The
Availability Digest is published by Sombers Associates, Inc. We
have been active in mission-critical, high-availability
solutions for over forty years.
The Managing Editor of the Availability Digest is Dr. Bill
Highleyman. He
brings decades of experience to the design and implementation of
mission-critical computer systems. As Chairman of Sombers
Associates, he has been responsible for implementing dozens of
real-time, mission-critical systems such as Amtrak, Dow Jones,
Time, McGraw Hill, Tandem, Federal Express, Chemical Bank, SIAC,
Smith Kline, G. E. Credit, Southeast Bank, A. C. Nielson, and
Harris Satellite. Currently, Dr. Highleyman is active in the
following areas:
authoring and publishing
technical articles, white papers, specifications, and patent
applications (self-bylined and ghostwritten for others),
developing and teaching
seminars on a variety of topics to both online and in-house
audiences,
achieving extreme
availabilities with active/active systems,
and analyzing the
performance of real-time systems.
Dr. Highleyman received his undergraduate degree
(BSEE) in Electrical Engineering from Rensselaer Polytechnic
Institute, his MSEE from the Massachusetts Institute of
Technology, and his DEE from New York Polytechnic Institute.
Dr. Highleyman has published
extensively on availability, performance, testing, middleware,
and other technical topics. He is the author of "Performance
Analysis of Transaction Processing Systems," published by
Prentice-Hall, and is co-author of the three-volume series,
"Breaking the Availability Barrier." The books are available at
amazon.com and at Barnes & Noble.
