Scalaris is a scalable and fault-tolerant structured storage with strong data consistency for online databases or Web 2.0 services.
Without system interruption it scales from a few PCs to thousands of servers. According to the demands, add or take away computers from a production system at anytime without risking any service downtime. Scalaris does all the rest: fail-over, data distribution, load-balancing, replication, strong consistency, and transactions.
I ran into this during a marathon most of the night research session last night on a number of topics related to scalability, concurrent programming, and message passing systems architecture. I was impressed. This is not lightweight reading and I will definitely have to go over it again to fully grok. But, I'm excited about some possibilities a system like this might enable.
And that is the news for now...
