Portable Cloud Services Using TOSCA

Platform : java

IEEE Projects Years : 2012 - 13

Portable Cloud Services Using TOSCA

For cloud services to be portable, their management must also be portable to the targeted environment, as must the application components themselves. Here, the authors show how plans in the Topology and Orchestration Specification for Cloud Applications (TOSCA) can enable portability of these operational aspects underneath all the hype, the essence of cloud computing is the industrialization of IT. Similar to mass production lines in other industries (such as the auto industry), cloud computing standardizes offered services and thus increases automation significantly. Consequently, enterprises are increasingly utilizing cloud technology; however, major challenges such as portability, standardization of service definitions, and security remain inadequately addressed. The ability to move cloud services and their components between providers ensures an adequate and cost-efficient IT environment and avoids vendor lock-in. Research has already addressed movability and migration on a functional level.1,2 However, no one has yet examined cloud service portability with regard to management and operational tasks, which are a significant and increasing cost factor. One reason is the lack of an industry standard for defining composite applications and their management. Without an appropriate standardized format, ensuring compliance, trust, and security the biggest area of critique preventing the cloud’s wider adoption is difficult. Dealing with these challenges in industry and research has the potential to bring cloud computing to the next level.

TOSCA will enable the interoperable description of application and infrastructure cloud services, the relationships between parts of the service, and the operational behavior of these services (e.g., deploy, patch, shutdown)--independent of the supplier creating the service, and any particular cloud provider or hosting technology. TOSCA will also make it possible for higher-level operational behavior to be associated with cloud infrastructure management.

EXISTING SYSTEM:

            In the existing system portability, standardization of service definitions and security remain inadequately addressed. The ability to move cloud services and their components between providers ensures an adequate and cost-efficient IT environment and avoids vendor lock-in. The movability and migration on function level with regard to management and operational tasks, which are a significant and increasing cost factor.

Disadvantages:

1)Portability, standardization of  service definitions, and security is not effective in existing system.

2) the industry standard for defining composite applications is not efficient  .

PROPOSED SYSTEM:

             In the offering phase, the cloud service provider creates a cloud service offering based on a service template, adding all provider- and offering-specific information. This includes aspects such as pricing and specific technical information such as IP address range and application configurations. Finally, the offering is published in a service catalog. In the subscription and instantiation phase, the cloud service consumer browsing the service catalog can select and subscribe to the respective offering. The consumer customizes the service through points of variability (for example, selecting “small,” “medium,” or “large” for the service’s size), signs a contract, and accepts the offering’s terms and conditions. This subscription process triggers the instantiation of the cloud service instance. The cloud management platform aggregates all the required resources from the common resource pools, for example infrastructure components, and automatically deploys, installs, and configures the service’s necessary pieces.

 

Advantages:

 

1) the management aspects of cloud services in a reusable way.

2) use existing workflow technologies and research results to facilitate the portable, automated, and reusable management of cloud services throughout their life cycle.
