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

MORE INFORMATION AT

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

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
