How do you keep a computer running non-stop? This week Technology Now explores the world of fault tolerant computing. We dive into how fault tolerance works, what industries use it, and why such a useful form of computing isn’t as ubiquitous as we might expect. Casey Taylor, Vice President and General Manager HPE Nonstop Compute tells us more.

This is Technology Now, a weekly show from Hewlett Packard Enterprise. Every week, hosts Michael Bird and Aubrey Lovell look at a story that's been making headlines, take a look at the technology behind it, and explain why it matters to organizations.
