Will Cloud Computing level the playing field?

Lately, we hear about “cloud” everything. But the cloud is forming, it is available today. I admit, it is still in it’s infancy, but you need to be thinking about the impact it will have on business and IT. How do you plan to take advantage of this technology/service offering?

For many, I think cloud computing technologies and concepts will allow them greater agility and effectively eliminate the barrier of entry into many technology services. A startup can leverage the cloud to quickly deploy an enterprise class infrastructure, and the big players need to be preparing for this as well.

I discuss this in more detail in my article “Public cloud computing levels the playing field” on SerchServerVirtualization. Please take a minute to read the article, then come back here to leave any comments.

It’s 10pm, where is your capacity?

You can no longer simply set an alarm on capacity measurements and trust that to keep you clear of capacity problems, especially if you are looking at virtualization and/or cloud computing. Shared resources are a tremendous gain for efficiency, but can be a double-edged sword when it come to managing that shared capacity. It is well worth the extra effort, but you need to know how critical that extra effort is.

You can no longer just know where your capacity is, you have to know how it got there, where it is going, why it is going there, WHEN it is going there, what factors may speed up or slow down that growth rate…I think you get the point. The role of resource/capacity management has just stepped into the spotlight, and you need to adjust your policies and practices to recognize that.

Shiney new IT toys

All that glitters is not gold…sometimes it is simply a distraction. Sometimes, and I have been guilty of this, we let the desire to implement technology get in the way of meeting business needs. It can be very tempting, after evaluating an amazing new technology, to then begin looking for excuses opportunities to use it. Sometimes you find that true win-win scenario where that technology is the exact fit, and sometime you end up making it fit in the hopes that it will show increased value in the future.

Fred Nix hit this point very well with his post on 1/4 inch drill bits. Sometimes we simply need to step back and evaluate why we are looking at a new technology. If you are impressed with a presentation or excited after evaluating a new technology, then make note of that and add it to your toolbox of solutions. Then, when the right opportunity presents itself, reach into your toolbox and pull out the right solution for the problem in front of you.

Read more about this in my article “New IT Trends: Are they right for you?“, then come back here to leave any comments. As always, your thoughts and feedback are encouraged.

Opportunity Cost

When you are presented with two or more mutually exclusive options, you are going to have to pass up an opportunity. The key to making the right decision not only lies in knowing the value of both options, but in looking for a possible third option and assessing the value of that option as well. The value of the opportunities not taken are the “opportunity cost” of your decision.

A simple way to explain opportunity cost is to consider selling an item at cost. If I buy a widget for $10, and I sell it to you for $10, I have recovered my cost and lost no money…right? That is true in simple financial terms. However, consider that I could have easily sold the widget for $15, that decision had an opportunity cost of $5. I passed up an opportunity to make $5 by selling it to you at cost.

That concept changed the way I approach IT decisions, teaching me to always consider the business value and cost. No matter how good my design, the business may have other opportunities available that would yield a better return. My designs not only have to be good, they have to be valuable.

Another impact of learning this lesson…I no longer ask my friends who own businesses to sell me items at cost 😉

Too Big To Fail – VM Density and HA

Over the last few years, we have heard the term “too big to fail” thrown around in many conversations. Often, this has been used to describe large organizations whose influence within a particular market has elevated them to a point where their failure would have a devastating impact on theirs or related markets. In the United States, this term has been used to justify government intervention where the cost of failure would outweigh the cost of intervention. Putting aside those financial and political arguments, let’s focus on the concept of “too big to fail” in a virtual infrastructure.

As hardware vendors continue to make dramatic leaps in processing power, it becomes easy to build a server capable of ridiculous virtual machine densities. But you should be careful, all that glitters may not be gold.

Be Good On Purpose

You do a little online research, pick a mature technology that is well established, perform a quick install and everything just works. The sun is shining, deadlines are met, birds are singing and you are a hero. That scenario is not a stretch, it happens every day. Many tools have dedicated significant effort to making their installation “idiot proof”, but what happens next?

As your environment grows, cracks begin to emerge in the foundation of your new tool. They may start small, but they grow and spread. Where did these cracks come from, where will they appear next, what damage can they cause? At every step of the installation, you accepted the default settings and moved on. Each of those options were forks in the road and you took a direction, without knowing the options available and without knowing why. Now, you do not know where you are, how you got there or how to correct course.

Maybe you did everything right, but did you do it on purpose? If you do not know why your deployment was successful, if you did not develop and enact a careful plan to result in a solid environment…then you got lucky, at best. The initial results may look the same, but the long term results and the value provided will be miles apart.

Too often in IT, I meet people willing to simply get a task done and move on, literally leaving a mine field in their wake. It would be better to fail following a plan than to succeed without one. When you follow a plan, you can retrace your steps, correct course and move forward. When you have blind success, you create a false sense of security that can cripple an organization when things finally go “bump” in the middle of the night. Trust me…eventually, everything goes “bump”.

Be good, be bad, be deliberate or be careless, just do it on purpose.
