How to build a private IaaS cloud platform? - Main Post

I had the chance to give talks about evaluating the requirements for, and building private IaaS cloud platforms.

Often I was explained the following situation: A corporate manager went to OpenWorld, a local Oracle Day or a Virtualization Day, and has seen everywhere that cloud platforms are the future. As a good businessman, he wants to benefit from the new wave and wants you, the system administrator/datacenter engineer/platform architecht to build an Infrastructure as a Service platform to provide virtual environments for your internal or external customers. What do you do? Allow me to point out some of the requirements and considerations.

Clustering Basics and Challenges

For upcoming posts it seemed to be a good idea to dedicate some time for cluster basic concepts and theory. This post misses a lot of details that would explode the articlesize, should you have questions, do not hesitate to ask them in the comments. 

The goal here is to get some concepts straight. I can't promise to give you an overall complete definitions of cluster, cluster agent, quorum, voting, fencing, split brain condition, so the following is more of an explanation. 

Here we go.

Summary of the Solaris 11 webcast's livechat QnA session

This is a followup post to the previous summary on the "What's new with Solaris 11 since the launch" webcast. That webcast has had a chatroom for a live Questions and Answers session running. I went through the archive of those and compiled a list of some of the (IMHO) most relevant and most frequently asked questions, I'd like to share. This is the first part, covering the QnA of Session I and II of the webcast, in a followup post we can have a look of the rest of the sessions if required - let me know in the comments. Also, should you have questions, as usual, feel free to ask those there too. [Read More]

So, what makes ZFS so cool? (Part I: high level overview)

I have the privilege to do Solaris 11 tech-updates/demos at customers. It always amazes me how much they are amazed by ZFS. Don't get me wrong, ZFS is really cool. But it isn't exactly new technology, it's been around for a while now, the first implementations in 2003, included in Solaris 10 since S10 Update 2 in 2006. Everyone has heard about it being awesome, but every now and then I get the question for detauls: So tell me, what really makes ZFS so cool? 

Let me tell you about it.

Everyone is talking about Cloud these days. Everyone is explaining how the cloud will help you to bring your service up and running very fast, secure and with little effort.
