AWS EC2 instance

• Lets create an ec2 instance with ubuntu 22.04
• While creating the ec2 ensure the security group has 80 port opened and you select any key pair
• Login into ec2 instance and then install nginx

sudo apt update 
sudo apt install nginx -y

• Navigate http://<public-ip> from browser
  
• Doing the same steps by using user data.
• User data in AWS can run a script once when you are creating a new ec2 instance
  
  
  
• when userdata is not working refer to /var/log/cloud-init*.log
• Rebooting the AWS instances will not change the public ip, stop and start will change the public ip.
