Mesos, Yet Another Cloud OS? YARN stands for Yet Another Resource Negotiator. According to Hortonworks, it is "the architectural center of Hadoop". YARN is the stack layer that allows multiple processing engines, with varying workloads (streaming, SQL, batch, machine learning etc.) to run on top of the Hadoop file system, HDFS. Before YARN there was another resource negotiator, Mesos (Hence the "yet another" in YARN) Mesos was originally documented in a research paper, followed by an Apache project, and now commercialized as Mesosphere - who are building out an ecosystem around Mesos. Is Mesos yet another cloud OS? In fairness to Mesosphere, their marketing doesn't stray into the hyperbole of calling Mesos a Cloud OS (maybe a data center OS or a distributed systems OS). This makes sense because it would probably confuse people. However, they do talk about running yo... (more)

Keep CALMS and Release More By @TrevParsons | @DevOpsSummit [#DevOps]

How to Keep CALMS and Release More DevOps is fundamentally changing. It is no longer considered a fad by those working with the latest development tools.

The first step is to understand there is a big difference between data collection, and it's utilization. While it seems subtle, the difference is key, and utilization is where many make mistakes. Many confuse data collection and data uti... (more)

What Is JSON? By @TrevParsons | @DevOpsSummit [#DevOps]

Three Common Problems Solved With JSON One of the most common questions we get asked by customers is: “What’s the best way to log my data?” My answer is always: "log using JSON format wherever possible.” The next question we often get asked – (but not as much)… Yeah JSON, …Hmmm, what is JSON again? So JSON is: So JSON is: JavaScript Object Notation. But put simply, this is a way that data can be stored in a structured format, where each piece of data will usually have an identifier (known as a key) and a value (which can be in multiple formats). It also can have a nested structure... (more)

Log Analysis and Automated Orchestration | @DevOpsSummit [#DevOps]

Log Analysis Takes Automated Orchestration Further Log analysis is a simple and cool way to add oversight to your orchestration environments. While scripting your infrastructure is a powerful tool, using it alone is a quick-hit device. But wait, there is more! You don’t even have to create the scripts manually; there are tools out there that will scan your base environment, and make the scripts for you!
