When it comes to choosing a container management platform, you’re spoiled for choice these days. If you want an out-of-the-box multi-tenant platform that supports both Linux and Windows, though, you don’t quite have as many options.

ContainerX, which is launching out of beta today, supports both Docker and Windows Containers (still experimental for now, as Microsoft hasn’t released the final version of Windows Server 2016 yet), as well as private and public cloud solutions.

ContainerX CEO and co-founder Kiran Kamity tells me that at least a third of the companies that reached out to his company during the beta were specifically interested in its products because they want to move their legacy .NET applications to a container platform. Another third was mostly interested in the platform’s multi-tenancy support, and the rest were looking for a turn-key container management service.

It’s no surprise Kamity is interested in the Windows market for containers. His first startup, RingCube, brought containers to Windows long before anybody talked about Docker (RingCube was later acquired by Citrix).

Kamity noted that there are lots of table stakes when it comes to container management solutions. Windows support is one way for ContainerX to differentiate itself from the competition. Another is the company’s solid integration with VMware’s tools (partly driven by the fact that some of the team members previously worked for VMware) and ContainerX’s elastic cluster and container pools. While most container management services can obviously scale up and down as needed, ContainerX argues that its implementation provides enterprises with a more resilient service that is also able to more effectively isolate different users from each other.

One of ContainerX’s first service provider clients is Advantage24, which runs several data centers in Tokyo.

“We have evaluated most of the container management platforms out there, over the course of the last eighteen months and, after quite a bit of research, chose ContainerX,” said Terry Warren, President and co-founder of Advantage24. “Their multi-tenancy features such as Container Pools, support for bare-metal platforms as a first-class citizen, coupled with their turnkey user experience, makes them ideal for any enterprise or service provider looking for a complete container management solution.”

Now that ContainerX is out of beta, the service offers three pricing tiers: there is a free tier with support for up to 100 logical cores, as well as a gold plan that starts at $25,000 per year for small and medium enterprises and a high-end plan for large enterprises and service providers that starts at $75,000 and includes support for chargebacks, among other things.
