Paper discusses the core concepts of an MSA’s inner and outer architecture and how to leverage middleware in implementing a microservice architecture efficiently

WSO2 delivers the only fully integrated open source enterprise middleware platform to support today’s enterprise environments—internally and across the cloud, mobile devices, and Internet of Things.

The microservice architecture is fast becoming a popular pattern in today’s agile enterprises.

The microservice architecture (MSA) is fast becoming a popular pattern in today’s agile enterprises. Its iterative architectural approach and development methodologies are attracting the interest of architects who need to ensure continuous, agile delivery and the flexible deployment of complex, service-oriented applications. WSO2 has published a new white paper that examines how the WSO2 middleware platform can be used to efficiently implement an MSA in a service-oriented system.

Leveraging Middleware for MSA

The white paper, “Scope Versus Size: A Pragmatic Approach to Microservice Architecture,” was written by WSO2 Vice President of Solutions Architecture Asanka Abeysinghe. He begins by discussing the importance of a microservice architecture in bridging the technologies of two generations. He then explains why architects should give importance to how they would scope out a service rather than merely considering its size.

Next, Asanka reviews the concepts of an MSA’s inner and outer architecture, and he explores the fundamental features that an MSA should contain, including:

  •     Componentization as a service
  •     Organization around business capabilities
  •     Smart endpoints and dumb pipes
  •     Decentralized governance and data management
  •     Infrastructure automation
  •     A design for failure model
  •     Support for evolutionary design (also referred to as continuous design)

Asanka then explains how, by using the correct middleware capabilities, enterprises can fully leverage the advantages provided by an MSA to enable ease of implementation and speed time to market. He concludes with an overview of how the WSO2 middleware platform fits into an MSA and allows architects to meet all their requirements.
