How To Create launch configuration in AWS By Raj Gupta

We need to Create launch configuration by using below step:-

choose Create launch configuration --->> On the Choose AMI page, select the My AMIs tab, and then select the AMI that you created

On the Choose Instance Type page, select an instance type, and then choose Next: Configure details.

 On the Configure details page, do the following:

• For Name, type a name for your launch configuration (for example, my-launch-config). 
• For IAM role, select the IAM role that you created. This role grants your application the access to AWS it needs
• (Optional) If you need to run a startup script, expand Advanced Details and type the script in User data. 
• Choose Skip to review.

Then click on add storage and then click on next tab security group and add appropriate security group required.

You can select an existing security group or create a new one. This security group must allow HTTP traffic and health checks from the load balancer. If your instances will have public IP addresses, you can optionally allow SSH traffic if you need to connect to the instances. When you are finished, choose Review.

On the Review page, choose Create launch configuration.

When prompted, select an existing key pair, create a new key pair, or proceed without a key pair. Select the acknowledgment check box, and then choose Create launch configuration.
