Looking for: Web Service Architects

Im looking for someone that can give some quick advice and guidance regarding the architecture of a low latency / high volume / high concurrency web service.

Give me a shout if you have this experience, or know of someone.

Cheers
Tijn

Hi Tijn, PM Sent.

I had the same requirement and built my own webserver and used Amazon AWS for hosting and auto-scaling depending on load.
I wrote everything in Java, the only slow thing about Java is the initial once-off startup time.

Round trip requests take a mere 60ms now and each server instance can handle max 2800 requests/second. Amazon charge me about $90/month for 1 load-balancer and 1 running instance, not bad.

Sounds awesome seank. Are you supporting php in that setup?

60ms from what distance though? Even DNS querys take upwards of 60 msec just across the eastern US. AWS has a big problem with io performance, you will bottleneck IO quickly before CPU with their *scaling*. Haha I don't think they sell IOP :-)

Hi tijn, no php, it's all Java as that's my forte.

Hi Tyler, true when I ping the amazon server in US-east-1d from Belgium I get a reply in 113ms, but you're right the load test was done from within the US. I need to look up that site's name, it was mentioned here on STM a while back. When I find it I can see how many concurrent requests were run on that test.
