Amazon EC2 : Protect instances from unintentional shutdown

You can now enable accidental stop protection for EC2 Instance just like accidental termination protection

here is how you can do in 6 easy steps

1. Select your EC2 Instance
2. Click on Actions
3. Click Instance Settings
4. Click Change stop protection ( this is the new feature added)
5. Select Enable under Stop protection
6. Click Save

To disable the feature just uncheck the "Enable" option at Step 5

Special Considerations:

• Not applicable for Scheduled Event that stops the instance
• No change to Auto scaling behavior ( if instance is unhealthy instance will be terminated per ASG rules)
• Not applicable for instance store-backed instances
• Not applicable for Spot Instances.
