Amazon EC2 instances, the Google Compute Engine, and Microsoft Azure VMs are all examples of _____.

Amazon EC2 instances, Google Compute Engine, and Microsoft Azure VMs are all classified as Infrastructure as a Service (IaaS) because they provide virtualized computing resources over the internet. This model allows users to rent virtual machines and storage without the need to manage the underlying hardware.

With IaaS, customers have more control over the infrastructure compared to other service models. They can configure the virtual machines in various ways, choose their operating systems, and install software as needed. This flexibility makes IaaS a popular choice for businesses that want to scale their infrastructure easily and efficiently.

In contrast, Platform as a Service (PaaS) focuses on providing a platform allowing developers to build, deploy, and manage applications without dealing with the underlying hardware and operating systems. Software as a Service (SaaS) delivers software applications over the internet, eliminating the need for installation and maintenance on individual devices. Function as a Service (FaaS), often referred to as serverless computing, allows users to run code without managing servers, focusing instead on the execution of functions in response to events.

In summary, the correct classification of EC2, Google Compute Engine, and Azure VMs as Infrastructure as a Service reflects their nature as foundational computing resources
