However, there are three in-particular, that are designed to be highly flexible message queues for their own sake: Apache ActiveMQ ZeroMQ RabbitMQ Apache ActiveMQ seems to get the most press, but it appears to have some issues not losing messages. … So, without further ado…here is a reduction of a weeks’ worth of reading up on AMQP and how it works in RabbitMQ…and how to play with it in Python: Playing telephone There are four building blocks you really care about in AMQP: virtual hosts, exchanges, queues and bindings.

Coming soon…

Some folks hate to be offline, and some folks can't afford to be. I suppose I fit somewhere in between. About a month ago, I realized I was going to be doing some significant traveling…probably nowhere near a decent WiFi access point. Thus arose the question…how do you connect back to the office regardless of [...]

Tomorrow (05/28/2008) I'm giving a talk on moving to open storage (i.e. ethernet, OpenSolaris and SATA…in no particular order) at the Diocesan Information Systems Conference in San Antonio. It's a closed event, but here are the slides from the talk…including the talking notes which cover a lot more than I'll probably have time for:

It's nice when you boot an appliance and the web user interface doesn't look like it was designed by a guy who thought Jurassic Park and The Net were the pinnacle of UI design. The A10 Advanced Core OS (ACOS) has an incredibly polished look to the WebUI. Frankly, its beautiful. All chrome and glass so to speak…
 
Overall, the [...]

It's been nearly two years since we ventured into the wonderland of replacing our Alteon gear with the Sun N1216. It was a big risk because load balancers are interlaced tightly with our multi-phased mail logistics architecture. To say the least, we have not been disappointed. The Sun N1216 series is by far the best load balancer [...]

Currently, we're putting the N1400Vs into production and there were two odds and ends that came to mind that I wanted to mention:

No client/server settings per port! Hooray! The Alteons (even the 2424s) inherited from the Alteon AD4s and 184s the need to enable client and/or server processing per port. For those who are not [...]

The biggest toughest fish in the sea…and load-balancer on earth…
Might as well call it CryptoFish…
Up until this point, we've never had the pleasure of using SLB-based SSL-offload. We've just trudged along…scaling the ol' SSL proxies along with the app servers. While cost-effective, the customer doesn't get Speedy Gonzales latencies, and the number of [...]

First off, I have to give many deepest apologies to David C. in the Sun/Nauticus group who was kind enough to send us a pair of N1400Vs for demo purposes. They've been here longer than I care to own up to, waiting on me to demo them. Its definitely not been for lack of interest…but [...]

Just a quick note… When Sun engineers look at you like you've got the plague for mentioning Sun Cluster and Solaris Express in the same breath…there's a reason. The reason is that your breath is indeed infected with a plague…one that'll cause your Solaris Express instance to spew core dumps and kernel panics like a [...]
