Kube8Cloud Solution:
Kube8Cloud & Ambition hire had several brain stroming sessions and deepdive sessions to understand As-Is application Architecture. We have agreed to host the microservices in AWS ECS, as it is quick to adopt. ECS provides native integration with AWS Services and easy to implement IAM Policies for RBAC. AWS RDS Aurora for MySQL was used for the Database. The high level architecture and implementation is as follows:
- Create VPC for all the AWS Resources
- Create ECS Cluster
- Define Tasks for each Microservices
- Enable CloudWatch Monitoring
- Create Amazon RDS Aurora Database
- Configured Multi-AZ for High Availability
- Encrypted Data at Rest using AWS CMK
- Encrypted Data in Transit by using SSL
- Create Jenkins for DevOps
- Create CI/CD DevOps Pipeline
- Migrated using Backup and Restore Approach
- Enabled Automated Snapshots with 15 days retention
- Chosen Maintenance Window for automated Patching and upgrades
Business Impact:
- Highly Scalable front-end & back-end
- Enhanced Database Security
