The basic idea is the outsourcing of infrastructure, application servers, disk space, databases, etc., instead of having a full administrative load with the data center within the company or the option of a data center and its management. With an infrastructure as a Service (IAAS), what you have is a solution based on virtualization or dedicated hardware, in which you pay for the use of resources: storage, database space, data transfer, RAM memory.

The most immediate advantage of choosing this type of solution is to transfer to the vendor a number of problems related to hardware administration, electricity, cooling equipment, electrical backup drives, etc. Overall, we achieve large savings in costs by paying only for what was consumed and make most of the economies of scale. In addition, we know that infrastructure as a service can enable automatic or semiautomatic scalability, so that we can hire more resources, as we need them.
