The EGI Federated Cloud is a new kind of research e-infrastructure designed to serve the scientific community. In support of this mission, the EGI has contributed to a report on service level agreements and also provided hands-on training.
Researchers from the Suddhananda Engineering and Research Centre in Bhubaneswar, India developed a job scheduling system, which they call Service Level Agreement (SLA) scheduling, that is meant to achieve acceptable methods of resource provisioning similar to that of potential in-house systems. They combined that with an on-demand resource provisioner to ensure utilization optimization of virtual machines.
Some might look beyond SLAs to ensure their data is protected–and covered.
This in-depth article by Dr. Ivona Brandic notes that while a wealth of work has been accomplished to suit the technological development of clouds, there has yet been very little work done in the area of the market mechanisms that support them.
Service Level Agreement (SLA) mapping is a relatively new concept designed to standardize the way users find and use cloud service providers–and create the necessary environment for dynamic and open cloud markets.
Gartner released its report of Infrastructure as a Service (IaaS) providers for the year, placing Amazon Web Services at the bottom of the tiered list.
Service Level Agreements (SLAs) are crucial to any nontrivial use of the cloud. Once an organization understands its requirements, it needs a guarantee from its cloud provider that those requirements will be met. Cloud consumers trust cloud providers to deliver some or all of their infrastructure services, so it is vital to define what those services are, how they are delivered and how they are used.
Ian Foster says supercomputers may be faster, but clouds may be nimbler.
