Again, the question of reliability is lurking in this article with specific reference to virtualisation and Tier1 app’s …

There is a very simple solution to this problem. If your goal is to provide mainframe-class reliability and operations to virtual resources then consider running a fault tolerant server as the host.

Fault tolerant systems have been available for years – the company I work for has just celebrated its 30th birthday. The technology has been successfully ported and is now used in industry standard server designs and is capable of running your favourite virtualisation hypervisor without any modifications. They are extremely effective and highly suitable for the Tier1 applications mentioned in this article.

Don’t be frightened – you can move them today and enjoy all the advantages of virtualisation.
