Technology leaders are moving towards Continuous Delivery and Agile to accelerate business innovation.This post talks about the importance of cultural shift in successful Continuous Delivery implementation in the organizations.
At the inaugural HashiConf conference, held in Portland, USA, HashiCorp announced the release of a new distributed scheduler platform named ‘Nomad’ that is capable of scheduling containers, VMs and standalone applications; and a new application delivery tool named ‘Otto’ that builds upon the existing Vagrant tool by enabling the management of remote application deployments.
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.
Based on their experience with arbitrarily shutting down servers or simulating the shutdown of an entire data center in production, Netflix has proposed a number of principles of chaos engineering.
An agile workplace is one that is constantly changing, adjusting and responding to organizational needs. How to create an Agile workplace and what are the benefits.
ARIN, the resource registry that hands out allocations for IPv4 addresses, has announced that it has no more IPv4 addresses to give out. Although this doesn't mean no more IPv4 addresses will be allocated, it has brought to an end the question of when such addresses will run out. Meanwhile, IPv6 usage continues to climb with the release of iOS 9.
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.
The DBA’s primary job is to ensure that the business’s information is always available, with performance coming in at close second. We’ve already talked about optimizing distributed queries in Splunk and map-reduce queries in Hunk. In this report we expand upon that with more information that a DBA needs to know about Splunk databases.
Puppet Labs’ latest version of Puppet Enterprise - version 2015.2 - includes new features like node graph visualization, inventory filtering, and a VMware vSphere module. It provides users with major enhancements of the Puppet Language and an updated web UI. InfoQ spoke with Michael Olson, Senior Product Marketing Manager at Puppet Labs .
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.
Splunk is jumping into the service-monitoring sector with a new visualization called IT Service Intelligence.
Splunk opened their big data conference with an emphasis on “making machine data accessible, usable, and valuable to everyone”. This is a shift from their original focus: indexing arbitrary big data sources. Reasonably happy with their ability to process data, they want to ensure that developers, IT staff, and normal people have a way to actually use all of the data their company is collecting.
