Cloud Architecture Showcase

A portfolio-friendly collection of cloud architecture case studies and diagrams. Each case study is a production‑minded design with rationale, security posture, and CI/CD strategy, written in a concise, engineering‑report style.

• Focus: High‑performance, horizontally scalable, resilient systems with strong observability
• Vendors: Starts with AWS; more providers may be added over time

---

Highlights

• Case Study 1 – AWS Microservices (ECS on Fargate)
  • Route 53 → CloudFront → ALB (TLS termination, path‑based routing)
  • Microservices on ECS Fargate (User, Payment, Notification)
  • Polyglot persistence: Aurora (relational), DynamoDB (NoSQL) + ElastiCache
  • Async decoupling via SQS; observability via CloudWatch
  • CI/CD: CodeCommit → CodePipeline → CodeBuild → ECR → ECS

Preview:

• Read the full write‑up: Arsitektur-Microservices/README.md
• Diagram source: Arsitektur-Microservices/Arsitektur-Microservices.drawio.png (created with diagrams.net/draw.io)

---

• Case Study 2 – Retrieval‑Augmented Generation (RAG) on AWS (Vendor‑Agnostic)
  • Ingestion from internal stores (S3/GCS/Azure Blob)
  • Preprocessing & chunking → embeddings → vector database (OpenSearch Vector/Qdrant/Weaviate/Redis Vector)
  • RAG orchestration with LangChain/Haystack; LLM endpoint (SageMaker/Bedrock or OSS self‑hosted)
  • API Gateway front door; ECS Fargate services; CloudWatch observability
  • CI/CD: CodeCommit → CodePipeline → CodeBuild → ECR → ECS; model/prompt versioning

Preview:

• Read the full write‑up: RAG/README.md
• Diagram source: RAG/RAG.drawio.png

How to Use

• Browse: Open each case study’s README.md for the narrative, diagrams, and rationale
• Reuse: Copy architecture sections (components, rationale, security, CI/CD) as templates for your own projects
• Export: Edit diagrams in diagrams.net (or Lucidchart) and export to PNG/SVG for your portfolio or docs

---

Roadmap

• EKS‑based variant (service mesh, gRPC, canary/blue‑green)
• Serverless variant (API Gateway + Lambda + EventBridge)
• Multi‑Region active/passive with Route 53 ARC and data replication strategies
• Deeper observability with OpenTelemetry and Managed Prometheus/Grafana
