Multi-Cluster Deployment Patterns for Ingress and API Gateways

In this webinar, we will explore deployment patterns, configurations, global traffic routing policies and more for scalable, highly available, and resilient application environments using Envoy Proxy for the Edge / API Gateway across multiple clusters. We will compare the tradeoffs between the different patterns for consideration and guidance for implementation and operations.

14. 14 | Copyright © 2020 Problems Solo.io solves with federation • Security (authz/authn/encryption/identity) • Service discovery • Failover / traffic shifting / transparent routing • Observability • Separate networks • Well-defined fault domains • Balance of centralized management with decentralized enforcement

16. 16 | Copyright © 2020 Why Envoy Proxy? • Neutral Foundation (CNCF) • Large, diverse, vibrant community • Built ground up for dynamic services environment • Dynamic configuration, driven by API • Highly extensible • L7 filters (HTTP/1, HTTP/2, gRPC, redis, mysql, Kafka, etc) • Deep metrics/telemetry out of the box • Versatile deployment options
