We’ll go into the realm of public cloud computing in this post, looking at its definition, advantages, use cases, and potential downsides.
Introduction to Public Cloud Computing
Public cloud computing refers to a cloud computing model in which cloud services are offered and managed by third-party providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). These providers host a variety of resources, including servers, storage, databases, networking, and software applications, which are made available to users over the internet.
How Does Public Cloud Computing Work?
Public cloud computing works by providing on-demand, scalable, and elastic computing resources to users over the internet. The resources are owned and managed by a third-party cloud service provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform.
Users must first register for an account with a cloud service provider in order to use public cloud computing. They can provision the resources they require, like virtual machines, storage, and bandwidth, once they have an account. After that, users only pay for the resources they really use, thanks to a pay-as-you-go billing system for the resources.
