Introduction

Most businesses in the present era are gradually transferring their entire infrastructure into the cloud. It is because you can access your documents from around the world. The traditional storage of files and documents has become a part of our history books. It is because there is a massive transition in digital technology. So, if you are also keen on transferring all your data to the cloud, you need reasonable knowledge about its various services.

Hence, it is a requirement that before you use any of the cloud services, you must have explicit knowledge of the features and usability of IaaS vs. PaaS vs. SaaS. It will help you to choose a suitable model for your business.

What is Cloud Computing?

Cloud computing has changed the entire traditional infrastructure of computing. Install large servers, storage devices, and software is not required. You can store everything in the cloud. Moreover, it is safe and secure, bypassing all the hassles of computer crashes, software upgrades, and similar technical obstacles. You can store your data in the cloud and retrieve it conveniently.

However, it would be best if you had a proper internet connection to access your data from the cloud. It is so flexible that you can retrieve or upload data from your Android phone. Hence, Cloud Computing plays a dominant role in bringing about a change in our computing infrastructure.

Cloud Computing Model

Types of Cloud Computing Services

1. Software as a Service (SaaS)

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.

Characteristics of SaaS

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

  • Reduces your time: The primary advantage of using SaaS is that since the software is already in the remote server, you can access them at your convenience by paying some fee as a subscription. Hence, you do not need to spend time installing the software as it provides ready-to-use software and updates.
  • Cost-effective: One of the primary reasons users and businesses are moving towards the services provided by SaaS is because they can access the software of their choice within their budget. There is no need to spend considerable money on purchasing the software.

Frequently Asked Questions (FAQs)

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.
