Public Cloud
A computing model where services and resources are provided over the internet by third-party providers and shared among multiple users.
Description
The Public Cloud refers to a cloud computing environment where resources such as servers, storage, and applications are delivered over the internet by third-party providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform. These services are available to anyone who wants to use them, making it a cost-effective solution for businesses of all sizes. Users can access shared resources on a pay-as-you-go basis, which helps to minimize capital expenditures. Public Cloud environments are highly scalable, allowing businesses to quickly adjust their resources according to demand. They are particularly beneficial for applications that experience variable workloads, as users can scale up or down without needing to invest in physical infrastructure. Security measures are implemented by the provider, but businesses must also consider their own security protocols when using shared environments. Overall, the Public Cloud provides flexibility, speed, and cost efficiency, attracting a wide range of users from startups to large enterprises.
Examples
- Amazon Web Services (AWS) Elastic Compute Cloud (EC2) offers scalable compute capacity in the cloud.
- Google Cloud Storage provides a unified object storage solution for developers and enterprises.
Additional Information
- Public Clouds typically operate on a multi-tenant model, meaning resources are shared among multiple users.
- They are ideal for applications with unpredictable workloads and for businesses looking to avoid the costs associated with physical hardware.
