Public Clouds

Public clouds are a type of cloud computing that provides shared computing resources, from servers and networking to storage and databases, over the Internet. Unlike private clouds, which are dedicated to a single organization, public clouds are hosted by third-party providers and accessible to anyone with an internet connection. This makes them an attractive option for businesses of all sizes, as they offer scalability, flexibility, and cost-effectiveness.

Benefits of Public Clouds

There are many benefits to using public clouds, including:
