Observation: Cloud computing is nothing new

Cloud computing is not only the latest buzz term, it might well be the model of computing that powers the 21st century. However, it’s easy to forget that personal computing, in which each user has a standalone system that can operate without a network, is itself a relatively new approach.

The first practical computers were enormous behemoths composed of clicking relays and vacuum tubes. Much of the early development of these multi-ton monsters had been spurred by the allied code-breaking effort during World War II. For the first thirty years of the history of general purpose computers, computer time was the exclusive privilege of large institutions and governments. 

One of the first breakthroughs in bringing down the cost of computer access was the concept of a time-sharing system. In such a system, multiple operators can access the resources of the computer through the use of remote terminals. Here, in the form of early Teletype terminals, and later, video terminals, we see the emergence of a network topology in which computing horsepower is located in a central computer, away from the user.

It was the era of the mainframe and the dumb-terminal. Typically, these dumb terminals would lack storage or computation capability, as they were simply a display with a keyboard. By the 1970s, an operator (usually wearing flared trousers, if the textbooks I’ve seen are accurate), would sit in front of an amber or green screened terminal, thankful that he no longer needed to wait in line in to hand in a box of carefully arranged punch-cards.

Fast forward to the late 70s and a new paradigm was beginning to gain favour. If you’ve seen the film The Pirates of Silicon Valley, a dramatisation of the early years of Apple Computers, you may remember a scene in which the young Steve Wozniak is compelled to show his prototype personal computer to his employer, Hewlett Packard. In the scene that I’m talking about, Steve fears that his bosses will take his idea from him. The exchange goes something like this:

HP exec
Steve, it is Steve isn’t it?

Steve Wozniak
(nods)

HP exec
Steve, you say that this... gadget... of yours is for ordinary people. What on earth would ordinary people want with computers?

(long pause)

The idea that was being mooted was that of a personal computer, that is, a self-contained computer that only requires an electrical power supply in order to operate. Singular computers that did not need to be connected to a larger computer in order to run went on to become the popular face of computing for the remainder of the 20th century.

Ever since its establishment, the personal computer suffered a minor, organised assault by companies who had started calling terminals thin clients. These companies, such as Oracle and Sun, met with only limited success over the course of the 1990s. However, sometimes a good technological idea comes along, but suffers because it arrived at the wrong time. For example, consider Apple’s first attempt at a hand held computer, the ARM powered, touch screen equipped Newton. People accuse Apple of simply repackaging existing ideas in the form of the iPad, but they were pioneers in hand held computing 15 years ago. 

The latest incarnation of the overall idea, of separating the storage and processing power from the user's point of access, is called cloud computing. Cloud computing will probably be successful to some degree because it benefits from the most powerful but mundane natural force there is: evolution. The computing environment has changed and people have decided that they want what cloud computing has to offer. What’s more, they’re willing to give up some of the benefits of true personal computers to get it. It will take a while, but already, people are starting to recognise the advantages of a cloud style solution such as Google Mail and Google Docs.

So, take my advice: in a few years time, when a young, hip kid tells you about the new idea in computing, to have self contained computers with local storage and processing power, try to look surprised.

Best info on cloud computing

Cloud computing India's picture

Yes, cloud computing now days very popular among companies. Many companies moving their servers on cloud computing. But security issues are some drawbacks and that's why small companies not taking cloud computing seriously.

Thanks.

advantages?

re: "the advantages of a cloud style solution such as Google Mail and Google Docs"

this is a fool's paradise

i'll stick to an email client under *my* control
and keep *my* docs local

the only advantage of 'cloud computing' is in the platform as service area,
here it becomes possible to 'rent' computing resources far more cost effectively than owning them fulltime, if one doensn't need them fulltime

even there, however, security, reliability, and control are still fundamentally important issues

trust google? microsoft? never mind kool-aide, you're smoking crack, bro

Everything old is new again...

Yes, the glass house is back. Bigger and more impervious than before. But with some interesting potential that I will try and tackle in a post in December.

Yes, arriving at the end... autonomous PCs being underdeveloped and "pay per use" of the "cloud".

The wet dream of a monopoly! Pay per use!

Silicon or Silicone ?

Thin client sharing 'app'

Thin client sharing 'app' from mainframes over ethernet is older than Apple. I can't believe how LJ stuck on Woz !

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
