1. Multi-Cloud & Provider Selection
Avoiding vendor lock-in while leveraging best-of-breed services.
- Decision Matrix: Evaluate AWS (Breadth), Azure (Enterprise/MSFT stack), and GCP (Data/AI/K8s).
- Control Plane: Design for single-pane-of-glass management using HashiCorp or Anthos.
- Portability: Focus on containerized workloads (Docker/K8s) to move between clouds easily.
2. Hybrid Cloud Architecture
Bridging on-premises and public cloud.
- Connectivity: Implement AWS Direct Connect, Azure ExpressRoute, or GCP Cloud Interconnect.
- Data Locality: Keep sensitive data on-prem while using cloud for burstable compute.
- Operational Consistency: Use tools like Nutanix or Azure Stack to maintain the same environment across sites.
3. Cloud-Native Networking & Security
Zero Trust and Secure Access.
- VPC Design: Subnet isolation, NAT Gateways, and Peering.
- Security Audit: Scan for exposed S3 buckets, permissive Security Groups, and over-privileged IAM roles.
- SSO/IAM: Centralize identity management with OIDC/SAML.
4. Infrastructure as Code (IaC) & Automation
- Terraform/OpenTofu: Modern state management and modular design.
- GitOps: Automate deployments via ArgoCD or Flux.
- Disaster Recovery (DR): Define RTO (Recovery Time Objective) and RPO (Point Objective) across regions.
5. FinOps & Cost Optimization
- Right-sizing: Monitor utilization and downsize over-provisioned instances.
- Reserved/Spot: Leverage Reserved Instances for baseline loads and Spot for batch jobs.
- Tagging Strategy: Enforce strict tagging for cost allocation and billing accountability.
🛠️ Execution Protocol
- Audit Infrastructure: Check the current cost optimization status.
Review: .agent/skills/cloud-architect-master/resources/cost_optimization_checklist.md - Design Architecture: Build multi-cloud or hybrid solutions.
- Simulate Cost: Estimate expenses and optimize before deployment.
