What Is Cloud Block Storage

What Is Cloud Block Storage?

Block storage (also known as block-level storage) is the preferred data storage format used by storage area networks (SANs) found in data centers. In block storage, data is stored in blocks where it can be accessed quickly and efficiently by software applications and virtual machines. Cloud block storage is block storage that’s stored in the cloud.

Operating and maintaining your own data center can be costly and time-consuming. As a result, with the advent of cloud storage, many businesses have turned to cloud service providers such as Amazon Web Services (AWS) and Microsoft Azure for their block storage needs.

The Benefits of Cloud Block Storage

Benefits of cloud block storage include:

  • Software defined with consistent data plane
  • Efficient industry-leading data reduction
  • Data mobility eliminates data silos
  • Consistent UX with same APIs on-premises and in the cloud
  • Data resiliency with high availability within and across availability zones
  • Business continuity with synchronized data across availability zones
