| Best-of-breed services | Use each cloud's strengths | Medium |
| Regulatory/data residency | Regional providers | Medium |
| Disaster recovery | Active-passive across clouds | High |
| M&A integration | Federate existing environments | Very High |
Multi-Cloud Architecture Patterns
Pattern 1: Active-Passive DR
┌─────────────┐ ┌─────────────┐
│ Primary │────▶│ Standby │
│ (AWS) │Sync │ (Azure) │
└─────────────┘ └─────────────┘
Pattern 2: Service-Level Split
┌─────────────┐ ┌─────────────┐ ┌─────────────┐
│ Compute │ │ Data/AI │ │ Edge │
│ (AWS) │ │ (GCP) │ │ (Cloudflare)│
└─────────────┘ └─────────────┘ └─────────────┘
Pattern 3: Portable Workloads
┌─────────────────────────────────────┐
│ Kubernetes (EKS/GKE/AKS) │
│ Same manifests, any cloud │
└─────────────────────────────────────┘
Multi-Cloud Tooling
| Category | Tools | Purpose |
|---|---|---|
| IaC | Terraform, OpenTofu, Pulumi, Crossplane | Portable infrastructure |
| K8s | Cluster API, Rancher, Fleet | Multi-cluster management |
| Networking | Cilium, Istio, Submariner | Cross-cluster connectivity |

| Cost | Finout, Cloudability, Vantage | Unified billing |
Serverless-First Architecture
Serverless Decision Matrix
| Workload | Serverless Fit | Recommended Service |
|---|---|---|
| API Backend | ✅ Excellent | Lambda, Cloud Functions, Cloud Run |
| Event Processing | ✅ Excellent | EventBridge, Event Grid, Eventarc |
| ML Inference | ⚠️ Conditional | SageMaker Serverless, Vertex AI |
| Long-running | ❌ Poor | ECS Fargate, Cloud Run (long) |
| High-throughput | ⚠️ Conditional | Provisioned concurrency |
| Stateful | ❌ Poor | Use external state stores |

Cold Start Mitigation
| Strategy | Impact | Effort |
|---|---|---|
| Provisioned Concurrency | Eliminates cold starts | Low (config) |
| ARM64 (Graviton2/3) | 20-30% faster init | Low (arch flag) |
| Smaller bundles | Faster download | Medium (tree-shake) |
| SnapStart (Java) | Sub-second startup | Low (config) |
| Keep-warm pings | Reduces cold starts | Low (cron) |
FinOps: Cloud Cost Optimization
The FinOps Framework
┌────────────────────────────────────────────────────────────┐
│ FINOPS LIFECYCLE │
├──────────────┬──────────────┬──────────────┬──────────────┤
│ INFORM │ OPTIMIZE │ OPERATE │ GOVERN │
├──────────────┼──────────────┼──────────────┼──────────────┤
│ • Visibility │ • Right-size │ • Automate │ • Policies │
│ • Allocation │ • Commit │ • Monitor │ • Budgets │
│ • Anomalies │ • Schedule │ • Forecast │ • Chargeback │
│ • Benchmarks │ • Serverless │ • Refactor │ • Reporting │
└──────────────┴──────────────┴──────────────┴──────────────┘
Quick Wins (Implement This Week)
| Optimization | Savings | Effort |
|---|---|---|
| Delete unattached EBS volumes | 5-15% | 1 hour |
| Remove old snapshots | 10-20% | 1 hour |
| Enable S3 Intelligent Tiering | 20-50% on storage | 30 min |
| Right-size EC2/RDS | 20-40% | 2 hours |
| Enable Compute Savings Plans | 30-50% | 1 hour |
| Delete idle load balancers | $20-50/mo each | 30 min |
| Enable RDS instance scheduling | 65% (dev envs) | 1 hour |
Rightsizing Methodology
## 1. Collect utilization (2 weeks)
aws cloudwatch get-metric-statistics --namespace AWS/EC2 --metric-name CPUUtilization --dimensions Name=InstanceId,i-12345 --start-time 2024-01-01 --end-time 2024-01-15 --period 3600 --statistics Average,Maximum
## 2. Analyze: if Max < 40% and Avg < 20% → downsize
## 3. Test in staging → apply to production
## Automated with AWS Compute Optimizer
aws compute-optimizer get-ec2-instance-recommendations
Commitment Strategies
| Option | Discount | Commitment | Flexibility | Best For |
|---|---|---|---|---|
| On-Demand | 0% | None | Full | Unpredictable |
| Savings Plans | 30-50% | 1-3 years | High (any EC2/Fargate) | Stable baseline |
| Reserved Instances | 40-60% | 1-3 years | Low (specific instance) | Steady state |
| Spot Instances | 60-90% | None | None (can interrupt) | Batch, CI/CD |

| Refactor | Cloud-native | High | High | Strategic apps |
Migration Wave Planning
Wave 1 (Months 1-3): Non-critical, stateless, dev/test
→ 20% of apps, validates process
Wave 2 (Months 3-6): Low-risk production, stateless
→ 30% of apps, builds confidence
Wave 3 (Months 6-12): Business-critical, stateful
→ 40% of apps, requires planning
Wave 4 (Months 12+): Complex, regulated, mainframe
→ 10% of apps, specialized approach
