The term “Standard_b4ms” appears to refer to a specific virtual machine (VM) instance size or type in Microsoft Azure. Azure offers a wide range of VM sizes to cater to different workloads and performance requirements. The “Standard_b4ms” VM size is part of Azure’s “B-series” virtual machines, which are designed for burstable and cost-effective workloads.

Here are some characteristics and details about the “Standard_b4ms” VM size:

1. Family: The “b” in “B-series” indicates that these VMs belong to the Burstable VM family. Burstable VMs are suitable for workloads that have varying CPU utilization, allowing them to burst to higher CPU performance levels when needed.

2. CPU: The “b4” part of the size name suggests that this VM has 4 virtual CPUs (vCPUs). This defines the number of CPU cores available to the VM.

3. Memory: The “ms” part of the size name indicates that this VM comes with a specific amount of memory. The exact amount of memory may vary depending on the specific size, but it is typically in the range of 16 GB to 32 GB.

4. Burstable Performance: B-series VMs in Azure have a unique feature called “burstable performance.” They offer a baseline level of CPU performance and can burst to higher levels for temporary workloads. This makes them cost-effective for workloads that don’t require high CPU utilization at all times.

5. Use Cases: B-series VMs, including “Standard_b4ms,” are suitable for a variety of workloads, including web servers, small databases, development and test environments, and applications with varying compute demands.

6. Pricing: The pricing for “Standard_b4ms” and other B-series VMs is based on the amount of CPU and memory allocated to the VM, as well as the duration of usage. B-series VMs are generally more cost-effective for workloads that can take advantage of burstable CPU performance.
