First, let’s discuss convenience. F5 currently has no plans to remove perpetual licensing options. They offer you the ability to choose perpetual licenses, subscriptions, and flexible consumption plans supporting hardware, software, and cloud features. F5 also has a clear roadmap for BIG-IP’s future and its cloud offerings.
F5 BIG-IP boasts a rich set of features and customisation options. A variety of modules are available to help organisations manage applications, infrastructure, security, traffic management, and optimisation. While NetScaler offers a more streamlined approach focusing on load balancing and application delivery, F5 fits a much broader set of deployments. It packs a powerful toolkit including iRules, iControl, and virtual edition deployments.
One key advantage of BIG-IP is its customisation and programmability via iRules, an event-driven scripting language. With iRules, you can customise how BIG-IP manages application traffic and implement custom security or traffic management policies. Citrix has policies akin to iRules, but many consider F5’s solution more robust.
In the modern cloud era, ADCs need seamless cloud integration. F5 BIG-IP has cloud-friendly offerings like BIG-IP Cloud Edition, as well as tight integrations with all major public cloud platforms. While Citrix offers cloud solutions as well, F5 is generally seen as having stronger and more mature cloud capabilities.
