The Zen v15 database is available in three major engine types, the Workgroup Engine, the Enterprise Server Engine, and the Cloud Server. The Workgroup Engine is designed for single-user installations and small workgroups of up to 5 concurrent users. The Enterprise Server Engine is designed for servers hosting 6 or more users, and it is available for Windows (32-bit and 64-bit) or Linux (64-bit) servers. The Cloud Server product is identical in functionality to the Enterprise Server, but it uses a license model based on data size instead of user count (and therefore allows for an unlimited number of users). Cloud Server licenses are required for environments using middleware, web servers, or SaaS environments, but otherwise, either license type may be selected.
Note that the two server-class engines offer improved performance and security, in addition to running as a true 64-bit component on the server.
Licenses are available in either "base" licenses, of which you can have only one on any given server, and user count increase (UCI) licenses, which can be used to increase your concurrent user count. Special Insurance licenses are available to provide protection from downtime in the event of a licensing or server failure.
For the Enterprise Server Engine base licenses, upgrade discounts may be available depending on your source engine version and user count.
