CLARUS follows an interoperability by design approach by investigating the use of open standards in the architecture design and in the implementation of the CLARUS components. One of the CLARUS objectives is to implement standards supported by a wide range of Cloud Service Providers (CSPs) and end users, thereby ensuring interoperability in collaborative, standardised and transparent cloud environments.
By implementing a set of standardized cloud services transparent with regard to data management, privacy and security, CLARUS will achieve interoperability between otherwise heterogeneous cloud providers and CLARUS proxies, installed in the end-user trusted domain. Collaborative services (e.g., edition of documents outsourced to the cloud by several users) can be implemented through several CLARUS proxies and APIs based on standards can be made available to programmers for a seamless development of end-user cloud-based applications.
Interoperability ensures that the actors and systems providing cloud computing services and implementing the CLARUS solution exchange and make use of the information. Interoperability also reduces the risk of vendor lock-in for customers, which is one of the major obstacles to the adoption of cloud computing along with legal issues related to data protection and security, all aspects addressed by the CLARUS solution.
Interoperability brings several benefits to CLARUS such as the possibility of implementing more robust security mechanisms and improving reliability and dependability, while increasing transparency and trust in cloud services. CLARUS considers interoperability in different domains.
- Application Programming Interfaces (APIs) of the components and tools developed as part of the CLARUS solution.
- Security solutions to secure the communications, authenticate the users, and provide access to CLARUS cloud services.
- Data and metadata stored and processed by CLARUS. In the context of the two CLARUS use cases: the Open Geospatial Consortium standards for the publication of geo-referenced data on the Internet, and the Health Level-7 standard for the transfer and format of healthcare information.
