What is PaaS (Platform-as-a-Service)? | IBM
PaaS, or Platform-as-a-Service, is a cloud computing service model that is commonly used alongside Infrastructure-as-a-Service (IaaS) and Software-as-a-Service (SaaS). Organizations often utilize all three models to some extent. IaaS provides internet access to raw IT infrastructure, such as servers, virtual machines, storage, networking, and firewalls, which are hosted by a cloud provider. It eliminates the need for owning and managing on-premises infrastructure, with the organization being responsible for its own application platform and applications.
PaaS offerings inherently include the IaaS resources required for hosting, even if they are not explicitly referred to as such. SaaS, on the other hand, refers to application software that is used via the cloud, simulating local installation on a computer. SaaS allows organizations to use applications without the costs and efforts associated with setting up and maintaining the underlying infrastructure. Examples of popular SaaS offerings include Salesforce and Slack, and most web applications fall under this category.
Each SaaS offering includes the necessary IaaS resources for hosting, as well as, at a minimum, the PaaS components required for running it. Additionally, some SaaS vendors provide a separate PaaS that enables third parties to customize their SaaS offerings.

Use platform as a service (PaaS) options – Azure Architecture Center
Platform as a service (PaaS) and infrastructure as a service (IaaS) are two cloud service models that offer different benefits and functionalities.
IaaS provides access to computing resources such as servers, storage, and networks. The infrastructure is hosted and managed by the IaaS provider, and customers can access these resources over the internet. On the other hand, PaaS offers a framework for developing and running applications. Similar to IaaS, the PaaS provider hosts and maintains the infrastructure, but it also includes additional tools, services, and systems that support the entire web application lifecycle. Developers can leverage the platform to build apps without the need to handle tasks like backups, security solutions, and upgrades.
PaaS has several advantages over IaaS. Using PaaS is like having a pre-assembled product instead of individual parts. It simplifies the configuration and administration process, eliminating the need to set up virtual machines (VMs) or virtual networks. Maintenance tasks such as installing patches and updates are also taken care of. For instance, instead of setting up your own messaging service using RabbitMQ on a VM, you can use Azure Service Bus, which provides a reliable messaging service and is easier to set up. By creating a Service Bus namespace and utilizing a client SDK, you can interact with Service Bus seamlessly.
Although there might be specific requirements where IaaS is more suitable, it is still worth exploring opportunities to incorporate PaaS options. Caches, queues, and data storage are some examples of areas where PaaS alternatives can be used. The provided table showcases additional examples, but it’s important to note that the list is not exhaustive, and there are various ways to replace IaaS technologies with related PaaS solutions.
