The Multi-Cloud Myth
"We need to be cloud-agnostic to avoid vendor lock-in." This sounds smart. It is usually catastrophic.
The Lowest Common Denominator
To run on both Cloud Provider and Cloud Provider, you cannot use:
- Cloud Provider Lambda (Must use generic K8s)
- DynamoDB (Must use generic Mongo/Postgres)
- Aurora (Must use generic RDS) You strip away all the "Superpowers" of the cloud provider and treat them as dumb utility providers. Result: You pay the Cloud Premium price but get Commodity Data Center value.
The Talent Tax
You essentially need two distinct engineering teams.
- "I'm an Cloud Provider Expert."
- "I'm an Cloud Provider Expert." Finding people who are experts in both networking stacks is impossible or expensive.
Single vs Multi Cloud
| Dimension | Single Cloud | Multi-Cloud |
|---|---|---|
| Discounts | Maximized (Volume Tiering) | Diluted (Split spend) |
| Complexity | High | Extreme (Abstraction Layers) |
| Leverage | High (Vendor invests in you) | Low (You are a disloyal customer) |
Decision: Do you need Multi-Cloud?
