On-Demand Link: https://www.nginx.com/resources/webinars/api-gateway-use-cases-for-kubernetes/ About the Webinar Two app modernization trends – APIs and Kubernetes – have reached a critical adoption point where many organizations are now seeking to deliver APIs using Kubernetes. As with the containerization of applications, this strategy requires organizations to figure out how to deliver APIs quickly and safely. For traditional applications, the solution is a load balancer or ADC which routes API requests from a client to the appropriate services – in other words, an API gateway. But with Kubernetes come different ways to deliver both apps and APIs, which have in turn spawned two new traffic management tools: the Ingress controller and service mesh. Organizations are left with the question “Which tool should I use to deliver API gateway functionality in Kubernetes?” In this webinar, we help you answer that question by looking at the unique needs of containerized APIs (and their owners), sharing common use cases that can be solved with Kubernetes tools, and discussing what you can do to modernize your APIs for the Kubernetes era.

What is an API Gateway?
A SET OF USE CASES FOR DELIVERING APIS
Provides a single, consistent
entry point for multiple APIs,
regardless of how they are
implemented or deployed at the
backend.
Can be a…
✓ Load balancer
✓ ADC
✓ Ingress controller
✓ Service mesh

Smaller learning curve since
YAML is familiar to K8s teams
YAML-friendly tools
easily fit into K8s workflows
What type of tool is best for K8s?A K8s-native tool.
WE SUGGEST YAML-BASED
Fewer tools reduces
unnecessary latency and costs
