The Difference Between SaaS and PaaS

As the cloud continues to be a hot topic of discussion for small businesses and large enterprises alike, businesses are realizing that the cloud is a complex, offering a variety of services outside of just storage.

There are underlying platforms, otherwise considered technologies, that offer unique ways for businesses to expedite product development, outsource work, etc. When it comes to the world of software and the cloud market, the four main platforms are as follows: Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), Infrastructure-as-a-Service (IaaS), and Nothing-as-a-Service (NaaS). The two that we want to focus on here are SaaS and PaaS, as they hold the most relevance to businesses today.

The service that best fits you and your business will depend on the size of your business, as well as the structure of your business. You will also need to decide how much work you wish to manage yourself, and how much work you are looking to outsource to the provider of the service.

SaaS: Software as a Service
SaaS is the most commonly used option for businesses in the cloud market. SaaS exploits the internet as a means to deliver applications to the end user. These applications are being managed by a third-party vendor. This prevents the user from having to download or install any applications necessary because they are being run straight through the web browser. This saves the user a substantial amount of time and money that would otherwise be spent on managing the software.

– The third-party vendor manages all of the following: applications, data, runtime, middleware, O/S, virtualization, servers, storage, and networking.

– Examples of SaaS: Google Apps, DropBox, Salesforce, Cisco WebEx, and GoToMeeting

PaaS: Platform as a Service
In contrast to how SaaS delivers software for users over the internet, PaaS provides a platform where users can create, customize, and develop their own software. The third-party vendor manages the servers, storage, and networking and the user, or developer, takes responsibility for managing the applications themselves. It also provides for scalability, high availability, automation of business policy, easy migration to the hybrid model, and various other advantages.

– The third-party vendor manages all of the following: Runtime, middleware, O/S, virtualization, servers, storage, and networking.

– Examples of PaaS: AWS Elastic Beanstalk, Windows Azure, Heroku,, Google App Engine, Apache Stratos, and OpenShift
