What is SaaS, PaaS. IaaS & How to choose?
If you’re considering moving your e-commerce business to the Cloud, here are three important acronyms to wrap your head around SaaS, PaaS, and IaaS
SaaS, PaaS, and IaaS are simply three ways to describe how you can use the cloud for your business.
1) Infrastructure as a Service (IaaS) is the on-demand delivery of computing resources over the internet, including networking, storage, and other infrastructural components. A category of cloud computing, IaaS relieves users of the need to maintain physical servers while also providing them the flexibility to provision and scale their resources as needed

2) Platform as a Service (PaaS) is a category of cloud computing in which developers can provision deployment platforms to build applications. The underlying infrastructure of each platform is abstracted, meaning that users can expect pre-configured runtime environments and predictable scaling, storage, and security options. Users also have access to languages, libraries, tools, and services for application development, as well as a certain degree of control over configuration settings. However, they do not have the ability to modify the underlying operating system or network settings
3) Software as a Service (SaaS) is a category of cloud computing in which software is provided as a product over the internet. With SaaS, users have access to software provided by third-party vendors, though they are not in charge of the production, maintenance, or modification of that software. SaaS abstracts away the software application’s underlying infrastructure so that users are only exposed to the interface they interact with.
