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.
Oracle is considering including JEP 248, making G1 the default garbage collector on server configurations, into the list of JEPs targeting Java 9. The decision has triggered some debate among the Java community, with many arguing that the CMS collector could have been more suitable.
At QCon New York 2015, Nori Heikkinen shared stories of failure and lessons learnt during her time working as a site reliability engineer (SRE) at Google and HealthCare.gov. The discussion of managing large-scale outages included recommendations for preparation, response, analysis and prevention.
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.
The Ember.js team has released the final iteration of the 1.x series, as well as their first 2.0 beta. The 1.13 release brings with it the Glimmer rendering engine, marking the third overhaul of Ember's 1.x rendering layer, and "dramatically improving re-render performance in many common scenarios," where previous iterations relied "on granular observation for efficiency."
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.
Facebook has made changes to their Graph API which Microsoft says has forced it to drop Facebook support from several Microsoft applications. This means popular apps like Windows Photos and OneDrive will no longer exchange data with Facebook.
Apache Parquet, the open-source columnar storage format for Hadoop, recently graduated from the Apache Software Foundation Incubator and became a top-level project.
