Linkerd is a Kubernetes-native service mesh that provides secure, reliable, and observable service-to-service communication without requiring application code changes. It is commonly used by platform and DevOps teams operating microservices on Kubernetes to reduce networking complexity, improve traffic resilience, and standardize service identity and encryption across clusters.
Linkerd is typically installed per cluster and injects lightweight proxies alongside workloads, enabling consistent policy and telemetry for east–west traffic. It is often evaluated alongside other meshes such as Istio when teams need mTLS, traffic control, and operational visibility while keeping the application layer unchanged.
Service mesh technology is a networking layer that facilitates communication between services in a distributed system. It simplifies the task of managing the underlying network infrastructure, allowing developers to focus on building and deploying applications without worrying about the complexities of network management. Service mesh also provides advanced security features such as traffic monitoring and encryption, ensuring the system is resilient and safeguarded against malicious attacks.
Here are some reasons to use tools in the service mesh category:
Linkerd is a lightweight, Kubernetes-native service mesh used to add secure, observable, and reliable service-to-service communication without requiring application code changes. It is commonly adopted to standardize traffic management and security controls across microservices.
Linkerd is often a strong fit for teams that want core service mesh capabilities with minimal complexity. Trade-offs can include fewer advanced L7 routing features than heavier meshes, and the sidecar model still adds per-pod resource overhead that should be budgeted and monitored.
Common alternatives include Istio, Consul, and Kuma. For service mesh fundamentals and deployment patterns, see the upstream documentation at https://linkerd.io/.
Our experience with Linkerd helped us build repeatable rollout patterns, operational runbooks, and automation that let clients secure and observe Kubernetes service-to-service traffic while keeping performance predictable and day-2 operations practical.
Some of the things we did include:
This experience helped us accumulate significant knowledge across Linkerd use-cases—from first-time mesh adoption to mature, observable, and secure operations—and enables us to deliver high-quality Linkerd setups that are reliable to run and straightforward to evolve.
