🌁Software Engineering: Microservices (Definitions)

"In computing, a software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic Application Programming Interface (API). These services are small and highly decoupled and focus on doing a small task." (Pierre Pureur & Murat Erder, "Continuous Architecture", 2015)

"Are an IT architectural pattern for decoupling dependencies between complex software applications and enabling independent processes that than work together through independent APIs." (Anna Wiedemann et al, "Transforming Disciplined IT Functions: Guidelines for DevOps Integration", 2021)

"It is a specific way of decomposition of services in a greater granularity. Also, microservice represents a capability of the business process in a lesser level of abstraction than a service, Then, a microservice is a service but with greater granularity or in a lesser level of abstraction." (Laura C Rodriguez-Martinez et al, "Service-Oriented Computing Applications (SOCA) Development Methodologies: A Review of Agility-Rigor Balance", 2021)

"A piece of code or complete application that does one thing and does it well." (Forrester)

"Microservices is both an approach to software architecture that builds a large, complex application from multiple small components which each perform a single function (such as authentication, notification, or payment processing) and the term for the small components themselves. Each microservice is a distinct unit within the software development project, with its own codebase, infrastructure, and database. The microservices work together, communicating through web APIs or messaging queues to respond to incoming events." (NGINX) [source

"Microservices refer to the thousands of independent web standards, programming languages, database platforms, and web server components that are found in the contemporary software development lifecycle as developer tools." (VMWare) [source]

"The microservices architecture is a design approach to build a single application as a set of small services. Each service runs in its own process and communicates with other services through a well-defined interface using a lightweight mechanism, typically an HTTP-based application programming interface (API). Microservices are built around business capabilities; each service is scoped to a single purpose." (Amazon)
