A “microservice” is an innovative, results-oriented perspective on software development and software architecture that focuses on achieving goals rather than deploying specific technology. Microservices can be implemented regardless of development methodology, within a range of environments (responsive to less responsive).
But what does this mean in a real IT project setting?
Existing and new technologies are both used in this conceptual model. Development teams are pulled together based on their cross-functional business skills, and the software is split up into autonomous, executable components. The idea is to first cluster various types of topic-based expertise in teams with a maximum of 8–12 developers, then let the experts bring their expertise to bear within the cluster.
- Efficiency and risk management: In addition to reducing the total risk of software development, an enormous opportunity is hidden within the demand for operability: the possible reusability of components and associated increases in efficiency. In this model, software and associated technology can be carved up vertically as well as stratified horizontally. This increases goal orientation in development and reduces the complexity of the total application.
- Dependability and robustness: When implemented in distributed environments, microservices can be controlled and monitored independently of each other. The failure of one service does not therefore mean the failure of the whole application because deployments are executed and controlled on a component basis. Focusing on and testing for robustness in each individual component creates strength, especially when the motivation for this is defined as a goal of complete software robustness.
- Expandability and sustainability: The aim of the microservices model is to integrate new components simply, thus expanding or modernising an application’s functions as cost-efficiently as possible. By focusing on individual components, it becomes possible to raise the degree of automation involved in testing to deployment as well as the individual time to market for new requests.
- Organisation: Many IT areas are classified by competencies, with tasks allocated within these competence teams. In the case of microservices, it's less the competencies than individual skills that are the focus. Proximity to an area of specialisation also has decisive impact on a project’s success. Interdisciplinary cooperation per component is also placed upstream of mass production.
- Procedural models: It is important that the goal of robustness is top of mind when the project is conceived and organised. Success factors include: clear requirements, precise encoding rules, and code that is integrated with quality control.
- Project culture: The core of this architectural principle requires a mind-shift for each participant, to an interdisciplinary, solid collaboration that has a shared goal and a shared orientation to quality. The guiding principle is a managed culture of change, which presumes an interdisciplinary mentality. The responsibility for mutual success lies in the mind of each individual.
