#f5 There’s a new brand of Chili in town. I don’t usually talk a lot about F5 specific solutions, but since we’re the only ones doing this (so far), the contents of this blog are F5 specific. Though this needs to be industry standard. So, you’re yearning for some chili. That’s understandable, this time of year is when those of us from the US midwest think of chili, because it’s good hunting season food, and it both fills you and warms you up. So grab a handful of hamburger and stuff it in your mouth, then grab...
(Booming voiceover voice); Are you running the same tired old network tools? Does your network staff have to administer security and load balancing for each and every application? Do you find application analysts and owners show a growing frustration with the network team’s response times due to overloading? Well get in there and fix that network! Get the tools that you need to make your network more application friendly, reduce fatigue amongst your network staff, and give application owners more control of their applications! That was, of course, a joke poking fun at both the way we run...
There was a time when application developers worried only about the hardware they were developing the application for. Those days passed a good long while ago, and then AppDev’s big concern was the OS the application was being developed for. But the burgeoning growth of the World Wide Web combined with the growth of Java and Linux to drive development out of the OS and into the JVM. Then, the developer focused on the JVM in question, or in many cases on the interpreted language interfaces – but not the OS or hardware. For our purposes I...
We’ve all had that chilling moment when the gate attendant at the airport comes over the loudspeaker, and doing her best Charlie Brown’s Teacher imitation, announces “Jursim Puzzling vlordid Netting, gollink dummole Neptune.” (This flight is in an oversold situation, we’re looking for volunteers…). While we could discuss the causes and solutions to this being an all-too-frequent event in the daily operation of airlines, for the purposes of this blog, let’s talk about the back end. The problem on the back end is, quite simply, that the plain cannot be expanded to handle the burden demanded of it. That...
My older children, like most kids in their age group, all played with or collected Pokemon cards. Just like I and all of my friends had GI Joes and discussed the strengths and weaknesses of Kung-fu grip versus hard hands, they and all of their friends sat around talking about how much cooler their current favorite Pokemon card was compared to all of the others. We let them play and kept an eye on how cards were being passed about the group (they’re small and tend to walk off, so we patrolled a bit, but otherwise stayed out of...
In a couple of unrelated bouts of cleaning – one to show The Toddler my Boy Scout sash, which required going through boxes in the basement until I found it, and the other attempting to dig a toy out from under the stove, which required pulling the stove out from the wall and cleaning under it in one of those scenarios where once you’ve seen it, you have to clean it, I found some unexpected bits. In the box that contained my Boy Scout sash, I found the tire pressure gauge that I’ve been vaguely looking for over the...
Every once in a while, I like to step back a bit and write for those who haven’t been in the field for a zillion years. For starters, it helps refresh the pool of information out there for people trying to research something they haven’t done before. It helps a lot that I enjoy sharing my knowledge, so writing such a blog is like “non-work”. Since I’m gearing up for some holiday time, this seemed like a great time to do just such an article, so I cast about and TCP optimizations came to mind. A lot has...
I’ve been pondering another installment in my Load Balancers For Developers series revolving around recent changes in the market that drive a trend toward availability of Virtual Load Balancers, giving developers an idea of what, when, where, and why they might take advantage of a virtual load balancer. There’s a lot of information floating around out there, and one of the things this blog will do is include some development-specific links in the list of related articles at the end. The primary goal of this article is to help you understand where and why, but since I try not to...
There is one little thing you’re missing from your IT budget. While it impacts manpower most of all, you’ll be feeling it throughout your budget, and see signs of it in other departments as well. You should plan for it, because it is nearly a guarantee that it will continue to impact your budgeting for the next year or so. It’s not SOA. SOA had its day in the sun, and though Cloud will give it a little bit more, it is pretty much baked into the budgets of those organizations using it, and not even on the radar...
For me, as a developer, the big differentiator between a Load Balancer and an Application Delivery Controller (ADC) is the ability to use code to help manage how my application and the network interact. Some things you just can’t do from your application because by the time your application knows it should be doing something, it’s too late, some things are just easier done on a network device (yeah, or a VM pretending to be a network device if your name is Izzy ;-)).
Note that by far my experience is with F5 products, it’s my job to know what they’re...
