The Cloud/Infrastructure Business Case

Help me evaluate this cloud migration or infrastructure decision in
business terms.

The current setup and its problems: [DESCRIBE]
The proposed change: [DESCRIBE]
The drivers: [COST, SCALE, RELIABILITY, AGILITY]

Provide:
1. The real drivers and whether the change serves them
2. The cost comparison honestly (cloud isn't always cheaper — usage can
   surprise you)
3. The benefits beyond cost (scalability, speed, reliability)
4. The risks (migration, lock-in, ongoing cost, skills)
5. A recommendation with the key assumptions

Be honest that cloud economics depend heavily on usage patterns — flag
where the numbers need real modelling and current pricing.
