Some of the types of cloud computing include private clouds, public clouds, hybrid clouds, and multi-clouds. Another common approach to categorizing cloud computing falls into the categories of Software-as-a-Service (SaaS), Platforms-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS). Choosing a type of cloud computing depends on the given needs of the business. They say that No 2 clouds are the same and no 2 cloud services are used to solve the same problem. Let’s take a closer look at Software as a Service, Platform as a Service, and Infrastructure as a Service now.
The types of cloud computing are sometimes represented by a pyramid with three levels. The top of the pyramid is known as Software-as-a-Service, or (SaaS). At this level of the cloud pyramid are products that are run and managed by the service provider entirely. The consumer of the service does not worry about how the service is maintained. It is assumed that the service will be working and available at all times. In all likelihood, you are already a user of a Software-as-a-Service product since some of the most popular applications available today are in fact Software-as-a-Service offerings. These would include things like Salesforce, Gmail, Office 365, and more. SaaS is designed directly for customers. It represents an end-user wanting to use the software as they would on their local device, but in this case, the software is in the cloud and not on the local machine.
At the mid-level of the cloud pyramid is what is known as Platforms-as-a-Service or (PaaS). Platforms-as-a-Service (PaaS) is a type of cloud computing that is designed to support application developers and make their lives easier. In the Platforms-as-a-Service model, the developer can focus on the deployment and management of the applications they want to build. There is no need to worry about provisioning, configuring, or understand the underlying hardware or operating system in use. Three examples of the Platforms-as-a-Service type of computing are Elastic Beanstalk offered by Amazon Web Services, Heroku which is super popular with developers, and Google App Engine.
The foundation of cloud computing is at the bottom level of the cloud pyramid and is known as Infrastructure-as-a-Service or (IaaS). Infrastructure-as-a-Service (IaaS) provides the basic building blocks for cloud-based Information Technology. At this level of cloud computing, administrators are provided access to software-defined networking features, virtual machines for computing power, and different types of data storage applications. With Infrastructure-as-a-Service you don’t worry about the IT staff, data centers, or physical hardware. This is really the most important type of cloud computing since we can’t have Software-as-a-Service applications or Platforms-as-a-Service applications without the foundation level Infrastructure-as-a-Service. The biggest players in cloud computing for Infrastructure-as-a-Service include Microsoft Azure, Amazon Web Services, and Oracle Cloud.
