Infrastructure as a Service (IaaS) is a type of cloud computing where you can rent computing resources like servers, storage, networks, and virtualization over the internet. This model is popular because it’s faster and less expensive than buying and setting up your own physical computing hardware.
Usually, when a business needs to run applications or store data, it has to buy and maintain a lot of expensive equipment, find space for it, and hire IT staff to take care of it. This process can be slow, costly, and hard to change if the business grows or needs change suddenly.
With IaaS, you can easily adjust the amount of resources you use to match your needs, avoiding the problems of having too little capacity or wasting money on unused equipment. This flexibility is a big reason why more and more businesses are using IaaS.
Examples of IaaS

AWS is one of the most widely used IaaS platforms. It offers services like Amazon EC2 (Elastic Compute Cloud) for virtual servers, Amazon S3 (Simple Storage Service) for storage, and Amazon VPC (Virtual Private Cloud) for networking.
Microsoft Azure
Azure provides a range of cloud services, including virtual machines, app services, and Azure SQL Database. It’s known for its integration with Microsoft’s software and services.
Oracle Cloud Infrastructure (OCI)
