In 1998, Michael Kunze wrote an article for c't, a biweekly German computing magazine, hoping to demonstrate that free software could be an effective substitute for its commercial counterparts. In the article, he coined the acronym "LAMP" to describe an illustrative collection of available software - the Linux operating system; the Apache Web server; the MySQL relational database management system; and the Perl, Python, and/or PHP scripting languages - that could provide an end-to-end free computing environment. Kunze hoped that the acronym-loving IT community would remember LAMP in connection with the proposition that free software deserved serious consideration as an alternative to commercial software.
Seven years on, with Kunze's thesis well proven, the LAMP acronym has been co-opted by the marketing department of at least one of the LAMP constituents to stand for an altogether different proposition; that Linux, Apache, MySQL, and the "P" scripting languages should constitute the open source stack of interest when considering software alternatives. It's a proposition that is equally specious, insidious, and fatuous.
It's specious because, while it's initially plausible, it is ultimately wrong. Those open source components are well known, readily available, and work well together for many tasks, particularly for serving Web sites without update-intensive database requirements. However, LAMP's role as a merely illustrative stack of open source offerings is hardly ever acknowledged; in reality, each layer of the LAMP stack is fungible. No one layer was expressly designed to work with the others, and neither do any of them work better with the others than do alternatives. For example, the PostgreSQL and EnterpriseDB databases work just as well with "L," "A," and "P" as does MySQL. Similarly acceptable substitutions are, of course, available for each other layer in the stack.
As an aside, the "P" layer does stand as something of an exception, as three choices-Perl, Python, and PHP-are commonly admitted, but even here questions are raised: What happened to Ruby and all the others? What if Larry Wall's "Practical Extraction and Report Language" (a backronym, at that) had actually been "Gloria," as he is said to have considered? GLAMP, indeed.
The irony is that the LAMP shorthand is frequently encountered in open-minded discussions concerning open source alternatives to stacks of expensive commercial software. Open source advocates promoting LAMP actually do a disservice to their listeners by providing them with useful (i.e., LAMP is one choice) but incomplete (i.e., there are many choices) information.
What's insidious about the popular tendency to refer to LAMP as if it were the open source alternative to closed source technology stacks is that the notion is taking hold gradually, subtly, and harmfully. Each time this particular stack is tendered without explanation as a proxy for open source software, generally there's another opportunity for the two to be misidentified as synonyms. The danger is that this specific software combination will become so institutionalized that an enterprise finding one layer of LAMP unsuitable will end its inquiry, declaring that "the" open source stack cannot meet its needs. That's bad for Linux, bad for open source software, and bad for enterprises.
Finally, the notion that the LAMP constituents constitute the "official" or even "preferred" open source alternatives to commercial software is fatuous in the face of the open source ethos, which, among other virtues, is characterized by transparency and choice.
Kudos to Kunze for getting us started in the right direction. Now, it's time to elevate our discussion.

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
