The Gartner Hype cycle research shows Cloud Computing as being on the peak of expectations… the very top of the hype bubble roller coaster.
Vendors are looking for something to sell, and the consolidation of the data center, reducing operational cost and economy of scale are as convenient of an excuse as anything. There are some fundamental technologies as well that will make a big difference such as Virtualization.
Is computing becoming a utility?
When someone refers to cloud, the etymology of the term should be examined. This term comes from the days of network diagramming, and a cloud was an abstraction for the network. Basically whenever someone didnt feel like drawing all of the network entities, they would just draw a puffy white cloud. In essence the puffy white cloud is shorthand for “don’t worry your pretty little head about this stuff”.
In doing so, one hands over both control and visibility to a third party.
If your cloud provider fails, then you fail. Unless of course your cloud provides non-essential services. Don’t count on it. Large scale failures such as Gmail recently point out some of the flaws in “don’t worry your pretty little head”. You better start worrying your pretty head. Failures aren’t the only problem implicit in the cloud, the lack of transparency can lead to privacy failure. No SLA can ensure privacy, just ask the customers of UBS Bank in Switzerland.
So are there things that a business should not have to worry our heads about? (whether they are pretty or ugly or little or big)
Of course. At the risk of using the most tired analogy in Cloud Computing, we take our electricity and water as a utility. Of course any organization of sufficient size knows that backup generators may be needed. Or even emergency water supplies.
Now reading all this, you may think you know where I’m going with this “Cloud Bubble” thing. After all, vendors are our cloudwashing all of their products and the potential for an economic bubble is pretty large. but I am actually thinking of a different cloud bubble.
An Architectural bubble.
Much like the idea that everything can be viewed from a single point of view did not work for the SOA era, the idea that everything is in the cloud is equally preposterous. This is a legitimate perspective, as I said in my talk at the Burton Group Catalyst conference it is the perspective of Mr. Magoo.

When we talk about cloud we actually talk about three distinctly different phenomenon.
We have to architect systems differently!

I guess I didn’t take quite the same point from this post that hoolipot did (I thought the “excuse” comment was aimed at opportunistic vendors), but I do agree with his position.
My current experience tells me that the cloud hype is extremely loud and distorted right now. As with most emerging technologies or computing paradigms, the rush by vendors to capitalize on (or, create) new opportunities and by enthusiastic early adopters to try to gain an edge creates lots of confusion and silliness.
There is plenty of value to be gleaned from the cloud movement – even by the implementation of private/internal clouds. And after the cloud vendors and services have matured, they should be a valuable addition to the IT landscape and should be able to fill a variety of roles (some utilitarian). But let’s not rush to try to realize the promised benefits without a clear strategy, planning and risk management.
Just a brief comment about the etymology of the term “cloud.” When we used a “cloud” as a symbol for some entity out on the network, it was because we weren’t concerned with what was in that cloud. Someone else was providing results/output from the cloud that we needed. It didn’t matter how the functionality was implemented as long as it delivered what we needed at the edge (contracts and other means of assuring the usability, quality and usefulness are out of scope, here). Actually, pure SaaS vendors still fall in that category.
Now, as you point out, “Cloud Computing” as we use the term today is quite different. I strongly agree that if you’re hosting your own processes or data in/on a cloud that’s managed and controlled by another party… you definitely need to “worry your pretty little head” about it!!! For example, due diligence and clear, contractual agreement on SLAs is essential (and that’s just for starters).

Hmm - a software company VP proposing that Utility Computing might be a risky choice? Forgive my skepticism, but might Utility Computing actually be more of a risk to the profits of the aforementioned software company?
Miko makes some good points - not everything will work in the cloud, that's for sure. But to describe reduction of operational cost and economies of scale as "excuses" is ridiculous, especially in the current economic climate. These aren't excuses, they are DRIVERS that companies of all sizes are looking to utilize to survive.
Cloud Computing and Utility Computing aren't mature technologies by anybody's standard - but let's continue to develop them rather than badmouth them because of a couple of failures (which weren't even as bad as the internal software failures of most large organizations).
Fact is, enterprises have significant legacy voice infrastructure that’s costly to replace with pure IP solutions. How can we bring this analog infrastructure into our shiny new cloud applications? There are proven methods to bind both legacy voice applications and traditional PSTN audio into cloud-based applications and services at a carrier scale. Some of the most successful implementations leverage WebRTC, WebSockets, SIP and other open source technologies. In his session at @ThingsExpo, Da...

Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...

I'm a lonely sensor. I spend all day telling the world how I'm feeling, but none of the other sensors seem to care. I want to be connected. I want to build relationships with other sensors to be more useful for my human. I want my human to understand that when my friends next door are too hot for a while, I'll soon be flaming. And when all my friends go outside without me, I may be left behind. Don't just log my data; use the relationship graph. In his session at @ThingsExpo, Ryan Boyd, Engi...

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...

Major trends and emerging technologies – from virtual reality and IoT, to Big Data and algorithms – are helping organizations innovate in the digital era. However, to create real business value, IT must think beyond the ‘what’ of digital transformation to the ‘how’ to harness emerging trends, innovation and disruption. Architecture is the key that underpins and ties all these efforts together. In the digital age, it’s important to invest in architecture, extend the enterprise footprint to the cl...

Fifty billion connected devices and still no winning protocols standards. HTTP, WebSockets, MQTT, and CoAP seem to be leading in the IoT protocol race at the moment but many more protocols are getting introduced on a regular basis. Each protocol has its pros and cons depending on the nature of the communications. Does there really need to be only one protocol to rule them all? Of course not. In his session at @ThingsExpo, Chris Matthieu, co-founder and CTO of Octoblu, walk you through how Oct...

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
