Public Cloud

Public cloud resources, such as servers, storage, and networking, are shared among multiple users or customers. This shared infrastructure allows the cloud provider to achieve economies of scale and offer cost-effective services.

Users can access and provision cloud services on-demand, often using a self-service portal or API. This means that users can quickly scale up or down their computing resources as needed.

Multiple tenants, or customers, share the same physical infrastructure, but the virtualised resources are logically separated and isolated from each other to ensure data privacy and security.

Public cloud services typically follow a pay-as-you-go pricing model. Users are billed based on their actual usage of resources, which can be on an hourly, monthly, or other usage-based basis.

Public cloud services are accessible from anywhere with an internet connection, making them suitable for remote work, collaboration, and global access.

Cloud providers handle the management of the underlying infrastructure, including hardware maintenance, software updates, and security, freeing users from these operational tasks.

Public clouds are designed to scale resources dynamically. Users can easily add or remove computing capacity to meet changing workload demands.

Major public cloud providers have data centers and availability sones in multiple regions and countries, allowing users to deploy resources in geographically diverse locations for improved performance and redundancy.

Public cloud providers implement robust security measures, including data encryption, access controls, and compliance certifications, to protect customer data and applications.

Public clouds offer a wide range of services, including computing power (virtual machines), storage (object storage, block storage), databases, networking, analytics, machine learning, and more.
