Continuous Deployment at Coolblue
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.
Monitoring Metrics for Docker Containers
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.
Exploring Performance Counters with F# WMI Type Provider
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.
Tomas Rybing Introduces the Shooting Target - Value Kanban Board
This post describes the applications of the shooting target in kanban board introduced by Tomas Rybing.
Adrian Cockcroft on Analyzing Response Time Distributions for Microservices
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.
Don't Optimize Team-level Performance
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.
Microservices at Spotify
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.
Prototyping Mental Models with Lego Serious Play for Agile
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.
Docker Monitoring: Best Practices, and a Comparison of the cAdvisor and Prometheus Monitoring Tools
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.
Testing Systems with a Nest of Tests
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.
Interview with Runscope on API Testing and Monitoring
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.
Managing Project Portfolios with Obeya Rooms
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.
Splunk ITSI: Adaptive Thresholds and Anomaly Detection
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.
Various Types of Kanban Boards
This post talks about five innovative kanban boards.
Driving Transformational Behavior with Core Work Systems
Mike Orzen will talk about using core work systems to drive transformational behavior at the Lean IT Summit 2015. An interview on the benefits that organizations aim for with lean IT, why adopting and reinforcing new behaviors is essential to create sustained change, core work systems and work processes for IT organizations, and common missteps in lean IT transformations and how to prevent them.
