Everything is a Freaking DNS problem

Johan from Sizing Servers asked me if I could talk about my experiences on building (virtual) appliances at their Advanced Virtualization and Hybrid Cloud seminar . Off course I said yes ..

Slides are below ... Enjoy ..

A couple of weeks ago I wrote a post titled Dear IBM , I was too late .. I was on holliday last week when people started sending me text messages , such as .. "Game Over MySQL , Long live Ingress" or "No Eclipse for IBM", etc ...

I had ideas regarding the future of certain Sun products at IBM, now the game has changed .. it'ss how they will live on at Oracle :)

Similar Questions arise .. like indeed the future of MySQL, the future of Solaris etc ...

So regarding the future of MySQL , I don't worry at all, on the contrary ..
Oracle tried buying mysql before they already have Innodb .. they didn't kill it .. the MySQL offering is complementary to the Oracle offering, now they can tackle both markets.
And as already mentionned when writing my IBM letter ..

As for MySQL, Jeremey has some good insights.. the fact that different prominent MySQL folks have left Sun will only push the MySQL development model towards more openness.
And towards an even more Redder RedHat alike model, we already have the first CentOS alike rebuilds of MySQL , so a distribution model based on the same kernel with different feature sets or focus indeed might be the future.

Further there's what Monty Said ... hang on ... nobody mentions the fact that some core PostgreSQL people are on Sun's payroll how's that going to turn out ?

A more interresting discussion is the future of Solaris one.. Oracle has always had an eye for Solaris.. one day it is their most important platform, the other day they tell the world Linux is their prime development platform, it often was a matter of who was quoted.

As for Unbreakable Oracle did a smart thing.. they learned that they should build a full operating system themselves but , so why should they want to do that with Solaris ?

LinuxWorld has an article where oracle states their idea about Linux :
"
What we are working to do in the data center ... is to make Linux the default for the data center OS," Screven said in a speech at the Linux Foundation Collaboration Summit in San Francisco. "We want there to be no question"

They suggest a merger between Solaris and Linux is a potential alternative .. so what do we need to merge .. you'd say ZFS and DTrace ..,but do we really need ZFS ?
There has been a lot of writing already about BTRFS being the next big filesystem, maybe it could make ZFS obsolete, maybe it couldn't ..

I got no clue on what's going to happen with OO.org .. so I`m really going to keep an eye on that one ..

In my opinion the real loser in this deal .. HP .. they don't have a full stack to play with .. They have the hardware, some management and monitoring software soon to be obsolete but no Operating System, no Database, no Appserver, no Apps. So what's their next move going to be ?

Oh and if you really want to talk figures Larry Augustin has a good take on it ... the idea that Oracle could sell off some parts to Hitachi EMC etc, get MySQL and Sun for Free ... then quietly wait for RedHat .. to get Jboss who knows :)

PS. I already blogged about the impact of the acquistion on the Virtualization area over at Virtualization.com

Sometimes you have to step out of line to get a message through just write a viewpoint down in totally black, ignoring the white parts.

Earlier examples of these tricks were my rants on raid :)

The original work title of the Virtualization.com post actually was "VMWare, the New Microsoft, they gave us point and click and no clue for the user" But I selfmoderated that down to a more gentle title, not attacking a vendor :)

I think the message got through ...

Yes you get the,"he must be joking" feedback from some ,on one hand that accelerating the effect and on the other some people might think what an idiot , but that doesn't weigh up to the one person who realizes he should do integrity checks on OVF's too and other one that realizes he shouldn't randomly copy VM's back and forth while not checking where they come from ...

So for clarity sake I`m in favour of OVF as an open standard, assuming it is wiseley used :)

On a side note , One of the people commenting on Beaker's blog wondered if " he checks the signature of every piece of software he ever downloads" .. I let yum or apt-get do that for me..

It's not all black and white , Hope you enjoyed the show however :)

Next month I`ll be teaching a course on Virtualization at the KULAK.

