Amazon EC2 Case Study

Amazon EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud. It allows users to run virtual servers, known as instances, on-demand, making it easier to deploy and manage applications.

Key Features:

• Scalability
• Variety of instance types
• Integration with other AWS services
• Pay-as-you-go pricing

This case study focuses on deploying a simple web application using EC2 instances.

Scenario

Imagine a startup that needs to host a new web application for its users. The team decides to use EC2 for its flexibility and cost-effectiveness.

Requirements

• Ability to handle up to 1000 users concurrently
• High availability
• Automatic scaling based on traffic

The following steps outline how to deploy the web application on EC2:

1. Set up an AWS account and log in to the AWS Management Console.
2. Create an EC2 instance:

   aws ec2 run-instances --image-id ami-12345678 --count 1 --instance-type t2.micro --key-name MyKeyPair

3. Configure security groups to allow HTTP and SSH access.
4. Deploy the web application code to the EC2 instance.
5. Set up an Elastic Load Balancer (ELB) to distribute traffic.
6. Implement Auto Scaling to manage instance count based on load.

To ensure efficient and secure usage of EC2, consider the following best practices:

• Use IAM roles for EC2 instances to grant permissions securely.
• Regularly update and patch your instances.
• Monitor your instances using CloudWatch.
• Utilize spot instances for cost savings when appropriate.
