ServiceNow is a cloud-based platform which allows companies to automate many of the business processes in the cloud. It includes areas like IT (ITSM and ITOM), HR, Finance, Security, Customer Management, Facilities and your custom applications.
Among the key strengths of ServiceNow is how quick and easy it is to extend its functionality. It primarily can be done through straightforward configurations, workflows and Javascript, which can be applied either for client-side functionality (at the browser level) or backend functionality (business logic in the server-side).
