Let’s Get Terraform Ready, Infra Coders! Hey there, Infra coders! In our last discussion, we learned what Terraform is and why it’s your go-to tool for building infrastructure with code. Now, it’s time to roll up our sleeves and set it up on your computer. Don’t worry—this is easier than it sounds! By the end of this article, you’ll have Terraform installed, configured, and ready to create your first cloud resources. Think of this as setting up your toolbox before building something awesome. We’ll cover installing Terraform, setting up a cloud provider (like AWS), and writing a simple configuration file…

What is Terraform? Let’s Start Simple Hey there, Infra coders! Imagine you’re building a house, but instead of hammering nails and laying bricks by hand, you write a blueprint that magically builds the house for you. That’s kind of what Terraform does for tech stuff like servers, databases, and networks. Terraform is a tool that lets you write code to create and manage your infrastructure—the servers, storage, and other tech resources you need for your apps. This idea is called Infrastructure as Code (IaC), and it’s a game-changer! With Terraform, you don’t need to click around in a web console…

Hey there! Managing Kubernetes clusters can be tough, right? You’ve got so many YAML files, deployments, and changes to track. What if I told you there’s a smarter way to handle all this using GitOps? With GitOps, we use Git as the single source of truth for all our Kubernetes configurations. And ArgoCD is a super cool tool that makes this happen. In this article, I’ll walk you through how to set up a GitOps workflow with Kubernetes and ArgoCD in a simple, step-by-step way. Let’s make your life easier! What is GitOps and Why ArgoCD? GitOps is a way…

What’s an IP Address? Before we jump in, let’s quickly understand what an IP address is. It’s a unique number that identifies your device—like your phone, laptop, or router—on the internet. For example, when you watch a YouTube video, your device uses its IP address to tell YouTube, “Hey, send that video to me!” There are two types: public (used on the internet) and private (used inside your home network). Okay, ab let’s find it! For more details about IP address visit What Is an IP Address? A Beginner’s Guide How to Find Your IP Address Finding your IP address…

Kubernetes is a big deal for managing apps in containers, and if you’re new to it, you might get asked some basic questions in interviews. No stress! This article has 15 common Kubernetes questions for beginners, with answers written like you’d say them in an interview. I’ve added examples and images where they help. Let’s get started! 1. What is Kubernetes? Candidate Reply: Kubernetes is a tool that helps manage containerized apps, like those running in Docker. It makes sure your apps are running smoothly across many servers, handling things like scaling, updates, and restarts automatically. 2. Why do we…

Hey there! If you’ve ever heard about databases and wondered what the deal is with NewSQL, you’re in the right place. I’m going to break it down for you, like we’re chatting over coffee. NewSQL is a cool new type of database that tries to take the best parts of traditional SQL databases (like MySQL) and NoSQL databases (like MongoDB) and mash them together. Let’s dive in and see what it’s all about. What’s NewSQL Anyway? Imagine you’re running an online store. You need a database to keep track of customers, orders, and products. A traditional SQL database, like MySQL…

Terraform interviews often include scenario-based questions to test how you solve real-world problems. These questions check your practical knowledge and decision-making. This article covers 10 common scenarios with answers written like you’d say them in an interview. Let’s jump in! 1. Your team accidentally deleted the Terraform state file. What do you do? Candidate Reply: Losing the state file is bad because Terraform won’t know what resources it’s managing. First, I’d check if we have a backup, like in an S3 bucket if we’re using a remote backend. If there’s no backup, I’d use `terraform import` to rebuild the state…

If you’re aiming for a senior DevOps or cloud architect role, you’ll likely face some tough Terraform questions. This article covers 25 advanced questions with answers written like you’d explain them in an interview. I’ve added code snippets and examples where they help. Let’s get started! 1. How do you secure a Terraform state file? Candidate Reply: Securing the state file is super important because it contains sensitive info like resource IDs or passwords. I use a remote backend like AWS S3 with encryption enabled and lock it with DynamoDB to prevent conflicts. I also restrict access using IAM policies…

Terraform is a super popular tool for managing infrastructure as code, and if you’re starting out, you might get asked some basic questions in interviews. Don’t worry! This article covers 25 common Terraform questions for beginners, with answers written like how you’d actually reply in an interview. Let’s dive in! 1. What is Terraform? Candidate Reply: Terraform is a tool by HashiCorp that lets you create and manage infrastructure using code. Instead of manually setting up servers or databases, you write code to describe what you need, and Terraform makes it happen on cloud platforms like AWS, Azure, or Google…

What’s an IP Address? Imagine the internet is like a huge city, and every device—your phone, laptop, or even your smart TV—is like a house in that city. Now, just like every house has a unique address (like “123, Main Road, Delhi”), every device on the internet has a unique address too. This address is called an IP address. IP stands for Internet Protocol. It’s like a rulebook that helps devices talk to each other. The IP address is a special number that identifies your device so it can send and receive data—like emails, videos, or WhatsApp messages. For example,…
