We employ best practices to design and build better applications with the unique characteristics, limitations and opportunities of a cloud model in mind.
The advent of the Cloud has made it possible to build SaaS Cloud computing applications in entirely new ways such that the application is cognizant of the underlying infrastructure and can take intelligent scaling decisions based on business metrics or on the state of the application. Applications built this way can better harness the elasticity, fault-tolerance and cost savings offered by the cloud.
