Introduction Deploying monolithic applications like WordPress into microservice architectures requires robust container orchestration to achieve enterprise-grade availability, auto-scaling, and failover support. While traditional single-server installations introduce single points of failure, containerizing WordPress with Docker, hosting images in Amazon Elastic Container Registry (ECR), and orchestrating worker nodes via Amazon Elastic Kubernetes Service (EKS) delivers a fault-tolerant…

If you are planning to work with AWS services from your computer, one essential tool you will need is the AWS Command Line Interface (CLI). It lets you manage AWS services right from your terminal or command prompt. In this post, I will guide you through installing AWS CLI and setting it up so you…

Manually launching an EC2 instance from the AWS console can be time-consuming especially if you need to do it again and again. That is where Terraform comes in. It helps you automate the process so you can launch EC2 instances quickly, with just a few commands. In this blog, I will show you step-by-step how…

Introduction In modern multi-tenant cloud architectures, organizations frequently isolate environments across distinct AWS accounts for security boundaries. For example, building Docker images in a primary Development account (Account A) and deploying them into a Production environment (Account B) requires secure, cross-account container distribution. Amazon Elastic Container Registry (ECR) supports granular IAM resource policies to share…

Introduction The operating system you choose directly impacts your daily productivity. It affects your workflow and system stability. Today, one operating system quietly runs the modern digital world: Linux. In this guide, we will explore the core Linux architecture. We will compare Linux with Windows and macOS. we will cover popular Linux distributions for developers…

Introduction As organizations migrate their workloads to the cloud, securing cloud infrastructure becomes a top priority. In Amazon Web Services (AWS), Identity and Access Management (IAM) is the foundation of cloud security. In this tutorial, we will explain the core concepts of AWS IAM and demonstrate step-by-step how to restrict user access to specific EC2…

Introduction Modern cloud architectures require strict network isolation to safeguard sensitive databases and application workloads from unauthorized access. Amazon Web Services provides this network layer through Amazon Virtual Private Cloud (AWS VPC). In this tutorial, we will explain the fundamental components of an AWS VPC and demonstrate step-by-step how to build a multi-AZ custom network…

In today’s digital economy, managing physical server infrastructure on-site can be costly and inefficient. Organizations worldwide rely on cloud platforms to deploy applications faster, lower capital costs, and scale seamlessly. In this beginner-friendly guide, we will break down the core fundamentals of cloud computing, compare different cloud deployment models, and introduce the key services offered…

Introduction In modern enterprise cloud environments, application downtime leads directly to lost revenue and poor user experience. Designing a High Availability (HA) architecture ensures your applications remain resilient, performant, and operational even during server failures or sudden traffic surges. In this step-by-step tutorial, we will construct a fault-tolerant, highly available architecture on AWS. We will…

Introduction Containerization has revolutionized modern software development by enabling developers to package applications with all their dependencies. Docker simplifies application deployment, making software consistent across development, testing, and production environments. In this step-by-step tutorial, we will demonstrate how to install Docker on an AWS EC2 instance and run an Nginx web server inside a Docker…
