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 includes software that virtualizes resources. In a nutshell, virtualization is software that separates physical infrastructures to create various dedicated resources. It is the fundamental technology that powers cloud computing. Virtualization software makes it possible to run multiple operating systems and multiple applications on the same server at the same time.
In cloud computing, the virtualized resources are hosted by a service provider or IT department and delivered to users over a network or the Internet.
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. 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.
Amazon Web Services (AWS) – AWS is the market leader in cloud services. Mature capabilities which can be provisioned through their web-based administration console to deploy and maintain secure high-availability web solutions. “Cloud Computing”, by definition, refers to the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing.
Cloud Computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet. Cloud Computing providers such as Amazon Web Services own and maintain the network-connected hardware required for these application services, while you provision and use what you need via a web application.
Summit has partnered with AWS to support cloud computing needs of our clients. Let us share how we have helped clients save over 40% on annual infrastructure cost. We also have extensive experience taking sensitive data (financial, healthcare – HIPPA, personal – SS#, credit card) safely to the public secure cloud.
