What is Serverless
No infrastructure management
Using fully managed services enables developers to avoid administrative tasks and focus on core business logic. With a serverless platform, you simply deploy your code, and it runs with high availability.
Dynamic scalability
With serverless computing, the infrastructure dynamically scales up and down within seconds to match the demands of any workload.
Faster time to market
Serverless applications reduce the operations dependencies on each development cycle, increasing development teams’ agility to deliver more functionality in less time.
More efficient use of resources
Shifting to serverless technologies helps organizations reduce Total Cost of Ownership (TCO) and reallocate resources to accelerate the pace of innovation.

FaaS is at the center of serverless
Single Responsibility
Functions are simple, reusable bits of code that do a specific job, take an input and give back a result.
Short-Lived
Functions don't stay after they finish doing their job, making resources available for more tasks.
Stateless
Functions don't remember things or depend on what other tasks are doing.
Event-driven and scalable
Functions react to set events and quickly make copies as many times as necessary.
Workflow and orchestration with Durable Functions
Manageable sequencing
External events correlation
Process Monitoring
Fanning out and fanning in
Http-based async long-running APIs
Human Interaction
Function Chaining/sequencing
Fan out/fan in
Evolution of .NET on Functions
- Bind to new types from the latest Azure SDKs
- You own main() and all dependencies
- Improved reliability
- Modernized .NET model
- Rich dependency injection
- Invocation middleware
- Better extensibility
- Performance gains
- OpenTelemetry support
- Deeper ASP.NET integration
- more to come
