When Kubernetes breaks in production, you need practical solutions, not theory. After years of firefighting Kubernetes issues across various environments, I’ve compiled these 10 real-world troubleshooting scenarios you’re likely to encounter. Each includes the exact commands and steps to diagnose…
When anyone talks about DevOps, CICD is the first word that comes to mind. CICD stands for Continuous Integration and Continuous Deployment (or Delivery). It’s like having a super-efficient assembly line for your software just like car manufacturers have been…
Docker revolutionized how we run applications by packing the application with the platform dependencies as containers. While Docker is great for individual containers, real-world applications often require multiple containers working together, such as a web server, a database, and an…
If you are new to using Terraform on AWS, then this blog post will show you how to use Terraform to deploy a 3-tier architecture. Scenario: A three–tier architecture on AWS Creating a three–tier architecture on AWS involves setting up three…
Accessing Amazon S3 privately enhances security, improves performance, reduces costs, ensures compliance with regulatory requirements, simplifies network architecture, and provides reliable and managed connectivity. This approach is particularly beneficial for workloads that require secure, high-performance, and cost-effective access to S3.…

Terraform stands out as a powerful tool for managing and provisioning cloud resources. However, as your infrastructure grows more complex, you might find yourself repeating code blocks, leading to verbose and hard-to-maintain configurations. To address this, Terraform offers a dynamic…
When I first started with Terraform to write configuration to deploy infrastructure on AWS and GCP, I did not know how powerful Terraform is. I wrote configuration code like an armature — repeated code blocks, hardcoded values, and bloated and inflexible infrastructure…
When I first started writing Terraform, I was terrible at it. I found myself drowning in a sea of repetitive blocks, each stuffed with hardcoded values. A simple change required me to update my code at multiple places, and the…
Terraform is the most popular and widely used Infrastructure as a code tool out there, irrespective of the cloud platform. It has become the synonym for IAC. All credit goes to Hashicorp people who saw a need to have a…
If you go back two decades, everyone used those physical servers (produced by IBM, HP, and Cisco) which took weeks to setup correctly before we could run the applications on them. Then came the time of virtualization, Sharing computing resources…
