OpenStack Trove Day 2014 Recap: MySQL and DBaaS
+0 Vote Up -0Vote Down

OpenStack Trove Day

I just returned from a week in Cambridge, Massachusetts where I was attending the OpenStack Trove Day and the Trove mid-cycle meetup, both sponsored by the great folks at Tesora.

I am relatively new to the OpenStack and Trove arenas so this was a fantastic opportunity for me to learn more about the communities, the various components within OpenStack, and what part Trove plays. I found the entire event very worthwhile – I met a lot of key people in the community, learned more about Trove and its potential, and in general felt a great energy and

Getting my hands dirty on an OpenStack lab
+1 Vote Up -0Vote Down

Like you all may know, OpenStack is currently one of the coolest open source projects, so I was thrilled when I was asked to manage the deployment of an OpenStack lab for internal Percona use. Starting from basically zero, I created tasks in our Jira and assigned them to a pool of volunteer consultants. As usual in a service company, billing is the priority so I ended up losing the 2 senior guys but fortunately most of my time was with a customer that wasn’t very demanding and I could easily multitask with the project and fill the gap. So, here it goes…

To deploy the OpenStack lab we were given 8 similar servers in our Durham, N.C. offices. The specs

Paris OpenStack Summit Voting – Percona Submits 16 MySQL Talks

MySQL plays a critical role in OpenStack. It serves as the host database supporting most components such as Nova, Glance, and Keystone and is the most mature guest database in Trove. Many OpenStack operators use Percona open source software including the MySQL drop-in compatible Percona Server and Galera-based Percona XtraDB Cluster as well as tools such as Percona XtraBackup and

DBaaS, OpenStack and Trove 101: Introduction to the basics
+0 Vote Up -0Vote Down

We’ll be publishing a series of posts on OpenStack and Trove over the next few weeks, diving into their usage and purpose. For readers who are already familiar with these technologies, there should be no doubt as to why we are incredibly excited about them, but for those who aren’t, consider this a small introduction to the basics and concepts.

What is Database as a Service (DBaaS)?
In a nutshell, DBaaS – as it is frequently referred to – is a loose moniker to the concept of providing a managed cloud-based database environment accessible by users, applications or developers. Its aim is to provide a full-fledged database environment, while minimizing the administrative turmoil and pains of managing the surrounding infrastructure.

Real life example: Imagine you are working

CoreOS Review
+0 Vote Up -0Vote Down
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

Sysbench Benchmarking of Tesora’s Database Virtualization Engine

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.

Caveats with Eventlet
+0 Vote Up -0Vote Down
The Stackforge Libra project as with most Openstack based projects is written in Python.  As anyone who has used Python before probably knows, Python has something called a GIL (Global Interpreter Lock).  The GIL basically causes Python to only execute one thread at a time, context switching between the threads.  This means you can't really use threads for performance reasons in Python.

One solution to get a little more performance is to use Eventlet.  Eventlet is a library which uses what is called "Green Threads" and hacks on top of the networking libraries to give a mutli-threaded like feel to an application.  As part of this blogging series for HP's Advanced Technology Group I'll write about some of the things I found out

High-Availability Openstack on a shoestring budget: Deploying a Minimal 3-node Cluster
+0 Vote Up -0Vote Down
December 4, 2013 By Severalnines

As OpenStack deployments mature from evaluation/development to production environments supporting apps and services, high-availability becomes a key requirement. In a previous post, we showed you how to cluster the database backend - which is central to the operation of OpenStack. In that setup, you would have two controllers, while placing a 3-node Galera cluster on separate hosts. Now, it can be quite a leap to go from one VM with all services running on it, to a fully distributed setup with 5 VMs. The good news is that you can have a highly available setup starting with just 3 VMs.

Stackforge Libra - Balance your life!

I have been pretty quiet on the blogging front for quite a long time now.  The main reason for this is I have been working very hard on leading a small team which is developing a Stackforge project called 'Libra'.  As you can probably guess from the name, Libra is a Load Balancer as a Service system.  Many of you may not of heard of it but according to Stackalytics it was the 27th biggest project in terms of code contributed during Havana and 2nd biggest in HP (something I am especially proud of because it has been one of the smallest teams in HP Cloud).

It is based on the Atlas API specifications, creates software-based load balancers, is implemented in Python and sits on top of Nova instances rather than working under the

I’ll be in Hong Kong for the upcoming OpenStack Summit Nov 5-8. I’d be thrilled to talk database things with others present, especially around Trove DBaaS (DataBase as a Service) and high availability MySQL for OpenStack deployments.

I was last in Hong Kong in 2010 when I worked for Rackspace. The closest office to me was in Hong Kong so that’s where I did my HR onboarding training. I remember telling friends on the Sunday night before leaving for Hong Kong that I may be able to make dinner later in the week purely depending on if somebody got back to me on if I was going to Hong Kong that week. I was, and I went. I took some photos while there.

Public DNS resolve for VM instances hosted at OpenStack nova compute grizzly edition

Issue – the OpenStack instances hostnames are not resolved at the moment by their floating IPs.

Fast solution – use PowerDNS
Short story:
1. Boot an instance , assign it a floating IP, open tcp ports 22 8001 and udp port 53.
2. Install PowerDNS, the particular yum package is named pdns.
3. install the mysql backend for PowerDNS, its available as yum package as well.
4. Install MariaDB , set the proper configuration, the initialize it at the default location.
5. Set the pdns user, create the pdns database and create the tables needed.
6. Configure the pdns service to use the gmysql backend.
7. Create and user at the OpenStack MySQL able to connect from the floating IP subnet.
8. Grant that user select permissions on all nova.* tables.

On big technical meetings, or why the end of the UDS is a bad idea
+0 Vote Up -0Vote Down

Canonical has just announced that the Ubuntu Developer Summit will no longer be face to face and every six months. Instead it will be entirely online and virtual, using Google Hangouts. (Here is the announcement.)

On the surface, this seems like a good idea: It's cheaper monetarily, it appears to open things up to people who are unable to travel, and it makes it easier to make complete records.

However, I think it's a bad idea, for several interrelated reasons.

Some decision making needs face-time to happen. For whatever reasons, internet-only communication is not enough for a good enough "meeting of the minds" for sticky or subtle engineering and design decisionmaking.
