A microservices architecture splits an application into many small services allowing teams to innovate faster and achieve massive scale.Join our cloud transformation webcast
Microservices architecture is commonly understood by comparing it to a legacy "monolith" application architecture. With a monolithic architecture, all of the components are part of a single unit. Everything is developed, deployed, and scaled together. The app must be written in a single language, with a single runtime. Different teams working on different parts of the app need to coordinate in order to make sure they don't affect each other's work. For example, one part of the app may depend on a module that needs a specific version say 1.8, which another teams needs the same module, but requires the 1.7 version because 1.7 is incompatible with another dependency. In a monolithic app you have to pick one or the other. Similarly, everything is deployed as a single application so code must be tested and deployed together.
With microservices, each component is broken out and deployed individually as services and the services communicate with each other via API calls.
While every organization defines microservices differently, Martin Fowler's quintessential article on microservices defines 9 components that most microservice architectures have in commons.
Folwer went into more detail about each of these components in this talk from GOTO.
Building applications with a microservices architecture, or decomposing a legacy monolith into microservices increases velocity, flexibility, and scalability, at the cost of simplicity. Monoliths are simple to build, deploy, and debug, but are very hard to scale. By using a more complex microservice architecture engineering organizations gain several benefits.
With GitLab you can commit your code and have all the tools you need integrated in a single application. You won't have to stitch together 10 tools for every project.
Using an integrated solution to manage your microservices helps you avoid having engineers siloed off with their respective teams and tools. Creating visibility among teams and getting rid of the need for handoffs leads to a faster DevOps lifecycle while also ensuring that your projects deploy and remain stable.

While GitLab is great for microservices today, there are several features on the roadmap to make it even better.
