The OpenZiti Network (Ziti) is composed of the following building blocks: OpenZiti Controller, OpenZiti Router, OpenZiti Clients. These components are used in conjunction to provide secure connectivity between two points such as a client to a server. This type of network is considered an overlay network because it provides secure connectivity on top – or “overlaying” – existing networking infrastructure.
