A public cloud, such as Microsoft Azure, is an example. In a public cloud, you share the same infrastructure, storage, and network devices as other businesses or "tenants," and you use a web browser to access services and manage your account.
AWS, Microsoft, and Google are the three biggest public cloud providers today. These companies employ a basic pay-per-use model to supply their services over the internet or through dedicated connections. Each vendor offers a variety of solutions tailored to specific workloads and business requirements.
Google's back-end data for applications such as Google Drive, Google Docs, and YouTube, among others, is not accessible to the general public; these types of data and applications are hosted on a private cloud.
Google plans to move a portion of YouTube's infrastructure to its Google Cloud platform. While Google has its own public cloud platform, many of the company's core services, such as its search engine and YouTube, are still hosted on internal infrastructure that is not connected to GCP.
Azure machines are organised into cloud services and answer to the same domain name with different ports, whereas AWS machines can be reached individually. AWS has a Virtual Private Cloud, whereas Azure has a virtual network cloud. There are 140 availability zones in Azure, compared to 61 in AWS.
