`zrok` is a service designed to provide frictionless access to ephemeral, geo-scale reverse proxy capabilities. `zrok` is implemented on top of OpenZiti as a _Ziti Native Application_.
`zrok` is designed to provide a "frictionless" experience. Only a single binary and a single command are required to take advantage of all of the power of `zrok`.
`zrok` is built on top of OpenZiti, a next-generation solution for secure application connectivity. `zrok` is a fantastic way to start working with OpenZiti. Start with simple `zrok` ephemeral connectivity, and then layer on additional capabilities provided by the underlying OpenZiti network.
A single `zrok` instance can support any number of isolated tenants, allowing them to coexist on top of the same OpenZiti deployment in a secure manner.
The `zrok` reverse proxy is broken into two halves, a _frontend_ and a _backend_. These two components connect over an OpenZiti network. Together the frontend and the backend work together to implement a reverse proxy.
The frontend is designed to be sited on an accessible network (typically the public internet). This allows traffic from that accessible network to ingress into the `zrok` frontend, across the dynamic reverse proxy.
The backend is designed to be sited in a private environment, such as a private development server, or a serverless environment, or a container sidecar. The backend only needs outbound connectivity to reach the OpenZiti network and the `zrok` controller.
The controller is a lightweight control plane component, which orchestrates connectivity between frontend and backend components.
