COMPRSA’s microservices development makes it possible for organisations to get started with the Internet of Things right away.
The microservice architecture structures an application as a collection of loosely coupled services, which implement business capabilities and the architecture enables the continuous delivery and deployment of large, complex applications.
Instead of having one large code base that all developers utilize, there are numerous smaller code bases managed by small and agile teams. The only dependency these code bases have on one another is their APIs. This means that as long as you maintain backwards and forward compatibility each team can work in release cycles that are decoupled from other teams. There are some scenarios where these release cycles are coupled, where one service depends on another or depends on a new feature in another service, but this is not the usual case.
Monolithic apps are good for small scale teams and projects, but when you need something that has a larger scale and involves many teams, it starts to become problematic. It’s much harder to make changes, as the code base becomes bigger and more people make changes to it.
Most large scale web sites have evolved from a monolithic architecture to a microservice architecture.
Services communicate using either synchronous protocols such as HTTP/REST or asynchronous protocols. Services can be developed and deployed independently of one another. Each service has its own database in order to be decoupled from other services.
Applications built as a set of modular components are easier to understand, easier to test, and most importantly easier to maintain over the life of the application. It enables organizations to achieve much higher agility and be able to vastly improve the time it takes to get working improvements to production. This approach has proven to be superior, especially for large enterprise applications which are developed by teams of geographically and culturally diverse developers.
Microservices depend not just on the technology being set up to support this concept, but on an organization having the culture, know-how, and structures in place for development teams to be able to adopt this model. Microservices are a part of a larger shift in IT departments towards a DevOps culture, in which development and operations teams work closely together to support an application over its lifecycle, and go through a rapid or even continuous release cycle rather than a more traditional long cycle.
