At the London Microservice User Group July meetup, Kai Davenport presented a live demonstration of ClusterHQ’s Flocker v1.0 container data volume manager tool migrating a Docker storage volume between multiple containers running within a Docker Swarm.
Only 38% of IT professionals use containers in production environments, according to a recent survey. ClusterHQ, which ran the survey of the current state of container usage and adoption, also concludes that 73% of respondents are running containers in a VM environment.
An interview with Ivan Kusalic, Software/DevOps engineer at Nokia HERE in Berlin, about why they decided to apply DevOps, how DevOps has changed their way of working, which benefits they are getting, and the challenges that they had and how they dealt with them when development and operations became one team. Kusalic also gives some advice for applying DevOps with teams.
David Mytton, CEO at Server Density, shared with the devopsdays Amsterdam 2015 crowd how they handle incidents and outages. The process is grounded on a key set of principles: frequent public updates; exhaustive logging of the response activities; team effort and effective escalation. Server Density draws a lot of inspiration from the aviation industry, renowned for its safety procedures.
Docker Inc, have released a new version of their core container runtime, Docker Engine 1.7.0, and updated versions of the supporting toolchain, Docker Compose 1.3, Docker Swarm 0.3 and Docker Machine 0.3. Highlights include the availability of a nightly built ‘Docker experimental binary’ that currently contains a new networking and plugin system, and Apache Mesos integration with Docker Swarm.
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.
At DockerCon 2015, Solomon Hykes announced that a broad coalition of vendors, users and industry leaders are coming together to form the Open Container Project (OCP) for the express purpose of defining common specifications around container format and runtime. The OCP will be run under the auspices of the Linux Foundation as a minimalist, non-profit, openly governed project.
A successful CNUT closed-door meeting, a Container Technology Club organized by InfoQ, was held in the Beijing Babbitt Internet-themed tea house on 16th June, 2015
At GlueCon 2015, Adrian Cockcroft presented a list of rules for monitoring microservice and container-based applications. In addition to these guidelines, Cockcroft also highlighted a series of challenges for monitoring cloud-native container-based systems, and introduced his ‘Spigo/simianviz’ microservice simulation and visualisation tool.
Last week, RedHat hosted a "Microservices Architecture Developer Day" in London, and presented a set of technologies and patterns that can be used to create microservice-based applications using open-source solutions like Kubernetes, Docker, Fabric8 and Maven. Read on for more details about the day, including links to the presentations and demo videos.
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.
