- Budget constraints: [Migration budget, ongoing operational budget]

## Cloud Strategy & Approach

**Migration Strategy:**
- Cloud-first approach: [New workloads, application modernization]

- Cloud provider selection: [AWS, Azure, GCP comparison and selection]

**Migration Patterns (6 Rs):**
- Rehost (Lift and Shift): [Minimal changes, quick migration, cost optimization]
- Replatform (Lift, Tinker, and Shift): [Minor optimizations, managed services]
- Refactor/Re-architect: [Cloud-native redesign, microservices, containers]
- Repurchase: [SaaS replacement, commercial solutions]
- Retire: [Application decommissioning, consolidation]
- Retain: [Keep on-premises, future migration consideration]

## Target Architecture Design

**Cloud Architecture:**
- Compute services: [EC2/VMs, containers, serverless functions, managed services]
- Storage architecture: [Object storage, block storage, file systems, databases]
- Network design: [VPC, subnets, connectivity, load balancing, CDN]
- Security architecture: [IAM, encryption, network security, compliance]
- Monitoring and logging: [CloudWatch, Application insights, logging strategy]

**Well-Architected Framework:**
- Operational Excellence: [Automation, monitoring, continuous improvement]
- Security: [Identity management, data protection, infrastructure protection]
- Reliability: [Recovery planning, change management, failure management]
- Performance Efficiency: [Resource optimization, monitoring, trade-offs]
- Cost Optimization: [Cost-effective resources, matching capacity, optimizing]
- Sustainability: [Energy efficiency, carbon footprint reduction]

## Migration Planning & Execution

**Migration Waves:**
- Wave 1: Low-Risk Workloads (Months 1-3) - Development and test environments
- Wave 2: Medium-Risk Workloads (Months 4-6) - Business applications with dependencies
- Wave 3: High-Risk Workloads (Months 7-9) - Mission-critical applications

**Migration Execution Process:**
1. Assessment & Planning - Workload discovery and analysis
2. Design & Build - Target architecture design and provisioning
3. Migrate & Deploy - Data migration and application deployment
4. Validate & Cutover - Testing and production cutover
5. Optimize & Operate - Performance tuning and monitoring

## Data Migration Strategy

**Data Assessment:**
- Data inventory: [Databases, files, volumes, size, growth rate]
- Data classification: [Sensitivity, compliance, retention requirements]
- Data quality: [Accuracy, completeness, consistency, timeliness]
- Data relationships: [Dependencies, referential integrity, synchronization]

**Migration Approaches:**
- Bulk Transfer: [One-time large data movement, offline migration]
- Incremental Sync: [Initial bulk + ongoing incremental updates]
- Streaming Migration: [Real-time continuous data synchronization]
- Hybrid Approach: [Combination based on data characteristics]

## Security & Compliance

**Security Framework:**
- Identity and access management: [SSO integration, RBAC, MFA]
- Network security: [VPC, security groups, NACLs, WAF]
- Data protection: [Encryption at rest, in transit, key management]
- Monitoring and logging: [CloudTrail, security monitoring, SIEM integration]
- Compliance: [SOC, ISO, HIPAA, GDPR, industry-specific requirements]

**Compliance Considerations:**
- Data residency: [Geographic requirements, data sovereignty]
- Regulatory compliance: [Industry regulations, audit requirements]
- Privacy requirements: [GDPR, CCPA, data protection]
- Security certifications: [Cloud provider certifications, shared responsibility]

## Cost Management & Optimization

**Cost Modeling:**
- Migration costs: [Professional services, tools, downtime, training]
- Operational costs: [Compute, storage, network, support, management]
- Cost comparison: [On-premises vs. cloud TCO analysis]
- ROI calculation: [Break-even analysis, payback period, net present value]

**Cost Optimization Strategies:**
- Right-sizing: [Instance optimization, storage optimization, performance tuning]
- Reserved capacity: [Reserved instances, savings plans, committed use discounts]
- Spot instances: [Workload suitability, interruption handling, cost savings]
- Auto-scaling: [Dynamic scaling, scheduled scaling, predictive scaling]

## Success Metrics & Implementation Timeline

**Migration Success Metrics:**
- On-time delivery: [Migration milestones, timeline adherence]
- Budget adherence: [Cost control, budget variance]
- Quality: [Zero data loss, functional correctness, performance targets]
- Risk mitigation: [Risk reduction, incident frequency, severity]

**Implementation Timeline:**
- Months 1-3: Migration foundation and low-risk workloads
- Months 4-6: Core application migration and optimization
- Months 7-9: High-risk workloads and advanced features
- Months 10-12: Full optimization and continuous improvement

**Post-Migration Metrics:**
