Service Models In Cloud Computing

Cloud Computing

In the modern age where science and technology are evolving by the day, and barely any sector is left which is devoid of using computer technology, encourages the youth to incline towards the field of computer science and technology, which has immense demands concerning getting a job in this field with a well renowned international organization.

It has been observed that many computer professionals have been opting for cloud computing courses and have been in search of institutes that offer online courses for cloud computing.

What Are Service Models In Cloud Computing?

Service models in cloud computing issue virtual platforms and tools to design, test and deploy applications. They furnish web software and applications to finish business tasks. The service models aid access to resources like virtual machines and virtual storage in cloud computing. Runtime habitat and stationing tools for applications are provided by cloud computing.

The three types of cloud service models are as follows:
● Infrastructure as a service ( IaaS)
● Platform as a service (PaaS)
● Software as a service ( SaaS)
All these three aspects are Fundamentals of cloud computing.

Infrastructure As A Service ( IaaS)

It is a computing substructure supervised over the internet. It is also known as hardware as a service (HaaS). The chief benefit of using IaaS is that it aids users in circumventing the cost and complication of buying and managing the physical servers. The (IaaS) Infrastructure as a service is a cloud computing presentation where a vendor grants access to the users to computing resources such as storage, networking, and servers. Companies may use their platforms and applications within a service provider’s infrastructure.

Attributes Of IaaS

● Resources are accessible as a service
● Services are extremely scalable
● Dynamic and pliable
● GUI and API based access
● Saves a lot of money for the company to buy and maintain their hardware.
● Automated administrative tasks.
● As data is available on the cloud, points of failure are negligible.
● Users pay only for IaaS on demand instead of buying hardware outright.

The common examples where IaaS is used are Amazon web series (AWS), Microsoft Azure, and Google Compute Engine (GCE), to name a few.

Platform As A Service (PaaS)

The platform developed for the programmer to develop, test run, and manage the applications is Platform as a service (PaaS). The Platform as a service (PaaS) is a cloud computing presentation that provides users with a cloud environment where they can supervise, create and deliver applications. Along with the storage and various computing resources, the users can also utilize a suite of predefined tools to create, alter and test their applications.

Development organizations or companies that want to introduce dexterous organizing systems are best suited for PaaS. PaaS providers furnish various services which can be utilized for many applications. The services will always be available and up to date. PaaS paves a very straightforward way to test and master model new applications. A lot of monetary savings can be achieved during the development of new services and applications. User feedback can be retrieved early as the applications are released early.

Attributes Of PaaS

● Approachable by many users through the same development application.
● No worries of underlying structure to the organizations so they can focus on their development.
● The PaaS provides a platform with tools to test, create and host applications in the same environment.
● Combines with web services and databases.
● Collaborative work is facilitated though teams are working remotely.
● Sets on virtual technology, so resources may be easily scaled up or down as per the company’s need.
● Subsidizes various languages and frameworks.
● Auto Scaling ability is facilitated.

The common examples are Windows Azure,, Google App Engine, Apache Stratos, and Openshift, among many.

Software As A Service (SaaS)

The software where the applications are hosted by a cloud service provider is called a SaaS. It is also known as On-demand software. With the help of an internet connection and a web browser, the applications can be easily accessed by the user. The software as a service (SaaS) is cloud computing, giving users access to a vendor’s cloud-based software. The users are not required to install the applications on their local devices. Rather, the applications are present on the remote cloud network accessed via the web or an API. Using the application, the users can store and analyze data and collaborate on projects.

Attributes Of SaaS

  • SaaS can be managed from a central location
  • It can be hosted on a remote server
  • It is accessible over the internet and can be retrieved by any device connecting it to the internet.
  • It is updated automatically, and hence the users need not bother about updating it.
  • The services needed may be purchased as per the usage and necessity.
  • Failure of equipment does not affect the loss of data as the data is safe in the cloud.
  • The utilization of resources can be scaled as per their needs.

The common examples are Google Apps, Dropbox, Zendesk, Slack, and BigCommerce.

In renowned organizations utilizing software technologies, it is up to the administrators how to make use of every infrastructure available with regards to the hardware and software. Usually, it may consume time for a user regarding access to a  new resource, but it can be prepared exactly as required.

Conventional infrastructure is mostly with core applications that cannot be swiftly diverted to cloud paradigms. There may be more reasons required to shift to the cloud other than standardization and flexibility, which should be the companies ultimate call. Country-by-laws often urge users to place data near or under total management control.


We arrive at a conclusion where it is obvious that service models such as the IaaS, PaaS, and SaaS have been proved worthy and have helped inefficient working of an organization and thus accepted by leading companies globally. The various innovations in the field of computer technology have seen students opting for more computer-related Cloud courses as they provide them with an upper hand in various fields related to data science which include being a data scientist, data modeling, etc.
