Can we continue to use our existing firewalls and load balancers?

Yes, if you currently have load balancers in place you can continue to use them. You’ll just configure them to forward the relevant Skype for Business traffic to SphereShield’s Bastion reverse proxy.

Load balancers must be configured to use session persistence/stickiness, so that individual clients don't switch between Bastion servers during one session.

Cookie or IP address based persistence is supported.

Both active-active and active-passive load balancing are supported, although active-passive
can make troubleshooting easier during deployment.

All load balancing methods are supported, including least sessions (best practice), round robin, ratio and least connections.

We have existing customers happily using F5, Kemp and Citrix load balancing products.
