work together seamlessly.
  • Continuous Integration and Continuous Delivery (CI/CD): These practices automate the integration and delivery of code changes, ensuring faster and more reliable software releases¹.
  • Infrastructure as Code (IaC): This approach involves managing and provisioning computing infrastructure through machine-readable scripts, rather than physical hardware configuration¹.
  • Monitoring and Logging: Continuous monitoring and logging help teams to detect issues early and maintain system reliability.
  • Automation: Automating repetitive tasks reduces errors and increases efficiency, allowing teams to focus on more strategic work.

By implementing DevOps practices, organizations can achieve faster time-to-market, improved product quality, and better alignment with customer needs.

Here are some technologies related to DevOps that I will present in this series:

  • Shell script
  • Docker
  • Kubernetes (K8s)
  • Terraform
  • CI/CD: Gitlab, Github, Jenkin
  • Cloud Platform: Google Cloud Platform, Amazon Web Service, Azure Web Service
  • Monitor: cAdvisor, Prometheus, Grafana, Elastic Stack (ELK - Elasticsearch, Kibana & Logstash)

I will continue to update more posts in the future to make the series more complete as new ideas for articles come to mind. The order of the articles has been arranged by increasing difficulty, making it easier for you to follow. So, if you have the time, I recommend starting the series from the beginning to ensure you grasp the necessary knowledge and information needed for the upcoming posts.

  1. Docker
  2. Kubernetes
  3. Google Cloud Platform
  4. CI/CD
    1. Setup Gitlab CI
    2. Github CI/CD with Google Cloud Build
  5. Monitor
    1. Monitoring with cAdvisor, Prometheus and Grafana on Docker

NodeJS Practice Series

Image
Introduction NodeJS is an open-source and cross-platform JavaScript runtime environment . Here are some key points about NodeJS : V8 Engine : NodeJS runs on the V8 JavaScript engine , which is also the core of Google Chrome . This allows NodeJS to be highly performant. Asynchronous and Non-Blocking : NodeJS  uses an event-driven, non-blocking I/O model. It’s lightweight and efficient, making it ideal for data-intensive real-time applications. Single-Threaded : NodeJS  runs in a single process, handling multiple requests without creating new threads. It eliminates waiting and continues with the next request. Common Language : Frontend developers who write JavaScript for browsers can use the same language for server-side code in NodeJS . You can even use the latest ECMAScript standards without waiting for browser updates. This page is designed to compile articles related to NodeJS , including how to integrate it with various libraries and relevant tech stacks. I will continue to u

Explaining Async/Await in JavaScript in 10 Minutes

Image
Introduction For a long time, we've relied on callbacks to deal with asynchronous code in JavaScript. As a result, many of us have faced dreadful experiences dealing with deeply nested functions ( callback hell ). Callback hell Callbacks come with a lot of drawbacks. When we have multiple asynchronous operations, callbacks have to wait for each other to execute, prolonging the completion time. Additionally, writing nested callbacks makes our code messy and hard to maintain. In the ES6 (ECMAScript 2015) version, JavaScript introduced Promises. This was a fantastic replacement for callbacks and was quickly embraced by the community. Our new code looks similar to the old one, making it easier to follow and maintain. However, the issues with callbacks weren't completely resolved. Since the ES7 (ECMAScript 2016) version, Async/Await has been added to make asynchronous code in JavaScript look and feel easier to use. What is Async/Await? Async/Await is a feature of JavaScript that

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 same

What is react-query? Why should we use react-query?

Image
Introduction You might have heard or seen others mention the react-query library quite often. Why should we use react-query when we can use useEffect to fetch data from an API ? This article will answer that question. What is react-query? react-query is a set of hooks for fetching, caching, and updating asynchronous data in React . Simply put, react-query is a library for fetching , caching , and updating asynchronous data when used in React . Why should we use react-query? Normally, there are many ways to fetch data from a server. Some popular methods include using useEffect and useState , or using a state management library like redux . export const Page = () => { const [ data , setData ] = useState (); useEffect (() => { const loadData = async () => { const response = await fetch ( hostAPI ). then ( response => response . json ()); setData ( response ) } loadData () }) return < DisplayData /> } This me

A Handy Guide to Using Dynamic Import in JavaScript

Image
Introduction In JavaScript, when we import a file, the process usually happens synchronously, known as static import. However, as our applications grow, this synchronous loading can lead to slower initial page loads due to larger JavaScript bundles. Moreover, there are times when imports are necessary only under specific circumstances, leading to unnecessary loading times for users who might not even utilize those features. Details Instead of burdening all users with unnecessary imports, dynamic imports come to the rescue. They allow us to load modules or files only when they are needed, thus improving performance and user experience. Dynamic imports are invoked using the import() function and return a promise. When using default exports, the exported data can be accessed through the default field, while other data can be accessed through fields with matching names. Here's how you can use dynamic imports: import ( "ramda" ). then ( module => { const moduleDefaul

Create API Gateway with fast-gateway

Image
Introduction In this article, I will guide you on how to use fast-gateway to deploy a simple API Gateway on NodeJS along with express . The advantage of an API Gateway is that it acts as an intermediary layer to hide the rest of the system, including services, commonly used in Microservices architecture. Example Usage This is the Microservices model after deployment: First, install the package yarn add fast-gateway Next, define the ports that will be used. import * as express from 'express' import * as gateway from 'fast-gateway' const portGateway = 5000 const portService1 = 5001 const portService2 = 5002 Define service 1 as follows: const startService1 = (): void => { const app = express () app . get ( '/list' , ( req , res ) => { const items = [ { id: 1 , name: 'service 1 value 1' , }, { id: 2 , name: 'service 1 value 2' , }, ] re
