As cloud computing has grown in popularity, several different models and deployment strategies have emerged to help meet the needs of different users. Each type of cloud service and deployment method provides you with different levels of control, flexibility, and management.

Understanding the differences between Infrastructure as a ServicePlatform as a Service, and Software as a Service, as well as what deployment strategies you can use will help you decide what set of services are right for your needs.

What's the difference between SaaS, PaaS, and IaaS?

Software as a Service (SaaS)

Software as a Service provides you with a completed product that is run and managed by the service provider. In most cases, people referring to Software as a Service are referring to end-user applications. With a SaaS offering, you do not have to think about how the service is maintained or how the underlying infrastructure is managed; you only need to think about how you will use the software.

A common example of a SaaS application is a web-based email software, such as delivered through Microsoft Office 365, where you can send and receive email without having to manage feature additions to the product or maintain the servers and operating systems that the email program is running on. Another good example is a cloud-based financial solution for which you are free of worrying about upgrades or operating without newly developed features and functions. 

Platform as a Service (PaaS)

Platforms as a service remove the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications. This helps you be more efficient as you don't need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application.  PaaS provides you with computing platforms, which could include the operating system, programming language execution environment, database, web server etc.  An example of a PaaS offering is Microsoft’s Azure SQL Database

Infrastructure as a Service (IaaS)

Organizations looking to develop and deploy custom applications quickly and efficiently, expand their website capabilities, or build a more scalable, responsive database infrastructure, can propel a business forward with Infrastructure as a Service (IaaS). 

Infrastructure as a Service (IaaS), contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space. IaaS provides you with the highest level of flexibility and management control over your IT resources and is most similar to an existing IT resource that many IT departments and developers are familiar with today. Examples of IaaS would include Amazon Web Services’ EC2 and Microsoft’s Azure
