Summary
The most important advancement in twenty-first century computing technology has been the inception and maturity of virtualization, more precisely VMware vSphere. At this point in the evolution of the industry, it is indisputable that 99.9% of all database or data management systems should be considered candidates for virtualization on vSphere. Oracle databases and software are prime candidates to consider migrating to virtualized infrastructure. Subsequent chapters discuss the ever-evolving role of the DBA, which will be delivered with a heartfelt admonition: to consider the direction of technology growth and the projection of your own position in the next decade. Only one conclusion is rational because only one path is sustainable: Embrace virtualization as the next phase of the ever-expanding province of the DBA or face obsolescence.
