libcluster provides automatic cluster formation and node discovery for Erlang/Elixir applications, removing the manual steps typically required to connect distributed nodes. It ships with multiple pluggable strategies—such as DNS polling, Kubernetes integration, EC2 metadata/tag discovery, UDP gossip, and EPMD helpers—so you can adapt clustering to your runtime environment. The library supervises a topology process that continually discovers peers and joins or prunes nodes as they become available or disappear. Its design embraces OTP principles: strategies implement a behavior, can be composed, and run under supervision for resilience. libcluster also emits events on nodeup/nodedown, allowing applications to react (for example, rebalance work or update registries) when membership changes. ...

...Participating clusters should be provisioned into a single AWS account, within a single AWS region. Install the The CoreDNS multicluster plugin into each participating cluster. The multicluster plugin enables CoreDNS to lifecycle manage DNS records for ServiceImport objects. The controller must have sufficient IAM permissions to perform required Cloud Map operations. Grant IAM access rights AWSCloudMapFullAccess to the controller Service Account to enable the controller to manage Cloud Map resources.

...The tool is built to show how you can write Kubernetes controllers, use third-party resources, and react to changes in the API via watches and reconciliation loops. It supports DNS-01 challenge flows for ACME, allowing you to validate domain ownership and provision certificates automatically. It also integrates with Secrets and Ingress resources so you can consume the certificates in your applications easily. Although the project is primarily a demonstration or teaching project, it laid groundwork for more mature certificate controllers in the Kubernetes ecosystem.

This is Pen, a load balancer for udp and tcp based protocols such as dns, http or smtp. It allows several servers to appear as one to the outside and automatically detects servers that are down and distributes clients among the available servers. This gives high availability and scalable performance.

...Once installed the script can be used for keeping version controlled Chronos job definitions up-to-date with a Chronos instance. Install DCOS CLI and configure for use "inside the cluster" with configured master nodes. The configuration relies on Mesos DNS to provide the Mesos master and Marathon endpoints.

Freyr is a resource monitor/dynamic DNS updater that allows dynamically change DNS records for different services depending on their state. So you'll be able to keep only active IP addresses in your DNS database.

Eddie acts as a high availability WAN and LAN clustering tool for web servers (including Apache). It provides load balancing at two levels (DNS and LAN), failover redundancy, and admission control to maintain quality of service levels.
