Yes, I know I write a lot about AWS these days, but you know, obsession is my thing. So as I wrote earlier, I generate my CloudFormation templates using troposphere, and the one thing I had to finish today was to register a latency based Alias record on Route53 for an ELB. While Route53 GUI is fairly easy to use, I’ve been stuck on its programmatic emanation for quite a while, so here’s a troposphere definition of such a CloudFormation object:
So you’re using AWS CloudFormation in order to bring up complex infrastructures; haven’t you already told yourself that instead of writing down all those JSON lines by hand, you could bring more fun to your architect life? I did, and I found a way to programmatically design a whole architecture using troposphere and boto3. Simply put, troposphere gives you bindings in order to generate CloudFormation’s JSON template, but hey, it’s python, meaning that you can create loops, use conditions and even dynamically build objects.
