Rubrik Multi-tenancy: Secure Data Isolation for a True Cloud Computing Era

Multi-tenancy is one of the cornerstones of a cloud data management platform. It enables you to support multiple customers (commonly referred to as ‘tenants’) on a single platform. Pooling resources results in lower costs, greater efficiencies, and faster innovation for both tenants and service providers. Secure data and metadata isolation is required in multi-tenant environments. Traditionally, data isolation required for multi-tenant environments is established as physical boundaries. The storage domain, including its compute resources, is divided into multiple partitions, and role-based access control is applied on those partitions, as shown above. Each tenant is given a rigid partition isolated from others using physical boundaries. The resources are often over-provisioned to meet tenant demand during peak usage. Thus, resources are often underutilized and typically wasted. The security principals (user and service accounts) need to be reserved for each partition. Rubrik brings an innovative cloud-based framework for secure data and metadata isolation. This is designed to give the best of both worlds; security benefits of physical boundaries and economic advantages of a true cloud computing model. It is made possible by virtualizing all resources so that tenants can share allocated resources in a secure, isolated fashion, as pictured above. Let’s take a…
