How to Stop Running the Project Gauntlet of Doom with DevOps

RedHat puppetizes its infrastructure to reduce inefficiency and streamline deployment

I could cite various studies, pundits, and research to prove that automation improves the overall success rates of continuous deployment efforts, mitigates outages caused by human error and misconfiguration, and generally makes the data center smell minty fresh, but we already know all of that. It's generally understood that there is a general need for devops, for continuous deployment and lifecycle management systems enabled by frameworks like Puppet.

What we don't often consider is that the process of "puppetizing" production (and pre-production) environments affords organizations the opportunity to re-evaluate existing network and application architecture and eliminate inefficiencies that exist there, as well. Many an architecture has been built upon legacy application network infrastructure, for example, that cannot be – easily or otherwise – puppetized and thus serves as an impediment to realizing the full benefits of operational automation.

Sure, you could automate everything but those components that can't be integrated, but that leaves open the possibility for misconfiguration, for fat-finger errors, for fragmentation of ownership that is often the source of delays in moving releases through various environments and into production. RedHat, for example, maintains 4-7 pre-production environments through which it used to take 2-6 weeks to cycle a new release. Part of that time was caused by what RedHat veteran Bret McMillan called the "Project Gauntlet of Doom", which required collaboration across an increasingly fragmented set of groups responsible for managing the manual configuration of various infrastructure components – both hardware and software.

What the fine folks at RedHat discovered when they decided to puppetize their environments to eliminate the fragmentation was a great deal of inefficiency in the existing architecture. Multiple tiers of proxies performing fairly standard application networking functions: SSL termination, header manipulation, compression, URL rewrites and redirects and, of course, load balancing. Approximately 10% of the virtual machines in the infrastructure were performing what RedHat considered "low business value" functions – primarily because business (and end-users) don't directly realize the impact of such services, only the end-result of performance, security and availability.

What they found was that they could (1) consolidate 3 layers of services, (2) puppetize their entire environment, and (3) eliminate service-ip sprawl caused by the growing demands on IP addresses required to scale out its proxy layers. In other words, the desire for process automation through DevOps led to a streamlined, more efficient delivery architecture that benefitted operations, customers, and the business.

Because BIG-IP could provide an integrated service platform upon which multiple application-layer services could be deployed, the need for multiple layers of proxies and load balancers was eliminated, reducing the number of devices through which traffic had to traverse. Performance improved, as did the consistency of operations both by providing a common, integrated platform management interface at the BIG-IP for all application network layer services as well as through Puppet for configuration and continuous deployment management.

It's a win-win that effectively eliminates the need to run the Project Gauntlet of Doom during release cycles because Puppet automates the processes and eliminates the manual collaboration previously required. The end result is faster … everything, across the board.

A presentation from PuppetConf 2012, "Managing F5 LTM with Puppet - Matthew Carpenter and Bret McMillan of Red Hat" is available in video format, including greater detail and color commentary.

Happy Automating!

As the software delivery industry continues to evolve and mature, the challenge of managing the growing list of the tools and processes becomes more daunting every day. Today, Application Lifecycle Management (ALM) platforms are proving most valuable by providing the governance, management and coordination for every stage of development, deployment and release. Recently, I spoke with Madison Moore at SD Times about the changing market and where ALM is headed.
In a crowded world of popular computer languages, platforms and ecosystems, Node.js is one of the hottest. According to w3techs.com, Node.js usage has gone up 241 percent in the last year alone. Retailers have taken notice and are implementing it on many levels. I am going to share the basics of Node.js, and discuss why retailers are using it to reduce page load times and improve server efficiency. I’ll talk about similar developments such as Docker and microservices, and look at several compani...
From the conception of Docker containers to the unfolding microservices revolution we see today, here is a brief history of what I like to call 'containerology'. In 2013, we were solidly in the monolithic application era. I had noticed that a growing amount of effort was going into deploying and configuring applications. As applications had grown in complexity and interdependency over the years, the effort to install and configure them was becoming significant. But the road did not end with a ...
The goal of any tech business worth its salt is to provide the best product or service to its clients in the most efficient and cost-effective way possible. This is just as true in the development of software products as it is in other product design services. Microservices, an app architecture style that leans mostly on independent, self-contained programs, are quickly becoming the new norm, so to speak. With this change comes a declining reliance on older SOAs like COBRA, a push toward more s...
Small teams are more effective. The general agreement is that anything from 5 to 12 is the 'right' small. But of course small teams will also have 'small' throughput - relatively speaking. So if your demand is X and the throughput of a small team is X/10, you probably need 10 teams to meet that demand. But more teams also mean more effort to coordinate and align their efforts in the same direction. So, the challenge is how to harness the power of small teams and yet orchestrate multiples of them...
Many private cloud projects were built to deliver self-service access to development and test resources.

Much of the value of DevOps comes from a (renewed) focus on measurement, sharing, and continuous feedback loops. In increasingly complex DevOps workflows and environments, and especially in larger, regulated, or more crystallized organizations, these core concepts become even more critical. In his session at @DevOpsSummit at 18th Cloud Expo, Andi Mann, Chief Technology Advocate at Splunk, will show how, by focusing on 'metrics that matter,' you can provide objective, transparent, and meaningfu...
In the world of DevOps there are ‘known good practices’ – aka ‘patterns’ – and ‘known bad practices’ – aka ‘anti-patterns.' Many of these patterns and anti-patterns have been developed from real world experience, especially by the early adopters of DevOps theory; but many are more feasible in theory than in practice, especially for more recent entrants to the DevOps scene. In this power panel at @DevOpsSummit at 18th Cloud Expo, moderated by DevOps Conference Chair Andi Mann, panelists will dis...

The notion of customer journeys, of course, are central to the digital marketer’s playbook. Clearly, enterprises should focus their digital efforts on such journeys, as they represent customer interactions over time.

The challenge arises when EAs consider the context of the customer journey in the overall architecture as well as the architectural elements that make up each...
In 2006, Martin Fowler posted his now famous essay on Continuous Integration. Looking back, what seemed revolutionary, radical or just plain crazy is now common, pedestrian and "just what you do." I love it. Back then, building and releasing software was a real pain. Integration was something you did at the end, after code complete, and we didn't know how long it would take. Some people may recall how we, as an industry, spent a massive amount of time integrating code from one team with another...
Admittedly, two years ago I was a bulk contributor to the DevOps noise with conversations rooted in the movement around culture, principles, and goals. And while all of these elements of DevOps environments are important, I’ve found that the biggest challenge now is a lack of understanding as to why DevOps is beneficial. It’s getting the wheels going, or just taking the next step. The best way to start on the road to change is to take a look at the companies that have already made great headway ...
If there is anything we have learned by now, is that every business paves their own unique path for releasing software- every pipeline, implementation and practices are a bit different, and DevOps comes in all shapes and sizes. Software delivery practices are often comprised of set of several complementing (or even competing) methodologies – such as leveraging Agile, DevOps and even a mix of ITIL, to create the combination that’s most suitable for your organization and that maximize your busines...
Digital means customer preferences and behavior are driving enterprise technology decisions to be sure, but let’s not forget our employees.
