It is the infrastructural paradigm shift that is sweeping across the Enterprise IT world, but how is it best defined? I refer of course to 'Cloud Computing' - the phenomenon that currently has as many definitions as there are squares on a chess-board. To try and narrow it down we bring here a round-up of some recent attempts to bring welcome precision where there risks being unnecessary vagueness. Enjoy!
"What is cloud computing all about? Amazon has coined the word “elasticity” which gives a good idea about the key features: you can scale your infrastructure on demand within minutes or even seconds, instead of days or weeks, thereby avoiding under-utilization (idle servers) and over-utilization (blue screen) of in-house resources. With monitoring and increasing automation of resource provisioning we might one day wake up in a world where we don’t have to care about scaling our Web applications because they can do it alone."
"For me the simplest explanation for cloud computing is describing it as, 'internet centric software.' This new cloud computing software model is a shift from the traditional single tenant approach to software development to that of a scalable, multi-tenant, multi-platform, multi-network, and global. This could be as simple as your web based email service or as complex as a globally distributed load balanced content delivery environment.
I think drawing a distinction on whether its, PaaS, SaaS, HaaS is completely secondary, ultimately all these approaches are attempting to solve the same problems (scale). As software transitions from a traditional desktop deployment model to that of a network & data centric one, "the cloud" will be the key way in which you develop, deploy and manage applications in this new computing paradigm."
- Reuven Cohen
"I view cloud computing as a broad array of web-based services aimed at allowing users to obtain a wide range of functional capabilities on a 'pay-as-you-go' basis that previously required tremendous hardware/software investments and professional skills to acquire. Cloud computing is the realization of the earlier ideals of utility computing without the technical complexities or complicated deployment worries."
- Jeff Kaplan
"People are coming to grips with Virtualization and how it reshapes IT, creates service and software based models, and in many ways changes a lot of the physical layer we are used to. Clouds will be the next transformation over the next several years, building off of the software models that virtualization enabled."
- Douglas Gourlay
"The way I understand it, “cloud computing” refers to the bigger picture…basically the broad concept of using the internet to allow people to access technology-enabled services. According to Gartner, those services must be 'massively scalable' to qualify as true 'cloud computing'. So according to that definition, every time I log into Facebook, or search for flights online, I am taking advantage of cloud computing."

I like many of the useful points that people in this article have made about cloud computing. However, I see holes in most definitions for cloud computing. For example, many of the panelists mention that a cloud is tied to the Internet, which is clearly not true with emerging private cloud technologies.
I've put a lot of thought into a definition of cloud computing that I think is accurate, encompassing of evolving trends, and yet simple enough for everyone to understand:
"A cloud is a place where IT resources such as computer hardware, operating systems, networks, storage, databases, and even entire software applications are available instantly, on-demand."
So, let's examine how that simple definition holds up with more specific cloud computing terms.
* Public cloud: places like AWS, Google App Engine, etc. where shared resources are available to any one on demand.
In case anyone is interested, there's a short post at our site that further explains our straightforward approach to defining cloud computing concepts, including other terms not mentioned in this piece such as open vs. closed PaaS.

Kudos to the Cloud Crowd for Re-Inventing the Wheel!
One thing 30 years in the IT industry has taught me is that the more things change, the more they stay the same. Another is that the only memory we seem to access is short-term. A third is that techno-marketeers rely on that, so they can put labels like "revolutionary" and "innovative" on platforms, products and services that are mere re-inventions of the wheel ... and often poor copies at that.
A good example is all the latest buzz about "Cloud Computing" in general and "SaaS" (software as a service) in particular:
Both terms are bogus. The only true cloud computing takes place in aircraft. What they're actually referring to by "the cloud" is a large-scale and often remotely and/or centrally managed hardware platform. We have had those since the dawn of automated IT. IBM calls them "mainframes":
The only innovation offered by today's cloud crowd is actually more of a speculation, i.e. that server farms can deliver the same solid performance as Big Iron. And even that's not original. Anyone remember Datapoint's ARCnet, or DEC's VAXclusters? Whatever happened to those guys, anyway...?
And as for SaaS, selling the sizzle while keeping the steak is a marketing ploy most rightfully accredited to society's oldest profession. Its first application in IT was (and for many still is) known as the "service bureau". And I don't mean the contemporary service bureau (mis)conception labelled "Service 2.0" by a Wikipedia contributor whose historical perspective is apparently constrained to four years:
Instead, I mean the computer service bureau industry that spawned ADAPSO (the Association of Data Processing Service Organizations) in 1960, and whose chronology comprises a notable part of the IEEE's "Annals of the History of Computing":
So ... for any of you slide rule-toting, pocket-protected keypunch-card cowboys who may be just coming out of a fifty-year coma, let me give you a quick IT update:
1. "Mainframe" is now "Cloud" (with concomitant ethereal substance).
2. "Terminal" is now "Web Browser" (with much cooler games, and infinitely more distractions).
3. "Service Bureau" is now "Saas" (but app upgrades are just as painful, and custom mods equally elusive).
4. Most IT buzzwords boil down to techno-hyped BS (just as they always have).

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.

The reason I believe digital transformation is not only more than a fad, but is actually a life-or-death imperative for every business and IT executive on the planet is simple: there will be no place for an “industrial enterprise” in a digital world. Transformation, by definition, is a metamorphosis from one state to another, wholly new state. As such, a true digital transformation must be the act of transforming an industrial-era organization into something wholly different – the Digital Enter...

Application transformation and DevOps practices are two sides of the same coin. Enterprises that want to capture value faster, need to deliver value faster – time value of money principle. To do that enterprises need to build cloud-native apps as microservices by empowering teams to build, ship, and run in production. In his session at @DevOpsSummit at 19th Cloud Expo, Neil Gehani, senior product manager at HPE, will discuss what every business should plan for how to structure their teams to d...

When we talk about the impact of BYOD and BYOA and the Internet of Things, we often focus on the impact on data center architectures. That's because there will be an increasing need for authentication, for access control, for security, for application delivery as the number of potential endpoints (clients, devices, things) increases. That means scale in the data center. What we gloss over, what we skip, is that before any of these "things" ever makes a request to access an application it had to...

In many organizations governance is still practiced by phase or stage gate peer review, and Agile projects are forced to accommodate, which leads to WaterScrumFall or worse. But governance criteria and policies are often very weak anyway, out of date or non-existent. Consequently governance is frequently a matter of opinion and experience, highly dependent upon the experience of individual reviewers. As we all know, a basic principle of Agile methods is delegation of responsibility, and ideally ...

All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of So...

Let's just nip the conflation of these terms in the bud, shall we?
"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.
They are not.
One is about the application. The other, the network. T...

This is a no-hype, pragmatic post about why I think you should consider architecting your next project the way SOA and/or microservices suggest. No matter if it’s a greenfield approach or if you’re in dire need of refactoring. Please note: considering still keeps open the option of not taking that approach. After reading this, you will have a better idea about whether building multiple small components instead of a single, large component makes sense for your project. This post assumes that you...

DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO’s chair will come from the IT leaders that successfully ma...
