We need various types of software for our work, but we cannot purchase them due to their high cost. SaaS, one of the models of Cloud Computing Services, offers you the perfect solution. You can now access any software just by paying the subscription fee, and there is no need to purchase the software as they are expensive. One of the features of Saas is that they host the software in the cloud.

You can access it only after paying the requisite fee, just like using something on rent. Hence, you save much money by purchasing the software. Moreover, installing the software onto your hard drive is optional. Therefore, it also eliminates the requirement of purchasing extra storage space in your computer.

The following are the key characteristics of SaaS.

  • SaaS is operated from one central location, giving access to various software types.
  • Since SaaS is hosted from a remote server, you can easily access it with an internet connection.
  • You do not have to worry about software and hardware updates as they are taken care of from the central location.

Advantages of using SaaS

FAQ About SaaS vs. PaaS vs. IaaS

SaaS is for any users as they can access the software of their choice by paying a certain amount of fee as a subscription. However, PaaS is only for application developers, and you will get all the necessary tools to develop your application without worrying about software and hardware installation.

If we only consider costs, SaaS is the least expensive cloud computing service out of the three, followed by PaaS and IaaS.

The best Cloud Computing model for Mobile App Development companies is PaaS (Platform as a Service). It is because you will get all the tools necessary to build your app. Moreover, you will also be able to test your app on various platforms.

If you want to hire developers to develop a perfect app for your company, then it is advisable to use the services of PaaS. It will offer you the latest tools to help smooth and fast app development.

The third cloud computing provider, AWS, is a hybrid of the three services. For the purpose of providing its services, it combines SaaS, PaaS, and IaaS.

Businesses that want to control their data and physical assets should consider IaaS. However, a lot of management is required. Developers and systems that concentrate on developing product features benefit greatly from PaaS. The PaaS model is easier to operate and less expensive than the IaaS model, but it has fewer scalability options. Despite its high scalability and reasonable price, IaaS has some difficulties in terms of maintenance.
