    Unified Invocation of Scripts and Services for Provisioning, Deployment, and Management of Cloud Applications Based on TOSCA

    There are several script-centric approaches, APIs, and tools available to implement automated provisioning, deployment, and management of applications in the cloud. The automation of all these aspects is key for reducing costs. However, most of these approaches are script-centric and provide proprietary solutions employing different invocation mechanisms, interfaces, and state...

    Combining Declarative and Imperative Cloud Application Provisioning based on TOSCA

    The automation of application provisioning is one of the most important issues in cloud computing. The Topology and Orchestration Specification for Cloud Applications (TOSCA) supports automating provisioning by two different flavors: declarative processing is based on interpreting application topology models by a runtime that infers provisioning logic whereas imperative processing...
