Serverless Architecture Patterns
Manoj GanapathiChief Architect, [email protected]@manojgr
Serverless: Core Principles❖ Functions are the unit of deployment and scale
❖ Use Serverless to solve specific problems, not every application can be written as Serverless.
❖ Keep your functions Stateless – use cloud storage for WIP state
❖ Functions should:
❖ “Do One Thing”– Single Responsibility Principle
❖ Be Idempotent
❖ Finish as fast as possible
“Rethink your application as an orchestra of autonomous functions”

Key Patterns
Messaging and Command• Decouple services by introducing a queue• Typically in asynchronous messaging in web apps and services to take the
load off the application• Also shows the Command pattern (encapsulated implementation for a
standard interface)

Fan Out
• Topic-Subscription scenario. • For e.g: Once a video is uploaded, you may want to encode them in
multiple formats in parallel and also transcribe

Pipes and Filter
• To manage a sequential series of tasks – like a data pipeline• Functions can work as a pipe (connector) or a filter (transformation)
