CPS launched in tech preview on April 16, 2026. This GA release ships with meaningful additions.

Scale: Support for up to 100 linked projects is included by default. Enterprise teams and MSSPs that link per-client or per-region projects can now operate at the scale their architectures require. Higher limits are available upon request.

Serverless project as an origin: At GA, existing projects can link and query across as many as 100 linked projects without requiring migration or recreation.

ML and AI capabilities: With CPS, Elastic ML jobs detect anomalies in time-series data unsupervised, and at GA they can query across multiple linked projects in a single job. Application performance monitoring (APM) anomaly detection in Elastic Observability can also span linked projects, giving SRE teams a unified anomaly view. Moreover, Elastic Agent Builder enables AI agents across all solutions to retrieve context from multiple linked serverless projects, establishing CPS as a foundational building block for production agents operating on distributed data.

Versionless and cloud-agnostic: Teams aren't locked into a single cloud vendor or forced to coordinate versions across deployments just to do a search. And it works across every solution: Observability, Security, Search, and vector database workloads.

Observability: Application and infrastructure monitoring, alerting, SLOs, and APM anomaly detection work across linked projects enabling flexible data locality and analysis.
Security: CPS powers the Central SOC model: Detection rules run once on a central project and query across every linked project, so SOC teams triage one alert without manually merging data or duplicating alert rules. Entity information and Elastic Defend telemetry from linked projects feed that same central view.
Search: ES|QL queries and Discover sessions span linked projects by default. Across all solutions at GA an AI agent can retrieve context from multiple linked projects in a single query, making CPS a foundational building block for production agents that operate across distributed data.

Complete access control: A user's access to data across linked projects is determined by their individual permissions on each project, not by where they're querying from. What that user can see is always complete and consistent with what they are authorized to see.

Reduced costs: Because data stays where it is, you pay for the queries you run, not for storing and moving the same bytes twice.

Full project routing: It gives teams precise control over which projects a query targets. Using predefined tags such as region, cloud provider, and project alias — or custom tags you define — you can route any query to a specific subset of linked projects. Named expressions and boolean logic (AND, OR, NOT) let you build reusable routing rules for common patterns, such as "all EU projects" or "all MSSP tenant environments except staging."

Programmatic CPS access: CPS has introduced a new user role that enables anyone, not just organization owners, to generate Cloud API keys for CPS queries, removing friction for teams building pipelines and applications on CPS.
