ZeroTier

ZeroTier is a software-defined networking (SDN) solution that creates virtual, decentralized networks. It allows devices to connect as if they were on the same local area network (LAN), regardless of their physical location.

ZeroTier operates by creating a virtual Ethernet switch that is accessible to authorized devices over the internet or other IP-based networks. Each device runs a ZeroTier client, which joins a centrally managed network identified by a unique Network ID. These clients then establish encrypted peer-to-peer connections with each other, bypassing traditional network address translation (NAT) and firewalls.

Key features of ZeroTier include:

• Software-Defined Networking: ZeroTier uses software to control and manage network connectivity, enabling flexibility and programmability.

• Zero-Trust Security: ZeroTier implements a zero-trust security model, requiring authentication and authorization for every device and connection.

• Mesh Networking: Devices can connect directly to each other in a mesh topology, improving performance and resilience.

• Centralized Management: A web-based management console allows administrators to configure and monitor networks, manage devices, and control access policies.

• Cross-Platform Compatibility: ZeroTier clients are available for a variety of operating systems, including Windows, macOS, Linux, Android, and iOS.

ZeroTier is used in various applications, including:

• Remote Access: Providing secure remote access to internal network resources.

• Virtual Private Networks (VPNs): Creating secure VPNs for individuals and organizations.

• Hybrid Cloud Networking: Connecting on-premises networks with cloud-based resources.

• Internet of Things (IoT): Enabling secure communication between IoT devices.

• Gaming: Creating private game servers for multiplayer gaming.
