I didn't think The Register did Editorials? What's happened guys? The joy has been leeched out. Biting the hand that feeds IT? Not for the past couple of months.
To bring a little balance to this.
Check out :-
* SAP Hana/ as mentioned. My review - too expensive, IDE is awful, obsessed with a database
* Gemfire/ Apache Geode. Geode (open source) lags Gemfire slightly due to it recently open sourcing. A very nice product otherwise. Lots of use in finance, it's first niche (eg, fraud detection stuff)
* Hazelcast - Good history, has always been open source and so has overall greater adoption than gemfire. nice integration with jvm collections.
* Coherence - not sure where this is up to now ... It's oracle. I can't bring myself to bite down on their contractuals.
* Terracotta - Was the hot thing 4 years ago in this space. The model didn't seem to catch on. It's more focused on being able to address a theoretically infinitely large JVM heap space. Different to the others in that they give access via a particular API, whereas terracotta appears to be local memory.
So, there we go.
