AWS & MS Public Cloud Storage steps up to next level

“Last week, Microsoft announced the general availability of Azure Premium Storage, the choice of storage for demanding workloads. A week before that, at the AWS Summit, Amazon has launched a new storage type on the public cloud called Elastic File System. Both these announcements have a positive impact on the public cloud adoption.”

Amazon Elastic File System (EFS) is the latest addition to the AWS storage offerings. The new service provides multiple EC2 instances with low-latency, shared access to a fully-managed file system. According to AWS, Elastic File System provides elastic capacity that automatically grows and shrinks as the files are added and removed. Based on the standard NFSv4 protocol, the file system is accessible from both Microsoft Windows and Linux operating systems. Since the file system is available as a multi-tenant, shared service, Amazon is backing it up with SSD-based storage. The data is replicated across multiple availability zones for redundancy and high availability. The service integrates with Amazon’s security model based on Identity and Access Management (IAM) and VPC security groups. Administrators can use standard file and directory permissions to control access to the file system.”

Azure Premium Storage
When moving enterprise workloads to the cloud, customers want the performance to match their existing environment. One of the most visible drawbacks of cloud migration is the drop in the I/O performance. In the last few years, public cloud providers attempted to address this by moving to Solid State Drives or SSDs. Though SSD-based storage is expensive than the standard magnetic disk-based storage, customers prefer to run a set of workloads on them. Microsoft Azure Premium Storage promises to offer best-in-class public cloud storage for enterprise workloads.”

Premium Storage needs to be attached to Azure DS Series VMs in the form of a Page Blob or Data Disk. Customers can attach multiple disks to a VM to get up to 32 TB of storage per VM with more than 64,000 IOPS per VM.”

“With the right configuration, VMs can reach 50,000 IOPS, which is considered to be the best performance on the public cloud. The below screenshot of a benchmarking tool shows a VM achieving 100,000 IOPs of performance.
