Infrastructure as a Service lets businesses rent virtualized computing resources instead of buying physical hardware. Companies gain control over virtual machines, storage, and networking while the cloud provider manages the underlying data centers. This model offers flexibility and avoids large upfront capital investments in servers.

In the IAAS model, your team handles operating system management, security patches, and application upgrades. The provider maintains physical servers and networking hardware. This division of responsibility gives you deep customization control, making it ideal for teams needing specific environments without managing the physical facility.

Pricing follows a pay-per-use structure, billing for CPU, memory, and storage consumed. This helps businesses scale resources on demand. A key strategy is Lift and Shift, migrating existing applications from on-premises servers to the cloud without rewriting code, preserving investments while gaining cloud reliability and scalability.
