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.
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.
At QCon London 2015 Phil Calcado shared lessons learnt from SoundCloud’s move from a monolithic to microservices architecture, and stated that the core requirements for building a microservice platform include developing capabilities for rapid provisioning, basic monitoring and rapid application deployment.
At the last QCon London, Michael Brunton-Spall, Technical Architect at the UK's Government Digital Service, expressed his views on how DevOps patterns are crucial to successfully operate microservices. Brunton-Spall identified the key ingredients to identify a microservice, explained how to build your first microservice and the necessary tools and practices to manage an ecosystem of microservices.
At QCon London 2015, Dave Farley proposed that although the state of software development has been suboptimal in the past, studies are revealing that the implementation of continuous delivery leads to considerable improvement. Farley stated that continuous delivery changes the economies of software development, and provides more rapid business idea validation and reduced defect rates.
Docker Inc., have released version 1.5 of the Docker application container runtime, which contains IPv6 support, read-only containers, access to container statistics, “named Dockerfiles” and a Docker image specification v1.0.0.
CoreOS have opened a pull-request to Docker which contains a proof-of-concept modification to enable Docker to run appc app container images (ACIs). At the same time CoreOS have also released a new version of Rocket that supports the native running of Docker images.
Amazon Web Services (AWS) have released an open source proof of concept scheduler driver that demonstrated how the Apache Mesos cluster manager could be integrated with the Amazon EC2 Container Service (ECS) preview.
