Amazon Web Services (AWS) provides a wide array of cloud computing solutions. Mastering the AWS Command Line Interface (CLI) is an essential skill for developers, system administrators, and cloud engineers working within its ecosystem.

Every organization has to assign privileges to its user accounts. Good security practice requires each account to have only the privileges necessary for the role it’s assigned to.

It is used by developers in their tech stacks and even by large enterprises and corporations to store website and application data. PostgreSQL uses SQL query language to store and manipulate data and also provides JSON support.