Apart from my training there is also a Puppet training planned in Belgium.

As I assisted Luke in finding a location for the training I tought it might be a good idea to have a Puppet Users meetup while some people are already gathering in Leuven

Current plan is to meet up somewhere in Leuven on the evening of the 25th , more announcements later ..

So yesterday a 100+ crowd met in the Antwerp Zoo.
I heard different comments from that crowd... some of them liked the event, good networking, interresting topics , a broad overview, meeting new vendors active in the Cloud, others of them didn't .. it wasn't a real camp , just some vendors pitching, they didn't hear any new stuff , or we didn't touch the real stuff.

So different opinions from different expectations...

Anyhow for all those who could't read the slides :

Or here

I've updated the slidedeck of my Open Source Virtualization talk, with the 2009 edition as I gave it last week at the UKUUG Spring conference.

Talk is up, both on my page as on SlideShare

Tom also updated our set of Open Source Monitoring Tool Shootout slides .
They are also on SlideShare

The slides from the presentation I gave last friday at Lsec are now online, both at My Site and on Slideshare

I learned a lot last friday , I`ll be talking to some more people about the technical details , but be expecting some of my findings on Virtualization.com soon :)

When I tell people that the concept of copying VM's around as frequently done in the VMWare world is one of the most stupid ideas on this planet, I get the weirdest looks.

In my world it is, I want my infrastructure to be reproducible , I want to be able to throw any machine in my infrastructure out of the 10th floor of a building and be up and running again in no time. If I spread a bunch of VM copies around who knows what kind of life they start leading. Some will get upgrades, some won't ..
If I get an image from someone, how did he get there ? Nobody knows ..

To me Image Sprawl is more than not being able to to manage your Virtual Machines, it also matters for physical machines that are being deployed using a golden image.

Now rewind back about 4 something years.. back then I wrote a paper for LinuxKongress titled Automating Xen Virtual Machine Deployment which described a Hybrid way of Bootstrapping an infrastructure.
Quicly summarized, you use the benefits of images to quickly deploy a minimal image which
Luke today calls a Stem Cell then go on using centralized package management and a configuration management tool to keep them up to par. There are 2 things that changed in between,
we replaced CFEngine with Puppet , and the fact that today some people do care a bit more about the infrastructure side of the web, guess we have to thank Amazon and the Cloud Hype for that

But fundamentally .. not that much changed :)

This was not a CloudCamp !

Don't get me wrong, it was a great event and I met lots of interesting people , but it was not a *camp.
The idea was there to have an unconference after the formal sessions, but the formal sessions ran out and there was no time because of food and bar duties.

The event was a mixture of regular Belgian Campers, Virtualization geeks, Open Source folks , obviously there were a couple of "lost" americans , and the crowd from up North :)

The location was weird to say the least, what if the boat hat floated off on the river :)

It's obvious the world doesn't have a fixed definition for "Cloud Computing" yet , Tarry really made a safe bet by cut and pasting the definition from WikiPedia but the thing that really worried me was that when Raph asked if the audience could define Open Source they couldn't either.

Given the audience it's really hard to understand why they couldn't explain what Open Source is .. they should be able to. As the biggest chunk of Cloud Infrastructure is based on Open Source , the audience of a CloudCamp should be able to define Open Source, but then again there was quite a number of suits around that weren't expected to understand what it is all about :)

The fact is that a the cloud today still is a bit of undefined, different marketeers are grabbing the opportunity to rebrand their longtime existing product as fresh and hot cloud.

The interesting part of the Cloud to me is the mix of Virtualization, Scalability, Automation , Large Scale Deployment , playing the puppetmaster, and High Availability ..

It's stuff I have been doing for ages , it's the stuff this blog has been covering since the beginning ... but I don't plan on renaming my blog .. as afterall the whole cloud issue is just a Freaking DNS Problem

Pictures of the event are here
