B-series update: B1ls is now available
Published date: 01 April, 2019
We are excited to announce a new B-series VM size, B1ls, which has the smallest memory and lowest cost among Azure VM instances. This offering is in response to customers who were looking for entry-level offerings. B1ls has 512 MiB of memory and 1 vCPU and it costs only $0.0052 (US East) per hour.
Target workloads
B1ls is best for small web servers, small databases and development and test environments. It offers a cost-effective way to deploy workloads that don't need the full performance of the CPU continuously and burst in their performance.
Performance
B1ls is available only on Linux for the best customer experience. Windows is not supported because the minimum recommended memory for the Windows OS is larger than what B1ls offers.
