AWS EC2: Elastic Compute Cloud Overview

Amazon Elastic Compute Cloud (EC2) is a cloud-based service provided by AWS that delivers resizable computing power. It allows users to run virtual servers (instances) with customizable configurations. EC2 simplifies scaling operations, enabling you to adjust resources as your computing requirements change.

Benefits of Using AWS EC2

Simplified Maintenance: AWS manages updates, patches, and other backend server tasks.
Cost Efficiency: Pay only for the computing resources you use, saving operational costs.
Flexibility: Choose from a variety of operating systems, configurations, and instance types.

Categories of EC2 Instances

AWS EC2 offers multiple types of instances to meet diverse computing needs:

General-purpose Instances: Perfect for applications requiring balanced performance in memory, storage, and compute power. Example use case: email servers.
Compute-optimized Instances: Ideal for CPU-intensive workloads, such as real-time data analysis.
Memory-optimized Instances: Best suited for tasks demanding significant RAM, such as large-scale in-memory databases.
Storage-optimized Instances: Designed for applications that handle vast datasets or require substantial storage.
GPU Instances: Tailored for graphics-heavy applications like 3D modeling and rendering.

Each instance type has specialized configurations optimized for specific tasks, ensuring efficient resource utilization.

Steps to Launch an EC2 Instance

Follow these steps to set up an EC2 instance in AWS:

Log in: Access the AWS Management Console.
Select a Region: Choose the AWS region closest to your operational base.
Access EC2: From the dashboard, navigate to EC2 and click "Launch Instance."
Choose AMI: Select an Amazon Machine Image (AMI), such as Ubuntu, Windows Server, or others based on your requirements.
Select Instance Type: Pick the instance type (e.g., t2.micro for free-tier eligibility).
Configure Instance: Specify details like network, subnet, and instance count.
Allocate Storage: Define storage capacity (e.g., 8 GiB for a test instance).
Add Tags: Assign tags for easy identification and management.
Set Security Rules: Create a security group to control instance access.
Review and Launch: Verify configurations and generate a key pair for secure login.

Connecting to an Instance Using PuTTY

To access your EC2 instance using PuTTY:

Convert Key Format: Use PuTTYgen to change your PEM key file into PPK format.
Configure PuTTY:

Enter the instance's public IP in the hostname field.
Load the PPK file under the SSH authentication section.

Log In: Open the connection, entering the default username (e.g., ubuntu for Ubuntu).

Congratulations! Your instance is now up and running.
