Proposed Methodology for Designing a Microservice Architecture

The changing needs of the enterprise require the manageability of its information system. Therefore, it is crucial to absorb these changes by orienting the design of the information system towards a modern architecture that decomposes the monolithic application into autonomous services. This paper proposes an enterprise architecture methodological framework to design the so-called microservice architecture known as MSA. Our approach is to describe the similarities between the MSA style of architecture and the service-oriented architecture known as SOA, the latter having a rich research literature focused on exploiting the methodology for designing services in a service architecture. The result of the comparative study indicates that the ideology for designing a SOA is identical as MSA which ultimately relies on decomposing applications into smaller components with a smaller and more manageable footprint. Thus, we conclude that it is preferable to use the adapted enterprise architecture methodology for SOA to design MSA.
