Continuous Integration (CI) and Continuous Deployment (CD) are essential practices in modern software development. CI ensures that code changes are automatically tested and integrated into a shared repository, while CD automates the deployment process. Together, they help teams deliver software faster, with fewer errors and a higher level of consistency. What is the difference between Docker and Kubernetes?

1. What is Amazon EC2? Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. 2. What are the different types of EC2 instances? EC2 instances are categorized into different families based on their intended use case. The main categories are 1 .      General Purpose (e.g., t3, t3a, m5, m5a),    Compute Optimized (e.g., c5, c5n),    Memory Optimized (e.g., r5, r5a),   Storage Optimized (e.g., i3, d2), and   Accelerated Computing (e.g., p3, g4). 3. What is the difference between stopping and terminating an EC2 instance? When you stop an instance, it shuts down and you can restart it later, preserving all data on the instance store and EBS volumes. When you terminate an instance, it is permanently deleted, and you lose all data stored on the instance store. EBS volumes can be retained depending on thei...
