Introducing B12, B16 & B20 - new larger B-series VM sizes with flexible CPU usage
Published date: July 01, 2019
We have heard our customers asking for larger B-series sizes, and we are excited to share that starting July, we have released three new B-series sizes: B12ms, B16ms and B20ms. These are lower cost VMs with flexible CPU usage.
Target Workloads
As with other B-series offerings, workloads that have ‘peaks and valleys’ usage patterns can take full advantage of the cost savings that these new sizes can offer. Workloads like build servers require 100% CPU utilization when the build is running, and the rest of the time, the servers can run at much lower cpu utilization rate. By using B-series you can keep your build servers cost down and the developers happy. Other workloads include Dev and Test environments and webservers with customer engagement patterns that are subject to burst.
Conversely, B-series VMs would not be a good fit for web servers with consistent login rates. For this type of workload, a D-series virtual machine which offer access to 100% consistent CPU is a better choice.
