Hybrid, multi-Cloud deployment most cost-effective

Hybrid or multi-Cloud deployment is the most cost-effective and efficient method for a business to manage abundant Cloud computing resources, according to Cloud computing experts from the University of Sydney.

The School of Information Technologies’ Centre for distributed and high performance computing has endorsed the hybrid Cloud model because it is a “scalable, quantifiable solution that can combine the best of both private and public Clouds.”

Private Cloud capacity can be reduced by dynamically provisioning public Cloud capacity. While sensitive data and time critical workloads are processed in their private Cloud, the rest may be offloaded to public Clouds.

“A hybrid Cloud is a Cloud computing environment where a business can manage some resources in-house while also utilising external providers,” a researcher from the Centre, Young Choon Lee, said. “A business or organisation might use a public Cloud service such as Amazon EC2m MS Azure or Google Compute Engine to process and archive burly data, but continue to utilise its in-house storage for operational or day to day data.”

“The hybrid approach allows a business to take advantage of the scalability and cost-effectiveness that a public Cloud computing environment offers without exposing the organisation’s applications and data to third-party vulnerabilities such as hacking.”

In addition, the trade- off between cost and performance that are two main and conflicting objectives in hybrid Cloud can be effectively captured using pareto-optimality, Lee said.

According to the University of Sydney’s chair of high performance computing and networking, Professor Albert Zomaya, it is critical we develop models for the efficient use of Cloud resources and traditional datacentres.
