JVM monitoring vendor Plumbr has added slow query detection to its flagship product. With this addition, Plumbr now detects four types of problems: Memory Leaks, Garbage Collection Inefficiencies, Locked Threads and Expensive JDBC Operations.
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.
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.
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.
Apache Parquet, the open-source columnar storage format for Hadoop, recently graduated from the Apache Software Foundation Incubator and became a top-level project. Initially created by Cloudera and Twitter in 2012 to speed up analytical processing, Parquet is now openly available for Apache Spark, Apache Hive, Apache Pig, Impala, native MapReduce, and other key components of the Hadoop ecosystem.
GitHub has recently started revoking SSH keys that were deemed to be compromised or otherwise insecure. Systems engineer Ben Cartwright-Cox was the author of the research that uncovered the issues. InfoQ has spoken with him.
Apple has announced at WWDC 2015 that they will open-source Swift 2.0 under a permissive open-source license, the object-oriented/functional language released at last year's WWDC, and the standard libraries and compilers will run on iOS, OSX and Linux. Furthermore Apple has simplified the developer programs, allowing developers to build iOS, OSX and watchOS applications with the same membership.
Astrid Atkinson, director at Google, drew on their experiences over the last decade to present some rules and advice on engineering for the long term. The Velocity Conference 2015 attendees at Santa Clara learned that it's crucial to imagine that you're going to be wildly successful, that complexity mustn't be eliminated but managed and that the focus should be on scaling systems not teams.
Google have created a Kubernetes-based open source reference implementation that automates the building of custom Google Compute Engine VM images with Jenkins and Packer. The primary goal of this work is to demonstrate how to add image creation into a build pipeline for continuous delivery, and produce artifacts that may provide increased reliability and reduced speed of VM initialisation.
Capgemini are currently working on Apollo, an open source application platform built on top of the Apache Mesos cluster manager and Docker, which is designed to power next generation web services, microservices and big data platforms running at scale.
The third time may be the charm as Microsoft has announced intentions to produce native SSH client and server tools for the Windows platform. Using OpenSSH as a starting point, Microsoft says their goals for the new toolset includes easier system management of both Windows and Linux systems.
New Relic has released a set of new features to its Software Analytics Platform. Service Maps is a real time visual map focused on services. Together with a tool for Docker monitoring, a database dashboard for NoSQL databases and an unified alerts platform, the company wants to reduce complexity in modern software architecture.
