What stage of Software development life-cycle do Microservices operate

Posted 10 April 2018 - 02:51 AM

What stage of Software development life-cycle do Micro-services operate like the development of new REST APIs which are intended to replace a current monolithic application with legacy code?

They operate in all phases of the lifecycle. For your scenario where the creation of the microservice(s) is initiated by the need to replace part of a monolithic system, its origin may start at the maintenance phase, but you still need to get budgets, requirements, designs, implementaions, etc. to get the new microservice into production.

Other times, the design phase reveals the need for a microservice. Other times, the implementation phase is what evolves the creation of a microservice. Or testing may require a microservice to make testing easier.

I am confused, or rather you are, with what the SDLC is. The life-cycle isn't a single entity. It is the design, implementation, and maintenance of entities that are involved.

So, a legacy system. When a point is reached that it needs to be phased out, new designs are created, implemented, and now maintained. If a microservice exists that a system is using and needs something added to it, the process is the same for a new piece, the same as if it were a totally new system, from the SDLC approach.
