There's cookie-based caching in Varnish (and in some other proxy caches too). Essentially, the key is going to be made of the usual hash + the cookie like this: sub vcl_hash { set req.hash += req.http.cookie; } What this means is that t

It really depends on what app you're running. Let's look at this from the point of view of the user of your app. Your user sees a 2Mbps (assuming you meant Mbps not MB/s) connection. That's a very narrow band for a Web server. Typically, We

I wouldn't trust Softlayer with my clients' data. Look at what happened to SimpleCDN and others. In a matter of a couple of days Softlayer pulled the plug on all their servers. SimpleCDN was erased from the CDN map. They used to have over 1

"twitter has servers dedicated to high-volume users without having to use urls/dns like that" That's why they need so many load balancers w/ failover: twitter.com has address 128.242.240.148 twitter.com has address 128.242.245.212 twitter.c

DNS is much easier to scale out than HTTP. By having full FQDN for users, you have the capability to easily scale out without needing a load balancer in front of say, threewords.me. So in your DNS zone you can tell it to route all accounts

It looks like it's already been moved to EC2 and switched to Varnish cache and Nginx for static files. I think the decision to tie the "user" view to the main FQDN ( http://threewords.me/joe ) will come back and bite hard if this project tu

You gotta love the marketing folks. The blog post has no substance besides the fact that they've hired Edgecast and branded it as their own CDN (ProCDN). Regards Joe

I'm open & willing to consider this as a possibility. In retrospect, I can think of many situations where I changed course even though I was convinced. But I can also think of many others where I kept pursing things (but not at the risk

It's running the Arc web server, which has its own implementation of the HTTP protocol. I don't think there's anything behind or in front of it. Probably not even Memcached. Think of the app serving HN as a framework. Here's how a "URL" ent

Congrats on the launch! Is there any reason you're running an outdated version of Nginx (0.7.65 vs 0.7.68 vs 0.8.54)? It's one major revision behind current and a few minor behind stable. Which brings me to a question I had lingering in my

Benchmark! That's how. Order the least amount of resources and then benchmark your app to see how well it's performing. If your goal is handle 100 req/s, then benchmark with that goal in mind. Your benchmark unit tests need to touch the who

This is a disgusting action from UK2/SL. If you promise 100TB of data transfer on 1Gbps, you have to keep your word (not matter what). Otherwise, don't venture in offering such deal. Essentially, they're kicking out the tail end of the "dis

Hi there, Keep in mind that writes will always be faster than reads thanks to cache write-back. This is because writes are asynchronous at the kernel and controller level. When your app writes a file, it indirectly writes it to the disk cac

If I may ask, what are your read and/or write patterns like (random, sequential, predictable, etc)? What's the typical read and/or write size like for your application? How much data are you dealing with? I understand you're set on a cloud-

Check out the anti-DDoS article we wrote up a few months ago. It uses a constellation of Nginx nodes to absorb the DDoS. The constellation acts the same way as a CDN without the geoIP awareness. The advantage of this approach is that instea

A bogus host will obviously not respond to the RST but the last router-hop that receives the RST will (per RFC/protocol specs). The response is destination unreachable via ICMP. The ICMP unreachable packet is cheap (non-persistent) and requ

Most likely, the initial Netcraft attempt to connect is met with a RST. Subsequent attempts are also met with the same RST. This is because the attempts are spaced out in time enough for the original ACL, permitting access, to be flushed. A
