Head in the Clouds?

Posted May 10, 2009 7:25 AM

Cloud computing (some call it utility computing) offers the potential of third-party suppliers being able to host certain applications for customers. Theoretically, some sort of factory control system could be remotely hosted in this way. Do you see a future in cloud computing for factory control and automation? Would there be high interest in gaining application services without necessarily investing in a lot of infrastructure (such as a server and the software for the automation program)? Or do you feel such a control system is too important to outsource to an outside host? Do you see possible security issues in relying on cloud computing?

this will work if you have the internet bandwidth so the application will be as fast as it would be on your hard drive and have the memory to handle the sizable local files that are there to reduce bandwidth demands. So you want to do a photoshop pix edit? You would need the cloud to have a legal cloud version of photoshop ( I can see Adobe being happy about that and wanting a per cloud user/file fee) or something that does the same, that the cloudco owns.

Now local ISP's will want to sell their cloud services and might throttle traffic to free floating clouds for selfish reasons as they do for VOIP and distributed file transfer services(the 5% of legal ones).

So is the pipe from you to cloud and back fast and open?

I can see cloudco having a sea of computational nodes = all open source stuff = your guys will need to cross train from Word, excel, Photoshop etc to the open source equivalent to make it cost less and work fast.

1. You have to go a whole lot further to convince me that "Cloud Computing" is anything more sophisticated than the old model of the central computer and dumb terminals. I remember what a tremendous improvement we all thought it was to finally have some serious computing power on our desks. Now you want to take it away from us???

2. Anything critical should never, ever be connected to the Internet, and one must be very careful not to allow inadvertent access to one's critical systems connected to a LAN. Process controls, especially where a threat to life or public health is in question, should never, ever be connected to ANY network. Any computer containing any sort of sensitive information should never be connected to the Internet, and one needs very, very good defences to insure no unauthorized access over a LAN that may have a port open somewhere to the Internet.

The Internet is too easily disrupted by those with spacious intentions, international spies, and other such malcreants to ever be considered a medium appropriate for anything much more critical than playing World of Warcraft or searching Wekipedia for general knowledge (which, of course, should be viewed as spurious until one has the opportunity to verify the claims in the laboratory).

"Cloud Computing" is, in actuality, a smoke screen intended to camoflage the fact that the computer industry is totally out of touch with reality...

For process control? Not no way, not no how. Never. Period.

If a manager wants to slow down the office computers, and compromise their security to save a buck, I will let him. My plant computers? No. I will fight that one all the way. And I will win. If I don't win, then they will eventually lose. Big time.

Central computing re-visited on a faster more crowded pipeline. With all the hiccups in networking and especially the Internet - I want my processes controlled locally.

Hi all,

This is purely my own opinion about the stupidly named "cloud computing".

It sorta goes like this..................Some, somewhere, needs to keep some sort of 'memory bank', whether that is the 'conventional' web server which contains HDD and or any other Memory saving stuff is not important. But the knowledge which will and is spread through the web via memory on the web and perhaps to a larger degree, to memory on personal computer, has to saved, to allow information to be searched for and gathered.

CLOUD computing, is just a silly name to move memory and information onto the web. People will still need/want their own memory bank of info' which will be kept on their own computer.

I cannot see the idea of any factory being programed from on high so as to speak, because how and who is going to guarantee the truth and safety of any info spread in this way?

The idea is perhaps feasible and is currently used for music and video media. But for anything of 'real importance' I cannot trust someone else, (as you would need to do) to take control of the way I live other than the way I deal and use music and video, which by comparison to the threads original question, is completely unimportant.

Imagine the plans and working schedule etc, for an Aircraft or Defense System. To put the running of a remote operator, into the hands of a different remote operator, which in turn with direct the complete info' of how to run a factory, Aircraft builder, or army into the 'clouds' is ridiculous in the extreme. The running of even the simplest of factories, needs to be a 'hands on operation', where charges in people, whether they are sick etc, in alterations to any building, to make more space, and a million other things, must be controlled by people on the ground in the factory and 'locale' .

I have said enough. I think the question was silly in the extreme and was probably thought up by someone with nothing better to do or, that someone may have been sponsored by Apple and or intel, or, windows Corp.

from Sleepy,

Guys, we have to fight cloud computing all the way to a glorious, or inglorious death.

Cloud computing can only be more dangerous ( security risk!!) than the utilisation of individual workstations. It can only be more dependent upon the links than the workstation/network and hence more likely to be a major risk in getting any task completed.

Security vulnerabilities are enhanced considerably.

Can we rely on the cloud; how and why?

Years ago I found that one of our labs had decided to invent its own LAN - for its own security reasons. I railed against it - I was supposed to be in charge but they had gone so far down the track.....

The first majot job came up a major bid to our best customer, hours were worked until no one had any sleep and then came the big moment, we started to print the final document. Kelly hit the print button first and all the other machines locked up for three hours whilst her contribution printed! Yes, the document was that big and the network was so small and so poorly engineerred 'cause that was all that they could afford out of a non existent budget!

Don't ever mention Networked computing to me without a proper size consideration.

And as for cloud computing!!!

We can never go there without some absolutely tremendous risks, who could buy this when there are so many time and security dependent tasks to be achieved.

Sleepy
