Today I learned about AWS EC2 and their security groups. How we can create a webserver using EX2.
First time when I launched, I was not aware of the security group. I tried to start the apache2 service but still when I am going to the IP. I was unreachable. After that I came to know about the security group in AWS.
security groups are used to manage the port that are accessible to outer world. Anyone with the request of the webpage came to firewall first. Firewall uses security groups. Security group consists of three main things. Port Range, Protocol and Source. In source we can select whether we want it to be accessed from the Anywhere, use your IP or you can specify the IP as well.
It helped to start my first webserver using AWS EC2.
