Resumen
In addition to its impact on data centers, virtualization is emerging as a viable technology for smartphones and virtual private networks, as well as being used to reconceive agile and cloud computing. The notion that one of the strengths of virtualization is its ability to isolate data and applications corresponds to another aspect of the technology that has become increasingly popular. While it might be easy to think of virtualization as adding a software layer that requires additional controls to maintain security, proponents of virtualization argue that it serves the opposite purpose, and instead represents a core enhancement to security. Proponents of virtualization say that, in addition to facilitating new ways of enforcing security, virtualization technologies are leading to new ways of distributing software. The big problem with virtualization right now is performance guarantees, says Leendert van Doorn, senior fellow, AMD. In addition to the performance issue, there remains the issue of manageability in the data center and elsewhere.
