How Does Tetrate Service Bridge Help Optimize Locality and Minimize Egress?

Tetrate Service Bridge (TSB) takes advantage of built-in tools like Envoy’s locality-aware and locality-prioritized load balancing combined with TSB’s high-level understanding of your topology to ensure traffic flows as efficiently as possible – staying within the local region or availability zone as much as is possible, taking into account explicit traffic shifting and failover for high-availability and disaster recovery.

Locality-Aware Load Balancing

TSB leverages Envoy’s locality-aware load balancing capabilities to route traffic to the closest available service instances. This approach:

Reduces Latency: Traffic stays within the same region or availability zone when possible
Minimizes Cross-Region Costs: Reduces data transfer costs between regions
Improves Performance: Faster response times for end users
Maintains Availability: Automatically fails over to other regions when needed

Topology Understanding

TSB’s high-level understanding of your infrastructure topology enables:

Intelligent Routing: Routes traffic based on geographic proximity and service availability
Automatic Failover: Seamlessly shifts traffic to healthy regions during outages
Load Distribution: Balances traffic across multiple regions for optimal performance
Cost Optimization: Minimizes unnecessary cross-region traffic

Traffic Management Features

TSB provides advanced traffic management capabilities including:

Locality-Prioritized Load Balancing: Prioritizes local instances while maintaining global availability
Traffic Shifting: Explicit control over traffic distribution across regions
Disaster Recovery: Automatic failover mechanisms for high availability
Performance Monitoring: Real-time visibility into traffic patterns and performance
