   10.Go to Instance ID > Security > Select Security Group >Inbound Rules > Edit Inbound Rules >Delete existing rule

   11.Add New rule >All Traffic > Anywhere-IPV4 > Save Rules:

12.Connecting to the instance

1. Select the instance > Connect to instance > SSH Client > Copy Example link

2.Go to system & launch CMD (Run as a admin)

3. $ cd \

4.$ cd \users\admin\downloads

5.Paste the example link (right click) > enter > sudo yum update -y

   9. Launch Instance.

   10. Go to Instance ID > Security > Select Seciruty Group >Inbound Rules > Edit

Inbound Rules >Delete existing rule

11. Add New rule >All Traffic > Anywhere-IPV4 > Save Rules

12. Connecting to the instance

    1. Select the instance > Connect to instance >EC2 instance Connect > Connect
