Microservice Architecture for DevOps
DevOps and MicroServices are both practices which enable enterprises to have much greater agility and operational efficiency.
What Exactly is DevOps?
DevOps is a way of coordinating the work of software developers and IT Ops to produce a better quality of software, more efficiently than when working as separate silos.
It is a concept of creating a culture of collaboration, wherein developers gain insight into the operation of the product; which in turn, improves solution and management time for issues and promotes faster software releases. The shared production environment reduces the traditional friction between Dev and Ops as it increases visibility between the two silos.
The microservice architecture is a way to create small pieces of functionality as independent services, not dependant on any specific coding language. As such, they are individual blocks, which together can create complex applications with all the functions. The modularity makes it easier to create, test and understand an application.
Microservices offers a wide range of flexibility to modern software. In the case of DevOps, it enables teams to develop independent pieces of functionality in tandem; allowing for incremental releases. This reduces the need to pass around the code from one silo to another, promoting cross-functional teams to build, test, release and monitor the applications.
How do they go Hand in Hand?
The modular nature makes it easier to experiment with new features without crashing down the entire application. A microservice error is only limited to that module. This significantly speeds up the process and reduces manual errors. This means DevOps teams can get more done in less time.
To ensure product quality, continuous testing is added to continuous integration and continuous delivery (or deployment). Achieving continuous quality involves more than testing. Specifically, it includes other elements of quality such as security, alignment with user requirements, business risk mitigation and measured value.
The independent nature of microservices helps DevOps teams accomplish more in less time. Unlike monolithic software where errors can cause the entire application to crash, a microservice defect tends to be limited to that microservice. However, a microservice failure can put other microservices “under stress” which may mean that other microservices are unable to communicate with the microservice that failed.
