Win Treese interviewed me and my co-authors about the book.

An Interview with the authors of "The Practice of Cloud System Administration" on DevOps and Data Security

We discussed DevOps in the enterprise, trends in system administration, and at the end I got riled up and ranted about how terrible computer security has become. has published an excerpt from our book "The Practice of Cloud System Administration: Designing and Operating Large Distributed Systems Vol 2".

The article has a title that implies it is about capacity planning for data centers but it's really about capacity planning for any system or service.

Room to grow: Tips for data center capacity planning

If you like that it, there's 547 more pages of good stuff like that in the book.

When Esther Schindler asked for permission to publish an excerpt from The Practice of Cloud System Administration on the Druva Blog, we thought this would be the perfect piece. We're glad she agreed. Check out this passage from Chapter 7, "Operations in a Distributed World".

If you manage a sysadmin team that manages services, here is some advice on how to organize the team and their work:

Next week marks the 20th anniversary of the "big" Synopsys downtime of November 18-20, 1994. It was the most ambitious one we attempted while I was at Synopsys -- a complete reconfiguration of the network in one weekend. It was also the first one we planned and carried out using the flight director and mission control model that Christine and Tom later made known to a wider audience in The Practice of System and Network Administration.

Although not all of you were working at Synopsys in 1994, this is probably the best chance I'm going to have to thank all of you for what you contributed to the downtime process. It was a real highlight of my professional career.

PS If any of you still have digital photos of any of the downtimes, I'd appreciate it if you could share them.

If you have digital photos from that event, please contact Paul. If you don't have contact info for him, please post a comment.
