InfoQ interviewed Erik Doernenburg and Philipp Garbe from AutoScout24 about what made them decide to switch to the cloud and which benefits they expected, and how they manage computing resources using the cloud. InfoQ also asked them to give some examples showing how the cloud helps to deploy DevOps and to explain why teams are interested in working in an agile way and are eager to try new things.
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.
Earlier this month, Alex Miller, one of the main developers behind the Clojure Community, announced the latest version of Clojure. The flagship new features of Clojure 1.8 are Direct Linking, String Functions and Socket Servers, although it also includes a few minor enhancements and more than thirty bug fixes.
Hazelcast has released version 3.6 of their flagship in-memory grid and caching software, featuring numerous performance improvements and new cloud management and container deployment options.
For a long time now developers have been asking why Visual Studio hasn’t made to switch to 64-bit. Rather than effort or opportunity cost, the primary reason is performance. Rico Mariani of Microsoft explains.
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.
An interview with Nicole Forsgren about why organizations are starting to embrace DevOps methods, how being able to deploy fast can also increase IT stability, what to focus upon when changing the organizational culture to improve performance, how lean management can help to increase the performance, and asked her for advice when organizations want to apply DevOps to increase their performance.
Selena Delesie gave a keynote at the Agile Testing Days 2015 about leadership principles that she sees in successful agile companies. InfoQ interviewed her about how leadership principles from Sir Richard Branson are related to the foundations of agile and asked her which principles are giving companies a competitive edge and how companies can deploy agile to become more competitive.
A new Strict language extension to Haskell aims to make it easier to use Haskell for code that is meant to be mostly strict, i.e., evaluated in a non-lazy manner. The feature was recently merged into GHC’s git HEAD and will be included in GHC’s next release.
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.
Jelastic, a PaaS and container based IaaS provider, released Joker (Jelastic + Docker) 4.0 with advanced Docker features including horizontal scaling for containers, support for stateful containers with live migration and Docker volumes. The company has made improvements to Docker’s core technology to achieve the features in the Joker release.
Measuring the performance of single page applications (SPAs) presents some unique challenges. Philip Tellis, author of the boomerang library and Chief Architect at SOASTA, and Nicholas Jansma, senior engineer at SOASTA, deep-dived into the subject at the Velocity conference in Amsterdam, providing context and specific advice on how to measure performance for that kind of web applications.
