Citrix ADC (NetScaler)
The Alternative to F5 BigIP

With many workloads moving to a hybrid cloud architecture, your delivery controller needs to be as flexible and elastic as your services demand. Citrix ADC, formerly NetScaler, offers significant agility and user experience visibility advantages over F5 solutions as well as potential cost savings with efficient, flexible licensing.

4 Reasons To Choose Citrix ADC 

We’re a Citrix Networking Specialist Partner with a track record in the successful migration of services from 3rd party solutions to an agile, flexible delivery infrastructure powered by Citrix ADC & ADM.

Working with our customers, we’ve seen 4 key areas where we’ve been able to use Citrix Cloud Networking technologies to help do things better.

Scroll down to learn more, view our e-Books or schedule a call with us to talk about how we can how Citrix ADC could work for you.

1 - Citrix boosts service & business agility

Having a single place to see, measure and manage service delivery significantly improves operational efficiency and reduces cloud friction which in turn increases service and business agility.

F5/Ngnix management points

  • Big IQ for traditional 3 tier delivery
  • Ngnix Controller for microservices
  • f5 Beacon for traditional Service Mesh
  • Aspen Mesh for microservices Service Mesh
  • Ngnix database

+ management agent per Ngnix instance

Citrix management points

  • Citrix Application Delivery Manager

2 - Citrix reduces licence cost

Citrix enables more efficient use of licences, reducing service cost.


  • Rigid licence model for virtual appliances with 25Mbps, 1Gbs, 3Gbps, 5Gbps or 10Gbps limitations. Typically results in appliances having to be over provisioned, effectively paying for capacity that won’t get used.
  • Only offer 5 throughput based licence options, restricting deployment flexibility.


  • Citrix Pooled Licensing enables virtual appliances to be provisioned with any increment of 500Mbps up to 100Gpbs, significantly increasing licence efficiency, agility and service scale.
  • vCPU allocation based licence model allows appliances to be deployed based on computational workload rather than throughput, allowing licences (and cost) to be utilised with maximum efficiency for the specific use case. Better licence utilisation reduces service cost.

3 - Citrix reduces operational effort & expenditure

From physical to virtual, all Citrix ADC appliances share the same code base, so the same features, configuration and APIs can be used across all deployment scenarios.


  • Big IP for North South traffic
  • Big IP Virtual Edition
  • NGINIX for East West traffic

(No way to manage or have visibility in to both)

A decision will be needed as to which platform and tools to use, increasing cloud friction, slowing agility and introducing opportunities for error.


  • Citrix Application Delivery Controller

Complete flexibility allowing configuration to move across all deployment scenarios, reducing administrator effort, eliminating cloud lock in and significantly improving business agility.

4 - Citrix improves service visibility

Citrix Application Delivery Manager includes a Global Service Graph and Infrastructure Analytics that provide complete end to end service visibility from the back end server to the end point, regardless of application architecture or origin.

Citrix provides

  • Detailed web transaction analytics from the client to the server.
  • App performance correlated directly to the infrastructure it is running on – faster incident remediation.
  • Machine Learning to help identify service anomalies and SLA threats.
  • TLS insights and certificate management to reduce admin effort.
  • The ability to view and analyse the entire user request from end to end, across the network – quickly identify infrastructure issues or service bottlenecks.
