How To Dev

Introduction Google Cloud Pub/Sub is a fully-managed, real-time messaging service that enables you to send and receive messages between independent applications. This article will guide you through integrating NodeJS with Google Cloud Pub/Sub for simple message sending and receiving. Additionally, I've written an article on using Kafka , a distributed event streaming platform, to demonstrate message sending and receiving through NodeJS and Golang . Prerequisites Before proceeding with the following steps, make sure you have: A Google Cloud account with Pub/Sub enabled. Basic knowledge of NodeJS . In this article, I'm using a NodeJS TypeScript project. You can find setup instructions here . Implementing the Code After setting up your NodeJS TypeScript project , install the following package: yarn add @google-cloud/pubsub Next, update the ` main.ts ` file with the following content: import { PubSub , Topic , Subscription } from '@google-cloud/pubsub' export c...

Introduction Google Cloud Functions (GCF) is a component of Google Cloud Platform (GCP) that allows you to deploy functions in a simple and flexible way. With a serverless approach, you can focus on developing your product without spending much time and effort managing infrastructure or cloud storage. I previously wrote about deploying a NodeJS TypeScript application to Google App Engine . Now, let's explore how Google Cloud Functions can help you deploy the necessary functions on-demand. GCF supports multiple runtime environments such as NodeJS , Golang , Python , Ruby , Java , and .NET . You can create a Cloud Function directly through the Google Cloud Console or via the Google Cloud CLI . In this article, I'll guide you through using the Google Cloud CLI to deploy a Cloud Function developed with NodeJS and TypeScript. Prerequisites Before we proceed, make sure you have the following: A Google Cloud account with Cloud Functions enabled Basic knowledge of NodeJS . ...

Introduction Ansible is an open-source IT automation tool written in Python . It's widely used for configuration management, making complex tasks simpler by automating system setup, software deployment, and more. Ansible is agentless , meaning it doesn't require an agent to communicate with other machines. It supports a wide range of operating systems, platforms, and devices, from Ubuntu and VMware to CentOS , Windows , Azure , AWS , and network devices like Cisco and Juniper . This design increases Ansible's usability because you don't need to install and maintain agents on hosts. This is a significant advantage over similar tools like Chef , SaltStack , and Puppet . Why Choose Ansible? Here are some reasons to choose Ansible over other configuration management tools: Open Source : It's free to use. Uses SSH : Easily connects directly to servers. Lightweight : Easy to set up and doesn't consume many resources. Readable Syntax : Uses YAML for scripts, ma...

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 releases. Infrastructure as Code (IaC): This approach involves managing and provisioning computing infrastructure through machine-readable scripts, rather than physical hardware configuration. 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 impleme...

Introduction Google Cloud Platform (GCP) is a suite of cloud computing services provided by Google. It allows you to build, deploy, and scale applications, websites, and services on the same infrastructure that Google uses internally for its end-user products like Google Search, Gmail, and YouTube. Key Features of GCP Compute Services: Includes virtual machines (VMs) with Google Compute Engine, serverless computing with Google Cloud Functions, and container orchestration with Google Kubernetes Engine (GKE). Storage and Databases: Offers various storage options like Google Cloud Storage for object storage, Google Cloud SQL for managed relational databases, and Google Bigtable for NoSQL databases. Networking: Provides a global network infrastructure with services like Virtual Private Cloud (VPC), Cloud Load Balancing, and Cloud CDN for content delivery. Big Data and Machine Learning: Includes tools like BigQuery for data warehousing, Dataflow for stream and batch data processing, and AI ...
