Today: What DevOps is not + follow the money

1. Replace the project paradigm The problems caused by using the project paradigm to delivering software systems are severe, says Jez Humble. They lead to complex, heterogeneous production environments that are hard to change or even keep running. Moreover, bundling work into projects combines low-value features with high-value features in order to deliver the maximum viable product that is the inevitable result of the large-batch death spiral. Strong words. So what should we do instead? 2. What does your site cost? How much are users paying to access your site on mobile? Here's a neat tool fromTim Kadlec that will let you know. Keep in mind, these are best-case scenarios. 3. Infrastructure as code The latest Early Release title from O'Reilly,Infrastructure as Code, explains how to take advantage of technologies like cloud, virtualization, and configuration automation to manage IT infrastructure using tools and practices from software development. Author Kief Morris uses patterns and ideas that have been adopted from software development, especially Agile concepts, and brought into the IT Ops world as part of the DevOps movement.

TLS and HTTP/2 Transport Layer Security (TLS) isn't perfect, but Daniel Haxx argues that TLS and HTTPS are the best way we currently have to secure websites. Why not mandatory TLS? he asks. 5. The value of preloading Preloading, or "predictive browser caching" is a web performance optimization technique that loads resources (e.g. image files) needed by the next page in a user's path on the site, before the user gets to that page. Kent Alstad makes the case for preloading based on a battle-tested wpo treatment. 6. Automate code to adapt to customer demand quickly Part 3 of O'Reilly's 6-part "Coded Business" training series brings Facebook production engineer Phil Dibowitz to discuss the dramatically accelerating cycle of getting features/products/release to users, and collecting and acting on user feedback. Join Phil to learn what IT must do to make coded business a reality today, elements of scale, and the benefits of automation, no matter how large or complex your organization is.

But what keeps Patrick Debois up at night? Jason Hand gets the answer to this question and more in this DevOps interview with Patrick Debois. 8. What DevOps is not In the unending debate about what DevOps is, isn't, and if it exists at all, another programmer shares the tale of his journey into DevOps and his ultimate rejection of it. 9. New at Velocity: hands-on training For the first time, Velocity will offer full-day, intensive training on topics such as Distributed Systems, CDNs, Effective DevOps, and High Performance Organizations. From tutorials to full-day training sessions, the first day of Velocity is packed with practical and actionable learning. Velocity happens May 27-29 in Santa Clara, CA. Consider adding training to the conference package or attend a one-day training course on its own. Ticket prices will go up in just a few weeks.  See prices & discounts→ 10. Public versus private cloud Prices are dropping fast and public clouds are looking more attractive than ever. Why, then, did Walmart just reveal that they are building an enormous private cloud? Price isn't enough to justify a shift to a public cloud, argues Jim Stogdill. 11. Follow the money...to enterprise apps One of the most intriquing findings from a recent survey of 8,000 mobile developers was that most of them aren't earning much from their apps. So where is the money? According to Kevin Casey, 43% of enterprise-focused developers earn over $10,000 per month from applications, compared with just 19% of consumer-oriented apps. Casey shares insights on this and other financial lessons for mobile app developers. 12. Running Agile programs at scale While there are now several frameworks for running large-scale agile programs, the most popular suffer from the flaw that they take agile teams and embed them within a more traditional program management paradigm. Join Jez Humble in this free webcast as he presents the principles behind a Lean/Agile paradigm that works at scale using the inventiveness and passion of people throughout your organization. This is part 2 of the Lean Enterprise Live Training series. Thursday, March 19 at 10am PT Reserve your spot → 13. Inlining critical CSS for first-time visits The idea is that you can give a massive boost to the perceived performance of the first page load on a site by putting the most important CSS in the head of the page. Then you cache the full stylesheet. For subsequent visits you only ever use the external stylesheet. Jeremy Keith documents his experience with inlining critical CSS.
