To perform traffic load balancing in east-west traffic control (internal communication between services within a data center or cloud environment), you can use the following approaches:
Service Mesh: Implement a service mesh like Istio or Linkerd to manage traffic routing, load balancing, and observability between microservices. These tools provide fine-grained control over east-west traffic, including retries, circuit breaking, and load distribution.
Load Balancers (L4/L7): Deploy internal load balancers (Layer 4 or Layer 7) to distribute traffic across backend services. For example, a Layer 7 load balancer can route requests based on HTTP headers or URLs, while a Layer 4 load balancer distributes traffic based on IP and port.
DNS-Based Load Balancing: Use internal DNS services to resolve service names to multiple IP addresses, enabling round-robin or weighted load distribution.
Traffic Shaping & Policies: Apply policies to prioritize or throttle traffic between services, ensuring critical workloads receive sufficient bandwidth.
Example: In a microservices architecture, Service A communicates with Service B and C. By deploying Istio, you can configure virtual services and destination rules to balance traffic between B and C, apply retries on failures, and monitor latency.
For cloud-based implementations, Tencent Cloud offers Tencent Service Mesh (TSM) for managing east-west traffic, along with Load Balancer (CLB) for distributing internal traffic efficiently. These services integrate seamlessly with Kubernetes and virtual machines, ensuring high availability and scalability.
