Differences Between SaaS, IaaS, PaaS in Cloud Computing?

Cloud technology is starting to take place more and more in our lives every day. Cloud computing, which has started to replace desktop computer applications in recent years, is frequently researched. Cloud computing, the importance of which is much better understood during the Covid-19 pandemic period, enables every company or company, regardless of size, to access information technologies from anywhere with internet. Cloud computing services are also divided into three as SaaS, IaaS and PaaS . In this article, we have examined all these for you.

What is SaaS (Software as a Service)?

SaaS, or Software as a Service , is known as the most widely used option for companies working with cloud-based computing. This cloud computing option acts as an intermediary in third party applications managed by a vendor. That is, it uses the internet to present these applications to the users. This application is performed directly through your web browser . SaaS does not require any installation. In this way, it manages technical problems well and provides simplified maintenance and support to the business. 

SaaS provides many benefits to users. It eliminates extremely tedious processes such as software installation, management, upgrade. It saves both time and money. In addition, it also eases the workload of technical personnel to deal with tasks such as software installation, and it becomes easier to respond to emergencies more quickly. 

SaaS Features

It is managed from a central location. 

It is hosted on a remote server. 

It is easily accessible over the internet. 

The Users are not responsible for software or hardware.

What is IaaS (Infrastructure as a Service)?

IaaS, aka Infrastructure as a Service, is done through scalable and automated computing resources. Also known as a self-service, IaaS is used to access computers, networks, storage, other services. In addition, monitoring of these services is done by IaaS. With IaaS, businesses don't buy hardware. Instead, they buy resources that are demanded and needed. This makes a great contribution to the parties. 

The IaaS deliver cloud computing infrastructure including these servers like, operating systems, network and storage through virtualization technology. These cloud servers, available via the dashboard or API , give IaaS customers full control. Offering the same technologies as traditional data centers, IaaS does this without the need for physical protection and monitoring. IaaS clients can gain direct access to their servers and repositories. Also known as the most flexible computing model, IaaS is a cloud system technology that is highly scalable, easy to automate, and provides full control.

IaaS Features

Cost varies depending on consumption. 

Services are scalable. 

The organization is under full control of the infrastructure. 

It has a dynamic and flexible structure.

What is PaaS (Platform as a Service)?

PaaS, also known as Platform as a Service, is mainly used for applications. It also provides cloud components for certain software. It provides an opportunity for developers to create specially customized applications. With PaaS, developers have a framework specifically designed to develop or modify their applications. PaaS also enables rapid and cost-effective development and testing of applications. Developers are freed from some difficulties such as setting up and managing the basic infrastructure of network, storage, server, databases required to develop web or mobile applications. 

PaaS enables costs to be drastically reduced. Since it is easy to use, it also eliminates factors such as difficulty in use. No skill required. You don't need to be an expert. Multiple developers can thus work on the same project. This greatly increases cooperation.

PaaS Features

PaaS is a system built on virtualization technology. Resources are easily scalable. 

It offers many different possibilities for developing or modifying applications. 

It is accessible to many users. 

It integrates web services and databases.

What are the Differences Between SaaS, IaaS, PaaS in Cloud Computing?

We learned the basics of SaaS, IaaS, PaaS . Now, there are the differences between these three IT services. These three different types of cloud software offer many different advantages. 

IaaS is also known as a very new business model, especially for hosting companies. This model works with the idea of ​​purchasing resources as needed. PaaS i provides a framework for developers. SaaS, unlike these, allows companies to offer software interfaces to users. 

PaaS is mostly used by application developers. IaaS is mostly preferred by network architects. 

PaaS is known as a cloud computing category where service providers offer a computing platform. IaaS , on the other hand, works more focused on providing computer infrastructure.

The purpose of the IaaS model is to create IT equipment , the purpose of the SaaS model is to provide easy access to the application whenever and wherever they want, and the purpose of the PaaS model is to prepare the test environment for software developers.
