Netflix has recently made available the source code of the Chaos Monkey 2.0. The latest iteration of the resilience tool is fully integrated with Spinnaker and event tracking systems, but the SSH support has been removed.
Continuous deployment results in a higher sense of responsibility and better quality of deployments, argues Paul de Raaij, technical pathfinder at Coolblue. Coding standards prevent your code base from becoming a mess, automated inspections are great for tedious and boring checks, and manual checks are great for checking if the logic or use of code actually makes sense.
Stefan Thies, DevOps Evangelist at Sematext, in a recent post discusses ten important container monitoring metrics and their implications on operating Docker containers, specifically when running many containers per host. Combined in a single correlated view these metrics provide a starting point for monitoring Docker-based environments.
Windows Management Instrumentation (WMI) is a primary source of data when monitoring Windows systems. Given that the performance counters available vary from machine to machine, a tool is needed to list all counters available. The WMI type provider is one possible option to explore WMI performance counters.
This post describes the applications of the shooting target in kanban board introduced by Tomas Rybing.
At the microXchg conference, held in Berlin, Adrian Cockcroft presented “Analyzing Response Time Distributions for Microservices”. Cockcroft demonstrated how the combination of his Spigo microservice architecture simulation tool and the online Guesstimate Monte Carlo method tool can be used to visualise and experimentally simulate request response times within a complicated microservice system.
Klaus Leopold gave a talk at the GOTO Berlin 2015 conference in which he elaborated why focusing on team-level performance often leads to local suboptimalization and doesn't increase agility across the team. InfoQ interviewed him about why installing agile frameworks does not help to increase agility, how kanban can be used to increase collaboration, and benefits that teams can get from kanban.
Kevin Goldsmith talked about how Spotify uses microservices to break down architectures and be innovative at the GOTO Berlin 2015 conference. He argues that Microservices are easier to test, deploy and monitor than monolithic applications. Spotify also aims to have as few as possible dependencies in their product, and microservices are very helpful for that.
People can tell stories and express themselves when trying to solve complex problems using Lego. Jens Hoffmann facilitated the session "Prototyping an Agile Culture with LEGO® SERIOUS PLAY®" at the GOTO Berlin 2015 conference.
At DockerCon EU 2015 Brian Christner presented an overview of ‘Docker Monitoring’ and shared best practices, a guide to the Docker stats API, and a comparison between three popular monitoring options: cAdvisor, ‘cAdvisor + InfluxDB + Grafana’, and Prometheus.
James Lyndsay did a workshop titled "a nest of tests" at the Agile Testing Days 2015. In this workshop he explored how you can design large collections of tiny tests and visualize their output to test systems, and showed how tools can help you to do it. InfoQ interviewed him about this testing approach.
Runscope, an API monitoring and testing vendor, announced the general availability of Live Traffic Alerts, a real time API performance monitoring solution for live production traffic for key API transactions. InfoQ used this opportunity to speak to Runscope about their vision and the value their platform brings to its consumers.
Obeya is a management approach that uses war rooms and visualization for managing projects. InfoQ did an interview with Malika Mir about why she decided to implement Obeya, how they are using Obeya to manage project portfolios, their experiences with Obeya and the benefits that they have got from it.
In theory the operations team determines what the thresholds for warnings and alerts should be. But in practice, the operations team often have no idea what these values should be. Using machine learning techniques such as adaptive thresholds, Splunk ITSI solves this problem.
This post talks about five innovative kanban boards.
