What is cloud computing?

Cloud computing is defined as the delivery of computing services over the internet. This encompasses a variety of resources such as servers, storage, databases, networking, software, and analytics, all of which can be accessed and managed remotely. The key aspect of cloud computing is its reliance on remote servers and infrastructure rather than local resources, allowing for greater flexibility, scalability, and accessibility. Users can benefit from these services on a pay-as-you-go basis, meaning they can adjust their usage based on current needs without the need for significant upfront investment in physical hardware.

In contrast, the other options focus on local or traditional computing methods. Storing data locally refers to keeping information on individual computers rather than using cloud storage, which is inherently not a characteristic of cloud computing. Increasing hardware performance is about enhancing the capabilities of existing systems and does not directly pertain to the internet-based model of service delivery that defines cloud computing. Similarly, managing local servers does not align with the core concept of cloud computing, which relies on accessing and utilizing services provided remotely rather than through local infrastructure. These differences highlight the unique nature and advantages of cloud computing.
