| Purpose | AWS X-Ray collects data about application requests and provides tools to view, filter, and analyze it to identify issues and optimization opportunities. | Jaeger is an open-source distributed tracing platform for monitoring and troubleshooting workflows in complex distributed systems. |
| Sampling | The X-Ray SDK samples requests, with a default of the first request each second and five percent of additional requests; sampling rules can be configured. | Jaeger supports head-based sampling with centralized remote configuration, including static or adaptive configuration, and tail-based sampling. |

In their own words
AWS X-Ray
AWS X-Ray is a cloud service for collecting and examining application request traces. A trace can show request and response details alongside calls to downstream AWS resources, microservices, databases and web APIs. X-Ray also uses trace data to map clients, front-end services and backend services, helping identify bottlenecks and latency spikes.
Applications can send traces through X-Ray SDKs or APIs, AWS Distro for OpenTelemetry, or CloudWatch Application Signals. AWS integrations can add tracing headers, transmit data, run the daemon or instrument requests. For Lambda, the daemon can record invocation details, while the SDK can trace outgoing calls and add annotations and metadata. The SDK samples requests by default, with configurable sampling rules. Trace data is retained for 30 days and encrypted at rest; AWS Identity and Access Management controls access. X-Ray has a free allowance of 100,000 traces recorded and the first 1,000,000 traces retrieved or scanned per month; additional usage is billed by usage. Beginning February 25, 2026, AWS limits X-Ray SDK and daemon releases to security fixes and recommends migration to OpenTelemetry.
Jaeger
Jaeger is a free, open-source distributed tracing platform for monitoring complex systems and investigating performance problems. It helps teams locate bottlenecks, examine root causes, and map dependencies between services. Jaeger receives OpenTelemetry Protocol data and accepts Zipkin spans over HTTP in Thrift, JSON v1/v2, and Protobuf formats. Its UI includes System Architecture and Deep Dependency Graph views, while Service Performance Monitoring turns traces into aggregate metrics and time-series charts. Sampling supports head-based configurations, including centralized static or adaptive settings, and tail-based sampling. Cassandra, Elasticsearch, and OpenSearch are supported distributed storage backends; ClickHouse is experimental behind a feature gate. Jaeger v2 ships as binaries and container images, with an all-in-one mode using transient in-memory storage. It is self-hosted, so infrastructure determines capacity and scale. Jaeger v1 reached end of life on December 31, 2025.
