Choosing the Right Cloud Service Model for Your Business

In the evolving landscape of cloud computing, selecting the right service model is crucial for the success and efficiency of your business operations. This article explores the three primary cloud service models – Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) – to help you make an informed decision tailored to your business needs.

Software as a Service (SaaS):

  • What is SaaS? Delivers software applications over the internet, accessible through a web browser.
