Cloud computing allows businesses to function more efficiently by improving their capacity and capabilities, without requiring them to invest in physical infrastructure. Anywhere there’s an internet connection, there’s potential to access cloud resources. This eliminates the need for hefty upfront investments and allows businesses to scale resources based on demand.
