Shifting to cloud computing from traditional sources requires many steps. One of them includes performance monitoring. Cloud storage performance monitoring helps organizations gain visibility into their cloud environments, using specific metrics to assess performance. There are numerous ways to establish metrics and keep track of storage performance. In this article at Computer Weekly, Stephen Pritchard explains how to measure the performance of cloud storage services.
What Should You Measure?
The term ‘IOPS’ refers to input/output operations per second. It measures the ‘read and write’ speed of your storage. It is based on variables such as the configuration of your disk array, sequential or random data patterns, the ratio of ‘read and write’ process, and data block sizes. The IOPS values serve as performance benchmarks for storage devices.
File Storage Performance
You should monitor metrics such as latency, IOPS on storage volumes or services, and storage capacity vs. limits on the storage volume or services. There are two options for managing cloud storage:
- Running virtual machines and attaching block storage volumes to them
- Using managed storage services that includes Azure NetApp Files or Azure Files
As these storage systems interact with applications, they can profoundly impact cloud performance.
Other Storage Metrics
“Most large-scale cloud providers operate a blend of storage hardware, caching, and load-balancing technologies, making raw hardware performance data less useful,” explains Pritchard. Cloud providers also offer different storage formats—block, object, and file—making performance measurements even harder to compare. Therefore, when measuring cloud storage performance, you must consider the types of storage you buy. Also, consider the service-focused offerings, such as backup, recovery, and archiving.
Besides the factors mentioned above, as a buyer of cloud storage, you must also consider data protection, security, and compliance while measuring storage performance. To read the original article, click on https://www.computerweekly.com/feature/Briefing-Cloud-storage-performance-metrics.
