I have spent a few days now playing with CoreOS and helping other members of HP's Advanced Technology Group get it running on their setups.
Today I thought I would write about the good and the bad about CoreOS so far.  Many components are in an alpha or beta state so things may change over the coming months.  Also as a disclaimer, views in this post are my own and not necessarily those of HP.
Installation
As stated in my blog post yesterday, I have been using CoreOS on my Macbook Pro using Vagrant and VirtualBox.  This made it extremely easy to setup the CoreOS cluster on my Mac.  I made a minor mistake to start with, and that is to not configure the unique URL required for Etcd correctly.  A mistake a colleague of mine also made on his first try so it likely to be a common one to make.

Tesora, previously called Parelastic, asked Percona to do a sysbench benchmark evaluation of its Database Virtualization Engine on specific architectures on Amazon EC2.

The focus of Tesora is to provide a scalable Database As A Service platform for OpenStack. The Database Virtualization Engine (DVE) plays a part in this as it aims at allowing databases to scale transparently across multiple MySQL shards.

DVE was open sourced last week. Downloads and …

Percona Live MySQL Conference & Expo - March 31st to April 4th

The Severalnines Team Will Be Onsite at Booth 418 - Come Say Hello!

If you’re still thinking about whether or not you should be attending the Percona Live MySQL Conference & Expo that starts on Monday 31st of March, here are 9 reasons (we are Severalnines after all) on why we’ll be there. May these help you positively in your decision making ;-)

1. The 2014 edition showcases the most promising program yet

Sounds like a cliché-reason to be listed here, but this year’s program is in fact quite diversified …

The Percona Live MySQL Conference and Expo 2014 runs April 1-4  at the Santa Clara Convention Center and Santa Clara Hyatt – but be sure to get there a day early for the inaugural Open Source Appreciation Day on March 31 – this event is free but because space is limited I suggest registering now to reserve your spot.

Interest is particularly high in OpenStack and its intersection with MySQL and Open Source Appreciation Day and the conference sessions and events reflect this. Last year, the Percona Live MySQL Conference included 4 talks with Trove (“Red Dwarf” at the time) as the …

I wrote previously about Percona Live Santa Clara 2014, and I want to bring to your attention something Percona has done that is very nice to open source communities: have an open source appreciation day.

Its before the conference (so on Monday), and you get a choice between the CentOS Dojo (great lineup there including many from Red Hat, Monty from MariaDB, and PeterZ from Percona) or the OpenStack Today (another great lineup …
