Citrix ADC Review
Some of the valuable features are load balancing, reverse proxy, and AAA authentication.
What is most valuable?
- Load Balancing: Why? Availability/Performance: Those are the core features of the product and the main reason for the purchase of an ADC in my company. These features bring a lot of resources that improve the experience of the users.
- NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections).
- Global Server Load Balancing: Why? Availability: Bring us the possibility to load balance our ISPs links, delivering DNS responses thru available ISP providers.
- Reverse Proxy/AAA Authentication: Why? Availability/Security: Many local websites/applications are now available through the internet, with NetScaler acting as reverse proxy, and through AAA authentication in order to authenticate only necessary users.
How has it helped my organization?
We are replacing the necessity of any kind of load balance software/components (like Microsoft NLB, SAP Web Dispatcher, DNS Round Robin) and begin to centralize all Load Balancing necessities in the same NetScaler Hardware.
What needs improvement?
The product provides some templates to integrate with applications like MS Exchange, MS SharePoint, SAP Enterprise Portal, and others. However, the last update for these templates was 2013 (lots of applications are running on versions newer then 2013).
For how long have I used the solution?
We have used this solution for four years.
What do I think about the stability of the solution?
We deployed this solution in a two-node cluster. In the beginning, we struggled to make it work properly. We also felt a lack of documentation for complex environments like ours. After some time and with external help, we make it work as it was supposed to function.
What do I think about the scalability of the solution?
I did not encounter any issues with scalability.
How is customer service and technical support?
I would give technical support a rating of 7/10.
How was the initial setup?
The initial setup was complex. Usually, NetScaler implementations are made using the HA feature. We adopted the cluster feature. We noticed that there was a lack of knowledge from the community and Citrix support in this area. Our complex environment of network made the initial setup more difficult.
Which other solutions did I evaluate?
We evaluated F5 and Brocade.
What other advice do I have?
Be careful in the choice of a partner to implement this product.
