Serverless

• Dynamic resource utilization, "scale to zero"
• Billing per message
• Focus on business logic
• Easy integration with platform services

Service Block

Idealized Serverless Architecture

What is Missing?

• Architectural cohesion
• Observability
• On premise and BYO services
• Vendor neutrality

Abstractions are a good thing

But not everything is a function

Higher level of abstraction means:

• Higher value line :-)
• Less control :-(

But: you need to pick your battles. And the value line is not fixed.

Not all abstractions are helpful for all problems.
