One funny thing about DevOps is that it is often touted that constant, on-the-fly changes are the way of the future in operations, and DevOps enables those changes. While this sounds really good, and some organizations are actually doing this type of DevOps, I think it is time that, for the enterprise, we strongly question that premise. While it is really very cool to think about moving an entire web server from a farm to the cloud with just a script, upgrading a system while it’s hot, or spinning up more instances of a server without having to configure anything, I propose that, for the average enterprise, it is simply not necessary. I’m working on a test automation project that is being implemented for a generally available library. In this case, test automation gives standardized testing with standardized reports for those who are going to use the library to r... (more)

All-Consuming, All-Confusing

Ask two politically opposed people in any given country about the causes of the country’s problems, and guess what? Each will give you an answer filtered through their world-view. Through what they know, and what they believe. That is not to say one is right and one is wrong, both simply see things in the manner their background and experiences tell them is right. We definitely live in interesting times. Server virtualization has just about reached saturation, application development is going through a wide range of changes from the return of automated testing to continuous integr... (more)

A Rose by Any Other Name - Appliances Are More Than Systems

One of the majors Lori and my oldest son is pursuing is in philosophy. I’ve never been a huge fan of philosophy, but as he and Lori talked, I decided to find out more, and picked up one of The Great Courses on The Philosophy of Science to try and understand where philosophy split off from hard sciences and became irrelevant or an impediment. I wasn’t disappointed, for at some point in the fifties, a philosopher posed the “If you’re a chicken, you assume when the farmer comes that he will bring food, so the day he comes with an axe, you are surprised” question. Philosophers know t... (more)

v.10 - iSessions in the Cloud (or a remote data center, you choose)

Well, I’ve covered the basics of iSessions – a secure, optimized tunnel between two BIG-IPs – so now it’s time to talk about usefulness, both today and going forward. Since iSessions are an infrastructure issue, the following works for redundant data centers also, assuming they have BIG-IPs in them, it’s just that cloud is the buzzword du-jour, and there’s actually a teentsy bit more benefit to using them for the cloud. First off, I assume that your cloud vendor has BIG-IPs (that is a safe assumption as of today), but you’re living in the real world, check with them first, there... (more)

Bare Metal Blog: Throughput Sometimes Has Meaning

Knowing what to test is half the battle. Knowing how it was tested the other. Knowing what that means is the third. That’s some testing, real clear numbers. In most countries, top speed is no longer the thing that auto manufacturers want to talk about. Top speed is great if you need it, but for the vast bulk of us, we’ll never need it. Since the flow of traffic dictates that too much speed is hazardous on the vast bulk of roads, automobile manufacturers have correctly moved the conversation to other things – cup holders (did you know there is a magic number of them for female pu...
