What Is a Free Cloud Server?
A free cloud server is a remote virtual machine offered at no cost by cloud service providers. These servers allow users to deploy applications, host websites, or run development environments without paying for infrastructure. While they come with limitations (such as reduced CPU power, storage, or bandwidth), they are perfect for small projects and learning purposes.
Key Features of Free Cloud Servers:
- No Cost: Ideal for budget-conscious users.
