SINGLE, LOGICAL, MULTI-TIER APPLICATION BLUEPRINT USED FOR DEPLOYMENT AND MANAGEMENT OF MULTIPLE PHYSICAL APPLICATIONS IN A CLOUD INFRASTRUCTURE

A deployment system enables a developer to define a logical, multi-tier application blueprint that can be used to create and manage (e.g., redeploy, upgrade, backup, patch) multiple applications in a cloud infrastructure. In the application blueprint, the developer models an overall application architecture, or topology, that includes individual and clustered nodes (e.g., VMs), logical templates, cloud providers, deployment environments, software services, application-specific code, properties, and dependencies between top-tier and second-tier components. The application can be deployed according to the application blueprint, which means any needed VMs are provisioned from the cloud infrastructure, and application components and software services are installed.
