In Layman’s Terms

“As a Service” refers to cloud computing services that deliver various computing resources and software over the internet. Instead of buying and maintaining physical hardware and software, you access these resources online and pay based on usage. It’s like subscribing to a service where you use what you need and leave the rest to the service provider.

In Technical Terms

“As a Service” (XaaS) is a collective term for various services provided over the internet. It encompasses models like Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). These services are managed by third-party providers who handle the infrastructure, maintenance, and updates.
