I was working and continue to work with alternative in-memory data grid solutions (GemFire in the past, Hazelcast currently). Oracle Coherence has a strong advantage for sophisticated and performance-critical solutions.

We did research on all the open source products, and we initially applied the solution with EH cache. That was pretty good. When we wanted to scale higher, to about six million users, it wasn’t going to work. We don’t care about the expense because Oracle is our partner, and more. If you are a small business that cannot afford million-dollar products, you would go for an EH cache. We can afford a million-dollar product, so we are doing that.

I did not previously use a different solution.

We’ve never switched, been using Oracle suite for long time.

We did not have a previous solution.

We chose this product, because it was one of the most popular distributed caching in memory cache, which supports capabilities like Cassandra and MongoDB.

Not before, but after Coherence, we had the chance to work for years with Hazelcast. It's an open source and a cheaper competitor.

I did not previously use a different solution, but if we would do the application from ground zero, we would, most probably, choose Hazelcast.

I used .NET in-memory cache and this has a single process limitation, hence each node had to keep its own data. Oracle Coherence excels as it is a distributed cache.

I did not use a different solution before Oracle Coherence. My company was using Memcached before I started working there, but I always used Coherence.

We did not have a different solution before. We were looking for this solution. The response time is the key. It was really touching. When we really started with five million customers, the response time was four seconds. The customer base was increasing, and that became five seconds; and then six seconds. It just kept going up. So we thought we needed to come up with some solution for reducing the response time.

We were looking for a cost-effective solution. Nowadays, any business must keep the operating cost in mind. Why do we want to go for the cloud? Because we are spending so much on the hardware. I really want to make sure my investment in hardware brings a good cost-effective return on the investment.

I keep everything in mind. Of course, I also look for the security and scalability.

In this case, Coherence was the incumbent technology.

We tried several approaches towards our goal of performance improvement. This was the most likely solution and hence was used.

We used Ehcache in a previoius project and switched to Coherence. Ehcache should be installed in each JVM but Oracle Coherence is a central place, provides response from cache. Space consumption is much less.

No.

It was a company decision as this is a commercial product with guarantee of support.

Yes, I used to use Redis, Aerospike, Cassandra, etc. Why coherence? It was a company decision.

Before using Oracle Coherence, we tried using Ehcache. We switched because of replication, grid support, and a few other reasons.

We did not try a different solution, but we searched for a solid product with a good reputation in a financial organization.
