Cloud computing is a process which involves the transfer of data and applications into the cloud. This allows businesses to access them from any place they have internet access. When businesses make the switch to cloud, they can cut out expensive hardware investment and swiftly increase or decrease their infrastructure as needed. This lets companies innovate more easily without waiting for the latest technology blog to arrive.

The most popular way companies use cloud computing is by hosting their applications on a cloud service provider’s servers. This type of cloud computing is called Software-as-a-Service (SaaS). SaaS providers provide all of the hardware, middleware, and application software needed to run a business app within their data centers. They typically provide this service 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). With IaaS companies rent the equipment and storage required to build their own software in a data center managed by the cloud computing provider. It’s similar to renting a home in which you pay only for the rooms that you are using, such as the kitchen during dinner or the bedroom when you go to bed.

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 parts that are activated when they are needed. This lets you pay only for the resources you need.
