Basv2 sizes series

Basv2-series virtual machines run on the AMD's third Generation EPYC™ 7763v processor in a multi-threaded configuration with up to 256 MB L3 cache configuration. This series provides low cost CPU burstable general purpose virtual machines. Basv2-series virtual machines utilize a CPU credit model to track how much CPU is consumed. The virtual machine accumulates CPU credits when a workload is operating below the base CPU performance threshold and, uses credits when running above the base CPU performance threshold, until all of its credits are consumed. Upon consuming all the CPU credits, a Basv2-series virtual machine is throttled back to its base CPU performance until it accumulates the credits to CPU burst again.

Basv2-series virtual machines offer a balance of compute, memory, and network resources, and are a cost effective way to run a broad spectrum of general purpose workloads. These include large scale micro-services, small and medium databases, virtual desktops, and business-critical applications. This series also offers an affordable option to run your code repositories and dev/test environments. Basv2-Series offers virtual machines of up-to 32 vCPU and 128 Gib of RAM, with max network bandwidth of upto 6,250 Mbps and max uncached disk throughput of 600 Mbps. Basv2-series virtual machines also support attachments of Standard SSD, Standard HDD, Premium SSD disk types with a default Remote-SSD support, you can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines.
