Resilient Systems — Part Two: Highly Available Services under Linux and VMware

Brown Bag Lecture by Michael Kushnir | 11/22/2011 11AM-12PM | 7th Floor Conference Room, Bldg 38A

Abstract: In the age of open source everything and 99.99% uptime guarantees, highly-available fault-tolerant system architectures have become essential. Tighter budgets have rendered downtime due to maintenance or failure unacceptable, while also requiring alternatives to expensive proprietary technologies. Thanks to free operating systems and open source software, enterprise-grade fault tolerant systems can now be built for the cost of bare metal. This two-part lecture will discuss tools and implementation scenarios for building resilient systems that can sustain multiple failures without downtime, focusing specifically on cluster architectures based on open source software, an example being CEB’s OPENi virtualized distributed computing architecture. The second lecture will focus on free and open source high-availability tools available for Linux and proprietary tools included in VMware vSphere.

Bio: Michael Kushnir joined the Communications Engineering Branch of the Lister Hill National Center for Biomedical Communications as a system architect and administrator in November, 2010. Michael specializes in RHEL/CentOS and VMware vSphere administration. Prior to NLM, Michael was head administrator for internet startups AdGlobalMedia.Com and YouSeeAds.Com where his work focused on low-cost, fully-redundant, and infinitely-scalable systems. Michael has fifteen years of experience in Windows administration and five years in Linux administration working mostly with free RHEL clones such as CentOS, OpenFiler, and etc…

Michael received a B.S. degree in Management Science from Johns Hopkins University in 2004 and a J.D. from the University of Baltimore School of Law in 2010. During his academic pursuits, Michael has conducted primary research on the feasibility of slots in Maryland for the Maryland House of Delegates Ways and Means Committee, and on banking law and regulation in the U.A.E.
