摘要：Highly-available and scalable web hosting can be a complex and expensive venture. Traditional scalable web architectures have not only needed to implement complex solutions to ensure high levels of reliability, but have also required an accurate forecast of traffic to provide a good quality of service (QoS) to clients. Dense peak traffic periods and wild swings in traffic patterns result in low utilization rates of expensive hardware, yielding high operating costs to maintain idle hardware, as well as an inefficient use of capital for underutilized hardware. As a result, this paper discusses the merits of cloud computing as well as the challenges that could be encountered when hosting computing resources in the cloud.
