What is still needed in the Julia ecosystem to make a good data science microservice in Julia?

Julia is a language with a focus on the data science ecosystem. However, integrating Julia into existing ecosystem can be challenging. Targeting data science microservice can be a good way to increase Julia use and allow for gradual adoption of Julia. What are the major improvements needed to make Julia excellent at data science microservice?

For example, Julia package can be a good way to exactly specify the environment. Do we have a good way to deploy such a package on docker? What’s still needed?

Do you have a particular use-case in mind? Are you trying to build a data science microservice?

Because without a concrete goal, this kind of discussion is probably not going to be fruitful.
