Tailscale
Mesh VPN built on WireGuard — zero-config private connectivity between devices/services across networks without exposing anything to the public internet. Common self-managed alternative to AWS_PrivateLink for private cross-network service access, and to AWS_Transit_Gateway for simpler multi-network connectivity without true dynamic BGP routing. Consul is the alternative when service mesh/discovery features matter more than raw connectivity.
