How to control outbound traffic with Istio ServiceEntries and Egress Gateways for compliance and auditing.
What you'll learn
- ServiceEntry = register external service in the mesh
- Egress Gateway = controlled, audited outbound traffic
- Apply VirtualService + DestinationRule to external services
ServiceEntry Overview
ServiceEntry registers external services (outside the mesh) so Istio can apply traffic management. Example: register api.stripe.com as a ServiceEntry, then create a VirtualService to add retries and timeout. Egress Gateway: channel all outbound traffic through a dedicated proxy for auditing, rate limiting, and TLS origination.
Key takeaways
