Multi-tenancy is a key feature of Workday and enables multiple customers to share one physical instance of the Workday system in a highly secure environment. Multi-tenancy is enabled through the Workday Object Management Server (OMS). Workday OMS allows servers to host multiple customer tenants simultaneously and builds “security walls” between each of the tenants. Thanks to Workday OMS, there is no way for any worker in one tenant to access the information of another tenant.
Workday delivers its software using a continuous development model. Builds are rolled out weekly that contain new features, bug fixes, or performance improvements. Twice a year, Workday takes all the features put into preview and releases them to production for all customers. Workday customers are never landlocked on an old release, and all customers can utilize new features for the products they purchased as soon as they are live.
