Effective access management is crucial for maintaining security and efficiency in your ZenML projects. This guide will help you understand the different roles within a ZenML server and how to manage access for your team members.
In an ML project, you will typically have the following roles:
Data Scientists: Primarily work on developing and running pipelines.
MLOps Platform Engineers: Manage the infrastructure and stack components.
Project Owners: Oversee the entire ZenML deployment and manage user access.
The above is an estimation of roles that you might have in your team. In your case, the names might be different or there might be more roles, but you can relate the responbilities we discuss in this document to your own project loosely.
Service connectors are how different cloud services are integrated with ZenML. They are used to abstract away the credentials and other configurations needed to access these services.
Ideally, you would want that only the MLOps Platform Engineers have access for creating and managing connectors. This is because they are closest to your infrastructure and can make informed decisions about what authentication mechanisms to use and more.
Other team members can use connectors to create stack components that talk to the external services but should not have to worry about setting them and shouldn't have access to the credentials used to configure them.
Let's look at an example of how this works in practice.
Imagine you have a DataScientist role in your ZenML server. This role should only be able to use the connectors to create stack components and run pipelines. They shouldn't have access to the credentials used to configure these connectors. Therefore, the permissions for this role could look like the following:
You can notice that the role doesn't grant the data scientist permissions to create, update, or delete connectors, or read their secret values.
On the other hand, the MLOpsPlatformEngineer role has the permissions to create, update, and delete connectors, as well as read their secret values. The permissions for this role could look like the following:
The decision to upgrade your ZenML server is usually taken by your Project Owners after consulting with all the teams using the server. This is because there might be teams with conflicting requirements and moving to a new version of ZenML (that might come with upgrades to certain libraries) can break code for some users.
Performing the upgrade itself is a task that typically falls on the MLOps Platform Engineers. They should:
ensure that all data is backed up before performing the upgrade
no service disruption or downtime happens during the upgrade
When you upgrade to a new version of ZenML, you might have to test if your code works as expected and if the syntax is up to date with what ZenML expects. Although we do our best to make new releases compatible with older versions, there might be some breaking changes that you might have to address.
The pipeline code itself is typically owned by the Data Scientist, but the Platform Engineer is responsible for making sure that new changes can be tested in a safe environment without impacting existing workflows. This involves setting up a new server and doing a staged upgrade and other strategies.
Apart from the role-specific tasks we discussed so far, there are some general best practices you should follow to ensure a secure and well-managed ZenML environment that supports collaboration while maintaining proper access controls.
Regular Audits: Conduct periodic reviews of user access and permissions.
Role-Based Access Control (RBAC): Implement RBAC to streamline permission management.
Least Privilege: Grant minimal necessary permissions to each role.
Documentation: Maintain clear documentation of roles, responsibilities, and access policies.
By following these guidelines, you can ensure a secure and well-managed ZenML environment that supports collaboration while maintaining proper access controls.
Note that you can only use the RBAC features in ZenML Pro. Learn more about roles in ZenML Pro .

You can choose to have different servers for different teams and that can alleviate some of the pressure to upgrade if you have multiple teams using the same server. ZenML Pro offers out of the box, for situations like these. Sign up for a free trial to try it yourself: https://cloud.zenml.io/
and more. Read in detail about the best practices for upgrading your ZenML server in the guide.
The Data Scientist should also check out the release notes, and the migration guide where applicable when upgrading the code. Read more about the best practices for upgrading your ZenML server and your code in the guide.
