The Role of a
Service Mesh
13
What is a service mesh?
A service mesh is a dedicated infrastructure layer for making service-to-
service communication safe, fast, and reliable. If you’re building a cloud
native application, you need a service mesh!

Proxy Model
• Focus on internet traffic• A shock absorber for your app• Dynamic connectivity
MORE INFORMATION AT
NGINX.COM
Proxy Model
• Inbound traffic is
managed through a
reverse proxy/load
balancer
• Services are left to
themselves to connect to
each other.
• Often through round-robin
DNS

NGINX.COM
Router Mesh
• Robust service discovery
• Advanced load balancing
• Circuit breaker pattern
MORE INFORMATION AT
NGINX.COM
Router Mesh
Model
• Inbound routing through
reverse proxy
• Centralized load
balancing through a
separate load balancing
service
• Deis Router works like
this

Circuit
Breakers
• Active health checks
• Retry
MORE INFORMATION AT
NGINX.COM
Fabric Model
• Robust service discovery
• Advanced load balancing
• Circuit breaker pattern
• Persistent SSL network
MORE INFORMATION AT
NGINX.COM
Inter-Process
Communication
• Routing is done at the
container level
• Services connect to each
other as needed
• NGINX Plus acts as the
forward and reverse
proxy for all requests
MORE INFORMATION AT
NGINX.COM
Kubernetes Load Balancing• Implemented by Services as internal or external load
balancers
• Ingress and Ingress Controllers are more robust forms of
load balancing in Kubernetes
• The NGINX Ingress Controller provides all the load
balancing features NGINX within Kubernetes

Controller for
Kubernetes - Open source

Istio Load Balancing• In order to discover services Istio assumes the presence
of a service registry
• NGINX has built the nginxmesh repository which
provides an implementation of a sidecar proxy for Istio
using NGINX
