Abstract
With the emergence and quick development of cloud computing, both enterprises and individuals enjoy the cost advantage brought by pay-as-you-go model and efficiency which virtualization technology provides. As the bandwidth, storage and computing resources can be consumed in a utility fashion, the industry and the ways of living are anticipated to be greatly revolutionized.
While cloud computing yields new opportunities, challenges arise. Data security concern and lack of service level agreements (SLAs) are preventing organizations from adopting cloud services from external vendors. In this context, hybrid cloud seems to evolve as the next big opportunity for combining the advantage of private cloud’s direct control on sensitive data and that of public cloud’s low cost.
As hybrid cloud begins to be seen as a solution, the optimal ratio of private and public cloud becomes an issue. We term a strategy of how much percentage should go for private while the rest go for public as “hybrid-cloud architecture”. Based on our performance model, we focus on Infrastructure as a Service (IaaS) category and conduct cost-effective analysis under different hybrid-cloud architectures. Taking into consideration different levels of security requirement and service response time as SLAs, we give customized suggestions on the optimal hybrid-cloud architecture for organizations with various characteristics and requirements.
