This chapter describes different aspects of CUBA applications deployment and operation.

The diagram below shows possible structure of a deployed application.

In the example above, the application prevents a single point of failure existence, provides load balancing and various client types connection. In the simplest case, however, the server part of an application can be installed on one computer that includes the database. Various deployment options depending on load and fault tolerance requirements are described in detail in Section 6.3, “Application Scaling”.
