Thats very cool

Do you have to pay for your traffic twice?

... and does this add hops?

sspies6• 11 years ago

Id adds one hop (our appliance) to the path. It tries to increase performance of your path by taking non-standard BGP metrics into account: congestion and latency

sspies6• 11 years ago

Nope

If your application goes down, all you want is to get it back up. What if your cloud provider is down? Use DATAPATH.IO to route your users to a healthy location while keeping your IP addresses.

But... what happens if datapath.io goes down?

mmastrac• 11 years ago

I think the idea is that datapath only functions when you go down. ie: if only you go down, datapath will fix it via BGP magic. If datapath is down and you are up, stuff continues to work.

Their twitter feed has a diagram describing the process on AWS: https://twitter.com/datapath_io/status/560027255188250625/ph...

This is a clever architecture; I never thought about using VPC direct connect to get out to the Internet.

chrisfarms• 11 years ago

I assume this is BGP routing as a service (which sounds cool).

But, would this not break the internet if everyone used it? routing individual IPs (rather than large blocks) sounds like it would end in chaos?

In general, most ISPs will drop any routes more specific than a /24. Presumably datapath has negotiated with some specific providers to allow /32s; it's up to that ISP to scale their routers to handle it; other ISPs will only see the /24 aggregate.

Call me crazy, but I'm not sure I really care about keeping my IPs. Route 53 seems as close to bulletproof as we're going to find with DNS, and it's got cloud-independent failover routing built in. Point the primary record at your nice little EC2 server, and have the secondary record pointing as Azure or Google Cloud or your mom's laptop, whatever, and it'll do what Datapath is doing without futzing with your routing. ...right?

You cannot do graceful failovers with Route 53. This is, because DNS is a system of many dependend caching layers and the TTL value is not realiable.

the TTL value is not realiable.

How is the TTL not reliable?

In my personal experience DNS cut-overs have never been a problem. Is there any major OS or ISP doing DNS wrong?

I'd suggest you scrap your "fancy" website and replace it with two paragraphs of text that explain what you are trying to sell and how it works.

The "vague bullshit in between cute animations" approach really doesn't work at all for this type of product.

When I first saw the page (opened along with a bunch of other tabs from HN links), with its "Timeout error!" balloon and "Service disruption" headline, I thought it was a fancy error page and hit reload. Oops.

Doesn't every CDN already accomplish the same functionality with multiple origins and failover detection, while accelerating static content by caching it at the edge? Given how cost competitive CDNs already are, I don't see how they can charge a low enough cost in comparison to be compelling, while still incurring bandwidth costs and at least some network infrastructure which make it almost as expensive to run, minus some caching nodes. And if for whatever reason, there does happen to be some use case for anycasting the IP that's advantageous, any CDN could add this feature overnight while having a much more established footprint and infrastructure in place.
