Where is my cache? Architectural patterns for caching microservices
Everybody knows that we need a cache, but where exactly to place it? Inside your application or as a layer in front of it? In the container or outside the container?

In this session I’ll present different architectural patterns for distributed caching: Embedded, Client-Server, (Kubernetes) Sidecar, and Reverse HTTP Proxy Caching. In this session you’ll learn: – What are the design options for including the caching layer – How to apply caching layer in Istio (and Service Mesh in general) – How to use distributed HTTP caching without updating your microservices – Common pitfalls when setting up caching for your system
