- Create a ec2 machine manually
- To create ec2 machine we need
- AMI => ubuntu
- instance type => t2.micro
- Network, subnet & public ip => subnet => subnet1 with public ip
- Security group => create a security group
- key pair => Use an existing key pair with choice to user
- Lets create a security group resource

Updating the template is also possible. Whenever you change any field look at update requires. If the value of it is replacement, it means downtime ( a new resource will be created as a result of this)
-
We still have a problem, our ec2 machine is not getting public ip address and this template works only in oregon (as AMI is hardcoded)
