A F5 Networks Case Study
Wer Liefert Was (WLW) is the leading B2B supplier search site in Germany, Austria and Switzerland, serving about 1.6 million decision makers per month and listing over 500,000 suppliers. WLW needed to replace end‑of‑life load balancers with a high‑performance, secure Application Delivery Controller that provided firewall and user‑identification features, cookie‑based client tracking, SSL scheduling, richer logging and scripting, and simpler administration—so it selected F5 Networks’ BIG‑IP Local Traffic Manager (LTM) ADC.
F5 Networks implemented BIG‑IP LTM (BIG‑IP LTM 3600) across WLW’s data centre, centralizing SSL offload, using iRules for access and rights management, and consolidating roughly 120 configured virtual servers (about 55 actively addressed). The result: fast deployments (new F5 system in ~30–45 minutes; a new virtual server in minutes), replacement of three software load balancers, reduced maintenance time (estimated high single‑digit percentage savings), fewer systems to support, virtually no downtime, improved user tracking and streamlined administration—freeing resources, lowering costs and improving time‑to‑market.
