Persistent, highly-secured disk options which support virtual machines
Whether you need the highest availability for mission-critical workloads or cost-effective options for test scenarios, Azure Disk storage gives you the durability, availability and security you need for your virtual machines. Choose Premium Disk storage (SSD) for I/O-intensive applications, where low latency and high throughput are critical. For testing, consider Standard Disk storage (HDD) to keep costs down, as you scale up and down quickly.
Create a managed disk by specifying the type of storage (SSD or HDD) and the size of the disk you need and Azure will create and manage the disk for you.
Highly durable, available and secured
Azure Disks are designed for 99.999% availability. Rest easier knowing that you have three replicas of your data which enables high durability. If one or even two replicas experience issues, the remaining replicas help ensure persistence of your data and high tolerance against failures. This architecture has helped Azure consistently deliver enterprise-grade durability for IaaS disks, with an industry-leading ZERO% Annualised Failure Rate. Plus, your data is automatically secured using encryption at rest.
Why choose Azure Disk storage?
All cloud disk storage is not the same. Azure offers you:
- Certified lift-and-shift—Azure SQL Database, Microsoft Dynamics AX, Microsoft Dynamics CRM, Microsoft Exchange Server and Microsoft SharePoint farms are all certified on Premium Disk storage, so you can count on a fully-integrated deployment solution.
- Cache-enhanced performance—When using Premium Disk storage and DS-series virtual machines, unique caching architecture gives you even lower latency for faster performance.
- Cross platform—Linux support, plus end-to-end integration with trusted Microsoft solutions give you proven options.
Simple scaling on demand
Migrate your on-premises enterprise application to the cloud and walk away from the hardware and infrastructure management. Scale storage up or down with your virtual machine whenever you need to and absorb unexpected spikes in traffic or growth in data storage size. Lift-and-shift your entire infrastructure model—Windows or Linux—and get highly-scalable, globally-available cloud storage.
Low latency and high throughput storage
When performance is critical, you want the low latency and high throughput of Premium Disk storage (SSD). Build your high-performance database with large Azure virtual machines (GS-series) and your users can experience max disk throughput per virtual machine of up to 80,000 IOPS and 2,000 MB per second—and even faster with caching—the kind of speed you need for demanding enterprise workloads.
Support your DevOps goals and test workloads with simple cloud scalability, at a lower cost than on-premises. When you do not need production-level performance, keep persistent data on Standard Disk storage (HDD) and then spin up test virtual machines on demand.
