  Introduction JavaScript is a programming language used primarily by Web browsers to create a dynamic and interactive experience for the user. Most of the functions and applications that make the Internet indispensable to modern life are coded in some form of JavaScript. The earliest incarnations of JavaScript were developed in the late 1990s for the Netscape Navigator Web browser. At the time, Web pages were static, offering little user interaction beyond clicking links and loading new pages. For the first time, JavaScript enabled animation, adaptive content and form validation on the page. JavaScript did not become standardized and widely adopted until 1999. Even after standardization, browser compatibility remained an issue for over a decade. JavaScript is used in almost every domain Web Applications Web Development Mobile Applications Server Applications Web Servers What is JavaScript used for? JavaScript is mainly used for web-based applications and web browsers. ...

What is python CGI? Python is one of the most popular languages nowadays and Docker is used for containerization.  A CGI script is invoked by an HTTP server, usually to process user input submitted through an HTML <form>  or <isindex>  element. Most often, CGI scripts live in the server’s   special cgi-bin  directory. The HTTP server places all sorts of information about the request (such as the client’s hostname, the requested URL, the query string, and lots of other goodies) in the script’s shell environment, executes the script, and sends the script’s output back to the client.

Containers are isolated from one another and bundle their own software, libraries, and configuration files; they ...

 Task 18 Description -  Create an AWS EC2 instance  Configure the instance with Apache Webserver.  Download PHP application name "WordPress". WordPress stores data at the backend in MySQL Database Server. Therefore, you need to set up a MySQL server using AWS RDS service using Free Tier. Provide the endpoint/connection string to the WordPress application to make it work. WordPress WordPress is a free and open-source content management system written in PHP and paired with a MySQL or MariaDB database. Features include a plugin architecture and a template system, referred to within WordPress as Themes.

TASK 12 DESCRIPTION - Use Ansible playbook to Configure Reverse  Proxy i.e. Haproxy and update its configuration  file automatically each time a new Managed node  join the inventory.  Proxy i.e. Haproxy and update its configuration  file automatically each time a new Managed node  join the inventory Configure the same setup as 12.1 over AWS  using instance over there . REVERSE PROXY In computer networks such as the internet, a reverse proxy is a common type of proxy server that is accessible from the public network. Large websites and content delivery networks use reverse proxies –and other techniques– to balance the load between internal servers. The reverse proxy becomes a single point of entry for the different web applications in the organization. The web servers stay hidden and thus protected from the Internet. Security monitoring such as log review can be performed from a single point. Configuring Haproxy via Ansible Playbook First, we have to ge...
