Deploying internal services using Knative serving
Demonstrates how to expose services deployed to Knative serving on your internal network. This type of configuration allows other resources in your network to communicate with the service using a private, internal (RFC 1918) IP address. Exposing services on an internal network is useful for enterprises that provide internal apps to their staff, and for services that are used by clients that run outside the Knative serving cluster.

Patterns for scalable and resilient apps
Learn patterns and practices for creating apps that are resilient and scalable, two essential goals of many modern architecture exercises. A well-designed app scales up and down as demand increases and decreases, and is resilient enough to withstand service disruptions. Building and operating apps that meet these requirements requires careful planning and design.
Scalability
Resilience
High availability
Use case
Use cases
Learn how to authenticate end users of applications deployed to Knative serving using Istio authentication policies and Identity Platform. Using Istio to authenticate means that authentication logic doesn't need to be part of the application code. This separation lets different teams be responsible for application code and authentication policy, and authentication policies can apply across multiple applications or services.
