In this age of digital transformation, digital systems must now, more than ever, support fast-paced environments characterised by constantly changing requirements and very short time-to-market cycles.
Microservice architectures are not intended to model complex requirements in large, inflexible, software monoliths characterised by internal dependencies. Instead, these architectures create solutions using large numbers of small, independent modules. These microservices can be implemented in a polyglot manner, i.e. using the optimum language for each requirement. They communicate with each other using APIs and have a clearly defined scope of functions. Their independence makes them easy to swap out and modify. This flexibility makes microservice architectures perfect for agile software development in distributed DevOps teams and for continuous delivery processes with optimum time-to-market performance.
Many projects contain requirements which can be ideally served using microservices. Since the initial fundamental concepts of microservices were first mooted several years ago, we have, therefore, focused very intensively on what we consider to be an extremely sustainable technological concept.
