Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for upgrading a software platform. One of the methods includes receiving, by a platform orchestrator, a request to upgrade computing resources of a software platform launched by the platform orchestrator, wherein a workload having multiple different software tasks is executing on multiple nodes of the software platform launched by the platform orchestrator; obtaining, by the platform orchestrator, a workload specification that specifies an upgrade ordering among multiple groups of the multiple software tasks executing on the software platform; and upgrading, by the platform orchestrator, all platform nodes that execute one or more software tasks in a first group of the multiple groups of software tasks before upgrading platform nodes that execute one or more software tasks in a second group of the multiple groups of software tasks, according to the upgrade ordering specified in the workload specification.

Abstract: Methods, systems, and computer readable media for creating segmented virtual networks for service instances. A method includes receiving, by a system controller, a user request requesting creation of a service instance in a software platform system hosting a plurality of service instances. The system controller provides, to a service broker proxy, a request to provision resources for the requested service instance. The service broker proxy creates a new virtual network for the requested service instance. The service broker proxy provides one or more cloud configuration parameters of the new virtual network to a deployment manager that provisions resources in an underlying cloud computing infrastructure. The service broker proxy provides, to an on-demand service broker, a request to provision computing resources in the underlying cloud computing infrastructure to implement the service instance having the one or more cloud configuration parameters.
