New D-Series Virtual Machines for Azure

On the last week of Sepetember, Microsoft has released new set of VM sizes for Microsoft Azure which are ideal for many compute and data-intensive research applications. According to the official announcement the new D-Series VMs are 40-60% faster than other series.

Faster processors (approximately 60% faster than our A series), more memory(up to 112 GB) and SSD hard drives(up to 800 GB) are the key attraction in D-Series of VM. Companies/organizations that run “big data and analytics” or “data-intensive-type applications” are the main target .This D-Series VM can be used with both Azure Virtual Machines and Azure Cloud Services.

To start using the new D-Series VM sizes jump to the current Azure Management Portal or Preview Portal. You can also use Azure management command-line/scripts/APIs for this purpose.

Note: Local SSDs with D-Series are “not guaranteed to be persistent,” meaning that the data “may be lost” if there’s a hardware failure. So, the SSDs are best used with “workloads that replicate across multiple instances,” such as MongoDB.

This is also a perfect candidate for database management solutions that can handle a high-input/output disk as a “local and temporary cache,” such as the “buffer pool extension” feature in SQL Server 2014.
