Sometimes a particular job requires a lot of resources and other times it doesn't. Using VM images makes it easier to spin up new instances to handle the workload and shut it down when the job is done.<br />One reason businesses use public clouds for non-sensitive data is cost and time. Many companies can't afford to pay Level3 for 100 full racks, and the resources to manage them. Even if a company can afford it, do you really want to buy and maintain 1000 nodes just to handle a sudden spike in load during the holiday?<br />Security is always a pain and it's always in favor of attackers. I know from my college days just how easy it is to hack/attach a network. That is a different problem than whether or not a business should use a cloud. I'm using rackspace and EC2 these days to host demo apps. It is considerably cheaper than buying 40 servers and hiring a fulltime unit admin to maintain them.woolfelhttps://www.blogger.com/profile/13814445471254728002noreply@blogger.comtag:blogger.com,1999:blog-6947769630065163891.post-88747099008598555412012-04-25T14:52:08.770-05:002012-04-25T14:52:08.770-05:00@Peter: True... but Why?

If you believe even 10% of what TV shows would have you believe (when they are still using 19" CRT displays) then cracking an internet message IP source and destination is a piece of cake/pie. <br /><br />20/20 did a piece one night on this where a guy drove down Wall Street and cracked bank after bank after bank with a laptop and it took him, at most, five minutes with some and at best one minute or less with most. That alone was enough to convince me that I didn't want wireless anywhere near my place of business and I have absolutely NOTHING of value to anyone. I just don't believe in wireless when you don't need it. EMail, blogs and such have to be internet. My real stuff is separate on a machine that is NOT connected to the internal network that is connected to the external internet. Paranoia? You're not paranoid if they really are out to get you. :-)<br /><br />SDG<br />jcoJames Owenhttps://www.blogger.com/profile/09329916624230570826noreply@blogger.comtag:blogger.com,1999:blog-6947769630065163891.post-82640926516448453592012-04-25T14:43:21.852-05:002012-04-25T14:43:21.852-05:00Business are using the cloud, but a lot of it is f...Business are using the cloud, but a lot of it is for data that is not sensitive. Businesses that have strict security requirements tend to go with a private cloud. One example is the military uses VMWare to spin up instances when the load demands it. Since military applications have crazy security requirements, they have their own private could.<br /><br />Tibco hype is the usual business hype. Every business does it, even if it's silly and non-sensical.woolfelhttps://www.blogger.com/profile/13814445471254728002noreply@blogger.com
