What is SSL?

SSL Stands for Secure Socket Layer which enables encryption -based internet connection protocol for providing privacy, secure authentication, integrity to internet connection. SSL eventually know to be the TLS which stands for Transportation layer security.

A website that implements SSL/TLS has "HTTPS" in its URL instead of "HTTP."

Lab Work :-

1. Create a Resource Group .

2.  Create a virtual-network into the resource group.

>> Create a web-subnet inside the azure-virtual-network which will contain the web-server.

3. Deploy the web-server into the web-subnet in azure-virtual-network.

4. Setup or Install Apache2 into your server.

>> Command to install Apache2 is "apt install apache2".

5. After Configuring Apache2 into the server you need to copy all the required files to /var/www/html directory.

>> command to start the Apache2 into your server is :- "systemctl start apache2" and  "systemctl enable apache2".

6. Allow HTTP and HTTPS port to the web-server in Networking tab.

>> Port _80 is for the HTTP and Port_443 is for HTTPS.

>> Then your website will be operational, and you can view it by making a Google request to the server's IP address.
