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...

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...

"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...

The workflow of deploying code is almost as old as code itself. There are many use cases associated with the deployment process, including evaluating resource requirements, designing a production system, provisioning and configuring production servers, and pushing code to name a few. In this blog post I focus on a use case for configuring a remote server with the packages and software necessary to execute your code....

In a computing system, a context switch occurs when an operating system stores the state of an application thread before stopping the thread and restoring the state of a different (previously stopped) thread so its execution can resume. The overhead incurred by a context switch managing the process of storing and restoring state negatively impacts operating system and application performance. This blog post describes how DevOps ameliorates the negative impacts that "context switching" between projects...

The DevOps movement is clearly taking the IT world by storm. Technical feats, such as continuous integration (CI), comprehensive automated testing, and continuous delivery (CD) that at one time could only be mastered by hip, trendy startups incapable of failure, are now being successfully performed by traditional enterprises who have a long history of IT operations and are still relying on legacy technologies (the former type of enterprises are known in the DevOps community as...

When building and delivering software, DevOps practices, such as automated testing, continuous integration, and continuous delivery, allow organizations to move more quickly by speeding the delivery of quality software features, that increase business value. Infrastructure automation tools, such as Chef, Puppet, and Ansible, allow the application of these practices to compute nodes through server provisioning using software scripts. These scripts are first-class software artifacts that benefit from source code version control, automated testing, continuous integration,...
