    Web Application Firewall: What’s In A Name?

    In my recent review of KEMP’s new LoadMaster software, which includes Web Application Firewall capabilities, Ofer Shezaf (from breach.com) had this to say in the comments section: Systems supporting only snort rules and lacking a positive security model are not usually not considered a web...

    HTTP Analyzers and ASICs

    Greetings from Italy.  I’m here dealing with ASICS of a different kind (as in the shoes), specifically the 23rd ASICS Venice Marathon.  I was in no danger of winning it, but I did complete it in 4 hours, 25 minutes (my 3rd Marathon). Other than...

    The Web Server Is Dead: Long Live The Application Server

    I dare say there are very few web servers left on the Internet. I think you’d have to spend a considerable amount of time trying to actually find one. Now, given that you’re reading this on a web server, and there are obviously millions of...

    Where Have All The Suns Gone?

    I got an newsletter email from Sun the other day, basically offering to buy me dinner. No, Sun wasn’t trying to get frisky with me, rather they were trying to entice me to get certified in Solaris 10. (Although, thinking about it, that may just...

    A Market By Any Other Name…

    The great thing about inventing markets is that you get to name them. I’ve recently named the Enterprise (F5/Citrix) market the “Premium” market, and the SMB market (KEMP/Barracuda/Coyote Point) market the “budget market”. OK, so I didn’t invent them. And I wasn’t the first to...

    A Load Balancer By Any Other Name…

    Recently, I posed a question on the mailing list: What do you call these devices that balance load and possibly do all this other stuff? The reaction to such a seemingly innocuous subject was actually the most impassioned discussion the mailing list has seen in...

    Magic Quadrants

    Someone mentioned the Gartner magic quadrant on the mailing list, so I looked for the most recent load balancing/application delivery doohicky quadrant diagram, and here it is. While this is a pretty good diagram of the premium market, I have a few disagreements with it....

  • A Tale of Two Markets

    A Tale of Two Markets

    In the beginning, there was but one load balancing/application delivery market, and it was good. A couple of years and one dot-com meltdown later and somehow, unknown to many, we have two very distinct load balancer markets. The first market, the enterprise or “premium” market,...
