Load Balancing Digest

Coyote Point recently announced the release of their 8.0 Equalizer code for their load balancer/application delivery line.  Coyote Point was kind enough to hook me up with a preview release of the 8.0 code, and I loaded it up on a pair of e350si’s and walked it through its paces to see what’s changed.
Functionally speaking, [...]

I’m off on vacation (yes, I know, during Interop) starting today, and I shall return in May to regale you with more musings of the load balancer realm.
In my absence, I have programmed this here Interweb machine to automatically post articles on a regular basis that I have prepared in advance. Here is what you [...]

I deal with regex enough to need to know a beginning to intermediate level of knowledge, but I don’t use it enough to be able to form regex statements without thinking. Or in load balancing terms, it’s not burned into my brain ASIC. Every time I do regex, I’m doing it purely in software.
So [...]

Eight years ago I wrote an article called “It’s Always The Load Balancer“, and eight years later, that’s still the case. But despite being the undeserved scape-goat of an infrastructure’s (and society’s) ills, there are a few things that actually are the load balancers fault (and those who charged with their administration).

Just like any other industry publication, these reviews will be arranged with the individual vendors, and no money will be accepted from the vendors for the review. (Unless the amount of money will completely fill up a suitcase with [...]

A great little tool for Windows systems is the command “netstat -e“. I shall explain.
A bane of of the network is the insidious duplex mismatch issue. This is when, through either autonegotion or auto-detection, one end of two cabled devices think the link is full duplex, and the other end thinks it is [...]

Here’s one of the trickier issues that can sometimes come up with load balancing. You’ve setup load balancing for a couple of application servers, and at least on a TCP level, things appear to be working. However, the app guys are complaining that the load balancer is doing something weird, and when you [...]
