The Solution Offered

Description of the detailed solution provided as below:

According to the requirements we have used 3 approaches for hosting the projects using Automation and DevOps features offered by AWS.
To avoid manual hosting of the servers for project 1 and 2 we offered them two different pipelines. AWS CodeDeploy was used in project 2 and AWS ECS for project 1. Both ensured that the projects were deployed with the ability to scale and remain highly available throughout the load variations by setting required Auto Scaling Groups and Load balancers.

We offered to re-architect the project2 entirely due lack of availability and consequently difficulties in updating the app with new features. New AWS Code Pipeline was implemented to automate the deployment process. AWS CodeCommit was used for source control, AWS CodeBuild was used to build the code and perform some testing, and as previously mentioned AWS CodeDeploy was used as for auto-deployment. Database was migrated from EC2 server to RDS.
For Project1 we suggested and implemented AWS ECR and ECS service and to automate the deployment and testing we have created Code Pipeline using Code Commit, CodeBuild service.

We offered AWS Patch Manager for scheduled patching of the AWS EC2 instances. As per their organisational requirements, the instances had to be patched for every 3 months. It also collected data related to any vulnerabilities and errors in patches.
For Disaster recovery of the current infrastructure, we have configured EDR service in Singapore region with RPO as 1-2 Min and RTO as 15-20 Min.
Customer wanted to deploy Project3 on AWS using AWS Beanstalk and integrated with RDS for MySQL. Customer didn’t require automation for this project.

The Benefits:

• By implementing Code Pipeline, we were able to automate the release process and reduce deployment time, and Autoscaling improved the scalability and high availability of applications.
• Re-architecting project2 helped the developers to update the application with different features without having to introduce recurring down times as the new architecture ensured that application was high available and since the building, testing and deployment was automated, time-to-market of all the updates was significantly reduced.
• We have implemented AWS ECS service for containerized application and to automate the deployment we used AWS Code Pipeline which improved the scaling and high availability of application.
• Due to the implementation of CloudFront and WAF resolves the latency and mitigate the unauthorized traffic which improves the security of application.
• Due to the use of Code Build service, build time was reduced and the setup of an on-prem build server was eliminated.
• In order to avoid the issues that occur while manually managing the patches of EC2 instances SSM Patch manager was utilized.
