are you saying that because you can have multiple proxies, they aren't centralized? or that at least this is one mode you can use, but the standard one is using a proxy?

* Proxy is used to handle SSO, Web UI and intercept traffic for session capture. You can have one proxy per your organization, multiple proxies or, if you don't want to intercept traffic, no proxies at all.
* Auth server is used to issue certificates and send audit logs and session recordings to external systems.
* Nodes (end system agents) sometimes are helpful, but not required. For example, if you want to capture system calls in your SSH session, you can deploy node. Or you can use OpenSSH with Teleport if you wish.
Because Teleport is based on certificate authorities, the following deployments are possible:
* One, "centralized" HA pair of proxies intercepting all your traffic (K8s, databases, web, etc). This is actually helpful for many cases, as you have just one entry point in your system to protect, vs many.
* Multiple, "decentralized" proxies in multiple datacenters. This is helpful for large organizations with many datacenters all over the world.
* No proxies at all. You can issue certificates with or without Teleport and reach your target clusters directly, as long as they trust the CA. It's a bit harder for managed K8s, but easy to do with self-hosted K8s, SSH, Databases, etc that support mTLS cert auth. This is super helpful for integrations with larger echo system - any system that supports cert auth should work with Teleport out of the box.
* You can have one auth server HA pair managing a single certificate authority.
* You can have multiple, independent auth servers (teleport clusters) with certificate authorities and trust established between them.
* You can use your own CA tooling with Teleport.
The way we think about Teleport is that it's a combination of certificate authority management system, proxies (intercepting traffic and recording sessions) and nodes (for some services, like SSH providing advanced auditing capabilities with BPF).
You can combine those components, or replace them with whatever makes sense.

like it's your Basic Architecture in the diagram in your docs. so i feel like i'm being put on.
