What we have seen is that a logically centralized, hierarchical control plane with a peer-to-peer data plane beats full decentralization,” explained Vahdat in his keynote. “All of these flew in the face of conventional wisdom,” he continued, referring to all of those projects above, and added that everyone was shocked back in 2002 that Google would, for instance, build a large-scale storage system like GFS with centralized control. “We are actually pretty confident in the design pattern at this point. We can build a fundamentally more efficient system by prudently leveraging centralization rather than trying to manage things in a peer-to-peer, decentralized manner.
Project Loon by Google - High altitude balloons to provide internet access to everyone
Introducing the latest moonshot from Google[x]: balloon-powered Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill in coverage gaps and bring people back online after disasters.
Many of us think of the Internet as a global community. But two-thirds of the world’s population does not yet have Internet access. Project Loon is a network of balloons traveling on the edge of space, designed to connect people in rural and remote areas, help fill coverage gaps, and bring people back online after disasters.
Google gets how many are still without network connectivity.
The following conclusion to me is incorrect: Google built internal servers and switches and they are using OpenFlow and therefore the companies that build servers and switches will be under enormous pressure from the network DIY movement and most likely will go out of business.
I think the following conclusion is correct: Google built a network that is adaptable to the compute requirements of their business.
Mr. Hölzle said Google would not be donating its networking software to any open source project. “It is very specialized,” he said.
The cost that has been rising is the cost of complexity — so spending a lot of effort to make things not go wrong. There is an opportunity here for better network management and more control of the complexity, and that to me is worth experimenting with,” Hölzle said. “The real value is in the [software-defined network] and the centralized management of the network.
When Urs speaks, datacenter peeps listen.
The problem is we aren’t meeting this challenge. Our infrastructure is broken. Datacenters have the diameter of a microsecond, yet we are still using entire stacks designed for WANs. Real-time requires low and bounded latencies and our stacks can’t provide low latency at scale. We need to fix this problem and towards this end Luiz sets out a research agenda, targeting problems that need to be solved:
* Rethink IO software stack. An OS that makes scheduling decisions 10s of msecs is incompatible with IO devices that response in microseconds.
* Revisit operating systems scheduling.
* Rethink threading models.
* Re-read 1990’s fast messaging papers.
* Make IO design a higher priority. Not just NICs and RDMA, consider CPU design and memory systems.
Google blew this last quarter out, so I took a closer look and noticed a few things:
1. Geographic revenue breakouts are US, ROW, and wait for it, the UK. WTF? Odd.
2. Holy free cash flow batman.
3. The last time I looked (which apparently was about a year ago) Google was spending about $500m a quarter on capital investments. That number is now: “$917 million, the majority of which was related to land and building purchases, and IT infrastructure investments, including data centers, servers, and networking equipment.”
So after a lot of thought, we’ve decided to bid for Nortel’s patent portfolio in the company’s bankruptcy auction. Today, Nortel selected our bid as the “stalking-horse bid,” which is the starting point against which others will bid prior to the auction. If successful, we hope this portfolio will not only create a disincentive for others to sue Google, but also help us, our partners and the open source community—which is integrally involved in projects like Android and Chrome—continue to innovate. In the absence of meaningful reform, we believe it’s the best long-term solution for Google, our users and our partners.
Google takes another potential step in becoming an even bigger force in communications, LTE, and more. Avaya bid $475 and then bought Nortel enterprise coms for $900m after outbidding Siemens. I suspect there may be a few interested parties bidding on the patent portfolio - Cisco, RIM, Nokia, Ericsson, heck, even Apple and Microsoft could end up at the party. Fascinating.
Content creators and distributors are making huge strides in bringing us content in this way, but to do so, many require high-quality video and audio, secure delivery, and other content protection and video optimization technologies. With these tools in place they can easily and effectively give you access to the rich library of content you want to watch, with the immediacy you’ve come to expect.
Google: The Vertically Integrated Content Service Provider?
Nice review of both what Google wants and how 100G is structured.
