The “Standard_B2s” is a specific virtual machine (VM) instance size in Microsoft Azure. Azure offers a variety of VM sizes to cater to different workloads and performance requirements. The “Standard_B2s” VM size belongs to the “B-series” family of VMs in Azure, which are designed for burstable and cost-effective workloads. Here are some key details about the “Standard_B2s” VM size:

1. Family: The “B” in “B-series” stands for Burstable, indicating that these VMs are suitable for workloads with varying CPU utilization. B-series VMs provide a baseline level of CPU performance and can burst to higher CPU performance levels when needed.

2. CPU: The “2” in “B2s” indicates that this VM has 2 virtual CPUs (vCPUs). This defines the number of CPU cores available to the VM.

3. Memory: B-series VMs come with a varying amount of memory depending on the specific size within the family. While the exact amount of memory may vary, it is typically in the range of 4 GB to 8 GB for “Standard_B2s.”

4. Burstable Performance: B-series VMs are known for their burstable performance capability. They offer a baseline level of CPU performance and can burst to higher performance levels when the workload demands it. This makes them cost-effective for workloads that do not require high CPU utilization all the time.

5. Use Cases: “Standard_B2s” and other B-series VMs are suitable for a range of workloads, including web servers, small databases, development and test environments, and applications with varying compute requirements.

6. Pricing: The pricing for “Standard_B2s” and other B-series VMs is based on the allocated CPU, memory, and the duration of usage. B-series VMs are cost-effective for workloads that can benefit from burstable CPU performance.
