Scalability is one of the critical advantages of pursuing the microservice architectural style. We looked at the characteristics of microservice scalability. We discussed the Scale Cube model of scalability and how microservices can scale on the y axis via functional decomposition of the system. Then we approached the scaling problem with the scaling infrastructure. In the infrastructure segment, we looked at the strong capability of Azure Cloud to scale, utilizing the Azure scale sets and container orchestration solutions, such as Docker Swarm, DC/OS, and Kubernetes.

In the later stages of the chapter, we focused on scaling with a service design and discussed how our data model should be designed. We also discussed certain considerations, such as having a split CQRS style model, while designing the data model for high scalability. We also briefly touched on caching, especially...
