Application Hosting is most commonly offered as Software as a Service (SaaS) subscription which allows businesses to run their applications on servers or in a cloud that is hosted by a service provider such as AWS (Amazon Web Services) and GCP (Google Cloud Platform). Businesses do not have to invest in building and maintaining the underlying infrastructure which enables them to lower their costs by paying only for what they use, enjoy seamless upgrades in functionality, and easily integrate with their existing data and systems.
