What we’re about
BayLISA is the premiere system administration user group in Silicon Valley and the San Francisco Bay Area. Founded in the very early 90s after the fourth Large Installation System Administration (LISA) conference, BayLISA has supported and educated systems, network, storage, virtualization, and other technology professionals in the Bay Area for over 20 years.
We use Meetup to coordinate meeting attendance, announcements, and reminders. We have our official organizational presence on the web, including links to membership, sponsorship, and mailing lists, at www.baylisa.org.
Our legacy description:
One way to put it is that there are many user groups, but we are the sysadmins group. BayLISA includes system and network administrators across a range of skill levels. BayLISA meets monthly to discuss topics of interest to administrators and managers of sites supporting more than 100 users and/or computers. The meetings are free and open to the public.
BayLISA grew out of an after-hours discussion among attendees of the USENIX LISA IV conference. The idea was to provide a forum for Sysadmin professionals in the San Francisco Bay area to get together and exchange ideas, hear speakers address topics of interest and most importantly, socialize.
BayLISA stands for: Bay Area Large Installation System Administrators

See all- Making the DNS an app-reliable ServiceKoll Oakmead Park, 3350 Scott Blvd Building 54, Santa Clara, CA
Abstract:
During the last five-ish years of my tenure at LinkedIn, my team noticed that we were tracing most “it’s the DNS!” issues down to a couple root causes—client library behavior, and nscd. Each of these incidents kicked off a mad scramble by the team, checking graphs of named stats collected periodically & shipped to our standard metrics service; manually executing batches of test queries against each nameserver live in the appropriate pool; and manually executing various other tooling we’d developed over our years of experience with the DNS to identify any misbehaving nameservers. We got to thinking “there must be a better way”—which led to discussions with partner teams, which led to ideas, research, and eventually to an action plan: we needed to develop our own client-side hostname cache service—and thus DCL was born.This talk is based on a recent LinkedIn blog post, https://www.linkedin.com/blog/engineering/infrastructure/building-a-resilient-dns-client-for-web-scale-infrastructure. I'll provide some details of how we arrived at the decision, features of DCL, and the benefits we got from it over what alternative off-the-shelf products would have provided.
Speaker Bio:
Guy B. Purcell, Ph. D. received his doctorate in astrophysics from the University of Alabama in 1998. Getting there required him to learn a bit of UNIX system administration, which he eventually spun into a second career, most recently with LinkedIn for almost 17.5 years (his longest stint; his shortest was three days with Taos Mountain). Dr. Purcell is currently Treasurer of BayLISA and dog-sitting for his son hiking the PCT, while he decides what "career three" will be.Timing Details:
