Google’s infrastructure has been the source inspiration for research papers, software projects, and entire companies. Google pioneered the idea that we care less about the individual machines we are running our applications on, and more about the applications themselves.

Containers are the abstraction we use to separate the concerns of the application from those of the underlying hardware. CoreOS is an operating system built with this paradigm shift in mind. In a data center, the main job of the operating system is to be a platform for containers to run smoothly on. Brandon Philips is the CTO of CoreOS and he joins the show to explain what CoreOS does differently to power the applications that get deployed on top of it.

Akka is a toolkit for building concurrent, distributed, message-driven applications on the JVM. Akka provides an implementation of the actor model of concurrency, which simplifies concurrency by adding a lighter weight abstraction than threads and thread pools.

The Linux kernel of many popular operating system distributions contains 200-500 million lines of code. The average user never touches many of the libraries that are contained in these operating system distributions. For example, if you spin up a virtual machine on a cloud service provider, the virtual machine will have a USB driver. This is wasted space, because you can’t even interact with the USB port on a virtual machine.

Unikernels are a way to rethink our usage of operating systems. A unikernel uses a stripped down operating system called a library operating system–it contains only the libraries you need for the applications you are running. Today’s guest Scott Weiss joins the show to talk about unikernels, and a project he is working on called UniK, a tool for compiling application sources into unikernels.

GraphQL was open sourced out of Facebook, and gave developers a way to unify their different data sources into a single endpoint. Although the promise of GraphQL is appealing, the process of setting up a GraphQL server that can communicate with each disparate data source can prove to be complex.

Clojure is a dynamically typed functional language that runs on the JVM. Today’s guest Alex Miller gives us an overview of Clojure’s core functionality. Alex is a developer of Cognitect, and a founder of the the Strange Loop conference.

We discuss the data structures, garbage collection, and concurrency support. How does Clojure compare to other JVM languages like Scala and Groovy? How does Clojure copy immutable data structures without copying all of the data? How does a Clojure program get evaluated and converted to Java bytecode? These questions, and many others are discussed in this episode.

Odd Networks is building a platform for anyone to launch their own over-the-top streaming video service. With Odd Networks, you can deploy your own video channel using a Roku, Amazon Fire TV, Apple TV, and other services.

Prometheus is an open-source monitoring tool built at SoundCloud. It can be used to produce detailed time-series data about a distributed architecture. Prometheus is based on the monitoring system inside Google’s infrastructure, called Borgmon.

Julius Volz is the creator of Prometheus, and he joins the show to explain why he built Prometheus and how it differs from previous monitoring tools. Prometheus is widely used to monitor Kubernetes clusters, just like Google uses Borgmon to monitor its Borg clusters.

github has grown to have 10 million users and 30 million repositories. Getting to this scale has required innovation in many places–github has significantly altered the code for git itself, and has built unique infrastructure and written low level code to architect for git repository management at scale.

Despite the need for cutting-edge technologies to support github, the development culture at github values tried and true technologies, and today’s guest Sam Lambert explains the value of maintaining a Rails monolith as the frontend of github, and the other battle-tested tools that github uses.

Open source software has become the rule for how software is written rather than the exception. OSCON is O’Reilly’s open source conference, where companies and individuals talk about where the open-source world is going.

Rachel Roumeliotis is the chair of OSCON, and she joins the show today to talk about the state of open source, and how the conference has developed since she started working at O’Reilly.

We are giving away a free ticket to O’Reilly’s Velocity 2016 conference in New York. If you want to be entered to win that ticket, send a tweet about your favorite SE Daily episode about dev ops or web performance, and tag software_daily, as well as #velocityconf.

The container management system Kubernetes was open sourced by Google with the intention of creating a cloud service based on the project. Today, the Kubernetes ecosystem is looking similar to the Android ecosystem, with different vendors providing different ways to use Kubernetes, from RedHat’s OpenShift to Google Container Engine.

Craig Mcluckie was a member of the team who originally devised Kubernetes, and he joins the show to talk about the origins of Kubernetes and where the project is headed, exploring both the technical architecture and Google’s business strategy around Kubernetes.
