Integrating GigaSpaces persistency service into an existing tier based system
April 23rd, 2008A common issue I’m facing recently is how to integrate existing tier based applications with GigaSpaces persistency service, AKA persistency as a service (Paas) or mirror . The motivation is often a result of the acknowledgment that a standard tier based application fails to scale when facing the database throughput limitation.
Software Caching technologies (overlooking their [...]
Sharing Results of Expensive Computations

When it comes to [...]

It reminds me of the discussions I use to have when I used Versant as an object database and object store in the late 90s. Object Graphs assume a certain hierarchy [...]

SBA and J2EE Positioning Clarification
March 20th, 2007When people first hear about Space-Based Architecture (SBA) one of their immediate reactions is - "Is it a replacement for J2EE?" Since J2EE is not necessarily only one thing (especially not today with all the recent developments in the likes of Spring, POJO's etc.) my answer is that SBA is both compatible with as well [...]
