AWS Solutions Architecture
This section brings together my AWS-focused implementation guides and the architecture principles behind them. It will grow from foundational account security and infrastructure delivery into complete workload architectures aligned with the AWS Well-Architected Framework.
Current AWS Guides
Identity & Infrastructure Foundations
- Bootstrap AWS IAM and an S3 Backend for Terraform — secure initial access, remote state, encryption, versioning, and public-access controls.
- Terraform, OpenTofu, and Terragrunt Delivery — reusable infrastructure modules, remote state, validation, and CI/CD patterns applicable to AWS environments.
Containers & Compute
- Set Up Karpenter on Amazon EKS — dynamic node provisioning and workload-aware compute capacity.
- Amazon EKS Auto Mode with S3 — secure workload access to object storage and cost-conscious managed Kubernetes operations.
Reliability & Operations
- Business Continuity: RPO, RTO, and MTD — requirements that drive AWS backup, replication, and recovery architecture.
- Kubernetes Resource Management — capacity practices that inform EKS performance and cost decisions.
- Observability and Reliability — operational patterns to carry into Amazon CloudWatch and managed observability services.
AWS Well-Architected Lens
New AWS articles should explain their decisions against these pillars:
| Pillar | Questions addressed |
|---|---|
| Operational Excellence | How is the workload deployed, observed, operated, and improved? |
| Security | How are identity, data, networks, and detection protected? |
| Reliability | How does the design tolerate failure and recover? |
| Performance Efficiency | Why were these services and scaling models selected? |
| Cost Optimization | How are usage, pricing models, and waste controlled? |
| Sustainability | How does the design minimize unnecessary resource consumption? |
Architecture Roadmap
Planned coverage includes:
- Multi-account governance with AWS Organizations and Control Tower
- VPC, Transit Gateway, Route 53, and hybrid connectivity patterns
- EC2, Lambda, ECS, and EKS workload-selection guidance
- S3, EBS, EFS, RDS, DynamoDB, and database-selection trade-offs
- IAM Identity Center, KMS, WAF, GuardDuty, Security Hub, and centralized logging
- Multi-AZ, multi-region, backup, and disaster-recovery architectures
- Migration assessment, landing zones, modernization, and FinOps
These roadmap items are future work; the links above represent currently published, hands-on evidence.
