Home Lab v2.0

It was a sad day when I realized my macbook pro was more powerful than my home lab server. However, it was the fact that the RAID card on my home lab server could not perform on ESXi 5.x that finally put me in the market for some new gear. So the question is what did I get and why?

Standardizing ESXi Configurations

Maish over at Technodrone posted a great article yesterday titled: Host Profiles Should Become a Standard Feature. In the article he states:

Having your hosts configured exactly the same should be a standard feature. It is in VMware’s best interests. It means less support calls, less anguish from customers, better customer adoption there are more than enough reasons.

I absolutely agree! The problem is in order to achieve host standardization given how vSphere is currently architected you need to abstract the configuration out of the host and into vCenter Server. Today, that is where Host Profiles come into play. The problem with Host Profiles are two-fold:

Cloudy with the Chance of Computing – Part 2

In my last blog entry about cloud computing, I answered the question: what is cloud computing? To do this, I defined the term cloud and then laid out some fundamental characteristics of cloud computing. Now, I would like to give a more formal definition of cloud computing. In perusing multiple articles on the topic, it has become apparent to me that there is no globally accepted definition of the term. This is understandable given the fact that cloud computing is still an evolving paradigm. In addition, many definitions that are available lack core and fundamental characteristics of the term.

Cloudy with the Chance of Computing – Part 1

My good friend Luca sent me the following email a couple weeks back:

I thought you would find this Q&A in the newspaper entertaining. The Dallas Morning News just lost your company money:

Question: I’ve been listening to and reading a lot of tech news lately, trying to stay current, and there’s something that I’m having trouble understanding – cloud computing. What exactly does that term mean?

Answer: The cloud is a metaphor for ‘the Internet’. This started because in drawing flowcharts of various computer networks, the Internet was usually represented by a drawing of a cloud. Simply put, cloud computing means using the Internet to provide your programs and store your data. Instead of spending $300 on a new copy of Microsoft Office, you might find that Google’s online suite, Google Docs, will do just fine. With Google Docs, for example, you create your word processing or spreadsheet documents through Google’s Web site and you don’t have to install any software. It’s all stored ‘in the cloud.’ So ‘in the cloud’ has come to mean any online application or storage. Read the Wikipedia entry on cloud computing if you’d like to know more.

This got me thinking, what is cloud computing?
