Software ecosystems are becoming increasingly complex and fragmented, making it difficult for organizations to manage the thousands of interdependencies within their environments. To address this issue, Datadog has introduced Service Catalog schema v3.0 in private beta, which provides teams with an improved framework for modeling their software environments. The new version allows users to manually supplement and override automatically derived data, define a range of entity types, map relationships, and specify multi-ownership. Additionally, the IDE plugin helps developers create and validate their entity definitions, while Software Templates automate new entity setup. These enhancements enable teams to gain a clearer view of their tech stacks, improve collaboration during incidents, and more easily communicate architecture knowledge to new team members.
