Hello, I also had a question regarding stacks in CloudFormation. How would I go about checking the individual cost of a stack created? I know when creating the template you can use the AWS Pricing Calculator to determine that information prior to creation, but wanted to know how to check that information after the fact. Any thoughts?

Thanks for posting a very beneficial video. I am editing the template file to create more resources( security group) but they are not getting created. It fails with a msg rollback complete. Why is a new template required each time?

Hi Stephane.
Just a quick question. As you said when I update the cloud formation stack, it deletes the old instance and creates a new instance. But I have the old instance with important services installed. The new instance doesn't have it installed.
Any thoughts on why it is doing that?
I saw there is another way, which is importing resources into the current stack, but we need to give a deletion policy for the modified resources.
Any other suggestions to update just the stack template without affecting/modifying the instance?

[morgandeano]

Why didn't it simply modify the existing instance with new EIP and SGs?

[hoovie]

Can you programmatically upload files to the newly created instance using CloudFormation?
