- Volley: Automated Data Placement for Geo-Distributed Cloud Services. Murat Demirbas with great coverage on a paper by Microsoft Research on a heuristic strategy for data placement to geo-distributed datacenters. The evaluations show that Volley converged after a small number of iterations, and reduced skew by 2x, inter-datacenter traffic by 1.8x, and latency by 30%.
- Death match! EBS versus SSD price, performance, and QoS. Baron Schwartz with ring side commentary finding in a knock-down-drag-out fight between the EBS gang and the SSD thugs, a small number of SSDs mops the floor with the competition, and walks away with the prize.

- In a world where algorithms are for people who don't know how to buy RAM, isn't 24 Gigabytes of Memory Ought to be Enough for Anybody? Jeff Atwood observes: To me, it's more about no longer needing to think about memory as a scarce resource, something you allocate carefully and manage with great care. There's just .. lots.

- Baron Schwartz runs some benchmarks to test Is VoltDB really as scalable as they claim? The answer is yes: I’ll tell you: scaling a synchronously replicated, active-active master, fully ACID, always-consistent database to a 40-server cluster is impressive.
