Cloud Load Balancers
Configure cloud-native load balancers (e.g., GCP, AWS, Azure) to handle gRPC traffic efficiently.
Cloud Load Balancers for gRPC
When deploying gRPC services in the cloud, efficient traffic distribution is crucial. Cloud Load Balancers manage incoming requests, directing them to healthy service instances.
However, gRPC's reliance on HTTP/2 and long-lived connections introduces unique considerations that traditional load balancers designed for HTTP/1.1 might struggle with.
gRPC and HTTP/2 Basics
Recall that gRPC leverages HTTP/2 for its transport layer. Key HTTP/2 features include:
- Multiplexing: Multiple logical streams over a single TCP connection.
- Header Compression: Reduces overhead.
- Server Push: (Less common for gRPC, but a feature).
These features enable high performance but also change how load balancers need to operate.
