The dirty secret of ec2: it cannot currently be made HA (highly available)
- wmf 18y agoThis is true, but most people don't care. Worse is better.
- elsewhen 18y agoi think amazon knows that high-availability is important to some clients, and i wouldnt be surprised if they release a load-balancing service.
- bbgm 18y agoGiven recent moves towards enterprise offerings, that's almost certainly going to happen (or they'll just partner with Sun or Platform)
- handelaar 18y agoSurely this can be mitigated in software outside Amazon's services? Very low TTL/expiry values in DNS and name servers outside the cloud would get you the right result via a different route. At the cost of having to pay close attention to your DNS service, of course.
- elsewhen 18y agoi dont think dns can solve the problem. dns info is cached in all sorts of places including at isps all over the internet. if your server (or cluster of servers) in ec2 goes down, and your dns server redirects to a different IP, the old IP will still be cached. this is far from a highly availalble system.
