Blog



This article provides guidance on optimizing cost and performance for Elastic Load Balancer (ELB) in AWS. It covers best practices for achieving efficient connection management, high throughput, low latency, and reliable performance during peak demand periods.

Specifically, the article covers:

  • Optimizing client connections through connection pooling, tuning idle timeouts, and using TLS 1.3 and session reuse
  • Optimizing inbound and outbound traffic by compressing payloads, using efficient data serialization protocols, caching content at the edge, and avoiding unnecessary data transfers
  • Considerations for enabling Cross-Zone Load Balancing (CZLB) and its impact on data transfer costs and client IP preservation
  • Good housekeeping practices like consolidating ELBs, monitoring service behavior, and removing unused ELBs
  • Conclusion emphasizing the importance of optimizing ELB setup based on workload characteristics for cost, performance, and latency benefits
