Azure Virtual Machines
Azure Virtual Machines (VMs) are software versions of a computer’s hardware on to which we can install Operating System (OS) and the host slices it’s resources across all the VM guests it has running. Microsoft Azure uses as special OS built on Windows Server 2008 Type I hypervisors, called the Microsoft Azure Operating System(OS).
Microsoft Azure Virtual Machines include Windows and Linux VMs, both of which have Basic and Standard tiers. There is a difference between the Basic tier and Standard tier.
- The Basic tier lacks both auto-scaling and load-balancing capabilities. Azure VM sizes are available in both tiers.
- Baes on the required capabilities and configurations are required, use the Standard tier.
- The Standard tier has different Azure VM sizes and divided into series according to their configurations, they are A-series, D-series, DS-series, and G-series.
Azure VM sizes and configurations
Standard tier has different Azure VM sizes and divided into series according to their configurations. Let us learn about each series in detail.
A-series Virtual Machine and Configuration
A-series is a basic, cost-effective and economical. This is used for general purpose for development workload, test servers and other applications.
A-series Basici Azure VM
| Instance | Cores | RAM(GB) | Disk Size (GB) | Price |
| A0 | 1 | 0.75 | 20 | $0.018/hr |
| A1 | 1 | 1.75 | 40 | $0.077/hr |
| A2 | 2 | 3.5 | 60 | $0.154/hr |
| A3 | 4 | 7 | 120 | $0.308/hr |
| A4 | 8 | 14 | 240 | $0.616/hr |
A-Series Standard Virtual Machine.
| Instances | Cores | RAM(GB) | Disk Size (GB) | Price |
| Ao | 1 | 0.75 | 20 | $0.02/hr |
| A1 | 1 | 1.75 | 70 | $0.09/hr |
| A2 | 2 | 3.5 | 135 | $0.18/hr |
| A3 | 4 | 7 | 285 | $0.36/hr |
| A4 | 8 | 14 | 605 | $0.72/hr |
| A5 | 2 | 14 | 135 | $0.33/hr |
| A6 | 4 | 28 | 285 | $0.66/hr |
| A7 | 8 | 56 | 605 | $1.132/hr |
D-Series Virtual Machine and Configurations
D-series VMs should be considered by any business that needs to run applications that demand higher computing power and take advantage of faster disk performance. D-Series Azure Virtual Machine provide faster processors, up to 112 BG of memory, solid state drivers. The virtual cores (vCores) are approximately 60% faster than the A-series and both the local disk and the temporary drive (D:\ on Windows) use a solid-state drive (SSD).
DS-series VMs can use Premium storage, which provides high-performance, low-latency storage for I/O-intensive workloads. These VMs use SSDs to host a VM’s disks and offer a local SSD disk cache.
| Instances | Cores | RAM(GB) | Disk Size (GB) | Price |
| D1 | 1 | 3.5 | 50 | $0.171/hr |
| D2 | 2 | 7 | 100 | $0.342/hr |
| D3 | 4 | 14 | 200 | $0.684/hr |
| D4 | 8 | 28 | 400 | $1.368/hr |
| D11 | 2 | 14 | 100 | $0.403/hr |
| D12 | 4 | 28 | 200 | $0.806/hr |
| D13 | 8 | 56 | 400 | $1.451/hr |
| D14 | 16 | 112 | 800 | $2.611/hr |
G-Series Azure Virtual Machines and Configurations
G-series VMs are the most powerful Azure Virtual Machines and they offer the biggest size and best performance, and they run on hosts with Intel Xeon E5 V3 family processors. These VMs are named for the world’s most famous monster lizard, due to their size.
| Instance | Cores | RAM(GB) | Disk Size (GB) | Price |
| G1 | 2 | 28 | 384 | $0.67/hr |
| G2 | 4 | 56 | 768 | $1.34/hr |
| G3 | 8 | 112 | 1,536 | $2.68/hr |
| G4 | 16 | 224 | 3,072 | $5.36/hr |
| G5 | 32 | 448 | 6,144 | $9.65/hr |
