FAQ
In simple language, What is
1. Cloud Computing
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computer resources (e.g., networks, servers, storage, applications, and services) that do not require end user knowledge of specific physical location and configuration details. These resources are provided as a utility over a virtualized infrastructure, with consumption billed based on usage.
2. Virtualization
Virtualization is the creation of a fully functional system without regard to physical hardware. A virtual machine (VM) is a software implementation of a physical machine running its own operating system. VMs allow a single host computer to run multiple isolated environments called guests. Each guest operates completely independent of the others.
3. Infrastructure as a Service (IaaS)
Infrastructure as a Service (Iaas) is a cloud computing model where users buy compute time rather than buying or renting equipment. IaaS providers offer resizable compute capacity at relatively low cost per hour.
4. Platform as a Service (PaaS)
Platform as a Service (Pas) provides tools and frameworks to developers to build, deploy, and manage web apps. PaaS providers provide ready-to-run platforms similar to those included in traditional desktop operating systems.
5. Software as a Service (Saas)
Software as a Service (SaaS) is a type of application software where the application runs on a third party's server instead of the client's computer. SaaS providers deliver hosted solutions via the Internet.
6. Utility Computing
Utility computing is a business model where consumers pay only for what they use. In contrast to the traditional purchase of fixed assets, utility computing involves paying for each unit of computation performed. Consumers may choose between different levels of service, ranging from basic performance guarantees to unlimited usage.
7. Data Center
A data center is a facility housing computers and associated components, such as telecommunications switches and routers, network devices, power supplies, environmental controls, and backup generators. Data centers have been used since the early 1970s, when the first commercial data centers were built. Today, many companies rely heavily on their data centers to store critical information.
