Kubernetes Ingress API

Istio, Service Mesh, and Ingress API are important concepts in managing modern microservice-based architectures. Here’s a breakdown of each:

1. Istio

Istio is an open-source service mesh that helps manage microservices by providing tools for monitoring, securing, and controlling communication between services. It abstracts away the complexities of managing service-to-service communications, including load balancing, security (e.g., mutual TLS), traffic routing, and observability.

• Key Features:
• Traffic Management: Advanced routing, load balancing, and fault injection for services.
• Security: Mutual TLS (mTLS) for securing service-to-service communication.
• Policy Enforcement: Enforce policies for access control and rate limiting.
• Observability: Metrics, distributed tracing, and monitoring for each service interaction.

Istio accomplishes this through sidecar proxies (usually Envoy), which are automatically injected into each service pod in Kubernetes, intercepting all network traffic.

2. Service Mesh

A service mesh is a dedicated infrastructure layer designed to handle the communication between microservices in a distributed application. It provides service…
