Good one. Few things to learn from this- Follow this only if your application is really big, used heavily & you need to have so many clusters & nodes. Before trying to make the infrastructure massive, try to make it simpler, as real technical challenge is to keep the platform simple & sorted. So I think, here also this whole platform can reduce its weight significantly. I find it funny that in such companies first the whole infra is made too complex with hell lot of abstractions in the name of transparency & then developer is expected to increase his/her delivery speed over that must be aware about what is behind those abstractions.
