AWS Web Application CI/CD Pipeline

Challenge

Manual deployment processes are time-consuming, error-prone, and difficult to scale. The objective was to design a streamlined workflow to automatically build and deploy application updates.

Solution

Implemented a continuous integration and continuous deployment (CI/CD) pipeline that automates the process of building and deploying a web application to AWS. Each code change pushed to the repository triggers an automated workflow, ensuring consistent and efficient delivery of updates.

Key Components:

• Infrastructure as Code (AWS CloudFormation): Automated provisioning of VPC, Security Groups, and EC2 instances to ensure consistent and repeatable environment setup.
• Orchestration (AWS CodePipeline): Managed the end-to-end CI/CD workflow, coordinating source, build, and deployment stages across services.
• Continuous Integration (AWS CodeBuild): Compiled and packaged the application using a buildspec.yml, producing a deployable .war artifact.
• Continuous Deployment (AWS CodeDeploy): Executed in-place deployments on EC2 instances using an appspec.yml and custom Bash scripts.
• Web Architecture (Apache & Tomcat): Configured Apache as a reverse proxy to handle incoming HTTP requests and forward them to the Tomcat application server.
