The platform orchestration capabilities use the Symcloud Application Workflow Manager. Applications are deployed using the Symcloud application bundle framework. Using this deployment framework, an application bundle specifies all the resources necessary to deploy an application. When an application bundle is installed, it appears in the application catalog, and platform users can deploy it. The figure below shows the main Symcloud application catalog screen.

When a bundle is deployed, the Symcloud scheduler provisions the required compute, storage, accelerator, and network resources and then starts the application pods. Since the platform is aware of the entire application, the scheduler can use advanced placement techniques, including data locality, data affinity, and infrastructure awareness. During deployment, users can specify deployment and runtime preferences in the launch screen.
The primary component of an application bundle is a manifest file which acts as a blueprint for the application. It describes the application components, any dependencies between services, resource requirements, affinity and anti-affinity rules, and custom actions required for application management. The bundle also contains icons, any supporting scripts, and specifies the necessary container images for the application. Bundles are packaged as compressed tar archives.
Detailed information about the creation and management of applications bundles is available in the Robin Hyperconverged Kubernetes Bundle Building Guide.
Dell Technologies implemented and deployed workload bundles as part of the solution verification process. The following sections describe the implementation of two of these bundles.
