CSE Instance Specifications

Microservice engines have professional and exclusive editions.

Professional microservice engine: Cloud Service Engine (CSE) is a free experience engine provided by ServiceStage. You can use a professional engine to experience all product capabilities of ServiceStage, such as service governance and configuration management. Engines are shared by all tenants; however, the performance may be affected by other tenants. A professional engine cannot be upgraded to the exclusive edition.
Exclusive microservice engine: Exclusive engines are commercial engines that manage large-scale microservice applications. You can select different engine specifications based on service requirements, and specifications cannot be changed. Exclusive engines are exclusively used; therefore, the performance is not affected by tenants.

The following describes the maximum number of instances supported by CSE.

**Table 2** CSE Instance Specifications

Professional microservice engine	1,000	-
Exclusive microservice engine	100	600
