Sizing has a fairly large crystal ball component :) Still, here are a few of the rationals:
- We have the same amount of data, so same SSD size (obvious)
- We still want 2 CPUs because that's our standard and wasting a socket usually does not make much sense (for the details of that reasoning, ask Rob, I barely understand what I'm talking about here)
- We might be able to get away with less RAM, but seeing the current workload, where a single query can start allocating like crazy, it seems unlikely that we could allocate much less to the JVM (we need to size for peak consumption, not average). Also, less RAM => less cache, so probably a higher per query latency.
- We are trying to standardize our server builds (easier management, spares, ...)
