Terraform contd..

• Creating a Security Group in AWS, which is used as firewall for the virtual machines.
  • We need to open 22 port for ssh communication from anywhere (0.0.0.0/0)
  • We need to open 80 port as we will be using this for web servers
  • you can give the name of the security group as webserver
    
    
• Write the terraform resource to create the same security group in the vpc created by terraform
• Refer Here for the official docs
• Refer Here for the changes done
  
• Now lets assume in our application architecture we use
  • web servers => apache which runs on linux machine and can be accessed over port 80
  • application servers => tomcat which runs on some linux machine and can be accessed over port 8080
  • databases servers => mysql which runs on port 3306
• We need to create two more security groups
• AWS Architecture for ntier application
  
• AZure Architecture for ntier application
