Guance 
Customer context
ComfortDelGro (CDG) is a Singapore-headquartered transport company. Its published Guance story describes digital services that require investigation across applications, cloud resources, logs, and third-party monitoring data.
The story also states that CDG previously used Datadog and reassessed data onboarding, deployment location, and the migration path for existing trace data as the monitoring scope expanded.
Business-system coverage used separate entry points
Applications and functions followed different monitoring paths, making it hard to move continuously from a business symptom to application, resource, and log evidence.
Data-transfer boundaries needed to be explicit
A cross-region business needed clear control over collection, transfer, storage location, and access rather than relying only on a default hosted path.
Implementation
Establish a full-stack platform with deployment choice
The published story describes unified onboarding for end-to-end traces, cloud resources, logs, and third-party monitoring data, with the data path managed in the customer-selected environment.
Ingest existing DDTrace data
Guance ingestion of Datadog DDTrace data allowed the team to reuse existing trace signals. Version, sampling, and dependency compatibility still require validation during migration.
Organise observability by operating region
Business systems and the observability platform could be placed in planned regions with explicit data-boundary, network-path, and access-policy decisions.
What changed
More signals entered one investigation path
Development, test, and operations teams could share application-trace, log, cloud-resource, and third-party context.
Existing tracing investment could move in stages
DDTrace ingestion reduced the need to rebuild every tracing entry point at once and left room for phased verification.
The data path became an architecture decision
Deployment region, storage environment, and access controls could enter the company’s governance review; a customer story is not evidence of automatic compliance.
