…of the MTBF of Cisco switches (There is a subtle difference between MTBF and MTTF, but for our purposes we can treat them the same)
It is claimed that when W + R > N you can get consistency. But it's not true, because without distributed ACID transactions, it's never possible to achieve W > 1 atomically.
Consider W=3, R=1 and N=3. If a network failure or more likely a client/app tier failure (hardware, OS or process crash) happens during the writing of data, it's …
…will inevitably break. We want a resilient infrastructure where ouris small and MTBF isn't even a consideration.
Every employee atis behind our build, measure, iterate cycle and operations is at the center for this process. Without careful cultivation of our culture, we wouldn't be optimized for discovery.
The key to the cell is you are creating a scalable and robust MTBF friendly service. A service than can be used as a bedrock component in a system of other services coordinated by a programmable orchestration layer. It works just as well in a data center as in a cloud. If you are looking for a higher level organization pattern, the Cell Architecture is a solid choice.
