Cloud Computing

Cloud Computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. The concept incorporates technologies that have the common theme of reliance on the Internet for satisfying the computing needs of the users. Cloud Computing services usually provide applications online that are accessed from a web browser, while the software and data are stored on the servers.

Companies or individuals engaging in Cloud Computing do not own the physical infrastructure hosting the software platform in question. Instead, they avoid capital expenditure by renting usage from a third-party provider (except for the case of 'Private Cloud' - see below). They consume resources as a service, paying instead for only the resources they use. Many Cloud Computing offerings have adopted the utility computing model, which is analogous to how traditional utilities like electricity are consumed, while others are billed on a subscription basis.

The models that Veeram Infotech offer Cloud Computing solutions, may be layered as: Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS)

The main advantage offered by those solutions is the reduction of infrastructure costs, and of the infrastructure's maintenance. By not owning the hardware and software, Cloud users avoid capital expenditure by renting usage from a third-party provider. Customers pay for only the resources they use. The advantage for the provider of the Cloud, is that sharing computing power among multiple tenants improves utilization rates, as servers are not left idle, which can reduce costs and increase efficiency.
