As it’s known distributed computing is a method of the solution of labor-consuming computing tasks with use of several computers more often integrated in the parallel computing system. Grid и Cloud computing are the form of the distributed computing and represent purely heterogeneous environment

Grid - the coordinated, opened and standardized environment which provides the flexible, safe, coordinated division of resources within the virtual organization.* * Ian Foster, Carl Kesselman “The Anatomy of the Grid”

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.* *NIST Definition of Cloud Computing

 Heterogeneous environment  Using as a common Internet communication environment  There’s an “interoperability problem”

The ability of two or more systems or components to exchange information and to use the information that has been exchanged.* It is reached by means of use of the coordinated sets of IT standards – profiles. *(ISO/IEC FCD24765-Systems and Software Engineering-Vocabulary)

 In the world:  Open Grid Forum (OGF) Standards ( nearly 200 documents)  In Russia:  The first national standard GOST R «Job Submission Description Language (JSDL)» is in the stage of affirming (IRE RAS)  The second national standard GOST R «The Model of the opened Grid environment» is in the stage of development (IRE RAS)

 In the world:  Large number of organizations all over the world working in this field (e.g. The Cloud Computing Interoperability Forum (CCIF) )  In Russia - Mincom svyaz RF :  Federal program « Information society»  Subprogram « National platform for distributed data processing » is developed  The consortium for development of standards is organized

THE CLOUD COMPUTING INTEROPERABILITY FORUM The Cloud Computing Interoperability Forum (CCIF) was formed in order to enable a global cloud computing ecosystem whereby organizations are able to seamlessly work together for the purposes for wider industry adoption of cloud computing technology and related services. A key focus will be placed on the creation of a common agreed upon framework / ontology that enables the ability of two or more cloud platforms to exchange information in an unified manor. Mission CCIF is an open, vendor neutral, not for profit community of technology advocates, and consumers dedicated to driving the rapid adoption of global cloud computing services. CCIF shall accomplish this by working through the use open forums (physical and virtual) focused on building community consensus, exploring emerging trends, and advocating best practices / reference architectures for the purposes of standardized cloud computing.

 Open Grid Forum – 2 standards:  - GFD-P-R183 «Open Сloud Сomputing Interface - СORE»  - GFD-P-R184 «Open Cloud Computing Interface - Infrastructure»  IEEE - 2 standards:  IEEE P2301, Draft Guide for Cloud Portability and Interoperability Profiles  IEEE P2302, Draft Standard for Intercloud Interoperability and Federation

Basic provisions (Framework) Architecture Reference model of interoperability Profile Testing Realization Contain basic provisions on achievement of interoperability. Uniquely identifying of elements of system and communications in between and with environment Development of known reference 7-level model of correlation of open systems (GOST P ). The coordinated set of standards for the reference model of interoperability structured in terms Assessment of compliance of implementation to the standards specified in a profile of interoperability Hardware-software implementation of specific interoperabely system according to an interoperability profile.

 Must contain short descriptions of all above mentinoned stages  Must be affirmed by Mincomsvyaz Cloud4SOA - Objective: CLOUD4SOA focuses on resolving the interoperability and portability issues that exist in current Clouds infrastructures and on introducing a user-centric approach for applications which are built upon and deployed using Cloud resources. To this end, Cloud4SOA aims to combine three fundamental and complementary computing paradigms, namely Cloud computing, Service Oriented Architectures and lightweight semantics to propose a reference architecture and deploy fully operational prototypes.

 Cloud computing is purely a heterogeneous environment  There arises the problem of interaction of its constituent systems, known as "interoperability problem“  Based on a uniform approach it is necessary:  to create the Interoperability Framework  to choose architecture and model  to build profile of standards  standards must be national, but harmonized with international  We invite all interested party for cooperation!
