Are there any alternatives to Gigaspaces?

Anything thats as good and as stable and as feature-rich as gigaspaces?

From stackoverflow Marcel

• Gigaspaces is top notch as far as a Javaspaces implementation goes for scalability and performance. Are you restricted to a Javaspaces implementation? Blitz Javaspaces is top notch for a free product.

  From Brad Barker

• As the first answer says, what are your criteria? There's a number of commercial and open-source tools in the same space (but not Javaspaces-based):

  • Oracle Coherence
  • Gemstone's Gemfire
  • Terracotta (a degree of overlap, but not quite in the same space)
  • GridGain (does the grid bit, but not the distributed cache bit)
