Here is an expanded outline of the basic architecture of our approach to High-Availability (HA) clustering. Overview In any HA deployment there are two main components: hosts and guests. The hosts are the systems which are the core of the cluster itself. The host runs with very limited services dedicated for the use and functioning of the cluster. The host systems handle resource allocation, from persistent storage to RAM to the number of CPUs each guest gets. The host machines give an “outside” look at guest performance and give the opportunity to manipulate them from outside the guest operating system. This offers significant advantages when there are boot or other failures which traditionally would require phys... (more)

Contributing to FOSS: A Business Perspective

The talk also reviewed some... (more)

Attending the Ubuntu Developer Summit in Budapest

On Saturday, May 7th, I’ll be taking a flight out to Budapest, Hungary to attend the week-long Ubuntu Developer Summit (UDS) as the kick-off event to the development of the next Ubuntu release, 11.10 (code name Oneiric Ocelot) coming out in October 2011. The Ubuntu Developer Summit is the seminal Ubuntu event in which we define the focus and plans for our up-coming version of Ubuntu. The event pulls together Canonical engineers, community members, partners, ISVs, upstreams and more into an environment focused on discussion and planning. My role at these summits as an Ubuntu Commu... (more)
