Building Scalable Architectures For Web Applications in Cloud.

      Аннотация: This book presents, detailed review on style of building cloud architectures for web-applications to attain scalability, reliability and high- availability in real time. Highly-available and scalable web hosting can be a difficult and costly proposition. Traditional scalable web architectures have not only needed to implement difficult solutions to ensure high levels of reliability, but have also needed an exact forecast of traffic to provide a high level of customer service. 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. Cloud computing provides the reliable, scalable, secure, and highly performing infrastructure required for the most demanding web applications, while enabling an elastic, scale-out and scale-down infrastructure model to match IT costs with real-time customer traffic patterns. However, we cannot leverage all that scalability in infrastructure if our architecture is not scalable. Both have to work together.
