Abstract: A tenant multiplexer in an administrative tenant of a multi-tenant software architecture can call an administrative agent in the administrative tenant and receive, from the administrative agent, an action framework and a trusted connection protocol for accessing each of the plurality of client tenants. The trusted connection protocol can establish, without tenant-specific authentication information, a trusted system connection to an update agent in each of the plurality of client tenants. An action framework can be simultaneously implemented using the update agent of each of at least a subset of the plurality of client tenants under control of the multiplexer via the trusted system connection to begin execution of the software process for the at least the subset of client tenants.
