Every time a customer loads up a homepage or starts to stream a movie, there are a number of microservices involved to complete that request. Most of

by Adrian Cockcroft Today AWS has launched a new Solid State Disk (SSD) based instance that addresses the need for high performance I/O, and we have run a few initial benchmarks to see how it shapes up. With this announcement AWS makes it easy to provision extremely high I/O capacity with consistently low latency. AWS has been competitive in instance memory capacity for a long time and is leading
