Language (SoaML): A baseline for Specification of Cloud-based Services

  1. 1. Specifying Services using the Service oriented architecture Modeling Language (SoaML): A baseline for Specification of Cloud-based Services Brian Elvesæter1, Arne-Jørgen Berre1 and Andrey Sadovykh2 1 SINTEF ICT, P.

  2. 2. Outline • Short presentation of the main part of the paper – – – – What is SoaML? Experiences and issues Illustrative example Two approaches • Ongoing and future work – A baseline for Specification of Cloud-based Services – Towards a Cloud Modeling Language (CloudML) SINTEF ICT
  3. 3. What is SoaML? • Service oriented architecture Modeling Language (SoaML) – Defines language constructs and extensions to UML2 to support service concepts (metamodel and UML profile) – Focuses on basic service modelling concepts and structure. – A foundation for further extensions and integration with BPMN, BMM and other metamodels. • Key language constructs – Consumer – MessageType – Participant – Provider – ServiceContract – ServiceInterface – ServicesArchitecture SINTEF ICT 3
  4. 4. SoaML experiences, identified issues and purpose of our paper • Our experiences with SoaML – Tooling – Methods and practices – Application in industry projects • Identified issues – Inconsistencies in the specification. – Two (three) main approaches to service modelling. – Examples illustrating the two approaches are not consistent. – No clear separation, the two approaches are somewhat intertwined. – Tool support lacking or worse wrongly implemented. • Purpose of our paper – Clarify the differences and similarities between the different approaches. – Describe how to align the approaches. – Position SoaML as a baseline for specification of cloud-based services. – SoaML can be extended with new modelling constructs and integrated with other modelling languages.

  9. 9. Cloud computing layers • Cloud computing layers: – – – • Different issues for each layer: – – – – – – – • Software as a Service delivers software as a service over the Internet. Platform as a Service delivers a computing platform and solution stack as a service. Infrastructure as a Service delivers a platform virtualization environment as a service. Security Quality of Service Data Storage Interface Client Application Interface Provisioning Development Platform Virtual machine interface SoaML4Cloud (PIM4Cloud) can’t address all these issues SINTEF ICT 9
  10. 10. Cloud models and languages • We are currently looking at some interesting models and languages: – Amazon Cloudformation • a textual description language for cloud resources • http://aws.amazon.com/cloudformation/ – CA 3Tera AppLogic • a graphical language for Cloud configuration • http://www.ca.com/us/cloud-management-console.aspx – Elastra – with DSLs for Cloud configuration • Elastra Cloud Modeling Language (ECML) is used to describe an application (software, requirements, and policies) • Elastra Deyployment Modeling Language (EDML) is used to describe the resources (virtual machines, storage, and network) available in a data center. • www.elastra.com SINTEF ICT

Future work: OMG standardisation goals • Specify the REMICS SoaML4Cloud (PIM4Cloud) metamodel and profile – – – – extension of the SoaML metamodel and profile platform independent model deployment modelling support for code-generation aimed at cloud computing platforms • Issue an OMG Request for Proposal (RFP) for CloudML – Focus on modelling deployment of applications & services on cloud for portability, interoperability and reuse – Address deployment to Cloud Platforms at the Infrastructure and Service level – Deployment model to specify infrastructure and QoS and SLA properties for analysis SINTEF ICT
