Multi-Tenancy: A Concept Whose Time Has Come and (Almost) Gone

摘要

With the emergence of server-less computing the need for multi-tenancy in application services diminishes and eventually disappears as server-less computing supports the isolation between tenants by cloud account automatically. A server-less application installed into a customer's cloud account is isolated from other customer's cloud accounts by means of the underlying cloud provider infrastructure automatically. Aside from perfect partitioning in all aspects, this server-less computing simplifies the implementation of an application service since multi-tenancy does not have to be implemented or managed at all by the application service logic itself. The position brought forward in this paper is that the concept of multi-tenancy for application design and implementation is obsolete in context of application services implemented based on server-less computing.
