BIG-IP software products are licensed modules that run on top of F5's Traffic Management Operation System® (TMOS). This custom operating system is an event driven operating system designed specifically to inspect network and application traffic and make real-time decisions based on the configurations provided. The BIG-IP software can run on hardware or can run in virtualized environments. Virtualized systems provide BIG-IP software functionality where hardware implementations are unavailable, including public clouds and various managed infrastructures where rack space is a critical commodity.

BIG-IP Primary Software Modules

BIG-IP Local Traffic Manager (LTM) - Central to F5's full traffic proxy functionality, LTM provides the platform for creating virtual servers, performance, service, protocol, authentication, and security profiles to define and shape application traffic. Most other modules in the BIG-IP family use LTM as a foundation for enhanced services.
BIG-IP DNS - Formerly Global Traffic Manager, BIG-IP DNS provides similar security and load balancing features that LTM offers but at a global/multi-site scale. BIG-IP DNS offers services to distribute and secure DNS traffic advertising application namespaces.
BIG-IP Access Policy Manager (APM) - Provides federation, SSO, application access policies, and secure web tunneling. Allows granular access to various applications, virtualized desktop environments, or just go full VPN tunnel.
Secure Web Gateway Services (SWG) - Paired with APM, SWG enables access policy control for internet usage. It can allow, block, verify and log traffic with APM's access policies allowing flexibility around an organization's acceptable internet and public web application use.
BIG-IP Application Security Manager (ASM) - This is F5's web application firewall (WAF) solution. Traditional firewalls and layer 3 protection don't understand the complexities of many web applications. ASM allows users to tailor acceptable and expected application behavior on a per application basis . Zero day, DoS, and click fraud all rely on traditional security device's inability to protect unique application needs; ASM fills the gap between traditional firewall and tailored granular application protection.
BIG-IP Advanced Firewall Manager (AFM) - AFM is designed to reduce the hardware and extra hops required when ADC's are paired with traditional firewalls. Operating at L3/L4, AFM helps protect traffic destined for the data center. Paired with ASM, the user can implement protection services at L3 - L7 for a full ADC and Security solution in one box or virtual environment.

BIG-IP Hardware

BIG-IP hardware offers several types of purpose-built custom solutions, all designed in-house at F5. BIG-IP hardware is offered via series releases, each offering improvements for performance and features determined by customer requirements. These may include increased port capacity, traffic throughput, CPU performance, FPGA feature functionality for hardware-based scalability, and virtualization capabilities. There are two primary variations of BIG-IP hardware, single chassis design, or VIPRION modular designs. Each offer unique advantages for internal and collocated infrastructures. Updates in processor architecture, FPGA, and interface performance gains are common so we recommend referring to F5's hardware page for more information.
