F5 BIG-IP
Pros
- + Consolidates load balancing, SSL/TLS offload, WAF, firewall/DoS mitigation, access/VPN and DNS on one policy engine
- + Thirty-year reliability track record in banks, carriers and governments; mature HA clustering
- + Full-proxy architecture with programmable iRules for traffic logic that generic load balancers cannot express
- + Runs everywhere: hardware appliances, VIPRION/VELOS chassis, and Virtual Edition on VMware, KVM, Hyper-V and major clouds
- + Dual-stack IPv6 support and ICSA-certified firewall with automatic and dynamic DoS signature handling
Cons
- - Very expensive: throughput-tiered licenses, module add-ons and six-figure support contracts
- - No public list pricing — real cost only emerges through partner sales processes
- - Steep learning curve: its own OS (TMOS), its own DSL (iRules/TCL, AS3) and its own upgrade rituals
- - Overkill for simple HTTP load balancing where cloud-native or open-source options cost a fraction
- - Company is steering toward subscription and Distributed Cloud; multi-year renewal terms need pinning down

- + Free managed WAF ruleset, Universal SSL and unmetered DDoS protection by default

Cons
- - No uptime SLA below the Business plan
