Amazon Route 53 Introduces DNS failover

- moe 14y agoDoes this feature use EBS to store the state?
- mslot 14y agoNo, the health check system does not have a dependency on EBS. More importantly, the health checkers are highly redundant and will continue to function even in case of multiple AZ, region, service, or Internet outages.
- ksec 14y agoRoute 53 is slow ( For a paid solution ). At least when i tested it. It you are doing to use a Third Party DNS that you paid you are either going with the best ones or ones that are good enough like OnApp Anycast DNS.
- saurik 14y agoRecommendations for "best"?
- taligent 14y agoI personally have always liked DNS Made Easy. Affordable, always in the top 3 for speed and lots of features.
- sandfox 14y agoDefine slow? Which particular aspect?
- gtaylor 14y agoWe have found quite the opposite. Route 53 has been very responsive for us all around the world. Also, Route 53 has Anycast support.
- jread 14y agoRoute 53 is becoming a viable alternative to enterprise providers UltraDNS and Dyn. Performance is solid, but features have been lacking. This is a popular feature those providers charge $100+/mo for versus $0.75/mo on Route 53. Monitoring capabilities are limited (tcp and basic http only), but for many this is probably sufficient. DNSSEC is another feature I hope they will support in the future. A few months back I wrote a blog post on the topic of managed DNS provider comparisons (performance, market share, price, features, network size, etc.): http://blog.cloudharmony.com/2012/08/comparison-and-analysis-of-managed-dns.html http://blog.cloudharmony.com/2012/08/comparison-and-analysis...
- nodata 14y agoDo you have any thoughts on Rackspace DNS (http://www.rackspace.com/cloud/dns/ http://www.rackspace.com/cloud/dns/)? It's free.
- boundlessdreamz 14y agoRead that post. So http://www.dnsmadeeasy.com/services/global-traffic-director/ http://www.dnsmadeeasy.com/services/global-traffic-director/ this service is zone based and not geo-ip ?
- jread 14y agoCorrect - it is based on the IP anycast endpoint a resolver connects to, not the geo data associated with the resolver's IP.

- jkat 14y agoWould be nice to have the ability to set up some type of alert/notification.
- kamakazizuru 14y agonoob question - why use load balancing if DNS failover does essentially the same thing?
- jread 14y agoDNS failover is subject to DNS caching and TTL. Load balancing is real time. A DNS driven failover may take 1-10 minutes to trigger versus instantaneous for load balancing. Good approach to failover is a combination of both.
- lazyant 14y agoisn't this offering cannibalizing AWS load balancers? if I have a set of web servers with a load balancer at front and health checks that takes unhealthy nodes out of rotation, isn't it cheaper now to just use this DNS fail-over? http://aws.amazon.com/pricing/elasticloadbalancing/ http://aws.amazon.com/pricing/elasticloadbalancing/ http://aws.amazon.com/route53/pricing/ http://aws.amazon.com/route53/pricing/
- jread 14y agoNot really - DNS failover is typically much slower to respond compared to load balancing because records are cached.
- dsl 14y agoELB is a local load balancer, distributing requests to local servers based on load and availability. R53 is a global traffic manager, distributing requests to datacenters to provide failover and latency optimization.
- forcer 14y agoWe use DNS Made Easy but and are happy with them. However, for our level of DNS queries per month - e.g. over 50million Route 53 would give us some significant cost savings. Do you guys know whether Route 53 offers templating mechanism? e.g. setup 1 template and apply to 50 different domains?
- donavanm 14y agoNo template DSL/system in the console. But there is an API with quite a few client libraries. Shouldn't be much work to whip one out. Or it may exist already, actually.
- jeffbarr 14y agoThe AWS templating mechanism is called CloudFormation. Here's a snippet of a Route 53 template: ( http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/quickref-route53.html http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuid... ).
