Prompt
What should I use for API traffic management in a hybrid cloud setup?
Latest observation
For API traffic management in a hybrid cloud setup, the best choice is usually a cloud-native API gateway with hybrid support or a service mesh + gateway combination, depending on where your APIs live and what you need to control.
Good options by use case
1) API Gateway (most common choice)
Use this if you mainly need:
- Authentication / authorization
- Rate limiting and throttling
- Request/response transformation
- Routing to services across on-prem and cloud
- API analytics and developer portal features
Examples:
- Kong Gateway / Kong Konnect
- Apigee Hybrid
- Azure API Management
- AWS API Gateway + hybrid integration patterns
- NGINX Plus / F5 / Traefik Hub
Best when your main concern is external API traffic management.
2) Service Mesh + Ingress Gateway
Use this if you need:
- Fine-grained service-to-service traffic control
- mTLS encryption across environments
- Retry, timeout, circuit breaking
- Traffic splitting / canary deployments
- Observability across microservices
Examples:
- Istio
- Linkerd
- Consul
Best when you’re managing internal microservice traffic in both on-prem and cloud.
3) Hybrid API Management Platform
Use this if you want centralized control across both environments with governance, policy enforcement, and developer management.
Examples:
- Apigee Hybrid
- Kong with hybrid control plane
- MuleSoft Anypoint Platform
- IBM API Connect
Best when you need enterprise governance and one platform for both cloud and on-prem APIs.
Practical recommendation
If you’re asking broadly, I’d recommend:
- For public/external APIs: a hybrid-capable API gateway
- For internal microservice traffic: a service mesh
- For full hybrid enterprise control: a hybrid API management platform
A common architecture
- API Gateway at the edge
- Service mesh inside clusters
- Central policy/observability layer
- Private connectivity between on-prem and cloud (VPN, Direct Connect, ExpressRoute, Interconnect)
If you want a short answer
Use a hybrid-capable API gateway like Kong, Apigee Hybrid, or Azure API Management; add a service mesh like Istio if you also need internal service-to-service traffic control.
If you want, I can also recommend the best option based on your cloud provider, budget, and whether your APIs are public or internal.
