Force12.io have released a prototype ‘microscaling’ container demonstration running on the Apache Mesos cluster manager, which they claim starts and stops ‘priority 1’ and ‘priority 2’ containers more rapidly than traditional autoscaling approaches when given a simulated demand for the differing workloads. InfoQ discussed the goals and methodology of this approach with Force12.io’s Ross Fairbanks.
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.
Optimizing queries in Splunk’s Search Processing Language is similar to optimizing queries in SQL. The two core tenants are the same: Change the physics and reduce the amount of work done. Added to that are two precepts that apply to any distributed query.
A surprisingly common theme at the Splunk Conference is the architectural question, “Should I push, pull, or search in place?”
If you could handle all of the data you need to work with on one machine, then there is no reason to use big data techniques. So clustering is pretty much assumed for any installation larger than a basic proof of concept. In Splunk Enterprise, the most common type of cluster you’ll be dealing with is the Indexer Cluster.
When working with Hadoop, with or without Hunk, there are a number of ways you can accidentally kill performance. While some of the fixes require more hardware, sometimes the problems can be solved simply by changing the way you name your files.
This post talks about five innovative kanban boards.
Oracle shocked the Java world this week by announcing the dismissal of some of their top Java evangelists including Cameron Purdy and Simon Ritter.
The volatility in the market requires that organizations become able to adapt to changing demand as fast as possible while gaining the highest value. To implement agile managers need to team up to remove impediments in the organization says Ahmet Akdag. An agility transformation is about learning to try, fail and learn.
Java has introduced a new option that enable generation of mixed-mode flame graphs in JDK versions 8 and 9. InfoQ speaks to Netflix performance engineer Brendan Gregg about how this option gives application developers a clearer, combined system and JVM profile of their applications than was possible before.
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.
Professional services firm, which employs hundreds of thousands of workers in cities around the globe, has been quietly preparing for the “massive revolution” of getting rid of annual performance reviews and rankings, in its internal operations.
Go 1.5 has a complete tool chain written in Go, a quicker garbage collector and runs a goroutine on each available CPU.
RebelLabs published their Developer Productivity Report, the result of a survey started in March 2015, where they polled the Java development community on Java performance and performance testing methods. To see how these numbers line up with a real world experience, InfoQ spoke with Kirk Pepperdine, CTO at JClarity and well-known performance expert.
QASymphony has released qMap, a visual mapping solution for agile testers of cloud, mobile, big data and IoT apps. InfoQ did an interview with Kyle Cochran about why qMap was developed, how testers can use qMap to get insight into their testing results and manage testing and can use information from qMap improve the quality of their product, and how QMap can be deployed within agile and DevOps.
