![]() your blog) or if that domain is managed by a different provider than Route 53.ĭepending on who manages your domain (e.g. We will also look at how you can set up your Hosted Zone if you are already using your Route 53 domain for another purpose (e.g. The Hosted Zone is easiest to set up if you have a domain that is managed by Route 53 and that you don’t use for anything else yet. To register DNS records in AWS, we need to create a Hosted Zone in Route 53. ![]() In the next chapter we will take a look at each part in detail. The website can then take the URL, extract the subdomain and ask for the right picture. At the core of the solution are wildcard ARecords which let us route traffic for any subdomain to a particular target. You can see above that only the domain changes, but nothing else. Multiple frontend deployments increase complexity. As a developer I want the least amount of complexity possible. As a customer I want to go to or or any other address in the format *. and then see a picture for the word in the beginning. Let’s find a solution by putting us in the customers shoes. Optional: Understanding how DNS and especially nameservers work will help you a lot with troubleshooting potential routing issues. We will need this for the DnsValidatedCertificate. Please bootstrap your account for CDK by running cdk bootstrap. Let me know if anything breaks in newer versions! It’s also good to have an unused domain registered in Amazon Route 53, but we will learn how to use other providers and used domains as well. To deploy the solution of this article, you should have an AWS account and some experience with the AWS CDK. Check out the full source code on GitHub. The magic is in the chapter “Wildcard Routing”. Shortcut: If you don’t need Infrastructure as Code (IaC), then an ARecord in Route 53 with *. that points to your existing CloudFront distribution gets you the same result. ![]() That will enable you to give each of your customers a customized experience, while having just one frontend deployment. This article explains how you can point multiple subdomains to the same frontend deployment by creating DNS records and a static website with the AWS Cloud Development Kit (CDK). Recently I learned that you can use DNS ARecords to route all requests under a certain domain to the same frontend. Eventually there were six different frontend deployments, multiple branches and the code bases started to diverge. To give each of the clubs a customized experience, we provided each of them with their own subdomain. When it came to customization, things got tricky: Each club had a different name, different pictures, and sometimes even different questions they wanted to ask their customers. In its core, the shop was a webapp that processes payments and sends PDF via email.
