A-Series
Entry-level VMs for dev/test
百度 呐喊两字写法非常奇特，两个口刻意偏上，还有一个口居下，三个口加起来非常突出，仿佛在齐声呐喊。A-series VMs have CPU performance and memory configurations best suited for entry level workloads like development and test, code repositories etc... They are economical and provide a low-cost option to get started with Azure. Av2 Standard is the latest generation of non-hyperthreaded A-series VMs with similar CPU performance but more RAM per vCPU and faster disks.
