A public cloud is a cloud infrastructure that is open for use by different clients. Connecting to the public cloud allows any user to remotely access computing resources, databases, file catalogs, and other information. The cloud infrastructure is managed and owned by a cloud provider.
The main benefit of using the public cloud for any user is that there is no need to purchase, configure and maintain your own infrastructure. Modern cloud platforms allow you to scale computing resources and storage capacity almost without limits. You can access the public cloud from anywhere in the world, provided you have an Internet connection.
The world’s most popular cloud services are:
- Google Drive, Dropbox and Amazon S3 offer you the ability to store and synchronize files on public servers.
- Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform allow you to rent virtual servers, storage, and other resources to deploy applications and development environments.
- Google Workspace, Microsoft 365 and Salesforce organize access to business applications without the need to purchase and install software.
