IaaS

A cloud computing model that delivers fundamental IT resources—such as virtual servers, storage, and networking—on demand over the internet. Instead of purchasing and maintaining physical hardware, organizations can rent computing infrastructure from a cloud provider and pay only for what they use.

IaaS provides the foundational layer of the cloud stack, giving businesses full control over their operating systems, applications, and configurations while outsourcing the physical infrastructure and data center management. This approach allows teams to scale resources dynamically, optimize costs, and deploy new environments in minutes rather than weeks.

Typical IaaS services include virtual machines, block and object storage, load balancing, and security management. Leading providers such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and DigitalOcean enable enterprises to run workloads globally without investing in on-premise servers.

IaaS offers flexibility, scalability, and reliability for organizations building cloud-native applications, running legacy systems, or powering DevOps pipelines—making it a critical component of modern cloud infrastructure.
