I have been working recently with Matt Yonkovit to get Waffle Grid cloud enabled with Amazon Web Services (AWS).

An initial version of Waffle Grid Cream - Version 0.5 release is now available.

We have elected to create one AMI for now, that is ready to be configured as either a MySQL Server, a memcached server, or as in the following example both. For this first version, we have also not configured MySQL or memcache, but rather provide a virgin Waffle Grid ready server for developers to experiment and benchmark with.

Future releases will include custom AMI’s and the automated ability to register new memcached servers with the Waffle Grid enabled MySQL server.

Instance Creation

We assume you have created an …

In a prior blog post , I explained how the "open source + paid support " business model only works for software products that address extremely large markets. However, even those large market products rely upon a rich collection of niche market products that combine to deliver solutions.

As the book Crossing the Chasm explains, every technology product must make the move from its early adopter or hobbyist roots to a mainstream application. The hobbyists are willing to accept tinkering with the product to make it work, but the much larger mainstream market wants to buy proven solutions .

As John Donne once said, "no man is an island." Similarly, no software application is an island; each one relies on an orchestra of tools, applications and services necessary to …

I discovered while compiling Wafflegrid today that by default, the Ubuntu binaries for memcached are not-multithreaded.

Following the installation of memcached from apt-get and libmemcached I ran memslap for:

$ memslap -s localhost
    Threads connecting to servers 1
    Took 1.633 seconds to load data

$ memstat -s localhost

We know that the open source + paid support business model works for software products that have extremely large numbers of users, but does it scale to products with medium or small numbers of users?

Software is often described as a stack (see the simplified version below).

Vertical Applications [Installed base = small]
————————–
Middleware (e.g. Database) [Installed base of MySQL = 12 Million]
————————–
Operating System [Installed base of Windows = 1Billion+]

Companies in the operating system layer typically have large numbers of users with a small license fee per user. This dynamic makes it relatively painless for a company to forgo a small license fee in exchange for a larger userbase, and then make money on support. For example, an open source company might forgo the $100 license fee, but charge $15 a seat for support. With large numbers of users, the …

Seem’s the year Sun had for improving MySQL, and with an entire new 5.4 branch the development team could not fix the autoconf and compile dependencies that has been in MySQL for all the years I’ve been compiling MySQL. Drizzle has got it right, thanks to the great work of Monty Taylor.

I’m working on the Wafflegrid AWS EC2 AMI’s for Matt Yonkovit and while compiling 5.1 was straight forward under Ubuntu 8.10 Intrepid, compiling 5.4 was more complicated.

For MySQL 5.1 I needed only to do the following:

apt-get install -y build-essential
apt-get install libncurses5-dev
./configure
make
make install

For MySQL 5.4, I …

For the fourth time in a row, I will be speaking at FrOSCon, one of the most charming open source events in Europe.
Hosted in the bright environment of the Department of Computer Science of the University of Applied Sciences Bonn-Rhein-Sieg, this event will get you hooked from the beginning. The organization is done by volunteers, who have always done an amazing job, with even better results than more expensive and famous conferences.
This year, there will be some more action than ever before. In addition to the main event, the organizers have given away a few developers rooms, to let some projects build their own event within the main one. There will be a Java subconference, and, closer to my interests, the European edition of the OpenSQLCamp 2009, which applies to all open …

For any production MySQL Database system, running RAID is a given these days. Do you know what RAID your database is? Are you sure?. Ask for quantifiable reproducible output from your systems provider or your System Administrator.

As a consultant I don’t always know the specific tools for the clients deployed H/W, but I ask the question. On more the one occasion the actual result differed from the clients’ perspective or what they were told, and twice I’ve discovered that clients when asked if their RAID was running in a degraded mode, it actually was and they didn’t know.

You can read about various benchmarks at MySQL blogs such as BigDBAHead and MySQL Performance Blog however getting first hand experience of your actually RAID …

OSCON moves this year from Portland to San Jose.

As one the community panel for Drizzle: Status, Principles, and Ecosystem I also have a speaker discount which you can combine with O’Reilly having also extended early bird registration until June 23.

Be sure to add the os09fos code for an additional 20% off, and be sure to shout me a drink there.

"An ecosystem is a unit of interdependent organisms which share the same habitat." - Definition: Ecosystem on Wikipedia .

Software comprises a symbiotic ecosystem that functions in much the same way as ecosystems found in nature. The various elements interact with one another, thereby providing a complete solution to users. ISVs and SaaS companies are part of the ecosystem of open source software (OSS), yet some of these companies are referred to as vampires, leeches, parasites and freeloaders because they don’t give back code to the community software.

Pardon my quick digression, but parasites are valuable members of any ecosystem. They do the dirty work of cleaning the ecosystem and turning waste into valuable food and fertilizer for the ecosystem. Consider, for example how your neighborhood …
