The Exchange Server platform, the power behind Microsoft Outlook’s features remains at the forefront as acalendaring software, mail server, and contact manager for organizations. WebMux Network Traffic Manager plays a key role in load balancing the network data between the Exchange back end servers/server farms assuring clients’ data are delivered reliably to their destination points.
WebMux’s extensive load balancing capabilities support a wide-range of TCP and UDP based Internet protocol (IP) applications and services including other Microsoft applications such as Skype for Business, Lync Server, Sharepoint Server, Xbox Live Games Server, and Internet Information Services (IIS) for Windows Server.
The WebMux setup and configuration wizards are one of multiple options that lowers the complexity bar when setting up an enterprise-class Network load balancing/ADC solution for today’s sophisticated applications and services. The Exchange Server wizard removes the need for any scripting and make the deployment of WebMux quick and easy.
The interface optimizes the use of smartphone and tablet mobile technologies that increases the WebMux management convenience and ease in today’s highly mobile work environment.
WebMux Flexibility and Scalable Platforms
WebMux High Performance
– WebMux uses the 64-bit processor platform and developed using intensive algorithms to provide the high capacity, reliability, and availability
– WebMux appliance models are built with the best-in-class server-grade hardware with up to 16-core CPU processing power to provide outstanding, feature-rich performance for extensive cryptographic, compression, and network traffic management functionality
WebMux Extensive Features (Included in all models)
All WebMux models have four (4) load balancing operation modes with each mode having its advantage. The number of Arms refers to the number of physical networks. There are one or two LAN connections (typically External and Internal). Both IPv4 and IPv6 are supported and work in all operation modes.
One-Armed Single Network is a special case of bridging in which the WebMux bridges internally on one interface (that can be bonded for higher capacity). The bridge loop issue is elimiated. Note that all traffic is “source NATted” (aka SNAT)–so the WebMux becomes the client and the server does not see the IP address of the client. A limitation of this configuration is that an additional IP address must be assigned to the WebMux for each 65,000 simultaneous connections–because of that SNAT configuration and client-server relationship.
One-Armed Direct Server Return (DSR) the highest-performance option in cases where it is supported, also known as “Direct Routing” or “Out-of-Path (OOP)” this makes the WebMux the traffic director for incoming traffic but return traffic can route back bypassing the WebMux (unless the WebMux does SSL termination). Note that this requires a simple configuration of a “loopback adapter” on the servers and also not there is no performance advantage if SSL or TLS termination is required as the WebMux becomes the endpoint for the SSL/TLS security relationship.
Two-Armed Network Address Translation (NAT) is the required configuration when you have two subnets. It is the common “Destination” NAT configuration in which the clients connect to an IP address on the WebMux and the WebMux proxies to the back-end servers. The servers “see” the IP address of the client, as if the WebMux was not there. This is the required configuration when there are two IP subnets (Internet-side and Internal).
Two-Armed Transparent makes the WebMux an inline bridge–seeing all of the traffic below the IP layer and able to manage traffic without IP address changes. Note that, being a bridge, you must avoid bridge loops–having a circular path through inter-connected bridges. Also, being inline and Two-Arms, the load-balanced traffic flows through the WebMux.
