New Webinar: A DevOps Guide to Database Infrastructure Automation for eCommerce
+0 Vote Up -0Vote Down

December 17, 2014 By Severalnines

For an online shop, the website is the cash register. It has to be open for business 24 hours a day.

As the ops person on duty, when you get a call at 3am after your website went down, your priority number one is to restore the service asap. But why can we not have our application stack automatically recover, and not have the pager wake us at all? Why do we still stick to tedious manual processes, which take up time and resources, and hinder future growth?

Infrastructure automation isn’t easy, but it’s not rocket science either, says Riaan Nolan. Riaan has been in …

Building a MySQL Private Cloud: Step 1
+1 Vote Up -0Vote Down

Building clusters is usually a fun time. Here’s one of my setups at the Equinix LAX1 facility that is being used for VPN services, OpenVZ clustering, and general RADIUS and MySQL clustering integration. Once the clustering design is finalized, it’s still in flux state while I try out different setups, I’ll post some physical+logical architecture diagrams to show “How to Build a Fault Tolerant Infrastructure for Virtualized MySQL NDB Cluster + Python-based VPN systems.” Stay tuned for more.

MySQL 5.5.4 looks awesome.
+5 Vote Up -0Vote Down

Been at the MySQL conference the last few days, and I have to say, I’m really blown away by MySQL 5.5.4‘s improvements.  Last year I keynoted and I begged Oracle on stage to realize that MySQL and InnoDB under one roof represented opportunity.  It’s clear they heard the community – this is some serious progress, and right when we needed it.

Been asked a few times in the last few days about where my slides are from my MySQL keynote from *last* year.

Ooops.

Um, yeah.  Sorry about that.  Here’s a link to ‘The SmugMug Tale’ slides, and you can watch the video below:

Sorry for the extreme lag.  I suck.

Ian Bullard asserts that you should never use the RAND() function. The Ayn Rand Google Ad is pretty funny. The new Zend Server is coming out as a web stack. Although it can be easier to install a Xampp style … Continue reading →

On Why Auto-Scaling in the Cloud Rocks
+0 Vote Up -0Vote Down

In high school, I had a great programmable calculator. I’d program it to solve complicated math and science problems “automatically” for me. Most of my teachers got upset if they found out, but I’ll always remember one especially enlightened teacher who didn’t. He said something to the effect of “Hey, if you managed to write software to solve the equation, you must thoroughly understand the problem. Way to go!”.

George Reese wrote up a blog post over at O’Reilly the other day called On Why I Don’t Like Auto-Scaling in the Cloud. …

Sweet new Sun storage stuff on Monday, Nov 10th
+0 Vote Up -0Vote Down

FYI, Sun is announcing some sweet new storage stuff on Monday at 3:30pm PT.

I’m reviewing a few of the things they’re announcing, and hope to publish my thoughts here soon (one of them joins my production network tonight if all goes well). However, I’m at Disneyland with my kids (first trip!) from Monday through Thursday, so I don’t know (yet) when I’ll be able to write them up. Bear with me if it takes a few days.

But the gear is exciting, and the direction Sun is headed is even more exciting!

Network.com setup in Vegas, Thumper disk bay, green by Shawn Ferry

As I expected it would, the fact that I used ZFS compression on our MySQL volume in my little OpenSolaris experiment struck a chord in the comments. I chose gzip-9 for our first pass for a few reasons:

  1. I wanted to see what the “best case” compression ratio was for our dataset …

Success with OpenSolaris + ZFS + MySQL in production!
+0 Vote Up -0Vote Down

Pimp My Drive by Richard and Barb

There’s remarkably little information online about using MySQL on ZFS, successfully or not, so I did what any enterprising geek would do: Built a box, threw some data on it, and tossed it into production to see if it would sink or swim.

I’m a Linux geek, have been since 1993 ( …
