Most feature-rich service mesh. mTLS, traffic management, telemetry. High ops overhead.
Simpler and lighter than Istio. Rust data plane. Better choice unless you need Istio's full feature set.
Most widely deployed open-source API gateway.
The data plane under Istio. Used standalone as a sidecar or edge proxy.
Dominant event streaming backbone for event-driven microservices.
Simpler and lighter than Kafka. Better for request/reply patterns and lower-latency messaging.
Best open-source solution for distributed workflow orchestration and saga implementation.
CNCF distributed tracing. OpenTelemetry-compatible.
The instrumentation standard. Use this as your telemetry layer; backend is pluggable.
