There are advantages from a business perspective as well as from the user’s viewpoint.
User benefits: Data storage media are obsolete and can longer be lost or damaged. Hardware does not need to be upgraded regularly. You can use services from multiple devices. You only need internet access.
Business benefits: Cloud services can be easily leased at a predictable cost. High acquisition costs fall away. Personnel requirements are also reduced: Maintenance of hardware, updates, inventory management, prevention of downtime: The cloud takes care of all these factors.
An additional cost advantage is the scalability of the cloud. In principle, organisations with volatile service requirements need to gear their entire IT to peak loads – this results in regular over-supply of capacity. Computing power, the number of workstations, server capacity etc. can be flexibly scaled in the cloud.
