Evaluating IaaS and SaaS in the Cloud

Published on 11 March 15

SaaS (Software as a Service) and IaaS (Infrastructure as a Service) are most popular cloud offerings that aid enterprises to save on infrastructure and software costs extensively without compromising on security of your data.

Cloud computing solutions have encompassed IT infrastructure, platforms and software and hence have impacted the IT world in a very large way. The cloud does include even the mails and documents that are uploaded to the web, and nearly means a lot of things to different people. For IT professionals, the cloud offers a cost-effective platform for expanding on their present infrastructure, software and programs. Cloud services are IT components that are delivered to organizations based on their demand. It is also called a pay-as-you-go or subscription basis engagement.

Cloud computing solutions are now being provided by Cloud service providers (CSPs) and nearly every IT element is on offer. These platforms are support structures for setting up development environments with scalable resources. Software services in multitenant architecture, is also on offer for enterprises. Cloud resources, employing a hybrid cloud model are popular too.

Infrastructure as a Service (IaaS) is a cloud model that helps companies to take up computing equipment and resources, including servers, storage, and the like depending on their budget. The providers own and maintain the equipment while renting out services on a "pay as you go" basis.

Platform as a Service (PaaS) on the other hand is a cloud model designed for software developers to shift certain elements of systems management to the service provider. PaaS helps developers to develop mobile applications using pre-configured components and maintained by the service provider.

Software as a Service (SaaS) is the most popular of the cloud applications that are hosted and managed by service providers and available on a subscription basis to those who need it. Most big-shot companies believe that opting for SaaS helps them to avoid overheads in IT infrastructure. With on-premises deployments, and minimal administration of resources, many cases have helped improve communication and collaboration.

Enterprises choose from each of the cloud deployments as per their needs. Those who need an infrastructure, but have volatile needs, opt for IaaS while those who prefer to have an enterprise software, but lack the resources to assimilate it in their IT budget, opt for SaaS. Developers who are concerned about investing in platforms, opt for PaaS and thus avoid shelling out money all at a time for the licenses as well as the entire development environment. With stringent security standards and multiple backups in place, enterprises do not have to worry about loss of data due to unforeseen circumstances. The backup options also help in allaying fears of loss of critical data and its repercussions.

SaaS is a rapidly growing market in every organization. Software as a Service (SaaS) is the most popular cloud hosting & service providers.
