Any alternatives?

The component does not have any alternative that we know of, but we plan to remove it in 2025.

Integrates with other components?

Memberlist is the main component of the Gossip DNS feature.

Gossip-based clusters use a peer-to-peer network instead of externally hosted DNS for propagating the K8s API address. This means that an externally hosted DNS service is not needed.
Gossip does not suffer potential disruptions due to out of date records in DNS caches as the propagation is almost instant.
Gossip is also the only option if you want to deploy a cluster in any of the AWS regions without Route 53, such as the China and GovCloud ones.
