What is Public Cloud?
A Public Cloud refers to the cloud computing service model where computing services are offered by a third-party service provider to the public through the internet. Public cloud essentially saves an organisation from spending on setting up and maintaining its own on-premise cloud computing infrastructure. A public cloud environment can be implemented much faster as compared to a private cloud environment. It provides customers access to large pools of networking, storage and computing resources, ensuring higher scalability and accessibility. Public cloud service providers commonly have several data centres across the globe, allowing customers to access their services at any time, anywhere as long as they have internet connectivity.
Points to Remember
- Public cloud services are offered by providers either for free or on a fee-based model.
- Public cloud services are often deemed less secure than private clouds. However, public clouds can be effectively secured using adequate tools and technologies such as intrusion detection and prevention systems (IDPS).
