Load Balancing For Developers
The Load Balancing For Developers Series!
#F5 DevOps – Managers need to make use of existing technology and adopt culture change. It is entertaining to read all that is currently being written about DevOps. Having been a developer, a development manager, an operations manager, and even a CTO, I can attest to the fact that the “throw it over the wall” syndrome is real, and causes real problems for everyone involved. That is about where my agreement with the current round of pundits ends. The thing is that they talk like there is some fundamental technological reason why DevOps isn’t happening. That’s...
Developers are a great lot of folks, people who spend their day trying to do the impossible with bits for a customer base that is, by and large, impossible to satisfy. When the bits all line up correctly, the last line of code has been checked in, and the nightly compile accepted for deployment, then they get to sit back, relax for five minutes, and start over again. If this makes you think it’s not a great life, then you should live it. Developing gives instant feedback. No matter how unhappy users can be, fixing that nagging bug you’ve...
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...
There is a theory in traditional military strategy that goes something along the lines of “take land, consolidate your gains, take more land…” von Moltke the Elder found this theory so profound that he suggested a defender could trade land for time – advice that Russia managed pretty well in The Great Patriotic War (known in the west as World War II), and German General Kesselring practiced against the allies in Italy during the same war. By giving up land, the enemy is forced to occupy it before they can begin forward movement again, buying you time to build...
It has been a while since I wrote a Load Balancing for Developers installment, and since they’re pretty popular and there’s still a lot about Application Delivery Controllers (ADCs) that are taken for granted in the Networking industry but relatively unknown in the development world, I thought I’d throw one out about making your security more resilient with ADCs. For those who are just joining this series, here’s the full list of posts I’ve tagged as Load Balancing for Developers, though only the ones whose title starts with “Load Balancing for Developers” or “Advance Load Balancing for Developers”...
On occasion I have talked about military force multipliers. These are things like terrain and minefields that can make your force able to do their job much more effectively if utilized correctly. In fact, a study of military history is every bit as much a study of battlefields as it is a study of armies. He who chooses the best terrain generally wins, and he who utilizes tools like minefields effectively often does too. Rommel in the desert often used Wadis to hide his dreaded 88mm guns – that at the time could rip through any tank the British...
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...
