Whether you need the highest availability for mission-critical workloads or cost-effective options for test scenarios, Azure Disk storage provides 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.
Rest easier knowing that you have three simultaneous replicas of your data, making it more durable and more available. If one replica experiences issues, two others can take over to help ensure persistence of your data and high tolerance against failures. Plus, your data is also automatically secured using encryption at rest.
All cloud disk storage is not the same. Azure offers you:
Migrate your on-premises enterprise application to the cloud, and walk away from all that 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 experience highly-scalable, globally-available cloud 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 don’t need production-level performance, keep persistent data on Standard Disk storage (HDD), then spin up test virtual machines on demand.
