Today we are announcing the general availability (GA) of two new instances for use with Windows Azure Cloud Services. Called A8 and A9, they feature 8 virtual cores with 56 gigabytes (GB) and 16 virtual cores with 112 GB of memory, respectively. A8 and A9 belong to a new category of instances called compute-intensive instances that provide faster processors and more virtual cores for higher compute power, larger amounts of memory, and a 40 Gbit/s InfiniBand network that includes remote direct memory access (RDMA) technology for maximum efficiency of parallel Message Passing Interface (MPI) applications. Compute-intensive instances are optimal for running compute and network-intensive applications such as high-performance cluster applications, applications using modeling, simulation and analysis, and video encoding. Please consider using the new A8 and A9 instances for running your compute and network-intensive applications.
