I’m not sure why it all happens at once but it often does. Last Monday I kicked off HPTS 2011 in Asilomar California and then flew to New York City to present at the Open Compute Summit. I love HPTS. It’s a once every 2 year invitational workshop that I’ve been attending since 1989. The…
Sometimes the most educational lessons are on what not to do rather than what to do. Failure and disaster can be extraordinarily educational as long as the reason behind the failure is well understood. I study large system outages, infrastructure failures, love reading post mortems (when they actually have content), and always watch carefully how…
Earlier today we lost one of the giants of technology. Steve Jobs was one of most creative, demanding, brilliant, hard-driving, and innovative leaders in the entire industry. He has created new business areas, introduced new business models, brought companies back from the dead, and fundamentally changed how the world as a whole interacts with computers….
The Amazon Technology Open House was held Tuesday night at the Amazon South Lake Union Campus. I did a short presentation on the following: • Quickening pace of infrastructure innovation • Where does the money go? • Power distribution infrastructure • Mechanical systems • Modular & Advanced Building Designs • Sea Change in Networking Slides…
Earlier today Alex Mallet reminded me of the excellent writing of Atul Gawnade by sending me a pointer to the New Yorker coverage of Gawande’s commencement address at the Harvard Medical School: Cowboys and Pit Crews. Four years ago I wrote a couple of blog entries on Gawande’s work but, at the time, my blog…
As a boater, there are times when I know our survival is 100% dependent upon the weather conditions, the boat, and the state of its equipment. As a consequence, I think hard about human or equipment failure modes and how to mitigate them. I love reading the excellent reporting by the UK Marine Accident Investigation…
For those of you writing about your work on high scale cloud computing (and for those interested in a great excuse to visit Anchorage Alaska), consider submitting a paper to the Workshop on Data Intensive Cloud Computing in the Clouds (DataCloud 2011). The call for papers is below. –jrh ——————————————————————————————- *** Call for Papers ***…
I’m dragging myself off the floor as I write this having watched this short video: MongoDB is Web Scale. It won’t improve your datacenter PUE, your servers won’t get more efficient, and it won’t help you scale your databases but, still, you just have to check out that video. Thanks to Andrew Certain of Amazon…
I’m taking some time off and probably won’t blog again until the first week of September. Jennifer and I are taking the boat north to Alaska. Most summers we spend a bit of time between the northern tip of Vancouver island and the Alaska border. This year is a little different for 2 reasons. First,…
A couple of days ago I came across an interesting article by Microsoft Fellow Mark Russinovich. In this article, Mark hunts a random Internet Explorer crash with his usual tools: The Case of the Random IE Crash. He chases down the IE issue to a Yahoo! Toolbar. This caught my interest for two reasons: 1)…
PUE is still broken and I still use it. For more on why PUE has definite flaws, see: PUE and Total Power Usage Efficiency. However, I still use it because it’s an easy to compute summary of data center efficiency. It can be gamed endlessly but it’s easy to compute and it does provide some…
Federal and state governments are prodigious information technology users. Federal Chief Information Security Office Vivek Kundra reports that the United States government is spending $76B annually on 10,000 different systems. In a recently released report, State of Public Sector Cloud Computing, Vivek Kundra summarizes the benefits of cloud computing: There was a time when every…
Economic forces are more powerful than politics. Political change is slow. Changing laws takes time. Lobbyist water down the intended legislation. Companies find loop holes. The population as a whole, lacks the strength of conviction to make the tough decisions and stick with them. Economic forces are far more powerful and certainly more responsive than…
There have been times in past years when it really looked like we our industry was on track to supporting only a single relevant web browser. Clearly that’s not the case today. In a discussion with a co-working today on the importance of “other” browsers, I wanted to put some data on the table so…
We live on a boat which has lots of upside but broadband connectivity isn’t one of them. As it turns out, our marina has WiFi but it is sufficiently unreliable that we needed another solution. I wish there was a Starbucks hotspot across the street – actually there is one within a block but we…
I’m on the technical program committe for ACM Science Cloud 2010. You should consider both submitting a paper and attending the conference. The conference will be held in Chicago on June21st, 2010 colocated with ACM HPDC 2010 (High Performance Distributed Computing). The call for papers abstracst are due Feb 22 with final papers due March…
