Step-by-Step Guide: Deploying an Application on AWS using DevOps

Step 1: Create an AWS Account

To use AWS services, you need to have an AWS account. Go to the AWS website (https://aws.amazon.com/) and click on the “Create an AWS Account” button. Follow the instructions to create an account.

Step 2: Set up the IAM User

IAM (Identity and Access Management) allows you to manage access to your AWS resources. It is recommended to create a separate IAM user for your DevOps tasks.

To create an IAM user, go to the IAM console: (https://console.aws.amazon.com/iam/) and click on “Users” in the left navigation menu. Click on “Add user” and follow the instructions to create a new user with appropriate permissions.

Step 3: Set up AWS CLI

AWS Command Line Interface (CLI) allows you to interact with AWS services using commands in your terminal. Install AWS CLI on your local machine and configure it with the IAM user’s credentials created in the previous step.

Step 4: Set up CodeCommit Repository

CodeCommit is a source control service in AWS that allows you to store and manage your code repositories. Create a new CodeCommit repository to store your application code.

Step 5: Set up the CodeBuild Project

CodeBuild is a fully managed build service in AWS. It can be integrated with CodeCommit to automatically trigger builds whenever there is a change in the code. Create a new CodeBuild project and configure it to use your CodeCommit repository as the source. You can also specify build commands, environment variables, and other configurations.

Step 6: Set up S3 Bucket

S3 (Simple Storage Service) is an object storage service in AWS. Create an S3 bucket to store your application files and artifacts.

Step 7: Build and Package your Application

Write your application code and commit it to the CodeCommit repository. This will trigger a build in CodeBuild, where your code will be compiled, tested, and packaged into an artifact.

The artifact can then be uploaded to your S3 bucket for further deployment.

Step 8: Set up an EC2 Instance

EC2 (Elastic Compute Cloud) allows you to deploy and manage virtual servers in the cloud. Launch an EC2 instance with your preferred operating system and configuration.

Step 9: Install and Configure Deployment Tools

Install any necessary deployment tools and configure them to work with your EC2 instance. This could include tools like HTTP servers, application servers, or databases.

Step 10: Deploy the Application using Elastic Beanstalk

Elastic Beanstalk is a service in AWS that allows you to easily deploy and scale web applications. Create an Elastic Beanstalk environment and configure it to use your EC2 instance as the underlying infrastructure.

You can also specify deployment settings, environment variables, and other configurations, and then deploy your application from the S3 bucket where the artifact was stored.

Step 11: Test and Monitor the Application

Run tests on the deployed application to ensure everything is functioning as expected. Use AWS services like CloudWatch to monitor your application’s performance and detect any potential issues.

Step 12: Continuous Integration and Delivery

To automate the deployment process, you can set up continuous integration and delivery (CI/CD) pipelines using AWS services like CodePipeline and CodeDeploy. This will enable you to automatically trigger builds and deployments whenever there is a new code change, ensuring a faster and more efficient deployment process.
