A Secure Hybrid Cloud Infrastructure for Scientific Applications

Salman Toor
DescriptionThe cloud paradigm allows building a scalable computational and storage infrastructure for a variety of applications. Currently most of cloud platforms are based in a single datacenter facility. This model serves well as it allows efficient resource management and security. However the model of building large computational islands still requires communication and coordination between them.

The DII-HEP private cloud, based on the OpenStack cloud suite and the Gluster file system, is designed to provide a scalable and secure private infrastructure for scientific applications. The infrastructure is evaluated with the Compact Muon Solenoid (CMS) data analysis framework, a highly challenging scientific application that requires computational, storage and network resources. For handling security issues, we have used the Host Identity Protocol (HIP). The HIP approach is portable (vendor agnostic), tenant oriented and thus can be deployed in any IaaS cloud. In DII-HEP, the HIP based security layer provides bases for building a secure multi-tenant and hybrid environment
