We did research on all the open source products.

The product was in use when I joined.

Couchbase and other distributed storage.

Before choosing this product, we evaluated GridGain and Hazelcast.

None. I work as a Oracle partner, so there is no way to consider other options.

Before choosing this product, I did not evaluate other options, because our company has a “Use Oracle Products” policy.

We also evaluated Hazelcast and Infinispan. Simply, Coherence is better than those two. Coherence absolutely outperforms others in terms of scalability, reliability, and performance.

No, I didn't, as Coherence was the strategic cache product to use.

We evaluated Memcached, Redis, and Infinispan.

We have recently evaluated other solutions such as Hazelcast and GridGain.

A side by side POC was done with IBMs eXtreme Scale on a project. I also have experience with Gemfire - and wish I didn’t.

I think this is the only solution we considered. Whenever we really look for a product, first we look whether Oracle has something appropriate. I have been using Oracle for a number of years. I think they always have a solution. They started with the database. Now they have the middleware and the hardware. They have the complete application solutions. You name it and they have it.

Coherence had all the features and benefits we needed.

People here were using Ehcache or other solutions, but we decided to use Coherence as our corporate solution.

I have evaluated/used other products since, and have concluded that Coherence offers slightly superior performance and integrated read/write-through at the cost of technical complexity. Complexity being a huge contributor to risk/cost for projects, I am more likely to use other products as a result.

We have not evaluated other caching products because this an Oracle product and the product/solution was from Oracle too. We tried some streaming alternatives like Spark, etc.

Before choosing this product, I did not evaluate other options. While using the Oracle Fusion Middleware stack, it was always our preferred choice due to its integration capability with available tools.

Before choosing this product, we looked at Terracotta and other custom caching solutions.

Before choosing this product, we did not evaluate other options. The client used the full Oracle stack in their architecture.

Nope, it was a company decision to use Coherence, and I did not have influence on that decision.

Before we decided to use Oracle Coherence, we tried out Ehcache, but found the Oracle Coherence better suited our product implementation requirements.
