Servers are expensive. And in single-application installations, most servers spend the majority of their time waiting. Making the most of these expensive assets led to virtualization, and making the most of virtualization has led to multiple options for virtualizing applications.

<a href="https://www.vmware.com/">VMware</a> and <a href="https://www.docker.com/">Docker</a> offer competing methods for virtualizing applications. Both technologies work to make the most of limited hardware resources, but they do so in significantly different ways. This post will help you understand how they differ and how those differences affect which scenarios each is best suited for. In particular, we’ll take a brief look at how each works, what the differences mean for the application and the deploying team, and how those differences can have an impact on operations, security, and application performance.

This article on VMware vs Docker is aimed at both IT operations and application development leaders who want to expand the options in their deployment toolkit. The information will help those leaders make more informed decisions and explain those decisions to colleagues and executives.

VMware is a company with a wide variety of products, from those that virtualize a single application to those that manage entire data centers or clouds. In this article, we use “VMware” to refer to VMware vSphere, used to virtualize entire operating systems; many different operating systems, from various Linux distributions to Windows Server can be virtualized on a single physical server.

VMware is a type-1 hypervisor, meaning it sits between the virtualized operating system and the server hardware; a number of different operating systems can run on a single VMware installation, with OS-specific applications running on each OS instance.

Docker is a system for orchestrating, or managing, application containers. An application container virtualizes an application and the software libraries, services, and operating system components required to run it. All of the Docker containers in a deployment will run on a single operating system because they’ll share commonly used resources from that operating system. Sharing the resources means that the application container is much smaller than the full virtualized operating system created in VMware. That smaller software image in a container can typically be created much more quickly than the VMware operating system image — on the scale of seconds rather than minutes.

The key question for the deployment team deciding on VMware vs Docker is why virtualization is being considered in the first place. If the point of the shift is at the operating system level — to provide each user or user population with its own operating environment while requiring as few physical servers as possible — then VMware is the logical choice. If the focus is on the application, with the operating system hidden or irrelevant to the user, then Docker containers become a realistic option for deployment. PostVer 0
