We have two talks for this month!...
The first is Commodity Hardware Era - Tackling the Reliability Challenge by M. C. Srivas.
"In the age of commodity hardware, building a distributed system that is ultra-reliable is challenging. The presentation shows how MapR is able to achieve 100x better reliabilty for its Hadoop and HBase NoSQL products compared to even commercial NAS, database and storage vendors."
M. C. Srivas is CTO and Co-Founder, MapR Technologies. Prior to co-founding MapR, Srivas ran one of the major search infrastructure teams at Google where GFS, BigTable and MapReduce were used extensively. He wanted to provide that powerful capability to everyone, and started MapR on his vision to build the next-generation platform for Big Data. His strategy was to evolve Hadoop and bring simplicity of use, extreme speed and complete reliability to Hadoop users everywhere, and make it seamlessly easy for enterprises to use this powerful new way to get deep insights. Srivas brings to MapR his experiences at Google, Spinnaker Networks, Transarc in building game-changing products that advance the state of the art.
The second is "What has changed?": Using Git Or Svn To Document System Configurations by Robert Harker.
Every Linux environment has a few pet configurations. The one off servers that either predate your system automation or are just more convenient to manage by hand. How do you document these systems in a consistent reliable way that allows changes to be viewed through time? What about your legacy systems? How do you determine what changes have been made to create its unique configuration?
Git or svn can be used to track changes in a system's configuration. Each set of changes gets checked into a repository. Changes to the system trough time can be viewed with standard tools like gitk. This strategy can be expanded track a collection of related servers. Finally git or svn can be used to audit an existing system to find what files have been modified prior to a system upgrade.
Robert Harker is a long time member and former board member of BayLISA who is currently interested in OpenStack and Continuous Integration.
Our meetings are scheduled for 7:30pm on the third Thursday of each month, at Yahoo's 700 1st Ave building in Sunnyvale (near Moffett Field, Juniper, Weird Stuff, and the Sunnyvale water plant/landfill).
BayLISA includes system and network administrators across a range of skill levels. BayLISA meets to discuss topics of interest to system administrators and managers. The meetings are free and open to the public.
We always welcome presentation topics and volunteer speakers. Use the "Contact us" link on this page to get in touch with BayLISA's directors.
