# Scale Up Your Enterprise With Docker Subdomain Routing

Docker is an open source platform that came to life in 2014 and was recently rated the most loved/wanted tool by developers, according to a [survey](https://survey.stackoverflow.co/2022/#technology-most-popular-technologies). But it's not just developer preference. In the last two years, the percentage of enterprises with more than half of their containers in production has increased by 32%.

As teams expand their use of Docker for more and higher priority workloads, managing a growing list of hosts becomes a daunting task.

## Efficiency and Scalability for the Masses

To improve ease of use and administration, [Sonatype Nexus Repository](/content/products/sonatype-nexus-repository/index.html) has added subdomain connectors for Docker users. Where normally unique Docker instances are given a separate port number, now they have a standard name.

By default, listings like the one below must be shared, remembered, and referenced:

|     |     |
| --- | --- |
| nexus.example.com:1996 | Jenkins |
| nexus.example.com:1997 | Roman |
| nexus.example.com:1998 | Fileserv |

Developers and system administrators alike know how difficult the various port numbers can be difficult to track and maintain. Instead, what if you could make them easy-to-remember named addresses?

|     |
| --- |
| Jenkins.nexus.example.com |
| Roman.nexus.example.com |
| Fileserv.nexus.example.com |

Other benefits include:

- Improved scalability for more Docker repositories.
- Avoid misconfiguration risks and delays.
- Avoid modifying config files every time you add a new Docker instance, as with a "[reverse proxy](https://help.sonatype.com/en/docker-repository-reverse-proxy-strategies.html)" setup.
