I was having a discussion with a skeptical CIO the other day. His issue was that a private cloud isn’t real. Why? In contrast to the public cloud, which has unlimited capability on demand, a private cloud is limited by the size and capacity of the internal data center. While I understand this point I disagree and here is why. I don’t know of any data center that doesn’t have enough servers or capacity. In fact, if you talk to most IT managers they will quickly admit that they don’t lack physical resources. This is why there has been so much focus on server virtualization. With server virtualization, these organizations actually get rid of servers and make their IT organization more efficient.
Even when data centers are able to improve their efficiency, they still do not lack resources. What data centers lack is the organizational structure to enable provisioning of those resources in a proactive and efficient way. The converse is also true: data centers lack the ability to reclaim resources once they have been provisioned.
So, I maintain that the problem with the data center is not a lack of resources but rather the management and the automation of those resources. Imagine an organization leverages the existing physical resources in a data center by adding self-service provisioning and business process rules for allocating resources based on business need. This would mean that when developers start working on a project they are allocated the amount of resources they need – not what they want. More importantly, when the project is over, those resources are returned to the pool.
This, of course, does not work for every application and every workload in the data center. There are applications that are highly specialized and are not going to benefit from automation. However, there indeed can increasingly large aspects of computing that can be transformed in the private cloud environment based on truly tuning workloads and resources to make the private cloud as elastic as what we think of as a ever expanding public cloud.
I admit that I haven’t written a blog in more than three months — but I do have a good reason. I just finished writing my latest book — not a Dummies book this time. It will be my first business book based on almost three decades in the computer industry. Once I know the publication date I will tell you a lot more about it. But as I was finishing this book I was thinking about my last book, Cloud Computing for Dummies that was published almost two years ago. As this anniversary approaches I thought it was appropriate to take a look back at what has changed. I could probably go on for quite a while talking about how little information was available at that point and how few CIOs were willing to talk about or even consider cloud computing as a strategy. But that’s old news. I decided that it would be most interesting to focus on eight of the changes that I have seen in this fast-moving market over the past two years.
Change One: IT is now on board with cloud computing. Cloud Computing has moved from a reaction to sluggish IT departments to a business strategy involving both business and technology leaders. A few years ago, business leaders were reading about Amazon and Google in business magazines. They knew little about what was behind the hype. They focused on the fact that these early cloud pioneers seemed to be efficient at making cloud capability available on demand. No paperwork and no waiting for the procurement department to process an order. Two years ago IT leaders tried to pretend that cloud computing was passing fad that would disappear. Now I am finding that IT is treating cloud computing as a center piece of their future strategies — even if they are only testing the waters.
Change Two: enterprise computing vendors are all in with both private and public cloud offerings. Two years ago most traditional IT vendors did not pay too much attention to the cloud. Today, most hardware, software, and services vendors have jumped on the bandwagon. They all have cloud computing strategies. Most of these vendors are clearly focused on a private cloud strategy. However, many are beginning to offer specialized public cloud services with a focus on security and manageability. These vendors are melding all types of cloud services — public, private, and hybrid into interesting and sometimes compelling offerings.
Change Three: Service Orientation will make cloud computing successful. Service Orientation was hot two years ago. The huge hype behind cloud computing led many pundits to proclaim that Service Oriented Architectures was dead and gone. In fact, cloud vendors that are succeeding are those that are building true business services without dependencies that can migrate between public, private and hybrid clouds have a competitive advantage.
Change Four: System Vendors are banking on integration. Does a cloud really need hardware? The dialog only two years ago surrounded the contention that clouds meant no hardware would be necessary. What a difference a few years can make. The emphasis coming primarily from the major systems vendors is that hardware indeed matters. These vendors are integrating cloud infrastructure services with their hardware.
Change Five: Cloud Security takes center stage. Yes, cloud security was a huge topic two years ago but the dialog is beginning to change. There are three conversations that I am hearing. First, cloud security is a huge issue that is holding back widespread adoption. Second, there are well designed software and hardware offerings that can make cloud computing safe. Third, public clouds are just as secure as a an internal data center because these vendors have more security experts than any traditional data center. In addition, a large number of venture backed cloud security companies are entering the market with new and quite compelling value propositions.
Change Six: Cloud Service Level Management is a primary customer concern. Two years ago no one our team interviewed for Cloud Computing for Dummies connected service level management with cloud computing. Now that customers are seriously planning for wide spread adoption of cloud computing they are seriously examining their required level of service for cloud computing. IT managers are reading the service level agreements from public cloud vendors and Software as a Service vendors carefully. They are looking beyond the service level for a single service and beginning to think about the overall service level across their own data centers as well as the other cloud services they intend to use.
Change Seven: IT cares most about service automation. No, automation in the data center is not new; it has been an important consideration for years. However, what is new is that IT management is looking at the cloud not just to avoid the costs of purchasing hardware. They are automation of both routine functions as well as business processes as the primary benefit of cloud computing. In the long run, IT management intends to focus on automation and reduce hardware to interchanagable commodities.
Change Eight: Cloud computing moves to the front office. Two years ago IT and business leaders saw cloud computing as a way to improve back office efficiency. This is beginning to change. With the flexibility of cloud computing, management is now looking at the potential for to quickly innovate business processes that touch partners and customers.
