zrok
zrok is a service designed to provide frictionless access to ephemeral, geo-scale reverse proxy capabilities.
Characteristics
zrok has the following characteristics:
Frictionless
zrok is designed to provide a "frictionless" experience. A single binary and a single command are all that is required to take advantage of all of the power of zrok.
zrok works in a large number environments: developer shells, container sidecars, serverless environments, webhooks.
Expand with OpenZiti
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.
Bring zrok into your existing OpenZiti deployment to provide rapid, ephemeral connectivity for a number of important HTTP scenarios.
World-Scale
zrok is the software that powers the zrok.io world-scale service. zrok can scale as large as you need.
Multiple Isolated Tenants
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.
Self-hosting Capable
Install zrok on top of your own OpenZiti network. zrok is simple to operate and scale.
Concepts
zrok is conceptually structured like this:
zrok Frontend, zrok Backend
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.
