B-Series, a new Azure VM family that provides the lowest cost of any existing size with flexible CPU usage. For many workloads that run in Azure, like web servers, small databases, and development and test environments, the CPU performance is very bursty. These workloads will run for a long time using a small fraction of the CPU performance possible and then spike to needing the full power of the CPU due to incoming traffic or required work. With our current sizes, while running in these low points, you are still paying for the full CPU, so that you can handle the high and bursty points. The B-Series offers a cost effective way to deploy these workloads that do not need the full performance of the CPU continuously and burst in their performance.
