Douglas C. Schmidt In the first half of this year, the SEI blog has experienced unprecedented growth, with visitors in record numbers learning more about our work in big datasecure coding for Androidmalware analysisHeartbleed, and V Models for Testing. In the first six months of 2014 (through June 20), the SEI blog has logged 60,240 visits, which is nearly comparable with the entire 2013 yearly total of 66,757 visits. As we reach the mid-year point, this blog posting takes a look back at our most popular areas of work (at least according to you, our readers) and highlights our most popular blog posts for the first half of 2014, as well as links to additional related resources that readers might find of interest.

C. Aaron Cois To maintain a competitive edge, software organizations should be early adopters of innovation. To achieve this edge, organizations from Flickr and IBM to small tech startups are increasingly adopting an environment of deep collaboration between development and operations (DevOps) teams and technologies, which historically have been two disjointed groups responsible for information technology development. “The value of DevOps can be illustrated as an innovation and delivery lifecycle, with a continuous feedback loop to learn and respond to customer needs,” Ashok Reddy writes in the technical white paper, DevOps: The IBM approach. Beyond innovation and delivery, DevOps provides a means for automating repetitive tasks within the software development lifecycle (SDLC), such as software builds, testing, and deployments, allowing them to occur more naturally and frequently throughout the SDLC. This blog post, the second in our series, presents a generalized model for automated DevOps and describes the significant potential advantages for a modern software development team.

An Introduction to DevOps

Aaron CoisAt Flickr, the video- and photo-sharing website, the live software platform is updated at least 10 times a day. Flickr accomplishes this through an automated testing cycle that includes comprehensive unit testing and integration testing at all levels of the software stack in a realistic staging environment. If the code passes, it is then tagged, released, built, and pushed into production. This type of lean organization, where software is delivered on a continuous basis, is exactly what the agile founders envisioned when crafting their manifesto: a nimble, stream-lined process for developing and deploying software into the hands of users while continuously integrating feedback and new requirements. A key to Flickr’s prolific deployment is DevOps, a software development concept that literally and figuratively blends development and operations staff and tools in response to the increasing need for interoperability. This blog post, the first in a series, introduces DevOps and explores its impact from an internal perspective on our own software development practices and through the lens of its impact on the software community at large.
