It literally all boils down to the budget a team has. Nowadays, even investment banks look for every opportunity to cut cost. Oracle Coherence is a pretty robust and highly configurable cache application that every team should use if they can afford. If they can't, then open source code is their answer.
Oracle Coherence support team is responsive and knowledgeable. We contacted them to ask a couple of design questions about how we were setting up Oracle Coherence based on how we used IBM's Datapower Extreme Scale. They were able to guide us so that we got the design correct the first time and didn't have to go back and re-architect our design later.
Coherence kicks Redis's butt when it comes to performance and feature set. However, it lags far behind in terms of market penetration and cloud readiness.
It's great and efficient with data replication. Excellent with reducing cost on the consumption of asset. Efficient with data warehousing. Terrific with network Management.
