A cloud computing environment may have a landscape space for singleton applications including a SAAS UAA component to receive a subscription request associated with a user and a platform SAAS application. A user system registry may indicate spaces in which the user is registered, a route proxy agent may route communications via a first secure communication channel in accordance with information in the user system registry, and a route service broker may handle binding requests. The environment may also include a first system space for first system microservices with a first system onboarding application that receives provisioning application information via the route proxy agent and the secure communication channel. First backend microservices may similarly receive application router information, and a first route service shared instance clone may provide binding requests to the route service broker. A second system space for second system microservices may similarly be provided.
