Step-by-Step: Mount EFS on EC2.
Introduction. Amazon Elastic File System (EFS) is a scalable and fully managed network file system that allows multiple EC2 instances to access shared storage simultaneously. It is designed to provide elastic capacity, meaning it can automatically grow and shrink as you add or remove files, eliminating the need to provision storage in advance. Mounting EFS […]

From Zero to Ansible: Installing & Connecting Two Servers Easily.
Introduction. Managing servers manually can be time-consuming, repetitive, and prone to human error. Imagine having multiple servers and needing to install software, update packages, or configure services on each of them one by one. It’s not only tedious but also increases the risk of mistakes. This is where automation tools like Ansible come in, saving […]
Deploying a Simple SQLite App on Kubernetes with Persistent Storage (PVC).
Introduction: This project demonstrates how to run a simple SQLite-based Python application on Kubernetes using a PersistentVolumeClaim (PVC). In real-world applications, data must not be lost when a pod stops, restarts, or gets recreated. Kubernetes solves this problem using persistent storage. SQLite stores data inside a single file (mydb.sqlite). If the pod restarts without persistent storage, this […]
