About This Presentation

Serverless, or pay-as-you-go computing via Functions-as-a-Service (FaaS), has become a force to be reckoned with for modern cloud native application development. There is a big, glaring problem, however, that produces challenges for developers looking to embrace FaaS for general application development:

  • FaaS is only for a subset of all use-cases—it’s intended for stateless transformation of data.
  • Most business applications tend to have a significant need for stateful transformations and domain models
  • This results in having to work around this limitation by embedding data access within functions, leading to high coupling, high latency, and contention under increased load.

Learn from Viktor Klang, co-creator of Cloudstate and Head of Cloud Engineering at Lightbend, as we demonstrate with Cloudstate how domain entities offered as stateful services make Serverless applicable in a much broader scope than present-day FaaS.

Using techniques such as Event Sourcing, and scalable eventual consistency via Conflict-Free Replicated Data Types (CRDTs), Cloudstate offers a broad range of state management strategies.

About Cloudstate is an open initiative, led by Lightbend, to solve the problems of the first generation of FaaS by creating an open standard and a reference implementation for a polyglot, poly-DB store, poly-API, serverless platform based on industry standards such as gRPC and Kubernetes, and state-of-the-art technology for Reactive Systems like Akka.
