On-premise computing involves hosting and managing software and hardware within an organization's physical premises, providing direct control over data, security, and maintenance. It often requires significant upfront investment in infrastructure and ongoing costs for maintenance and upgrades. In contrast, cloud computing delivers computing services—such as servers, storage, databases, networking, software, and analytics—over the internet ("the cloud"), typically on a pay-as-you-go basis. This model offers scalability, flexibility, and reduced capital expenditure, allowing organizations to quickly adapt to changing needs without the burden of managing physical hardware. However, it may raise concerns over data security and compliance, as data is stored off-site and managed by third-party providers.
