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.
Plumbr has launched a new Application Performance Management product in their performance monitoring toolkit, that automatically reports on which technical errors are the root cause for performance incidents that impact the end user, linking those to source code.
DigitalOcean recently introduced floating IPs that can be manually reassigned to any Droplet – what DigitalOcean calls a virtual machine – within a data center. While neither novel nor a standalone high-availability solution, this service fills a gap for the fast-growing cloud provider.
Amazon Web Services have released a series of updates for the Amazon EC2 Container Service (ECS) that include an ECS command line interface, Docker Compose support, task definitions that allow additional Docker configuration options, and an ECS scheduler update that adds support for availability zone awareness.
Runscope, an API monitoring and testing vendor, announced the general availability of Live Traffic Alerts, a real time API performance monitoring solution for live production traffic for key API transactions. InfoQ used this opportunity to speak to Runscope about their vision and the value their platform brings to its consumers.
Google has open sourced the specification for a restricted HTML that is meant to improve the mobile experience on the web.
Obeya is a management approach that uses war rooms and visualization for managing projects. InfoQ did an interview with Malika Mir about why she decided to implement Obeya, how they are using Obeya to manage project portfolios, their experiences with Obeya and the benefits that they have got from it.
Vishal Sikka, CEO of Infosys announced that Infosys has stopped using the bell curve phenomenon which is used to evaluate its 176,000 employees' performance.
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.
