A few weeks ago I used AWS S3 for 301 redirects, with Cloudflare on top to cache these requests, few as they were. This effectively maintains a handful of links which redirect somewhere useful, while directing all other traffic to this domain.
The results are great! The switch to S3 was made on the 9th, and a Cloudflare page rule added on the 10th – at which point over 60% of requests became cached.
If you’re using a CNAME on your root domain, you’re gonna have problems. That’s just a DNS thing – and if you want to host a root domain on S3, you won’t be provided with an IP address by AWS. You can solve this if you use Route53, but what about if you want to keep your domain in Cloudflare?
You’ll also have problems if you want to use Cloudflare Full SSL on an S3 bucket configured for static website hosting – resulting in nothing but Cloudflare error 522 (Connection timed out) pages.
This post details my switch over to using Powershell and Cloudflare to update a DNS record to a server’s current IP. This effectively emulates dyndns for this host – except it’s free.
There are a load of other options out there, which even include some simple-but-quite-clunky apps for domain registrars like NameCheap; but installing third party software is not the route I want to take.
I previously had my target domain (let’s call it targetdomain.com) hosted on a Linux box, and used SSH to update the DNS settings via a Windows server. This worked well for three years without a blip – but was clunky. I was using a scheduled task to start a bat file, which then ran Putty to run the shell script…to update a config on a server which was only hosting the domain to serve this purpose.
I’ve been using Cloudflare for years, and set aside time to write a script to use their service for this purpose. As it turns out, people have done this for years – so I’ve taken one off the shelf.
