Iaas Vs Paas Vs Saas Meaning, Examples, Differences


A platform that virtualizes hardware and organizes those resources into clouds. Managed services are a way to offload general tasks to an expert, in order to reduce costs, improve service quality, or free internal teams to do work that’s specific to your business. Public cloud providers such as AWS, Microsoft Azure, and Google Cloud are examples of IaaS. One way to use IaaS would be as a quick, flexible way to build up and take down and development and testing environments. If you are looking for a highly flexible, scalable service — while maintaining control of its infrastructure — then IaaS is the right choice for you. If you need a platform designed for building software products, then PaaS would help your business immediately.

Instead of buying physical hardware, you can rent the infrastructure you need as a virtual service through an IaaS vendor. On-premise IT infrastructure presents the biggest level of responsibility to you as a user and manager. When your hardware and software are all on-premises, it’s up to you and your team to manage, update, and replace each component as needed. What cloud computing allows for is the allocation of one, several, or all of the parts of your infrastructure to the management of a third party, freeing you up to focus on other things. Each cloud service model offers different features and functionalities. SaaS is delivered through the internet as a full functional service, accessible via any web browser.

Platform-as-a-service is another step further from full, on-premise infrastructure management. Let’s start by breaking down commonality within the acroynyms. “As-a-service” generally means a cloud computing service that is provided by a third party so that you can focus on what’s more important to you, like your code and relationships with your customers. Each type of cloud computing leaves you less and less on-premise infrastructure to manage.

It’s important to note, that since moving to the cloud is a hard, resource-consuming process, it’s key to prepare the application accordingly ahead of time. The process of making the product ready for the switch may include dealing with technical debt, that earlier was put aside. For starters, moving from one vendor to another can be challenging because not all SaaS apps follow open pros and cons of paas standards for integration. The primary differences of SaaS, PaaS, and IaaS stem from what the vendor manages and what the end-user manages. SaaS makes updating conventional business software a breeze. You can enjoy effortless customization with simple point-and-click steps and align your application with your evolving business needs without modifying the app’s core functionality.

Many organizations require deep integrations with on-premise apps, data, and services. The SaaS vendor may offer limited support in this regard, forcing organizations to invest internal resources in designing and managing integrations. The complexity of integrations can further limit how the SaaS app or other dependent services can be used. Similarly, PaaS comes with pre-built platform that may include pre-installed OS and services which you can populate with your data and applications.
