Public cloud is considered to be the most standard, widely recognized, and largely used of the available cloud computing models. As the name suggests, this cloud model is available on the public network like Internet making it easily accessible to all categories of clients. It is a fully virtualized platform based on the shared-resource architecture making it resilient when compared to other cloud computing models.

Standout features include:

1. Pay only for what has been utilized in terms of usage for the CPU cycles, storage, or bandwidth.
2. Faster deployment as it requires zero infrastructure installation.
3. Access anywhere by anyone through any device for its availability on public network.
4. Infinite scalability with resources used as per demand and with applications or storage usage fluctuating up and down.

Despite security being a concern as this cloud is available publicly, appropriate implementation to effectively manage security with methods that are widely available outweighs the problem and this has managed to keep public cloud the most desired one by the clients across platforms.
