Can You Replace API Management with Service Mesh?

A commonly asked question is “can I replace the edge/API gateway or API management solution with a service mesh?” While the service mesh solves communication challenges between services in a cluster (east/west traffic), there still exists the need to manage the traffic entering and exiting a cluster (north/south traffic), and while complimentary, they are different traffic patterns. Additionally, not all applications are able to run in Kubernetes and service mesh or even as a container.

This Presentation Covers:
* Evolving traffic patterns from the edge/ingress to service mesh
* How the traffic patterns differ and areas for integration
* Envoy as the underlying proxy technology for the modern application network
* Key capabilities of Envoy based networks
* How to incrementally adopt and operationalize across multiple clusters

4. 4 | Copyright © 2020 As we move to services architectures, on cloud-native deployment platforms, we increase the complexity between our services.
5. 5 | Copyright © 2020 How we typically like to solve this problem:
6. 6 | Copyright © 2020 API Management • Expose APIs • Enforce usage policy/quota • Throttle/spike arrest/rate limit • Security AuthN/AuthZ • Self service / developer portal • Lifecycle management • Analytics / monetization • Abstraction / transformation
7. 7 | Copyright © 2020 Legacy API Management Challenges • Does not scale in cloud environments (static) • Typically implemented highly centralized • Bottleneck • Processes, no delegation • Automation • Built on legacy technology
8. 8 | Copyright © 2020 Enter the service mesh!

11. 11 | Copyright © 2020 Service mesh technologies provide the following: • Service discovery / Load balancing • Secure service-to-service communication • Traffic control / shaping / shifting • Policy / Intention based access control • Traffic metric collection • Service resilience • API / programmable interface
12. 12 | Copyright © 2020 Can you replace API management with service mesh? What’s missing? • Enforce usage policy/quota • Throttle/spike arrest/rate limit • End user security challenges (Oauth2 flows/OIDC/LDAP) • Edge security (WAF) • Self service / developer portal • Lifecycle management • Analytics / monetization • Abstraction / transformation
