Evaluation Process

Step 1: Define Requirements

## Requirements
- Scale: [Expected users/requests]
- Performance: [Latency requirements]
- Budget: [Monthly/yearly budget]
- Team: [Current skills and size]
- Timeline: [Implementation deadline]

Step 2: Identify Options

Research 3-5 viable options:

Current market leaders
Rising alternatives
Team-familiar options

Step 3: Proof of Concept

Build minimal POC for top 2-3 options:

Core functionality
Integration test
Performance benchmark

Step 4: Total Cost Analysis

| Licensing | $ | $

| Infrastructure | $ | $

| Development | $ | $

| Training | $ | $

| Maintenance | $ | $

| Total (3 yr) | $ | $

Step 5: Risk Assessment

| Vendor lock-in | Low/Med/High |

Technology obsolescence

Skill availability

Security concerns

Build vs Buy

Build When

Core competitive advantage
Unique requirements
Long-term cost savings
Team has expertise

Buy When

Commodity functionality
Time to market critical
Ongoing maintenance burden
Industry standard exists

Decision Tree

Is it core to your business?
├── Yes → Does expertise exist?
│   ├── Yes → Build
│   └── No → Buy (for now)
└── No → Buy or use open source

Migration Planning

Migration Phases

Assessment - Current state analysis
Planning - Target architecture
Preparation - Team training, tooling
Migration - Incremental rollout
Validation - Testing, monitoring
Cutover - Final switch
Optimization - Post-migration tuning

Risk Mitigation

Run parallel systems
Feature flags for rollback
Comprehensive testing
Staged rollout
Clear rollback plan
