标签: cloud computing

You probably know that the "cloud" and cloud computing are hot items this year, unless you've been stuck in cave or under a rock. Apple's recent announcement reinforced how the cloud has captured imagination and media buzz. Closer to the engineering side, the June 2011 issue of the publication Desktop Engineering —which focuses on CAD, CAM, FEA, mechanical modeling, fluid and thermal dynamics, simulation, and rapid prototyping—was devoted to the subject, with articles on how cloud computing will (mostly positively) and affect these disciplines. What do I think about the cloud's true potential? To be honest, I don't know yet, one way or the other. Here's why I am ambivalent: every year, there is a topic or trend (or two or three) which the pundits and media say is the "next big thing." The hype machine goes into overdrive and we hear and see it everywhere. Sometimes it is so; more often it is not. But what bothers me is that this next "big thing"—whatever it is—is somehow postulated as the solution to all problems, whatever the problem actually is. One year it's Twitter, before that we had wikis, we've also had multicore processors, tablet computers, and social media. The list of hot items that will solve all your problems goes on and on. Somehow, all problems map to this hot solution, and you can project onto it whatever you are looking for, as it leads you along (or you are led by it). Just be patient, they say: once this next big thing is properly implemented, then it will really, truly be the ideal solution for whatever ails you. People who a few months ago couldn't spell the word "cloud" are now touting its inestimable virtues and benefits. I suspect the cloud and cloud computing will become another useful option and tool, one which engineers and businesses will choose when appropriate and suitable. It will not erase all previous storage/computing schemes. It will have its own set of virtues, vices, and tradeoffs which users will weigh as they decide if it matches their needs and priorities. The cloud euphoria is closely related to another five-letter word I see in press releases: "ideal." When the announcement says the product is ideal, it should mean that all similar products will soon be wiped off the market, like the dinosaurs they will have become. Yet despite press releases to the contrary, I'm still waiting for the ideal op amp that obsoletes thousands of others , but I a not holding my breath. Similarly, despite the accolades and promises (plus wishful thinking and marketing hype), the cloud and cloud computing are not ideal. They may, however, be well suited and a good choice for certain situations, and that's reasonable to expect. Excessive hype does no one any good, except journalists who need something to write about, and those hoping to cash in for a quick buck. Readers : What "next big thing" that will solve all your problems do you recall? And what happened to it?

According to an entry on Wikileaks and other sources, hackers broke into a database used by pharmacists in Virginia, US last April 2009. Eight million records were deleted. The bad guys are demanding a $10 million ransom to return the data. They claim to have deleted the backups, too. One could rant about poor security practices that left the data vulnerable. But what I find appalling, assuming the claim is correct, is the apparent lack of adequate and safe backups. I really shouldn't be surprised, as many of us—way too many—do a poor job insuring there's a safe copy of our digital data archived. I hear constantly from developers who are losing weeks and months in recreating missing source code. A few years ago, a company informed me they were shutting the doors due to a fire in the engineering department that took out their source code; no off-site backups were maintained. My computer-illiterate brother has lost all of his pictures, twice, due to hard disk crashes, yet he still refuses to get serious about a simple backup solution. One would think a single bad experience would be reforming; to have had this happen twice and still not take preventative measures boggles the mind. The most important asset many companies posses is their data, whether that's customer files, source code, or accounting files. Yet in far too many you're liable to get in trouble for defacing an unimportant asset—like a desk—while the data is vulnerable to hackers, fire, or an rm "r *.* from an angry laid-off worker. Once we were told to keep an off-site backup. That is no longer good advice. We learned from Hurricane Katrina that it's possible to lose an entire city. Keep a backup a kilomile away. In this day of cloud computing that's simple and cheap. We paint our houses to preserve them. Change the oil in the car to keep it running well. Owning anything implies a level of responsibility, and that, too, is true of computers. Even a ma and pa shop needs effective backups. Your home data, those pictures, music and other records, need to be archived frequently and safely. How do you protect your data?
