Is Terracotta a kind of reliable alternative to JVMs?

Question

I come across Terracotta as a distributed JVM that is stable and robust, however as my understanding of Terracotta is shallow, i am not sure if Terracotta is an alternative to JVMs?

It looks promising.

Answer 1

Terracotta is not a JVM, it's a shared memory backplane. It does not replace the JVM in any way. Terracotta now owns and makes several projects which can leverage this backplane.

They include

• Ehcache
• Sessions
• Quartz

Amongst others. Their product BigMemory also helps to overcome some of the JVM Heap issues with very large allocations.
