About Linkerd Essentials Exam
Linkerd is a lightweight and highly efficient service mesh designed for Kubernetes environments. It enhances security, observability, and reliability in microservices architecture by automatically managing service-to-service communication. Unlike other service meshes, Linkerd is simple to use, lightweight, and built with performance in mind. Linkerd functions by deploying transparent proxies next to each service instance, handling all incoming and outgoing traffic. These proxies collect telemetry data, optimize network communication, and improve application reliability. Because Linkerd is fully open source and CNCF-hosted, it is a great choice for DevOps teams working with cloud-native applications.
Key Highlights
This course will teach you how to configure and deploy Linkerd, install its CLI manually, inject it into applications, and use Flagger for progressive delivery. By the end of the course, you will have a solid understanding of how Linkerd works and how to integrate it into Kubernetes clusters for improved traffic management and monitoring.
