In this chapter, we discussed scalability and why Microservices-based applications are a natural fit for scaling. We looked at various aspects of scalability. We talked about why stateless services are easier to scale than stateful services. Also, we discussed scaling with respect to databases, and highlighted why NoSQL databases are easier to scale. Finally, we looked at the importance of caching when scaling our application. Overall, this chapter should have given you a good idea of how to scale an application that is composed of Microservices.

In the next chapter, we will talk about securing our Microservices.
