What is Multitenancy?

• Multitenancy is a reference to the mode of operation of software where multiple

independent instances of one or multiple applications operate in a shared environment.

• The instances (tenants) are logically isolated, with single JVM. The degree of logical

isolation must be complete, but the degree of physical integration will vary.
