The other thing from a CIO perspective is the do more with less mantra. I guess everyone expected the thumb screws to come off when the financial pressures eased [as we began to come out of the global recession]. But they havent in a lot of cases. People are driving their assets within their business much hotter than they would have in the past, and a lot of that is just to maintain profitability within their own business. That puts further pressure on them to deliver what they need, and that pressure gets pushed out into their supply chains, and has knock on effects on their partners et cetera.
The other sides of course, Ive touched on some of them: cost containment; productivitythe whole do more with less; and, business continuity.
So: business demands are increasingly forcing tradeoffs, if you consider the priorities for data centres and networking. You can see that your business people want to deliver a product to market quickly, and they want that product to be beautiful and drive customer demand. Youve also just got to reduce costs at the same time. But the increase in your costs is not offset by an increase in revenue or increase in market share.
Now, if you look at the way networks have been built for more than 10 years, you can see that theyve been built around client-server style technology. An easy way to describe how they work is this: you use a Web browser to interact with servers and you send a request, then the data centre responds. As we bring virtualisation into the network, the challenge is we no longer have just traffic going north to south, but also traffic going east to west because people are virtualising. You might have had a physical server with four applications on it. As you virtualised you put each one of those applications on a different virtual server, and now you have a significant increase in the amount of traffic as applications talk to each othereast to west traffic.
The traditional networking data centre is just not up to the task in all honesty because it was designed for client-server, not designed for applications to talk to one another. The real issues there are it becomes very complicated. And that could potentially raise costs significantly.
If you look at a legacy three-tier data centre, which is what Ive just described, Juniper today has continued to announce things to support what we would term a two-tier data centre, which delivers much higher throughput in the server and the aggregation layout. Up another level in efficiency and flexibility is the one-tier data centre.
