Cloud computing is a method that involves moving applications and data to the cloud. This lets businesses access their data from anywhere they have an internet connection. When businesses switch to the cloud, they are able to eliminate expensive hardware investments and swiftly scale up or down infrastructure as needed. This lets businesses innovate faster without waiting for new technology.
The most common way that companies make use of cloud computing is by hosting their software on cloud service provider’s servers. This type of cloud computing is called Software-as-a-Service (SaaS). SaaS providers host all of the middleware, hardware and application software needed to run an enterprise application in their data centers. They typically provide this service on a pay as you go basis, meaning that the customer only pays for what they use.
Another popular cloud service is called Infrastructure-as-a-Service (IaaS). IaaS allows companies to lease the equipment and storage needed to build its own applications in a cloud computing provider’s data center. This is similar to renting a house that you pay for the rooms you use, like the kitchen during dinner or the bedroom at night.
Finally, a newer cloud service called Function-as-a-Service (FaaS) is emerging that offers even more scalability and agility for business users. FaaS splits cloud applications into small components that are only activated when they’re required in order to pay for the resources you need only when you’re in need of them.
