Goal: Move from “Cloud-Enabled Developer” → Cloud Solutions Architect for Enterprise & Government Systems

Cloud-Native Development is the stage where you build, deploy, and operate microservices the way cloud platforms expect—scalable, resilient, secure, and observable.
This phase converts your TPI Modernization Journey into a fully cloud-ready implementation.

🎯 Objective

Learn to design & build cloud-optimized microservices leveraging containerization, orchestration, and modern DevOps pipelines.

📌 Key Concepts You Will Master

1. 12-Factor App Methodology

Build services that are:

  • Stateless
  • Config-driven
  • Portable
  • DevOps ready
    Perfect for GovTech + Enterprise microservices.

2. Containerization → Docker

  • Create lightweight container images
  • Build secure Dockerfiles
  • Multi-stage builds for production
  • Push images to ECR / ACR / GCR

3. Orchestration → Kubernetes (EKS / AKS / GKE)

Master:

  • Deployments, StatefulSets, DaemonSets
  • Ingress & Service Types
  • Autoscaling (HPA/VPA)
  • Cloud-native logging & monitoring
  • Rolling updates & zero-downtime releases

4. Service Mesh → Istio / Linkerd

Enhance cloud microservices with:

  • mTLS security
  • Traffic routing & A/B testing
  • Observability dashboards
  • Policy enforcement

5. Cloud Config Management

Use:

  • AWS Systems Manager Parameter Store
  • AWS Secrets Manager
    For secure app configuration & credential rotation.

6. API Gateway & Load Balancing

Implement:

  • ALB / NLB
  • AWS API Gateway
  • Rate limiting & throttling
  • Gateway routing for microservices

7. CI/CD Pipelines

End-to-end modern delivery pipeline:

  • Jenkins (Gov Infra / On-Prem)
  • GitHub Actions
  • AWS CodePipeline + CodeBuild
  • Image scanning + security scans
  • Automated rollout to EKS
