In this chapter, we understood the overall architecture of BookInfo and how to install the application through a simple deployment of its YAML file on Kubernetes. We also learned how to check BookInfo's availability for pods, services, and deployments and validated its service-based IP address for all six services. Now that we have installed the demo application, we will be able to understand Istio's different service mesh capabilities.
In the next chapter, we will jump straight into the installation of Istio's service mesh and share best practices around how each install process works. Thereafter, we will use the BookInfo application we have just installed to explain Istio's service mesh capabilities, such as traffic management, security, telemetry, and overall observability.
