DevOps can be succinctly defined as a mindset of molding your process and organizational structures to promote
software quality attributes most important to your organization
As I have discussed in previous posts on DevOps at Amazon and software quality in DevOps, while DevOps is often approached through practices such as Agile development, automation, and continuous delivery, the spirit of DevOps can be applied in many ways. In this blog post, I am going to look at another seminal case study of DevOps thinking applied in a somewhat out-of-the-box way: Netflix.
This post is the latest installment in a series aimed at helping organizations adopt DevOps.
Tools used in DevOps environments such as continuous integration and continuous deployment speed up the process of pushing code to production. Often this means continuous deployment cycles that could result in multiple deployments per day. Traditional security testing, which often requires manually running multiple tests in different tools, does not keep pace with this rapid schedule. This blog post introduces a tool called Gauntlt, which attempts to remedy this issue.
When Agile software development models were first envisioned, a core tenet was to iterate more quickly on software changes and determine the correct path via exploration--essentially, striving to "fail fast" and iterate to correctness as a fundamental project goal. The reason for this process was a belief that developers lacked the necessary information to correctly define long-term project requirements at the onset of a project, due to an inadequate understanding of the customer and an inability to anticipate a customer's evolving needs. Recent research supports this reasoning by continuing to highlight disconnects between planning, design, and implementation in the software development lifecycle. This blog post highlights continuous integration to avoid disconnects and mitigate risk in software development projects.
"Software security" often evokes negative feelings among software developers since this term is associated with additional programming effort and uncertainty. To secure software, developers must follow a lot of guidelines that, while intended to satisfy some regulation or other, can be very restricting and hard to understand. As a result a lot of fear, uncertainty, and doubt can surround software security. This blog posting describes how the Rugged Software movement attempts to combat the toxic environment surrounding software security by shifting the paradigm from following rules and guidelines to creatively determining solutions for tough security problems.

Jane Orsulak and Julie Kent kicked off the experience-presentation session on SATURN's final day by talking about "System Characterization: An Approach to Modernizing Disparate Legacy Systems." In this presentation, they gave a summary of some of the training that soldiers have to go through, such as live training and virtual training.
