Platform as a Service (PaaS)

The great leap of cloud computing is based on the "Platform as a Service", a software layer that automatically manages the mega-datacenter.

The first generation of cloud, limited to the lowest layer also known as Infrastructure as a Service (IaaS) is the simple evolution of hosting and virtualization. E 'can be used directly by application software classical server-definable como certrici, but to achieve the reliability and scalability required by SaaS applications, you need to add complex middleware to distribute the workload across different servers to move the load from those failures, etc.. This increases the complexity and cost, without completely solve the problems.

Modern applications such as aKite, developed in a "platform-centric", have the enormous advantage of drastically solve a variety of complex problems and systems theory to focus on the delivery of services to eleveta scalability and service level (SLA). The possibility into using resources depending on the time of day, day of week and time of year, reduces costs and more environmentally.
