A public cloud infrastructure refers to a cloud computing environment that is made available to multiple organizations or individuals over the internet. In a public cloud, resources such as computing power, storage, and networking are shared among users who access and pay for these resources on a pay-as-you-go basis.

  1. Shared Resources: Public clouds are shared among multiple users, with resources dynamically allocated based on demand. This multi-tenant model allows for cost efficiency and resource optimization.
  2. Scalability: Public cloud providers offer virtually limitless scalability, allowing users to quickly scale up or down their resources based on changing requirements. This scalability is achieved through the use of automation and virtualization technologies.
  3. On-Demand Access: Users can access public cloud resources on-demand through self-service portals or APIs, enabling rapid provisioning of computing resources without the need for manual intervention.
  4. Pay-Per-Use Pricing: Public cloud services typically follow a pay-per-use pricing model, where users only pay for the resources they consume. This can result in cost savings for organizations, as they only pay for what they use without the need to invest in and maintain their own infrastructure.
  5. Global Reach: Public cloud providers operate data centers in multiple regions around the world, allowing users to deploy applications and services closer to their end-users for improved performance and reliability.
  6. Managed Services: Public cloud providers offer a wide range of managed services, such as databases, machine learning, and analytics, which users can leverage to build and deploy applications more efficiently.
  7. Security and Compliance: Public cloud providers invest heavily in security measures to protect data and infrastructure from cyber threats. They also offer compliance certifications and tools to help users meet regulatory requirements.
