Cloud Computing


The Cloud Computing paradigm is rapidly transforming the development, deployment, and management of Information Systems on a basic level. Cloud technologies, such as virtualization, application containers, multi-cloud federation and the Intercloud are enabling elasticity, cost-efficiency and scalability for private deployments as well as public offerings.


SNET is conducting applied research oriented towards the needs of business, academic, and private cloud consumers. Some of our research areas include: 

  • The description and brokering of cloud services using simple domain-specific languages.
  • Cloud brokering and matchmaking using constraint modelling.
  • Secure federated multi-cloud access management using standards such as OpenID Connect, SAML, and XACML.
  • Attribute-based encryption technologies for personal data sharing
  • Cloud location information and metadata structures.

We always try to publish Open Source software in our Github repository.
