Lew Tucker’s Keynote Speech at Cloud Connect 2011

Cloud must be getting a lot of attention, because all the sessions at Cloud Connect were packed with a lot of people—sometimes I could not find a seat. I will write a few blogs about some of the more interesting sessions as they relate to energy efficiency.

Lew Tucker, formerly with Sun and now with Cisco, is an excellent speaker and very knowledgeable. Being knowledgeable does not always make one a good speaker. In the case of Lew, he satisfies both traits and did not betray my expectation this time, either.

Sun used to say that the network is the computer. Now Cisco is saying that. As we add mobile devices, sensors (components at home, commercial buildings, and industrial entities), and interactions with car components, the number of addressable components online will increase from roughly 5 billion now to 50 billion by 2020 (by some estimates). And the day will come soon, before we know it, when 1 trillion connected devices, 1 million applications, and 1 zettabyte of data is common.

By the way, 1 trillion is 1,000 billion. Zetta? Let’s see. Giga is 10 to the 9th power, tera is 10 to the 12th power, peta is 10 to the 15th power, exa is 10 to the 18th power, and zetta is 10 to the 21st power.

As so many elements are connected to the Internet, how do we cope with them? The answer is cloud computing. Lew explained the legacy data center and cloud data center.

Legacy data center (slide from Lew Tucker’s speech)

In the traditional data center, each application is tied to a physical server; thus when you add an application, you also add hardware and complexity. In the cloud data center, you do not need to add hardware, even if you add more applications, and therefore it is more efficient.

Lew’s speech can be seen here (running time: about 14 minutes). It is worth your 14 minutes. His presentation is available here for free.

OK, this blog is all about energy efficiency. How is his speech relevant to that? IT or data centers are often to blame for their power consumption. If the 1 trillion, 1 million, and 1 zetta situation becomes a reality, how much more power will be consumed in the legacy data center? In the cloud data center, redundant hardware and software (by way of service-oriented architecture, or SOA) will be eliminated, and more energy efficiency will be established.
