​​​​Aligning business strategy and the IT infrastructure

The IT infrastructure is key to the success of virtually any major business initiative, from quickly integrating a strategic acquisition to bringing products to market cost-effectively.

Yet traditional IT architectures are static and inflexible. Any sudden change in business requirements forces IT staff to respond with manual, one-off technology fixes that consume time and resources.

F5 provides strategic points of control throughout the IT infrastructure, enabling organizations to scale, adapt, and align with changing business demands and drive business forward on a solid foundation of IT agility.


F5's Architectural Vision


Your business uses countless applications in a given day. At F5, we built a reputation as an industry leader by helping organizations deliver the most secure, fast, and reliable applications to anyone anywhere at any time. Our pioneering focus on application services gives us a unique advantage in designing the solutions that drive business forward.


F5 Synthesis isn’t built on new products and features. It’s built on comprehensive solutions. We took a big-picture look at the trends affecting businesses today—from security to mobility to performance and beyond—and designed architectures that pull together specific device, network and application scenarios to help you better identify and understand which solutions meet your network needs.

We are the only company that provides an open architectural framework, offering IT organizations innovative ways to deliver services that generate true business value. Our unique framework includes:

  • ​F5 TMOS ®
    F5 TMOS is our universal, shared-product platform that adds intelligence and complete control to application delivery.
  • F5 iRules
    F5 iRules is an event-driving scripting language that customizes how application traffic is intercepted, inspected, transformed, and directed.
  • F5 iControl®
    F5 iControl is an open API that helps automate communications and eliminates the need for costly manual intervention.

DevCentral Membership
