Difference between IAAS, PAAS and SAAS

9 September 2023 0 By Anshul Pal

The cloud is like the internet, where you can store and use stuff online. It’s a big deal for all kinds of businesses, from small ones to huge ones. But it’s a bit confusing because there are many different things you can do in the cloud.

If you’re thinking about using the cloud for your business, there are three main ways to do it:

  • Software as a Service (SaaS).
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)

In this article we breakdown the difference between IAAS, PAAS and SAAS in very simpler and easiest way. Each of these cloud services has its own advantages and differences. We’ll explain what each one is and why you might want to use it. We’ll also help you figure out which one is best for your organization.

SAAS (Software As a Service)

Software as a Service (SaaS) is like using apps on your phone or computer, but they are not on your device. Instead, they are on the internet, and you access them through a web browser. It’s a way to use software and its features from anywhere as long as you have a good internet connection and a web browser. SaaS is also known as “on-demand software“.  SaaS (Software as a Service) is like using apps from the internet to help businesses grow. It’s popular because it’s easy to use and can work for big teams spread out all over the world. You don’t have to install it on every computer; you can just use it online. This is handy when your team is not all in one place.

Advantages & Characteristics of SAAS

SaaS (Software as a Service) is like a time and money saver for both employees and companies. It cuts down the work of installing, handling, and updating software, which can be a real pain. This means technical folks have more time to focus on important things in the company, rather than dealing with software hassles

There are a few ways to help you determine when SaaS is being utilized:

  • Managed from a central location
  • Hosted on a remote server
  • The services are purchased on the pay-as-per-use basis
  • Accessible over the internet
  • Users not responsible for hardware or software updates

Example: BigCommerce, Google Apps, Salesforce, Dropbox, ZenDesk, Cisco WebEx, ZenDesk, Slack, and GoToMeeting.

IASS (Infrastructure As A Service)

IaaS, or infrastructure as a service, is like renting virtual resources from the internet. With IaaS, organizations can get servers, networks, operating systems, and storage without having to buy physical hardware.

Instead of having all the equipment on their premises, IaaS customers store their data on servers provided by IaaS providers. They can control and manage these resources using a dashboard or special software. This way, companies can handle their data needs as they grow, without the hassle of hosting and maintaining physical servers on their own.

IaaS is like the building blocks for creating new technologies in the cloud, and the providers take care of the physical servers around the world where your data is stored.

Example: DigitalOcean, Linode, Amazon Web Services (AWS), Microsoft Azure, Google Compute Engine (GCE), Rackspace, and Cisco Metacloud.

Advantages & Usage of IaaS

  • Scalable: It allows you to quickly increase the computing power for projects that have sudden high demands. This ensures your business can keep running smoothly even during busy periods. This flexibility is especially reassuring when dealing with sensitive data.
  • Customizable: You can design a virtual infrastructure that perfectly suits your requirements. It’s like creating a menu of resources where you can pick and choose what you need.
  • Accessible: Maintaining your own physical infrastructure can be costly. By using a cloud provider for these resources, you can get the same services at a lower cost. This is particularly useful for hosting complex websites, applications, and resource-intensive IT services.
  • Resilient: IaaS can help you create a system for storing and recovering your data, such as backups, in case something goes wrong. Having a disaster recovery plan is crucial for business continuity and ensuring your web applications are always available.
  • AI Development: Artificial intelligence (AI) projects require a lot of resources like computing power, memory, storage, and bandwidth. They involve handling large amounts of data (big data) and training machine learning algorithms. Having additional resources available whenever you need them is a big advantage for your AI projects. It ensures they can run smoothly and efficiently.

PAAS (Platform As A Service)

Platform as a Service (PaaS) is like renting a complete set of tools for building and running applications in the cloud. These tools are managed by someone else, not you. PaaS lets developers create internet-based applications and services. You can choose to use it on the internet (public), within your own organization (private), or a mix of both (hybrid).

Think of PaaS as a service where a third-party provider gives you everything you need to develop and run software, including the software itself and the hardware it runs on. It’s often called Application PaaS because it’s great for organizing and maintaining useful apps and services. PaaS comes with a handy management system, and it’s usually more cost-effective than Infrastructure as a Service (IaaS).

Example: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, Magento Commerce Cloud, and OpenShift.

Characteristics & Usage of PaaS

There are the following characteristics of PaaS –

  • Accessible to various users via the same development application.
  • Integrates with web services and databases.
  • Builds on virtualization technology, so resources can easily be scaled up or down as per the organization’s need.
  • Support multiple languages and frameworks.
  • Provides an ability to “Auto-scale“.

Using Platform as a Service (PaaS) can be really helpful, and in some cases, it’s a must. Here’s why:

  1. Team Collaboration: When many developers are working together on a project, PaaS can make things smoother. It helps in coordinating their work and making sure everyone is on the same page.
  2. Vendor Integration: If you need to bring in other vendors or services into your project, PaaS can speed up the whole process and make it more flexible.
  3. Custom Apps: PaaS is great if you want to create your own specialized applications tailored to your needs.
  4. Cost Savings: It can save you a lot of money, especially when you’re developing or launching an app quickly.
  5. Simplifies Challenges: PaaS can simplify complex challenges that often arise during rapid app development and deployment. It makes things easier to manage.

Differences between IaaS, PaaS & SaaS

IaaS, PaaS, and SaaS are three ways to use cloud technology for your organization. They don’t necessarily compete with each other but instead offer different levels of IT management, giving you alternatives to traditional in-house IT solutions.

In traditional approaches, you’re responsible for managing all your IT infrastructure and software on your own. IaaS, on the other hand, lets you pay for things like storage, networking, and virtualization as you use them, offering a more flexible and cost-effective solution.

PaaS takes it a step further by providing tools for hardware and software development through the internet, reducing the need for in-house development resources.

SaaS offers the highest level of vendor management. It’s like renting complete software solutions, freeing you from the burden of managing the software itself. Each of these cloud models caters to different IT needs and management preferences

In conclusion, the growing adoption of IaaS, PaaS, and SaaS has significantly diminished the necessity for on-premise hosting. As the realms of business and technology become increasingly intertwined, the imperative shift to the cloud becomes apparent for organizations striving to stay at the forefront.
