[WSO2 Integration Summit New York 2019] Emerging Architecture Patterns: API-centric & Cell-based

44 views

Published on

The number of microservices running in enterprises increases daily. As a result, service composition, governance, security, and observability are becoming a challenge to implement and incorporate. A “cell-based” architecture is an approach that can be applied to current or desired development and technologies to address these issues. This technology-neutral approach helps cloud-native dev teams become more efficient, act in a more self-organized manner, and speed overall release times.

In this deck, Asanka introduces the "cell-based" reference architecture, which is API-centric, cloud-native, and microservices-friendly. He explains the role of APIs in the cell-based approach, as well as examine how real applications are built as cells. Asanka explores the metrics and approaches that can be used to measure the effectiveness of the architecture and explore how organizations can implement the cell approach.

  24. 24. Business vs technical services picture credit: https://www.flickr.com/photos/arpadlukacs/
  25. 25. Service: Technical definition A code exposes through an interface that describes a collection of operations that are network accessible using a standardized messaging protocol.
  26. 26. Service: Business definition Software components that can be spontaneously discovered, combined, and recombined to provide a solution to a business problem.
  27. 27. Microservice: Technical definition A microservice must have a single purpose and be loosely coupled in design and deployed independently of other microservices. "Micro" is a concept of scope rather than size.
  28. 28. Microservice: Business definition Microservices is an approach to application development in which a large application is built as a suite of modular components or services. These services are built around business capabilities.

  31. 31. Cell-based Reference Architecture
  32. 32. Component: Atomic Units A component represents a process or business logic running in a container, serverless environment, or an existing runtime. A component is designed based on a specific scope, which can be independently run and reused at the runtime.
  33. 33. Cell: Units of Enterprise Architecture A cell is a collection of components, grouped from design and implementation into deployment. A cell is independently deployable, manageable, and observable.
