Businesses and individuals rely heavily on technology to store data, run applications, and manage operations. Cloud computing has revolutionized the way we access and utilize computing resources by offering scalable, on-demand services over the Internet. Instead of maintaining expensive physical infrastructure, organizations can leverage cloud-based solutions to improve efficiency, reduce costs, and enhance security.
Here we explore the fundamentals of cloud computing, and its various service models—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—along with their applications, advantages, and limitations. We will also discuss emerging cloud infrastructures such as Database as a Service (DBaaS), Desktop as a Service (DaaS), and Function as a Service (FaaS), helping you understand how to choose the right cloud solutions for your needs.
