1. Deis: Deis is an open source PaaS that focuses on simplicity and flexibility. It provides a platform for building and hosting applications on any infrastructure, whether it be on-premise or in the cloud. Deis offers a minimalistic approach, allowing developers to deploy and scale applications quickly without unnecessary complexity.

2. Deis Workflow: Deis Workflow is an enterprise-grade PaaS built on top of the Deis platform. It includes additional features and functionality that make it suitable for larger organizations and more complex deployments. Workflow provides built-in support for multi-tenant environments, giving teams the ability to isolate and manage their applications more effectively.

3. Scaling: Deis Workflow offers more advanced scaling capabilities compared to Deis. Workflow provides horizontal scaling, allowing applications to be scaled out by adding more instances. On the other hand, Deis only supports vertical scaling, which involves increasing the resources allocated to each instance.

4. Logging and Monitoring: Workflow includes built-in support for logging and monitoring, making it easier to debug and troubleshoot applications. It provides integrations with popular logging and monitoring tools, allowing developers and operations teams to easily access and analyze application logs and metrics. Deis, on the other hand, does not have built-in logging and monitoring capabilities and requires additional setup.

5. Team Management: Deis Workflow includes advanced team management features that facilitate collaboration and access control. It allows organizations to define and manage teams, roles, and permissions, allowing different teams to have different levels of access and control over applications and environments. Deis, on the other hand, does not have native team management capabilities and requires additional configuration.

6. Governance and Compliance: Workflow includes functionality to help organizations meet governance and compliance requirements. It provides features such as audit logs and integration with identity providers, making it easier to track and manage user activity and ensure compliance with regulations. Deis does not have built-in governance and compliance features.

In Summary, Deis and Deis Workflow are two PaaS solutions with different target audiences and functionalities. Deis is a lightweight and flexible platform, while Deis Workflow offers additional features for larger organizations and complex deployments, such as advanced scaling, logging and monitoring, team management, and governance and compliance capabilities.
