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.
Fred George talked about the Challenges in Implementing MicroServices and The Secret Assumption of Agile at the GOTO Amsterdam 2015 conference. InfoQ interviewed him about how make microservices as small as possible, challenges when implementing microservices and how to deal with them, why programming style matters, and what developers can do to develop their code writing skills.
To make microservices awesome Domain-Driven Design (DDD) is needed, the same mistakes made 5-10 years ago and solved by DDD are made again in the context of microservices, David Dawson claimed in his presentation at this year’s DDD Exchange conference in London.
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.
An interview with Rob Howe, host of the MDSE session at the software engineering conference and CEO of Verum, about the state of practice and recent developments in model driven software engineering, the usage of this technology, whether he considers model driven software engineering to be a proven mature technology, and what the future will bring us in model driven software engineering.
When developing large complex systems and dealing with legacy code, organizations need to have systems in place to support integration and delivery. Modularization can help when agile is scaled with multiple teams that are working in parallel. It's not the framework or method that will do the job, but how your people will make it work to solve your problems says Hans Dekkers.
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.
Creating documentation is boring, it's often obsolete and misleading but with a new mindset both your documentation and code can improve, Cyrille Martraire explained in a presentation showing how to create living documentation when working with Domain-Driven Design (DDD) at this year’s DDD Exchange conference in London.
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.
There is tremendous value in microservices, probably giving us the best environment we have ever had for doing Domain-Driven Design (DDD), Eric Evans stated in his keynote at this year’s DDD Exchange conference in London. Iteration is the most important key to good design and microservices is the second attempt, after SOA, to get things right.
At QCon New York 2015, Kolton Andrus discussed Netflix’s Failure Injection Testing (FIT) platform, which allows the injection and monitoring of arbitrary failure scenarios to a targeted group of customers using the Netflix production web services. FIT allows Netflix to maintain an ‘antifragile’ programming culture, which results in the creation of systems that are resilient to failure.
Michael Bryzek, co-founder and ex-CTO at Gilt, discussed at QCon New York how ‘dependency hell’ could impact the delivery and maintenance of microservice platforms. Bryzek suggested that dependency hell may be mitigated by making API design ‘first class’, ensuring backward and forward compatibility, providing accurate documentation, and automatically generating client libraries.
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.
Owen Garrett, heads of products at Nginx, Inc., has described on Nginx’s blog which design decisions allow NGINX to provide top-in-class performance and scalability.
