Week 7 Achievements

Containerization & Orchestration

  • Successfully “dockerized” a monolithic application, decoupling it from the underlying infrastructure.
  • Deployed a highly available container cluster using Amazon ECS, utilizing Task Definitions to define resource requirements.
  • Configured Service Discovery to allow microservices within the cluster to communicate via logical names instead of IP addresses.
  • Implemented Application Load Balancer to distribute public traffic to dynamic container targets.

DevOps & CI/CD Automation

  • Built a robust CI/CD Pipeline using AWS CodePipeline and CodeBuild.
  • Achieved Continuous Deployment: Code changes pushed to the repository automatically trigger a build, image creation, and rolling update to the ECS service without downtime.
  • Integrated comprehensive monitoring using CloudWatch Container Insights to track CPU/Memory utilization of tasks.
  • Centralized container logs using FireLens for easier debugging and analysis.

Hybrid Storage Implementation

  • Bridged the gap between on-premises protocols and cloud storage.
  • Configured File Storage Gateway to allow legacy applications to write to S3 using standard NFS protocols.
  • Deployed Amazon FSx for Windows File Server, providing a fully managed, native Windows file system with Active Directory integration.

High-Performance Database Design

  • Mastered NoSQL concepts with Amazon DynamoDB.
  • Optimized database performance by designing efficient Partition and Sort Keys.
  • Implemented Global Secondary Indexes (GSI) to support diverse access patterns without duplicating data tables.
  • Explored DynamoDB Streams for event-driven architectures (triggering Lambda functions on database changes).
