I would like to solicit constructive feedback in regards to a distributed DNS zone hosting proof of concept I'd like to design and establish.
I must deploy a DNS system with the following requirements: - single master server, multiple slave servers - minimal time for name resolving for Americas, Europe and Asia - up to millions records in a domain zone - changes propagate in real time (master -> slaves), 2 sec max delay - automatic slave data re-syncing on master link restore after disconnect - API for zone records manipulation (insert, update, delete) So far I am considering using (free) DC/OS on Amazon Web Services with the latest version of BIND containerized using docker on a Linux or Unix OS. Dyn and Infoblox are also on my list of items to research but I have never used either and I enjoy working with BIND on Linux. After all this is the BIND Users group, but I would be interested to know if someone can make a case for using Dyn or Infoblox in this case. Considerations/questions I have about this deployment for this Bind-Users forum are: 1. How can I examine DNS resolution times using this platform (or other platforms to compare with) in different geographic areas of the world without first deploying it? I will need to have benchmark data to test against to verify I am getting the fastest speeds possible on name resolutions. 2. How to handle millions of records in a DNS zone, and how common is it to have millions of records in a DNS zone? 3. What API solutions for DNS zone edits currently exist or should I be lookin into? I will research more in the next day but so far I know I can manually configure named.conf to propagate zone changes to slave servers rapidly (aiming for 2 seconds or less) using NOTIFY messages and zone transfers, and also configure slave servers to automatically re-synch zone data with the master server upon reestablishing a connection. That should satisfy two of my requirements above. Any additional advice, hints, or tips for my proof of concept would be greatly appreciated! Thanks in advance. This will be a very fun project to design and hopefully implement. -- Sent from: http://bind-users-forum.2342410.n4.nabble.com/ _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
