What is AWS EC2?

EC2 stands for Elastic Cloud Computing, a service provided by Amazon Web Services. With EC2, you can rent virtual machines (VMs) in the cloud, avoiding the need to invest in expensive physical servers. EC2 instances can be customized according to your needs, including CPU, RAM, and storage configurations.

Benefits of Using AWS EC2

  • Cost-effective: You only pay for the hours you use the instance, making it a cost-efficient option.
  • Flexible: You can easily scale your resources up or down by adjusting the instance specifications.
  • Secure: AWS provides features like Virtual Private Cloud (VPC) and Security Groups to ensure the security of your instances.
  • Easy to use: With a user-friendly interface, you can create and manage instances with just a few clicks.

Step-by-Step Guide to Deploying Your Application on AWS EC2

Step 1: Create a VPC and Configure Security Groups

Before creating an EC2 instance, you need to set up a Virtual Private Cloud (VPC) and configure your security groups. A VPC acts as a network for your instances, allowing you to control access and set up network settings. Security Groups, on the other hand, filter incoming and outgoing requests to your instances.

Step 2: Create an EC2 Instance

  1. Choose your region and launch a new instance.
  2. Name your instance and select the operating system (OS) (e.g., choose the default Amazon Linux if you prefer a Linux distribution).
  3. Specify the instance size based on your needs and budget.
  4. Configure networking settings, ensuring that you choose a public subnet to allow outside access.
  5. Assign a public IP to your instance for external access.
  6. Select the appropriate security group that you configured earlier.
  7. Leave the storage settings as default.
  8. Launch the instance and wait for it to become available.

Step 3: Connect to Your EC2 Instance

  1. Retrieve the public IP address of your instance.
  2. Use SSH to connect to your instance using the default user “ec2-user”.
  3. Once connected, you can install any necessary dependencies, such as Java, for your application.

Step 4: Deploy Your Application to the EC2 Instance

  1. Compile and package your application.
  2. Upload the package to AWS S3, a simple storage service that allows you to store and retrieve files.
  3. Configure a startup script in the EC2 instance to download and run the latest version of your application from S3.

Step 5: Automate Your Deployment with CI/CD

To automate the deployment process, integrate your CI/CD pipeline with AWS EC2. Here’s how:

  1. Create an Amazon Machine Image (AMI) from your EC2 instance, which will serve as a backup of your instance’s content.
  2. Use the user data script, which runs at startup, to download the latest version of your application from S3 and start it.
  3. After testing and packaging your application in the pipeline, upload the package to S3 and start a new EC2 instance from the AMI.


AWS EC2 provides a reliable and scalable infrastructure for deploying your applications. By following these steps, you can easily set up your EC2 instance, deploy your application, and even automate the process through a CI/CD pipeline.
