Citrix ADC vs. F5

Citrix ADC features software-driven architecture that delivers performance and scale without a heavy reliance on custom hardware, blades, or chassis systems.

As businesses embrace the cloud, hybrid has become their new reality, resulting in a complete end-to-end network infrastructure from the data center to the cloud. Investment in hardware across the data center are being reconsidered as applications migrate to the cloud.

Only Citrix ADC

  • Provides flexibility to license ADC instances interchangeably between your on-premise data center and the cloud, across any form factor
  • Offers application and infrastructure intelligence for applications deployed on premises or in the cloud, as a service
  • Includes a complete end-to-end app delivery solution that encompasses server-side and WAN optimizations, in addition to securing access to SaaS environments
  • Provides a comprehensive device package for Cisco ACI deployments
  • Supports up to 115 virtual ADC instances on a single physical appliance
  • Provides support for heterogeneous digital workspace solutions

Citrix ADC advantages over F5

Feature Citrix ADC
F5 The Citrix ADC advantage
Single management console for configuration, orchestration, and analytics
Citrix ADC configuration management has unique capabilities:
  • Configuration advice and audit
  • Manage HAProxy instances
  • Integrated service orchestration with Cisco API, VMware NSX, OpenStack and Mesos
Advanced analytics
Anomaly detection with proactive alerts based on server responsiveness, uneven load balancing, and DNS vulnerabilities with machine learning
Security analytics Limited Security-insights-based approach for threat and safety assessment, providing a visual representation of app vulnerabilities and attacks. Provides recommendations for configurations to increase security posture.
Gateway analytics Limited Provides insights to help admins troubleshoot remote logon issues based on specific applications, users, and logons.
Multiple for factors including containerized
  Citrix ADC leverages the same code base across hardware and software; including a native containerized service that runs in a Docker container. Includes support for Mesos/Marathon and Kubernetes.
Flexible licensing for shared capacity
Limited Citrix ADC offers a pooled-capacity licensing model that allows capacity to be shared across hardware- and software-based instances. F5 only allows iSeries licenses to be transferred to the cloud on their virtual edition, no shared concurrent capacity allowed.
Support for vitual guest instances (multi-tenancy) on an appliance

Citrix ADC provides differentiated multi-tenancy:

  • Support for FIPS appliances
  • Third party workloads supported
  • Highest instance density on an appliance
Software based capacity upgrades (Pay-grow)
Limited Citrix ADC allows pay-grow for all appliance attributes. F5 only provides for SSL and HTTP increases, bandwidth is not upgradeable.
Instance and appliance clustering
Limited A complete clustering solution at L2 and L3, includes traffic steering capabilities across a single data plane.  
Software centric design Dependent on custom hardware Citrix ADC leverages innovation and performance in software that can be deployed on commodity hardware or in the cloud.
Common code base across multiple form factors and deployment scenarios Different versions across form factors, hardware centric bias Citrix ADC leverages the same code base/API across every form factor to ensure the highest levels of feature parity
