The virtualized infrastructure layer lead to software components, such as hypervisors, virtual machines, virtual data storage, and supporting middleware elements required to setup a capable infrastructure to establish efficient computing platform
While virtual machine technology is commonly used at this layer, other means of providing the necessary software abstractions are not precluded. Similarly, the platform architecture layer entails compilers, libraries, utilities, and other software tools and development environments needed to implement applications. The application layer represents deployed software applications targeted towards end-user software clients or other programs, and made available via the cloud.
