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.
