Cloud Computing Solutions: IaaS, PaaS, SaaS

By - Source: Toms IT Pro

Cloud computing solutions can include IT infrastructure, development platforms and software. Although "the cloud" can mean a lot of things to different people, for IT professionals it offers a way to extend existing capacity and capabilities. Cloud services are IT components, such as software, programming languages, networking and servers that are delivered to organizations on-demand, usually on a pay-as-you-go or subscription basis.

Cloud computing solutions come in the form of Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Cloud service providers (CSPs) offer organizations utility type resources, like virtual machines, networking and storage capacity. Cloud platforms are support structures that facilitate development environments using pooled and scalable resources. There are also software services that deliver applications using a multitenant architecture. Cloud resources can live both on and off premises, or a combination of both, employing a hybrid cloud model.  

With our IaaS, PaaS and SaaS buyer's guides we help you get started evaluating the top cloud computing solutions by outlining the key considerations as well as the pros, cons and risks that come along with them. Our goal is to streamline the evaluation process by providing an unbiased, analytical look at what the solutions offer and how they can benefit your organization.

IaaS Providers

Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource computing equipment and resources such as servers, storage, networking as well as services, such as load balancing and content delivery networks. The IaaS provider owns and maintains the equipment while the organization rents out the specific services it needs, usually on a "pay as you go" basis.  >> See All IaaS Providers

PaaS Providers

Platform as a Service (PaaS) is a cloud model designed for software developers that streamlines the development process by shifting specific aspects of systems management to the service provider. PaaS is used to develop web and mobile applications using components that are pre-configured and maintained by the service provider, including programming languages, application servers and databases.  >> See All PaaS Providers

SaaS Providers

Software as a Service (SaaS) is a cloud model that delivers on-demand applications that are hosted and managed by the service provider and typically paid for on a subscription basis. SaaS solutions offer a number of advantages over on-premises deployments, including minimal administration and maintenance, anywhere access, and in many cases improved communication and collaboration. >> See All SaaS Providers
