Cloud computing is a process which involves the transfer of applications and data into the cloud. This allows businesses to access them from any place they have internet access. When businesses move to the cloud, they are able to eliminate expensive hardware investment and swiftly scale up or down infrastructure depending on the requirements. This allows businesses to develop faster without having to wait for new technology.

Enterprises benefit from the cloud the mostly by hosting their applications on the servers of cloud service providers. This type of cloud computing is called Software-as-a-Service (SaaS). SaaS providers host all of the middleware, hardware, and application software required to run enterprise apps in their data centers. This service is typically offered on a pay-as-you go basis, which means that the user only pays for what they use.

Another popular cloud service is called Infrastructure-as-a-Service (IaaS). IaaS lets a business rent the hardware and storage required for its own application in a cloud computing service’s data center. It’s similar to renting a home where you only pay for the rooms you use, like the kitchen area when you eat dinner or the bedroom when you’re sleeping.

Finally, a newer cloud service called Function-as-a-Service (FaaS) is emerging that offers even more scalability and agility for business users. FaaS breaks down cloud applications into small pieces that are only activated when required. This lets you pay only for the resources you need.
