Public clouds are shared infrastructures from "summary" of Cloud Computing For Dummies by Judith S. Hurwitz,Daniel Kirsch
Public clouds are shared infrastructures, which means that multiple organizations use the same physical hardware and software resources. These resources are dynamically allocated and reassigned based on demand. In a public cloud environment, users access computing resources over the internet. One key benefit of public clouds being shared infrastructures is cost savings. By sharing resources with other organizations, users can access computing power and storage capacity at a fraction of the cost of building and maintaining their own infrastructure. This cost-effective model allows organizations to scale their IT resources up or down based on their needs, without having to make significant upfront investments. Another advantage of public clouds being shared infrastructures is flexibility. Users have the ability to quickly provision and de-provision resources as needed, allowing them to respond to changing business requirements in real time. This flexibility enables organizations to innovate faster and stay ahead of the competition in today's fast-paced business environment. Despite the benefits of public clouds being shared infrastructures, there are some potential drawbacks to consider. One concern is the issue of security and data privacy. Because multiple organizations are using the same resources, there is a risk that sensitive data could be compromised if proper security measures are not in place. It is essential for organizations to carefully evaluate the security capabilities of their cloud provider to ensure that their data is protected.- Public clouds being shared infrastructures offer cost savings, flexibility, and scalability to organizations. However, it is crucial for users to address security concerns and work closely with their cloud provider to implement robust security measures. By understanding the implications of sharing resources in a public cloud environment, organizations can leverage the benefits of cloud computing while mitigating potential risks.
