Remember the good old days when we managed servers as large, bulky, beige-colored boxes that looked, smelled, and sounded like servers? OK, maybe saying “good old days” is a stretch, but either way, life was pretty straightforward.
Today, we can find servers – or the “compute layer” – in just about every size and shape imaginable, and even virtualized within a physical compute node.
And now, after everyone finally managed to wrap their noodles around that, we’re going to further slice up workloads into even smaller chunks called containers!? What?!
In this show, we get the skinny on just what the heck containers mean for the modern data center from some snazzy experts on the topic. Our guests are Brent Salisbury, a longtime networking guy who now works at Docker; and Nigel Poulton, a technology evangelist and cohost of the In Tech We Trust podcast.
We talk about exactly what a container is, how it differs from hypervisors and virtual machines and how containers and VMs can work together. We also talk about the kinds of workloads that make sense for containers, the various container projects in the works, and how containers cross operational silos.

Part 1: Introduction To Containers
- What exactly is a container – a specific software distribution, service, or a concept?
- Are containers a new idea, or an expansion on an old technique with a modern twist?
- Why are container so popular today – did something change in the hardware or software world that made them attractive?
- We’ve already spent a fair amount of effort virtualizing workloads onto hypervisors – can you contrast a virtual machine with a container? Can VMs and containers co-exist?
- What are some projects in the container ecosystem that are popular today?
Part 2: Containers In The Real World
- Can you describe some workloads/applications that best benefit from being containerized?
- What about workloads that wouldn’t be a good fit for a container model?
- Do you need to run containers within a cloud provider, or do they also make sense to use in your data center?
- What sort of changes are required for an IT department to begin leveraging, or at least supporting, the use of containers for their customers and business units?
- Lifecycle management – how do you manage a deluge of containers versus a smaller, and likely more static, quantity of virtual machines?
- What is Docker Hub and how do enterprises take advantage of it?
Part 3: Learning Containers/Silo Busting
- Who should be learning more about containers – developers, IT professionals, SMEs, or some mixture of them all?
- What resources are available to those new to containers?
- Nigel’s Pluralsight Course
- Why did you decide to make this course, and what can people expect from it?
- Can I use private or hosted lab to tinker around with containers – and if so, what sort of equipment would make sense?
- If I want to introduce containers into my data center, how can I best help crush IT Silos to get the team on board?
- Is this something that only DevOps shops can really grab hold of?
- What challenges have you faced getting the various SMEs to engage on container technologies?
