[2017.02 Meetup #10] [TALK #2] Ricardo Costa - Serverless code with Azure Functions

In this talk, I'll provide an overview of Microsoft's serverless solution: Azure Functions. We'll do a quick tour of its features. We'll learn about its architecture, the programming model and, very important, its pricing.

Ricardo Costa is a solutions architect at |create|it|. He's been developing and architecting integration solutions for almost 12 years. His main focus is on Software Architecture, Enterprise Integration and Azure solutions.

4. Serverless •  “Serverless can also mean applica5ons where some amount of server-side logic is s5ll wriPen by the applica5on developer but unlike tradi5onal architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invoca5on), and fully managed by a 3rd party. One way to think of this is ‘Func5ons as a service / FaaS’.” •  Mar5n Fowler - hPps://mar5nfowler.com/ar5cles/serverless.html
5. Azure Func9ons •  Serverless code •  Event-driven + triggers + schedules •  Can expose HTTP endpoints •  Variety of languages. •  Single purpose. •  Sta5c. •  Start, execute, stop.
