IBM At the Hot Chips 2010 conference, IBM announced their upcoming z196 CPU, which is really, really fast. How fast? Fastest chip in the world fast. Intended for Z-series mainframe computers, the Z196 has a clock speed of 5.2GHz. Measuring just 512 square millimeters, the Z196 is fabricated on 45nm PD SOI technology, and on its surface contains almost one and a half billion transistors. My... Processor is bigger than yours.

With the rise of cloud computing I wonder whether we'll see a massive resurgence in mainframes and big iron boxes? the great thing with these massive mainframes is not only their grunty processors but massive bandwidth that can move huge amounts of data being moved around and rock solid reliability.

I doubt it, I think it's cheaper, more flexible and makes more sense to use a cluster of small processing nodes, rather than a single large system. I think the reason why there is still a market for large mainframes is due to legacy software that cannot function in a distributed fashion.

Actually it's probably the other way around.

The mainframes don't need an interconnect (or it's build in and fast, however you look at it). Thus it would probably be very good at pushing data around.

IBM mainframe sales actually are going up, part of the reason is because people don't want to rely on Sun anymore since it was bought by Oracle.

I hear a mainframe is also very good at running many Linux machines. Uses less power than a cluster of machines and is fully redandant as wel.

Just is not everyone can pay a milion to run a 'few' Linux-servers.

Who are the biggest cloud companies now, and how are they doing it?

Google
Amazon
Microsoft
Facebook
Twitter

I believe all of them are using the multiple cheap server route. They aren't all forthcoming with their methodology or reasoning for their architecture, but I think that leads me to think that Mainframes don't look like they'll have much of a future in cloud computing.

Of course, I trust my own predictions in technology less than I do the weatherman's daily forecasts. But if I had to make a bet, I wouldn't bet on clouds in big iron.

Doubtful. The cost is very high. That's part of why companies like, say, Google, don't even consider them for their grunt work. if I were coming up with something scalable, today, I'd be looking at many cheap boxes, and handling fault tolerance with a proxy layer that caches workloads until they are sent back complete, with as much testing of data correctness as seemed reasonable (FI, if scaled out enough, sent each workload to two machines, and verify CRCs on their results, before returning the results).

There will be a continued demand for big iron (sometimes you'll just need throughput...and maybe need to run legacy code that isn't x86), but I don't think anyone will be moving towards them in any large numbers. Atom and Bobcat derived servers are much more the future, even if you treat cloud computing as a fad.

Atom and Bobcat are the future for non critical applications out there. IBM's superb big iron will still be needed where precision is paramount.
Last time I checked, Google does not run it's accounting on their cloud systems, because they need precision.
