Apache Web Server maintained by the Apache Software Foundation is a popular open-source web server creation, deployment, and management tool. Its features include an authentication mechanism, database support, server-side scripting, and support for multiple programming languages. Apache’s ability to handle large amounts of traffic with minimal configuration is one of its advantages. Apache runs on Linux, macOS, and Windows. Web hosting companies use it to provide shared/virtual hosting. Apache Web Server, by default, supports and can differentiate between multiple hosts that reside on the same machine.
