Cloud computing is the process of moving data and applications to the cloud, allowing companies to access them from any location with an internet connection. Businesses can save money by switching to cloud computing and scaling their infrastructure up or down as required. This enables businesses to innovate faster without having to wait for new technology.

Enterprises utilize the cloud mostly by hosting their applications on the servers of a cloud service provider. This type of cloud computing is called Software-as-a-Service (SaaS). SaaS providers provide all the hardware, middleware and application software required to run an enterprise application in their data centers. They typically offer this service on a pay-as you-go basis, which means that customers only pay for the services they utilize.

Another popular cloud service is called Infrastructure-as-a-Service (IaaS). IaaS allows a company to rent the hardware and storage required to build its own applications in a cloud computing service’s data center. It’s similar to renting a house where you only pay for the rooms that you use, such as the kitchen when you have dinner or the bedroom before 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 smaller pieces that are only activated when required. This lets you pay only for the resources you require.
