Does it matter what virtualization technology you use? Richard chats with Greg Shields, one of the few folks out there with certifications in Microsoft's Hyper-V, VMWare's vSphere and Citrix Xen about the relatively merits of the stacks. Turns out, they're pretty close together, at least when it comes to virtualization. But the conversation goes deeper into the instrumentation - how do you know that you have the right loads on the right hardware? Can you make your own cloud effectively - it's got more to do with architecture than operating systems, as it turns out. Greg focuses in on the way you understand your systems as the true differentiator today!

What does your security plan look like? Richard chats with Dana Epp about the ever increasing attack surface of our organizations and the ongoing battle to provide better tools and techniques to keep the lights on. Hackers are getting more clever, even hacking cars - how do you keep up? Dana talks through a series of policy approaches to deal with the reality that you are going to be breached, but how to you detect the breach and limit the damage caused? Check out Dana's article on credential theft for even more ideas!

There are lots of reasons to instrument your apps in production - but one of the most powerful is to understand how your users actually use your apps. Richard talks to Andreas Grabner of DynaTrace about the variety of instrumentation approaches possible for applications - some driven by operations, and some by development. But everyone in the organization can benefit from a deeper understanding of how applications are used. Andreas talks about the diversity of metrics that can be taken, from your typical ecommerce financial metrics, to performance metrics, to reliability and scalability. There's a lot to measure!

Well, that's it - ARIN is out of IPv4 addresses. Richard chats with Ed Horley who has been warning of this day for a number of years now. So what does it really mean? No, the internet isn't going to stop working. Ed talks about how much IPv6 is already going on - some ISPs have double-digit adoption already! And certain marketplaces need it the most, such as smartphones. There are billions of smartphones, and the Internet of Things looks to bring many more billions of devices online as well... we need IPv6! The time is now!

Windows 10 has shipped - but has it really, really shipped? Richard chats with Paul Thurrott about his take on Microsoft's on-going efforts to get the operating system just right. After some history discussion about how Windows 10 came to be, from Vista on up, Paul digs into the truth of the matter - Windows 10 isn't quite done yet, it's fine for consumers, but IT Pros need to look carefully. It's a powerful operating system that alongside the upcoming Server 2016 should be able to take infrastructure to the next level, which Paul says is hybrid cloud. But there's still more to come, so watch close!
