"The big problems are where people don't realize they have one in the first place." - Edward Deming, patron saint of DevOps.
Clarity on a Big Problem
In part one of this series, "Rugged DevOps: Survival is Not Mandatory", I shared news that 1 in 16 open source and third-party components downloaded last year included a known vulnerability. That may not seem like too many until you realize the average company downloads well over 200,000 components annually. These components are electively downloaded by development teams, often unaware of the vulnerabilities that come with them.
Manually reviewing every component you desire to download and use is out of the question... nobody has the time or resources for that. To do it right, would require dedicating 2 - 4 hours of research per component - and your organization consumes thousands of unique components each year.
There is an easier (and free) way to understand if your repository contains components with known security vulnerability or license risks. Every one of the 60,000 active Nexus repository manager installations out there comes with a feature called the Repository Health Check. If you have a big problem, the health check will let you know; if your repo is free of vulnerable and risky components, you will learn that too.
Guarding the Front Door, The House, and Back Door
Protecting the Front - Let's say you turn on the Repository Health Check feature for your Nexus repository managers and the report reveals presence of undesirable components. Your organization may want to explore the new Nexus Firewall offering that provides a "cyber guard" at the front door of your repository to prevent future downloads of known vulnerable, risky, or outdated components.
Protecting the Inside - We often say that components age like milk and not wine. Yes, we all understand that a component that is good today, may go bad tomorrow. Therefore, you can continue to use the Repository Health Check reports to automatically audit your repositories for any changes over time.
Protecting the Back - Additionally, for those of you utilizing staging repositories in your configurations, Nexus Firewall can help analyze your release candidates. The staging suite (available in the commercial version of Nexus Repository) allows an organization to create a temporary staging repository and to manage the promotion of components from a staging repository to a release repository. This ability to create an isolated, release candidate repository that can be discarded or promoted makes it possible to support the decisions that go into certifying a release. This enables you to better control the exact set of binaries that will ultimately be released.
When coupled with the Nexus Firewall solution, every component in the staging repository can be assessed for known security vulnerabilities, outdated/undesirable versions, or risky licenses. Used in this manner, Nexus Firewall not only protects your front door upon initial download of the components, it also guards your back door prior to releases going out.
Solving Big Problems
As Deming suggested, to solve a big problem, you first need to realize you have one. Hopefully the Repository Health Check feature mentioned early in this post can shed some light on what's happening inside your SDLC and software supply chain.
We all have a software supply chain that feeds components into our repository managers and application development lifecycles. With better visibility to the components we are using, we can all deliver better software, even faster.
While this story covers only one aspect of Rugged DevOps, there is much more to be learned about the subject. One of the best papers I have read recently comes from Amy DeMartine and Kurt Bittner at Forrester Research, entitled "The Seven Habits Of Rugged DevOps: Strengthen Cybersecurity Using DevOps Culture, Organization, Process, And Automation" (registration is required to download, but it's worth it).

Virtualization over the past years has become a key strategy for IT to acquire multi-tenancy, increase utilization, develop elasticity and improve security. And virtual machines (VMs) are quickly becoming a main vehicle for developing and deploying applications. The introduction of containers seems to be bringing another and perhaps overlapped solution for achieving the same above-mentioned benefits. Are a container and a virtual machine fundamentally the same or different? And how? Is one technically superior to the other? What about performance and security? Does IT need either one, or both?

Keeping pace with advancements in software delivery processes and tooling is taxing even for the most proficient organizations. Point tools, platforms, open source and the increasing adoption of private and public cloud services requires strong engineering rigor - all in the face of developer demands to use the tools of choice. As Agile has settled in as a mainstream practice, now DevOps has emerged as the next wave to improve software delivery speed and output. To make DevOps work, organizations must focus on what is most relevant to deliver value, reduce IT complexity, create more repeatable agile-based processes and leverage increasingly secure and stable, cloud-based infrastructure platforms.

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ability. Many are unable to effectively engage and inspire, creating forward momentum in the direction of desired change. Renowned for its approach to leadership and emphasis on their people, organizations increasingly look to our military for insight into these challenges.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die.

In his Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, will explore the ways that Nutanix technologies empower teams to react faster than ever before and connect teams in ways that were either too complex or simply impossible with traditional infrastructures.

All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the works because of misaligned incentives.
