In what context you said that when you create golden ami you can delete nat gateway also 1.40.46

Sir there is no doubt in it. It was a fantastic demo 🥳🎉 Thanks for putting so much your efforts and time 😍 And one more doubt here whenever it comes to ASG we create images from existing app or web instance right na What if we have to update some changes to our application and the new changes which we made to our application that is automatically reflected to all ASG instances or Again we have to create new image? Or else again we have to make auto scale to 0 and then re scale it back to ? How exactly it works. Can you please clarify my silly question sir.

[@avizway]

We follow strategies i.e; blue and green deployment methods for zero downtime migrations from one version to another version. 1. Create a goldenami with updated application 2. Update the existing Launch Template with new golden ami 3. Configure ASG to use new Launch template 4. Delete 1 instance, new instance comes with latest data, once its fully functional, then delete other instances.

Superb Avinash Garu, awesome content... 👌👌 I have One Question. If we need to change the code in Web and Application, how do we update that code in EC2?

[@avizway]

We have 2 options, 1. We can create a new GoldenAMI and update the Launch Template and ASG. 2. We can use CICD tools and update the code with pipelines.

Facing the same issue did u solve it?

[@ceemarlaraju3971]

Because of igw and route table. First deassociate the public subnets from public route table.again associate those public subnets
