Cloud Infrastructure Market - Private Cloud & Hybrid Cloud, Backup, Disaster Management

Cloud computing is an innovation for data storage. It generally consists of three services software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Cloud computing is growing due to increasing expense in ICT spending and trend of big data and analytics. Cloud infrastructure refers to the software and hardware components such as networking, storage, servers, and virtualization software that are required for a cloud computing model to operate. Cloud infrastructure also includes an abstraction layer of software that virtualizes resources and presents them to the users in a programmatic manner. Virtualized resources are hosted such as an IT department or service providers and delivered to the final user through the medium of a network or internet. These virtualized resources include virtual machines which have components such as memory, computer, servers, firewall, network switches, storage, and load balancers. In cloud computing architecture (that refers to the back end and front end of the whole cloud computing environment), the cloud infrastructure generally includes the back end components.
