Webinar: Containerization for the Virtualization Admin

If you’re a virtualization admin there’s a good chance that the word “container” has floated by in the last few months. This is because enterprises of all sizes are now looking to leverage the power of containerization. But what is containerization and how can you leverage containers while also making use of your investment in virtualization?

Docker and HPE: Accelerating modern app architectures in enterprise datacenters

Docker has evolved tremendously over the last 3 years to empower developers and IT operations teams to maintain greater control over their own environments without sacrificing agility. From an ops tool used by the original dotCloud team, to Docker’s commercially supported Containers-as-a-Service (CaaS) platform, Docker Datacenter (DDC), Docker has been at the forefront of this evolution. Today we are excited to announce the next evolution in the Docker story providing enterprises with infrastructure optimized for the Docker platform with the leading provider of cloud infrastructure – Hewlett Packard Enterprise (HPE). Together, Docker and HPE will deliver integrated and fully supported Docker ready HPE x86 servers, bundled with Docker’s commercially supported Engine (CS Engine) right out of the box.

So, when do you use a Container or VM?

Recently I was giving a talk at a trade show on the basics of Docker, and how an application goes from an idea to being a production workload running on a Universal Control Plane managed Swarm cluster. As part of that talk, I spent a bit of time talking about how containers are not VMs. This was especially relevant as most of the attendees currently worked as virtualization sysadmins. During the QA portion of the session one of the attendees asked me “When does my application go in a VM and when does it go in a container?”

To Use Physical Or To Use Virtual: That is the container deployment question

I have had a version of the following conversation more than a few times with community members trying to sort out where to run their containerized apps in production: User: So, where should I run my containers? Bare metal or VM’s Me: It’s not a question of “either / or” – that’s the beauty of Docker. That choice is based solely on what’s right for your application and business goals – physical or virtual, cloud or on premise. Mix and match as your application and business needs dictate (and change). User: But, surely you have a recommendation. Me: I’m going to give you the two word answer that nobody likes: It depends. User: You’re right, I don’t like that answer. Me: I kind of figured you wouldn’t, but it really is the right answer. There are tough questions in the Continue reading…

Containers and VMs Together

A couple weeks back I talked about how Docker containers were not virtual machines (VMs). I received a lot of positive feedback on the article (thanks!), but I also heard a common question: Can VMs and Docker containers coexist? The answer is a resounding “yes.”

Containers are not VMs

I spend a good portion of my time at Docker talking to community members with varying degrees of familiarity with Docker and I sense a common theme: people’s natural response when first working with Docker is to try and frame it in terms of virtual machines. I can’t count the number of times I have heard Docker containers described as “lightweight VMs”. I get it because I did the exact same thing when I first started working with Docker. It’s easy to connect those dots as both technologies share some characteristics. Both are designed to provide an isolated environment in which to run an application. Additionally, in both cases that environment is represented as a binary artifact that can be moved between hosts. There may be other similarities, but to me these are the two biggies.
