Introduction to Cloud Computing
Cloud computing has profoundly transformed the way businesses and individuals use technology. It refers to the delivery of various services over the internet, including data storage, servers, databases, networking, and software. Cloud computing’s roots trace back to the 1960s, but it wasn’t until the early 2000s that it gained significant momentum. Today, it stands as a cornerstone of the modern digital era, offering scalability, efficiency, and cost-effective solutions to its users.
Understanding Cloud Computing Models
Infrastructure as a Service (IaaS)
IaaS provides fundamental computing infrastructure like virtualized hardware, network, and storage over the internet. It offers a high level of flexibility and control over IT resources.
Platform as a Service (PaaS)
PaaS delivers hardware and software tools over the internet, generally for application development. It simplifies the process by handling underlying infrastructure.
Software as a Service (SaaS)
SaaS provides software applications over the internet on a subscription basis. It eliminates the need for installations and maintenance, offering easy accessibility.
