AWS CloudFormation now allows you to protect a stack from being accidently deleted. You can enable termination protection on a stack when you create it. If you attempt to delete a stack with termination protection enabled, the deletion fails and the stack, including its status, will remain unchanged. To delete a stack you need to first disable termination protection.
Stack Termination Protection is available in the following regions: US East (Ohio), US EAST (N. Virginia), US West (N. California), US West (Oregon), Canada (Central), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), EU (Frankfurt), EU (Ireland), EU (London), and South America (São Paulo).
