At Netflix, we also heavily embrace a microservice architecture that emphasizes separation of concerns. The data warehouse is not designed to serve point requests from microservices with low latency. Therefore, we must efficiently move data from the data warehouse to a global, low-latency and highly-reliable key-value store.

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. They are particularly important in distributed systems, such as microservices architectures. A platform approach, on the other hand, presents a more effective option for understanding observability as a whole.

While a service-oriented architecture addressed the problems of a centralized database architecture, each service was still using traditional data management systems.
