IaaS vs PaaS vs SaaS: What’s The Difference?

There is no denying that cloud services are a hot topic. The cloud is a uniquely modern phenomenon, allowing software and services to be stored remotely across the internet instead of just in one place. It’s important for businesses because it allows information that requires large amounts of space on an individual device to now exist anywhere virtually.

Cloud computing uses a network of different servers hosting data online – involving the process of storing, managing, and processing information on these remote sites often referred to as “the cloud”. IaaS, PaaS, and SaaS are the three main categories of cloud computing services. Cloud-based software and services can be accessed on any internet browser, allowing you to get a job done anywhere. Let’s delve a little deeper.

What is IaaS (Infrastructure As a Service)


The IaaS products help an organization manage its business resources on the cloud – networks, servers, and data storage are all managed remotely.


IaaS products deliver storage systems, networks, and servers virtually to enterprise businesses. Organizations can access data through either a dashboard or create their own native dashboards then connect them with providers’ API (application programming interface) for easy management anywhere in the world.


  1. The most realistic way to adapt your company services for a continually connected workforce
  2. Enables rapid scalability with lower costs than other options
  3. Allows flexibility, as businesses only pay for the resources they need
  4. Organizations have full control over their infrastructure
  5. It can be scaled as per the user’s need
  6. An organization do not need to buy or maintain a physical server


  1. It is an organization’s responsibility for being “technologically” secure
  2. You’re in charge of the data — if any of it is lost, you will need to recover itB
  3. IaaS providers offer a server and API but you’ll need to do all configuration on your end.

IaaS Examples

  • Amazon Web Services (AWS)
  • Cisco Metapod
  • Microsoft Azure
  • Google Compute Engine (GCE)

What is PaaS (Platform As a Service)


PaaS products allow businesses and developers to host, build, and deploy consumer-facing apps without the hassle of buying hardware or managing servers.


PaaS creates a secure platform where developers can create software and apps for consumer use. Developers have the opportunity to access PaaS tools over the web.


  1. Developers build their app right on the platform and deploy it immediately
  2. Cost-effective and allows easy collaboration among an entire team
  3. PaaS tools are easy to sign up for and user friendly
  4. Through a single application, developers can connect, across the globe
  5. No software upkeep on the backend
  6. Provide scalability and flexibility, as the apps grow in usage


  1. An outage or issue with the operating system will take out any software built on top of that platform as well
  2. You only have control over coding and not infrastructure
  3. Your data is stored by your PaaS provider, thus possessing a security risk to all the users of your apps
  4. The deployment process is limited by the PaaS terms of service, so customization on your end isn’t extensive

PaaS Examples

  1. AWS Elastic Beanstalk
  2. Windows Azure
  3. Heroku
  4. Google App Engine

What is SaaS (Software As a Service) 


The most popular cloud service is SaaS. This type of product offers both consumers and businesses a range of convenient tools for everyday use.


With a SaaS app, there’s no need for a specialist to come in and manually install it on each laptop using a purchased license. You just get an internet connection and enjoy the perks of these valuable tools that are constantly being updated with new features – all at your fingertips!


  1. Doesn’t require local hosting
  2. Software management and up-gradation is included in subscription or purchase
  3. Do not use your local resources, like, space on your physical server
  4. Good SaaS software are easy to locate and purchase
  5. The upkeep of SaaS software is not your responsibility


  1. You can’t mitigate an outage or slow down
  2. Your business can be impacted by widespread website outages or other technical problems with the software
  3. SaaS tools might not work with other tools and hardware that are already in use at your business
  4. Your SaaS provider takes care of software’s integration and you won’t be able to patch any integration issues
  5. Any kind of security breach at the service provider’s end puts all your and your customer data exposed

SaaS Examples

  1. Google Workspace
  2. Salesforce
  3. ZapERP
  4. Cisco WebEx
