cloud Based Infrastructure

cloud Based Infrastructure - Cloud computing has evolved through a number of phases which include grid and utility computing, application service provision (ASP), and Software as a Service (SaaS). Cloud computing has evolved through a number of phases which include grid and utility computing, application service provision (ASP), and Software as a Service (SaaS). But the overarching concept of delivering computing resources through a global network is rooted in the sixties. Cloud computing offers your business many benefits. It allows you to set up what is essentially a virtual office to give you the flexibility of connecting to your business anywhere, any time. With the growing number of web-enabled devices used in today's business environment (e.g. smartphones, tablets), access to your data is even easier.

Cloud infrastructure refers to the hardware and software components -- such as servers, storage, networking and virtualization software -- that are needed to support the computing requirements of a cloud computing model. In addition, cloud infrastructures include a software abstraction layer that virtualizes resources and logically presents them to users through programmatic means.

In cloud computing, virtualized resources are hosted by a service provider or IT department and delivered to users over a network or the Internet. These resources include virtual machines and components such as servers, compute, memory, network switches, firewalls, load balancers and storage. In a cloud computing architecture, which refers to the front end and back end of a cloud computing environment, cloud infrastructure consists of the back end components.

Cloud infrastructure is present in each of the three main cloud computing models, infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Together, these three models form what's often called a cloud computing stack, with IaaS as the foundation, PaaS as the middle layer, and SaaS as the top layer. Businesses use cloud infrastructures to run their applications. Unlike subscription-based pricing models, or payment structures that enable users to subscribe to vendor services for a set price, cloud infrastructures are typically purchased using a pay-per-use model. In a pay-per-usage model, users only pay for the services consumed generally on an hourly, weekly or monthly basis.

Rather than purchase cloud infrastructure from a provider, businesses can also build cloud infrastructures on-premises. When cloud providers maintain the cloud infrastructure, the environment is a public cloud. When the organization using cloud maintains the cloud infrastructure, the environment is a private cloud. And when both the cloud provider and user own pieces of the cloud infrastructure, the environment is a hybrid cloud.
