LAMP Stack Ubuntu is used for Linux, Apache, MySQL, and PHP. This combination is suitable for WordPress, PHP applications, and REST APIs.
WordPress and PHP applications have been deployed using LAMP Stack Ubuntu on a recent project.
In one of those deployments using LAMP Stack Ubuntu, a developer receives a request on the web page. Apache receives that request, PHP processes the logic, and MySQL provides the data as a database. Then the response is sent back. It is used for WordPress hosting, PHP applications, internal tools, and for running the back end.
For those who want to use the classic web stack for Linux, Apache, MySQL, and PHP all-in-one for dynamic hosting websites, WordPress, small PHP applications, and REST APIs, LAMP Stack Ubuntu is a viable option.
