Puppet Labs’ latest version of Puppet Enterprise - version 2015.2 - includes new features like node graph visualization, inventory filtering, and a VMware vSphere module. It provides users with major enhancements of the Puppet Language and an updated web UI. InfoQ spoke with Michael Olson, Senior Product Marketing Manager at Puppet Labs .
At the fifth ‘Agile on the Beach’ conference, held in Cornwall, UK, several leading practitioners of agile software delivery presented the state-of-the-art and emerging trends within this domain. Key messages included the need for the more rigorous use of the scientific method throughout the software delivery lifecycle, and the benefits provided by applying agile principles to product development.
At QCon San Francisco, we offer two days of workshops (Nov 19-20). Workshops focus on developing the technical skills that leverage technologies you heard about from our expert practitioners during the conference sessions. Here is a glimpse at some of the experts you can learn from QCon SF ‘15 workshops.
The Puppet Labs: State of DevOps Report 2015 shows the current DevOps trends in IT, comparing the high and low performers in terms of deployment success and stability, and observing the link between architecture and developer productivity.
HashiCorp have publicly released Atlas, a commercial platform that unites their open source tools for development and operations to create a version control system for infrastructure management. Atlas integrates HashiCorp’s Vagrant, Packer, Terraform, and Consul tooling, with the primary goal of promoting ‘automation, audit and collaboration on infrastructure changes’ across the modern datacenter.
Adrian Cockcroft's devopsdays Amsterdam 2015 keynote addressed how CIOs' key goals - align IT with business, develop products faster, avoid security breaches - are attained through the adoption of DevOps practices and Continuous Delivery with containerized microservices. But managing microservices poses new challenges. Cockcroft proposes simulation as a solution to some of those challenges.
At QCon New York 2015, Mitchell Hashimoto discussed how tools such as a HashiCorp’s Terraform and Consul could be utilised to orchestrate infrastructure provisioning and application lifecycle management of cloud and container-based applications, with the ultimate goal of safely delivering software systems at scale.
The discussion on ITIL vs. DevOps is a common one. There are different views: ITIL and DevOps have different mindsets; ITIL and DevOps are compatible; they are different but both have their place in the IT department. Charles Betz, member of the Open Group IT4IT Forum, argues that their principles are at odds. ITIL is trapped in a phased workflow mindset. DevOps embraces lean product management.
Steve Smith presented at Devoxx UK 2015 how Continuous Delivery is performed within Atlassian. After the talk, we had the chance to discuss further details of his presentation and ask him a few questions.
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.
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.
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.
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.
