The Top 6 Questions You Asked on Containerizing Production Apps

We recently hosted IDC research manager Gary Chen as a guest speaker on a webinar where he shared results from a recent IDC survey on container and container platform adoption in the enterprise. IDC data shows that more organizations are deploying applications into production using containers, driving the need for container platforms like Docker Enterprise that integrate broad management capabilities including orchestration, security and access controls. The audience asked a lot of great questions about both the IDC data and containerizing production applications. We picked the top questions from the webinar and recapped them here. If you missed the webinar, you can watch the webinar on-demand here. Top Questions from the Webinar Q: What are the IDC stats based on? A: IDC ran a survey of 300+ container deployers from companies with more than 1,000 employees and have primary responsibility for Continue reading…

Are Containers Replacing Virtual Machines?

With 20,000 partners and attendees converging at VMworld in Las Vegas this week, we often get asked if containers are replacing virtual machines (VMs). Many of our Docker Enterprise customers do run their containers on virtualized infrastructure while others run it on bare metal. Docker provides IT and operators choice on where to run their applications – in a virtual machine, on bare metal, or in the cloud. In this blog we’ll provide a few thoughts on the relationship between VMs and containers.  Point #1: Containers Are More Agile than VMs At this stage of container maturity, there is very little doubt that containers give both developers and operators more agility. Containers deploy quickly, deliver immutable infrastructure and solve the age-old “works on my machine” problem. They also replace the traditional patching process, allowing organizations to respond to issues faster and Continue reading…

Containerd, BuildKit and a Reflection about the Enduring Value of Docker Engine

Two weeks ago was our eighth DockerCon in just four years. Our community of contributors, developers, IT users, enterprises and ecosystem partners has grown exponentially into the millions,  anchored on our founder Solomon Hykes’ simple premise of democratizing the use of the software container. Today as was from the beginning, Docker creates simple tooling and a universal packaging approach that bundles up all application dependencies inside the container.  Docker Engine enables applications to run anywhere consistently on any infrastructure, solving “dependency hell” for developers and operations teams, and eliminating the “it works on my laptop!” problem. In the past 2 years, Docker Engine’s codebase has been refactored into several reusable components, the most important being containerd, the core container runtime, and BuildKit, the part of Docker Engine used to build images. In the contribute and collaborate track at DockerCon, Michael Continue reading…

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…
