Cloud computing services give you the capability of storing information and workloads in remote repositories accessible via the Internet instead of on the company’s servers and hardware. These services are provided by third-party service providers for a monthly cost, which eliminates the expense of buying and deploying hardware, as well as managing the infrastructure on site.

SaaS (Software as a Service) is the kind of cloud computing that is commonly used in business environments. SaaS applications are simple to use, provide high availability and can be accessed on any device that supports an internet browser or application. They are usually purchased on a per-seat or per user basis, which eliminates the need to buy and install a software package for every employee and provide the hardware to support it.

PaaS (Platform as a Service) is a different cloud computing service that offers application development and deployment through the cloud. It lets developers create applications, test, deploy and manage complete applications in one location. Examples include Microsoft Azure, AWS Elastic Beanstalk and Google App Engine.

IaaS (Infrastructure as a Service) is a different type of cloud computing which offers basic computer infrastructure capabilities like servers, data storage and hardware – all in the cloud. This lets companies host large platforms without the need to invest in large physical infrastructures. Notable IaaS providers include DigitalOcean, Amazon EC2 and RackSpace.

Automated software updates: Cloud-based software automatically refresh and update themselves, reducing the time it takes for IT departments to conduct the manual system updates for all of their organizations. This can free IT staff and IT budgets from excessive outside IT consultation costs, according to PCWorld. Cost uncertainty: Pay-as-you go subscription plans as well as the need to scale resources to meet changing workload demands can make it difficult for companies to estimate their final cloud costs.
