Cloud Infrastructure refers to the collection of hardware and software components that support the delivery of cloud services. This includes servers, storage systems, networking equipment, and virtualization technologies. These components work together to provide scalable and flexible resources that can be accessed over the internet. Organizations use Cloud Infrastructure to host applications, store data, and manage workloads without needing to invest in physical hardware. This approach allows for easier maintenance, cost savings, and the ability to quickly adapt to changing business needs. Popular providers of Cloud Infrastructure include Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
