High-Performance DNS for The Cloud - igvita.com

DNS is a great example of a service that couldn't possibly work on paper, but performs spectacularly in practice, even with a hodge-podge of implementations all over the Internet.
DNS is a great example of a service that couldn't possibly work on paper, but performs spectacularly in practice, even with a hodge-podge of implementations all over the Internet. First, the authoritative DNS servers responds with a Time To Live (TTL) timestamp for every record (which you should keep fairly low in a virtual deployment environment), then the upstream DNS servers cache that same data, albeit usually with different policies (determined by the ISP). And finally, your router, OS, and the browser all have their own and independent DNS caches. (Firefox 2/3 caches all DNS records for a 1 minute, IE 5/6/7 for 15 minutes). Talk about a mess!
Good tips on using DNS in the cloud, and in particular using a staging environment that is switched over (via DNS) to a production environment.
