Hello and welcome to the ActiveSpaces blog!
ActiveSpaces is TIBCO's upcoming Data and Messaging Grid product. Technically ActiveSpaces is a distributed in-memory implementation of the Tuplespace concepts.
Hiding beyond this mouthful of technical terms, ActiveSpaces is a fundamental part of the infrastructure that will enable what is described by TIBCO's CEO as the Enterprise 3.0.
A Tuplespace (typically simply referred to as a "Space") can be seen as a form of distributed shared memory: an entity in which data (expressed as Tuples (i.e. 'database rows')) can be concurrently access by multiple processes. Because the data is stored in memory, storage and retrieval of the Tuples is faster than when using a disk-based system. And because it is distributed, it scales according to the number of participants.
ActiveSpaces is a middleware that greatly simplifies the job of Enterprise application developers, providing them with an easy to use interface for data storage and retrieval (Data Grid) and process coordination (Messaging Grid) and allowing them to concentrate on implementing the business logic. Using "Space Based Architecture" (SBA), developers can very easily create distributed, event-driven and scalable (i.e. "Elastic") applications.
