04 Breaking Change

In this chapter, we’re going to focus on the ties between cohesion and splitting applications. That is by reviewing another use case of a split done at RapidAPI, an internal one done between the Monetization and the Analytics teams (which was later renamed to Data).

In this chapter, we’re going to review a use case with a non-beneficial outcome. By it we’re going to finally see the entire picture of what splitting application has to do with Throughputs, Bottlenecks and the Change Stream. And it would end with a twist I made sure you won’t see coming!

What is the correct size of an application? Maybe before answering it, we better first pose a more important question - why and how it matters.

If it’s not about size, we are left to wonder what Microservices really are. In this chapter we’ll try to figure it out, first by continuing ruling out what it isn't by taking a stroll down memory lane.
