Storage as a service (STaaS) is a data storage business model where a provider delivers capacity and performance resources through a simple subscription with service-level agreements (SLAs). STaaS provides the ultimate in agility and simplicity—the storage is managed for you, and you only pay for the storage you need, when you need it.

A flexible ownership subscription combines features of a traditional storage purchase with an as-a-Service subscription. Similar to a traditional purchase, the storage is purchased and maintained by the user. And like an as-a-Service subscription, the user pays via the subscription for only the storage used. This unique consumption model allows for lower upfront costs and better asset utilization for organizations that need to maintain ownership of their IT infrastructure based on regulatory needs or preference.

The Evergreen architecture was designed by Pure Storage to enable continuous upgrades of storage controllers and flash without downtime or uninterrupted access to critical applications and workloads.

Storage management encompasses all the processes and technologies used to manage the resources, software, and hardware that make up a data storage system. It involves striking the optimal balance between costs, performance, and capacity while ensuring the availability, resiliency, and security of the data that powers an increasingly digital world.
