Self-Service Domain-Specific Language (DSL)is the specific capability within Nutanix Self-Service (formerly Calm) that enablesInfrastructure-as-Code (IaC).
* Definition:The Self-Service DSL is a Python-based domain-specific language that allows administrators and developers to define Blueprints, Runbooks, and Projects as code.
* Functionality:Instead of using the Graphical User Interface (GUI), users can write Python code to describe the application structure, services, and logic. This code can then be version-controlled (e.g., in Git), reviewed, and deployed via the CLI, fulfilling the principles of Infrastructure-as-Code.
* Contrast:While "Application Development" and "Orchestration" are broad concepts, theDSLis the specific tool/feature that delivers the IaC mechanism.
