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.
Amazon Web Services has recently introduced s2n, short for “signal to noise”, an open-source implementation of the TLS/SSL protocols that aims to be “simple, small, fast, and with security as a priority”.
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.
At the recent devopsdays Amsterdam 2015, Patrick Roelke contended that monitoring still has lots of issues. Roelke believes that data science can help by eliminating static thresholds and coalescing information from various data sources into a single metric. The talk included a quick overview of monitoring tools that leverage data science: Kale, Bosun and AnomalyDetection.
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.
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 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.
At QCon New York 2015, David Fullerton presented a deep-dive into the monolithic C# / MS SQL architecture that powers the Stack Overflow website, which handles over 4 billion requests per month. Fullerton argued that by focusing on performance, scalability was included ‘almost for free’; and that by minimising the number of external application services, the need to pay ‘SOA tax’ has been avoided.
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.
On June 12, 2015, the Jetty Project released version 9.3 of their flagship open source embedded application server, that day being the 20th anniversary of the project's beginning. Features of the release include HTTP/2 server (and client) support, Java 8 as a minimum, more Java NIO integration and an overhauled scheduler. They also removed SPDY networking support and fixed over 400 bugs.
