## UDS

**Packet Transport**: Unix Domain Socket File

| Advantages | Disadvantages |
|-------------------------------------------------------|------------------------------------------------------------------------------------------------------|
| No IP or DNS resolution requirement for Datadog Agent | Requires [hostPath](https://kubernetes.io/docs/concepts/storage/volumes/#hostpath) Volume attachment |
| Improved network performance | Datadog Agent must run on every host you send metrics from |
| Higher throughput capacity | |
| Packet error handling | |
| Automatic container ID tagging | |

## UDP

**Packet Transport**:
* Kubernetes Service `IP:Port`
* Container Host Port

| Advantages | Disadvantages |
|------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------|
| Does **not** require [hostPath](https://kubernetes.io/docs/concepts/storage/volumes/#hostpath) Volume attachment | **No** packet error handling |
| (**_KubeDNS_**) Does **not** require Hostport exposure if accessible from cluster | (**_Hostport_**) Requires a networking provider that adheres to the CNI specification, such as Calico, Canal, or Flannel. |
| Similar `IP:Port` configuration as Virtual Machine hosts | (**_Hostport_**) Requires port to be exposed on host using `hostNetwork` |
| | (**_Hostport_**) Requires firewall access controls to permit access |
| | (**_Hostport_**) Network Namespace sharing is required |
