What is SaaS, PaaS, and IaaS?

SaaS, PaaS, and IaaS form the fundamentals of cloud computing. When your company has decided to go with the cloud, it is important to understand these three terms. Understanding SaaS, PaaS, and IaaS will help you choose the most appropriate cloud plan for your business.

Cloud is basically a very vast concept and offers different types of services, which can be deployed to suit the business needs. The cloud network usually has three models, Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Let us understand these three terms.

1.Software as a Service (SaaS)

Here the web browsers allow the access to the software hosted on the network/server. One of the most popular models of cloud computing, SaaS allows customers to hire a third party in order to manage the software. If you opt for this model, you save a lot on the cost of software ownership. You do not need to hire a team in-house to manage and update the software. Plus, the cost of licensing the software is also reduced.

Some of the most popular SaaS applications are Google Apps, Salesforce, and Dropbox. These apps are great CRM apps that help businesses to maintain customer relationships.

2.Platform as a Service (PaaS)

PaaS forms the base for SaaS. It basically provides the platform to deploy, develop, and run the software. Customers can take services from PaaS providers who deal with the servers and ensure that customers focus on the business.

PaaS network providers manage hardware and network infrastructure. Hosting platform on the cloud is a smart business decision. It offers the power and freedom to upscale the server any time the business demands. There is no need to invest in unwanted resources. Some of the important PaaS are Heroku, Google App Engine, Force.com, and Apache Stratos.

3.Infrastructure as a Service (IaaS)

This is the base of the cloud fundamentals. It forms the building block of the cloud network and consists of automated systems, storage, and network capability. Customers can take the charge and inform when upscale is required. IaaS is necessary to deploy SaaS and PaaS.

The resources are provided to the authorized people via a dashboard. It is easy to get a virtual data center created by a third-party. The virtual data center offers features of all the features of a traditional data center. With a virtual data center, there is no need to hire an in-house IT team. Plus, it saves the cost of maintenance and capacity planning. Some of the most common examples are Amazon Web Services, Microsoft Azure, and Google Compute Engine.

There are a lot of service providers in the market, who are offering similar services. It is always good to opt for the service provider as it reduces the infrastructure cost. You do not have to install, maintain or update apps and products. Plus, the cost involved in setting up IT infrastructure is eliminated. When there is so much to gain, it is important to hire the best service provider.
