Primary storage systems for large enterprises have adapted quickly to new needs and business requirements, with data now accessed from both on-premises and cloud applications.
We're in a transition phase, moving from storage systems designed to be deployed in data centers to hybrid and multicloud solutions, with similar functionalities provided on physical or virtual appliances, as well as through managed services.
The concepts of primary storage, data, and workloads have radically changed over the past few years. Mission- and business-critical functions in enterprise organizations used to be concentrated in a few monolithic applications based on traditional relational databases. In that scenario, block storage was often synonymous with primary storage, and performance, availability, and resiliency were prioritized, usually at the expense of flexibility, ease of use, and low cost.
