Cloud computing solutions allow companies to store their information in remote repositories through the Internet instead of on their own hardware and servers. These capabilities are offered by third-party service providers for a monthly cost, which eliminates the expense of purchasing and deploying hardware and managing infrastructure on-site.

SaaS (Software as a Service) is the kind of cloud computing that is most commonly used in the business environment. SaaS applications are easy to use, provide high availability and can be used via any device that can run the web browser or app. They are usually purchased on a per-seat or per user basis, eliminating the need to purchase and install a software program for each employee, and also provide the hardware required to run it.

PaaS (Platform as a Service) is another cloud computing service that provides application development and deployment on the cloud. It allows developers to build, test, deploy and manage whole apps in one location. Microsoft Azure, AWS Elastic Beanstalk, and Google App Engine are all noteworthy examples.

IaaS is a cloud computing platform that provides basic infrastructure capabilities including servers, storage for data, and hardware. This allows companies to host large platforms without having to invest in massive physical infrastructures. IaaS providers include DigitalOcean and RackSpace.

Cloud-based software automatically refresh and update themselves, reducing the time required for IT departments in order to carry out the manual system updates for all of their organizations. This can free IT staff and IT budgets from unnecessary outside IT consultation costs according to PCWorld. Cost uncertainty: Pay-as-you go subscription plans and the need to scale resources to meet demand for workloads that fluctuate can make it difficult for businesses to anticipate their final cloud costs.
