SSH, RDP and VNC console
The console lives inside the browser. No agent, no client, no extension: it opens from any computer, even a borrowed one.
Opening a session
From the server card, the connect button opens the session in a tab inside the panel. You can keep several open at once and switch between them.
Each opening requests a single-use permit from the server, which expires almost immediately. That permit cannot open a second session.
Windows remote desktop
RDP works on every plan, including the free one. The remote desktop adjusts its resolution when you resize the window: it is not a stretched image, the server really changes resolution.
Where the connection comes from
Because everything goes through the browser, connections originate from the SHTERA server address, not from your office. If your servers filter by source address, that address has to be allowed; if they sit behind NAT and cannot be reached from the internet, the answer is per-folder VPN.
How many at once
How many concurrent connections you get depends on the plan. At the cap, a new session waits for one to free up.
