My first impression? I thought it wasn't a good plan to put all your eggs in one basket. I still get that a lot from potential users. It represents a misunderstanding of what virtualization is all about.
Jay Pritchett, Director of Engineering at Altran North America.
One of the best things about working at Avid is learning more about process control from some of the smartest people in the industry. Recently, we spoke with industry-leader Jay Pritchett about physical-to-virtual (P2V) migrations in process control. Despite all the benefits of virtualization, only a fraction of industrial systems have been converted to run on virtual machines. There are good reasons to be cautious. You can read more from our conversation, and get some tips on when you should migrate a control system, at Automation World Magazine's web site - 4 Tips for P2V System Migrations. This is a sequel to 3 Tips for Safe and Effective Virtualization published by Automation World in their August issue. Both articles are a part of the Control System Integrator Association's (CSIA) guest blog series. We highly recommend the entire series.
If you haven't already installed a virtual process control system, the chances are that you will soon. Virtualization, particularly platform virtualization, has swept through process control at a speed that would have been difficult to believe a few years ago. But are these systems as safe and effective as they could be?
While attending the ISA Cybersecurity Conference last month in Detroit, it occurred to us that cyber and other process control trends can overlap with virtualization in surprising ways. That's the topic of a blog post we wrote for Automation World, which came out today: Three Tips for Safe and Effective Virtualization. It includes some great advice and insights from one of the real luminaries of process control, Matt Gibson of the Electric Power Research Institute (EPRI).
While you're at the Automation World website, check out Troy DeHart's excellent article from last year on 4 Steps to Consolidating Multiple Operator Control Stations. Additionally, take a peek at Avid's guest blog post at Automation World for more.
What do you think? Has virtualization been a good thing for process control? Does virtualizing a system help make it more secure, or less?
