VMworld 2014 Day 1 Keynote

This is a liveblog of the day 1 keynote at VMworld 2014 in San Francisco, CA. (Well, it’s a “semi-liveblog”; I’ll post this immediately after the keynote session wraps up.) As in previous years, the keynote is being held in the massive space in Moscone North, and this year—like previous years—it looks like there is quite a crowd gathered here this morning. I have the privilege of sitting with newly-minted VCDX-NVs and other VCDXes.

A Heat Template for Docker Containers

In this post, I’ll share a simple template for deploying Docker containers in an OpenStack environment using Heat. Given that Docker is targeted at application deployment, then I felt that using Heat was a more appropriate way of leveraging Docker in an OpenStack environment as opposed to treating Docker as a form of a hypervisor. Later in this post, I’ll compare this approach to using a more container-aware solution such as fleet.

CoreOS Continued: Fleet and Docker

This post is the third in a series of posts on CoreOS, this time focusing on the use of fleet and Docker to deploy containers across a cluster of systems. This post builds on my earlier introduction to CoreOS and the subsequent more in-depth look at etcd.

CoreOS Continued: etcd

In this post, I’m going to build on my earlier introduction to CoreOS by taking a slightly more detailed look at etcd. etcd is a distributed key-value store (more on that in a moment) and is one of the key technologies that I feel distinguishes CoreOS from other Linux distributions.

VMworld 2014 Prayer Time

I mentioned this on Twitter a few days ago, but wanted to go ahead and formalize some of the details. A blog reader/Twitter follower contacted me with the idea of getting together briefly at VMworld 2014 for some prayer time. I thought it was a great idea (thanks David!), so here are the details.

Deploying CoreOS on OpenStack Using Heat

In this post, I’m going to illustrate one way to deploy CoreOS on OpenStack using Heat. By no means is this intended to be seen as the only way to use Heat to deploy CoreOS, but rather as one way of using Heat to deploy CoreOS. I’m publishing this in the hopes that others will be able to use this as a building block for their own deployments.

Cloud-Hosted Cloud Management via Platform9

A new startup emerged from stealth today, a company called Platform9. Platform9 was launched by former VMware veterans with the goal of making it easy for companies to consume their existing infrastructure in an agile, cloud-like fashion. Platform9 seeks to accomplish this by offering a cloud management platform that is itself provided as a cloud-based service—hence the name of this post, “cloud-hosted cloud management.”

Running Arista vEOS on KVM

In this post, I’ll show you how I got Arista’s vEOS software running under KVM to create a virtualized Arista switch. There are a number of other articles that help provide instructions on how to do this, but none of those that I found included the use of libvirt and/or Open vSwitch (OVS).

Welcome to Technology Short Take #43, another episode in my irregularly-published series of articles, links, and thoughts from around the web, focusing on data center technologies like networking, virtualization, storage, and cloud computing. Here’s hoping you find something useful.
