Chapter 14: Service Meshes and Serverless
This chapter discusses advanced Kubernetes patterns. First, it details the in-vogue service mesh pattern, where observability and service-to-service discovery are handled by a sidecar proxy, as well as a guide to setting up Istio, a popular service mesh. Lastly, it describes the serverless pattern and how it can be applied in Kubernetes. The major case study in this chapter will include setting up Istio for an example application and service discovery, along with Istio ingress gateways.
Let's start with a discussion of the sidecar proxy, which builds the foundation of service-to-service connectivity for service meshes.
In this chapter, we will cover the following topics:
- Using sidecar proxies
- Adding a service mesh to Kubernetes
- Implementing serverless on Kubernetes
