Reminder: Don’t Forget about Mobile User Access But for high-availability topologies, you can collocate Edge Servers. One Edge Server can handle 12,000 concurrent users. Is One Edge Server Enough?įor most offices, yes. A Microsoft diagram illustrating some of the Edge Server’s functions. malware), while letting authenticated users through. Together with the Edge Server, these servers/tools create the “perimeter network.” They protect your network from unauthorized access (e.g. Access Edge needs to facilitate external users joining chats. For topologies supporting Persistent Chat, the Edge Server will need to communicate with its server. Edge must communicate with Unified Messaging, in order for external users to get their voicemails. Edge will treat the Office 365 tenant as a federated partner, so make sure SIP Federation is enabled.Įxchange UM Server. If you’re running a hybrid configuration, the Edge Server will have to communicate with Office 365 servers. Otherwise external user connections would just vanish! Obviously, the Edge Server will communicate the most with the Front End (Standard or Enterprise Edition). You may need an XMPP gateway running on the Front End as well.įront End. NOTE: This is not required for all Edge Servers.It makes sure external users can still talk with federated users. Finally, this service sends & receives XMPP messages (eXtensible Messaging and Presence Protocol) from federated partners. That way you’re not missing out on any parts of the conversation. This service enables audio/video, application sharing, and file transfer for external users while in said Meetings. A virtual “ticket to the show,” as it were.

This service allows an external user to join Online Meetings running on your Skype for Business Server. Like a private road through the Internet. This service gives users a trusted connection for inbound & outbound SIP traffic.

Main Components of an Edge ServerĮach Edge Server runs four main services. As such, the Edge will need routable public IPs assigned to it (or non-routable private IPs, if you use NAT). It translates external IP addresses into internal IP addresses to facilitate the external user connections. How does it do that? Essentially, by acting as an IP intermediary. Without the Edge Server, these external users can’t send or receive IM, take phone calls, or join in Online Meetings. partners, vendors), and sometimes even customers. These are mobile users, remote users, federated users (e.g. The Edge Server grants Skype for Business access to users outside the internal network. Please comment if so.) The Edge Server’s Primary Role If you want to hear more about these, I’m happy to dedicate a post to each. (Please note: We will not discuss Reverse Proxies or Load Balancers in this post. In case another user at that customer site, or a future customer’s, still has questions? Let’s take a detailed look at what goes into an Edge Server. But, me being me, I seized on it as a good post idea. Now to his credit, my co-worker answered the question immediately, and (from his impressions) to the user’s satisfaction.

One of the users piped up right afterward. He’d just finished describing the Skype for Business topology we proposed for the customer’s business (hybrid deployment, across 3 offices). One of our team members fielded this question while on-site the other day.
