Problem - Issues with Current Situation:

• In an Agile SDLC, there will be Frequent Code Changes

• Manual Code Deployment is Time Consuming

• Developer and Testers not equipped with Ops Knowledge

• Need to Hire Ops Professionals

• Or Outsource

• Dependency on Ops Team

• CI/CD Server Maintenance

• Operational Overhead to Maintain Servers like Jenkins, Nexus, Sonar, Git, QA Server for Testing

Solution - Fix:

• PaaS (Platform as a Service) and SaaS (Software as a Service) Cloud Services

• Disposable Environment

• Automate Cl/CD Process

• Build, Test, Deploy and Test for Every Commit

Benefits - CI/CD Pipeline on Cloud:

• Short MTTR (Mean Time to Recovery)

• No Human Intervention

• Fault Isolation

• Agile

• No Ops

AWS Services and Tools used in the Project:

• AWS CodeCommit - Version Control System

• AWS CodeArtifact - Maven Repository for Dependencies

• AWS CodeBuild - Build Service from AWS

• AWS CodeDeploy - Artifact Deployment Service

• AWS CodePipeline - Service to Integrate all Jobs Together

• Amazon S3 - Artifact Deployment

• AWS Systems Manager Parameter Store - Hierarchical Parameters Storage

• SonarCloud - SonarQube Cloud based Tool

• Checkstyle - Code Analysis from Build Job

• Selenium (Software Testing) - Code Build and Others

• AWS Elastic Beanstalk - For Hosting Application

• Amazon RDS - Database for Application Service

• Amazon SNS - Notification Service from AWS
