The Five Why’s of Cloud

53

John Willis / 

 

Editors note: This is the first post by our newest dev2ops.org contributor, John Willis.

 

 In my “cloudy” travels from Cannonical, to Opscode, to DTO Solutions, I often ask a seemingly simple question to the companies I meet – “Why do you want to use the cloud?” – and I get an array of amazingly unsatisfying answers.

Some people cite the classic 8-weeks-to-8-minute provisioning use case. Some people regurgitate the analyst answer of “for the ROI of (insert magic number here)” . Of course there is always the CAPex vs OPex answer. Now I am no financial type, but I’ve been around enough to know that in many types of businesses, OPex is more of a dirty word to the CFO than is CAPex.

Every once in a while I get a more informed answer like “I want to go to the cloud for agility”. But the usual lack of depth behind the answer proves to be just as unsatisfying.

 

The 5 Whys Epiphany

The other day I was having a conversation with my good friend Michael Cote and it hit me as to why I never get the depth of answer that I am am looking for. I have not been asking the right question(s).

Many of of us in our industry have learned and adapted many techniques and methodologies from Toyota’s lean manufacturing models. One of my favorites is the applying the “Five Whys” technique to determine a root cause of a problem. Therefore, I started applying the 5W’s during my informal surveys.

Here is an example of one of those conversations:

Question 1 – Why do you want the Cloud?

Answer: To decrease provisioning time.

Question 2 – Why?

Answer: So we can get servers provisioned in 8 minutes instead of 8 weeks.

Question 3 – Why?

Answer: So developers can get resources quicker to get there job done faster.

Question 4 – Why?

Answer: So they can get features out to customers faster.

Question 5 – Why?

Answer: So we make more money faster.

Aha, so that is why they wanted their cloud, to make more money and make it faster. At this point if I had more time I would start another line of questions (unfortunately I usually don’t) that begins with “Will the cloud do that for you?”.

Any of you who have been working with the cloud in a business for more than a year already know the answer to that question – Not out of the box it won’t. But dispelling the myth that Cloud alone solves all problems is not my point here.

My point is that the real question/answer I should have gotten to my initial “Why Cloud” question is that last question/answer after 5W’s. The real answer regarding “Why Cloud” should not focus on technical feature, it should be be based on specific business goals. Ask the 5W’s until those true goals are clear to everyone. Don’t doubt the power of “Why?”.

 

Begin With the End in Mind

They now teach to kids in elementary schools the idea of beginning with the end in mind. Its a lesson we can all learn from.

I like to use my cell phones in Russia analogy. When Eastern Europe opened up to capitalism, they didn’t go out and order land line phones all over the place. They knew from recent history that it was much easier to create new phone networks via cell phones. The began with the end in mind.

All too often, smart people lose site of this simple idea when it comes to the cloud. Getting a cloud is not the goal. The goal is to achieve a specific business objective (i.e., the root cause of why you want a cloud). Therefore if your real goal is “We want to make more money faster” then let’s map out the full path to get there.

I often describe the cloud as a big fence that comes just up to everyones eyebrows. It looks really cool but you can’t quite see what’s over the fence. I try to urge people to use a step ladder to look over the fence and see the longer journey. Most people will see that whats beyond the fence is not the end of the journey, but just the beginning.

Depending on what your business goal is, the end state which probably will include a cloud. But in almost every case, the end state will require far more than just a cloud.

 

In Cloud We Trust

I often hear in my travels the remark that “I thought the cloud did that”. It amazes me that an organization will first implement a cloud and then start asking questions like “where is the autoscaling part” or “where are the automated load balancers” or “where is the push button application deployment”. I call this the being blinded by the cloud pixie dust.

When the pixie dusts settles and they examine what their cloud really delivers, typically they will find that they are still missing what my good friend Damon Edwards calls the “abilities”. Around you cloud you are still going to need to create a strong operational infrastructure that delivers scalability, manageability, availability, reliability, flexibility, and – last but not least – agility.

In my forever quest to find the perfect cloud, I have yet to find one that comes with one big red “Abilities Button”. Sure the cloud will help with some of these — and some clouds provide more than others — but the cloud is just one tool that you will need.

Just like before the cloud, successful cloud-based operations include a hand full off glue technologies and a whole lot of additional sweat equity.

When analyzing your requirements, don’t let you thinking stop at the word “cloud”. Focus on what that actually means. Focus on ideas like:

  • Utility based infrastructure
  • Self-service resource allocation
  • Self-managing infrastructure
  • Software development life cycle support
  • Behavior driven availability

The cloud is just one part of the equation. Clouds are useful tools, but not the magic bullet. My suggestion, therefore, is to always apply the Five Why’s to make sure you know where you are going.

  1. what happens after cloud?

    • MikeC says:

      I don’t think there will be something after cloud when it comes to storage. I believe that public clouds will grow even more and sooner or later all companies will use this technology because the costs are getting smaller, but cloud technology gets safer.

    John,
    Fantastic post. I really appreciated it. I mentor some high school guys and have always made it a practice to never stop at surface level answers. I ask several why questions and it frustrates them to no end. But eventually there is a breakthrough and they understand more about themselves and their beliefs than if I had just stopped probing.

    This is no different with business and technology. Too often business and IT leadership don't ask Why enough and projects are spun up for incomplete reasons…often causing several projects to fail or not deliver on business value. We should all ask Why more and not settle for the first answer.

  3. Because of cloud-based computing, there will come a day where all platforms will offer convenience to each other, which in turn will bring forth great user-experience and massive financial turnout to IT companies. However, I predict we will encounter a massive bump ahead, specifically requirements related to security, Infrastructure as a Service (Iaas), and Software as a Service (SaaS). That's why I don't TOTALLY trust the cloud system at present.

    As most companies (large corporations, public and private organizations, and even SMEs) are now migrating to cloud, we begin to understand its functions and benefits. Nevertheless, I recommend a "wait and see" attitude towards this development.

    Great 5W's that every body need's to be answered!!!
    I would like to push this blog after 5W's, that is the benefits of using cloud computing in your business environment. That are as follows:
    * Availability of large computer infrastructure according to the business needs.
    * You have to pay according to a single uses or you can say pay per use.
    * Use it whenever you need it and pay only for that period of time and nothing else.
    * You have to rent cloud computing environment instead of buying it.

    These benefits of cloud computing is not going to stop in near future and famous provider will introduce you soon with brand new functionality and services to cut cost and gain more.

  5. Rajendra Vijay says:

    Some of the reasons why there are instances of customers going for Cloud without proper due diligence are

    1. Proponents of Cloud have been strongly supported by a strong marketing of Cloud Computing, so much so that if you do not have cloud, CIOs feel that they are missing out on something important.

    2. The hype and the pervasive media coverage has made higher management also aware of the Cloud phenomenon. This makes the job of CIO easy when he is trying to get the funds for a Cloud based initiative.

    3. Competition among the clients also benefit the cutting edge technologies like Cloud. They are either motivated by their competitor who has just gone Cloud or they simply do not want to be left behind and are not averse of being the first to try.

    4. Of course, cloud offers some genuine promises sought by most IT professionals.
