# AWS OpenTelemetry Operator
|
||||
|
||||
[AWS Distro for OpenTelemetry (ADOT)](https://aws-otel.github.io/) is a secure,
|
||||
production-ready, AWS-supported distribution of the OpenTelemetry project.
|
||||
Part of the Cloud Native Computing Foundation, OpenTelemetry provides open
|
||||
source APIs, libraries, and agents to collect distributed traces and metrics
|
||||
for application monitoring.
|
||||
|
||||
This modules deploys either the
|
||||
[AWS Managed ADOT OpenTelemetry Operator for EKS](https://aws.amazon.com/about-aws/whats-new/2022/04/eks-opentelemetry-operator-now-available/)
|
||||
or [the OpenTelemetry Operator](https://github.com/open-telemetry/opentelemetry-helm-charts)
|
||||
through helm.
|
||||
The OpenTelemetry Operator is an implementation of a Kubernetes Operator.
|
||||
A Kubernetes Operator is a method of packaging, deploying and managing a
|
||||
Kubernetes-native application, which is both deployed on Kubernetes and
|
||||
managed using the Kubernetes APIs and kubectl tooling. The Kubernetes Operator
|
||||
is a custom controller, which introduces new object types through Custom Resource
|
||||
Definition (CRD), an extension mechanism in Kubernetes.
|
||||
In this case, the CRD that is managed by the OpenTelemetry Operator is the Collector.
|
||||
|
||||
> :warning: We do install [cert-manager](https://cert-manager.io/) as a [hard requirement](https://docs.aws.amazon.com/eks/latest/userguide/opentelemetry.html) for
|
||||
the ADOT Operator.
