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.

Therefore, we must efficiently move data from the data warehouse to a global, low-latency and highly-reliable key-value store.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
