When developing large complex systems and dealing with legacy code, organizations need to have systems in place to support integration and delivery. Modularization can help when agile is scaled with multiple teams that are working in parallel. It's not the framework or method that will do the job, but how your people will make it work to solve your problems says Hans Dekkers.
The software testing practices and mindset have radically changed since the early days of Agile and Lean. Software testing practices and mindset are an inseparable part of DevOps culture.
At QCon New York 2015, Paul Payne discussed a project at Nordstrom that required modifying and re-deploying a live application service within twenty minutes, which was made possible due to the use of Go-based microservices, Docker container technology, and a continuous delivery methodology.
Astrid Atkinson, director at Google, drew on their experiences over the last decade to present some rules and advice on engineering for the long term. The Velocity Conference 2015 attendees at Santa Clara learned that it's crucial to imagine that you're going to be wildly successful, that complexity mustn't be eliminated but managed and that the focus should be on scaling systems not teams.
Google have created a Kubernetes-based open source reference implementation that automates the building of custom Google Compute Engine VM images with Jenkins and Packer. The primary goal of this work is to demonstrate how to add image creation into a build pipeline for continuous delivery, and produce artifacts that may provide increased reliability and reduced speed of VM initialisation.
Capgemini are currently working on Apollo, an open source application platform built on top of the Apache Mesos cluster manager and Docker, which is designed to power next generation web services, microservices and big data platforms running at scale.
Forrester has come-up with a new definition of DevOps. Forrester has added an additional “S” for sourcing in the CALMS definition of DevOps. They believe that DevOps must be supported by a solid sourcing strategy to extend the ecosystem. This then brings them to the acronym of CALMSS.
New Relic has released a set of new features to its Software Analytics Platform. Service Maps is a real time visual map focused on services. Together with a tool for Docker monitoring, a database dashboard for NoSQL databases and an unified alerts platform, the company wants to reduce complexity in modern software architecture.
Lindsay Holmwood, Flapjack's creator, offers advice to enable fast, with quality, feedback loops and to support small, discrete changes. Holmwood asserts that to get quality feedback there are five main issues to think about: the CAP theorem; SLA definition; SLA validation; interfaces between services; data and infrastructure immutability.
Continuous Integration can help to find integration issues earlier and to visualize the status of the build to all involved. Integration problems can be detected at build-time in stead of run-time during testing and teams can get immediate feedback on changes that they made and on the impact on components that are developed by other teams.
Teams rarely consider success as a mode of failure, but not preparing for exceeding their goals can be just as dangerous as ignoring basic software and infrastructure needs. Mark Simms and Mark Souza discuss anti-patterns they've seen and some of the best ways to architect to win in spite of your own success.
Cisco is currently working on an open source ‘microservice-infrastructure’ project, which will support the continuous deployment of microservice-based applications, and is built upon technologies such as Mesos, Consul and Docker. Development is occurring primarily in the open, via the CiscoCloud Github account.
An interview with Yaniv Yehuda, Co-Founder and CTO of DBmaestro, about how they are doing agile development and using DevOps, how they implemented continuous delivery, on agile practices that turned out to be difficult to implement, and the benefits that they are getting for using agile and DevOps practices.
CoreOS has released Tectonic, a new product created from the aggregation of the CoreOS stack and the Google Kubernetes platform. Tectonic packages up different container technology and puts an UI on top of containers which includes a management console, an integrated registry and other tools to automate deployment.
PowerShell Tools for Visual Studio is a Visual Studio extension that brings the power of Visual Studio to PowerShell developers. Adam Driscoll, the original creator of this extension, got help from Microsoft over the past couple of months. The result is a new release, v3.0.108, offering 64-bit and remote session support, among other improvements.
