NetScaler ADC is an application delivery controller.
Definitely in larger environments, more mature organizations that obviously have the budget to spend and want best in class. Where it struggles is those organizations that don't have the funding and money to spend on it and need more basic functionality. So I'd say that's smaller customers we've worked with and kind of mid-market. They tend to get scared when they get the quotes. Also we've had some struggles with account team consistency. So for the sales team, just a lot of turnover and a lot of missteps on customer calls.
Citrix NetScaler is suited to any environment where hardware load-balancing, application delivery or SSL offloading is a requirement. It's a product that can be used to manipulate traffic flows in a multitude of different ways and its only limit is the protocol, application and imagination of the administrator. It's not a product that includes helpful wizards to guide the admin through each process gracefully. While it is a fairly intuitive product to use, it's not for someone who is not initiated into the ways of networking and network protocols and communication. Nor is this a product that would lend itself solely for the usage of single usage scenarios where small traffic flows would be expected (although if desired the VPX product would probably suffice in that specific scenario depending on the environment)
The great thing is the IP address management that's happening. When you set up the network it's very easy and you don't have to keep on configuring everything together. Again, it's very streamlined and it's one of the biggest players there in the market for this work.
Well, not necessarily the features. I find that we have to change our processes in order to kind of match what F5 BIG-IP does. And it's not a bad thing, it's just that a lot of my engineers want to do it their way, not they F5 BIG-IP way.
It's not difficult to understand the parts of application configurations and features. Setting up new virtual servers with multiple profiles, certificates, and nodes is easy for new users through the web interface, which also translates to programability in scripts, DevOps, or other configuration management use-cases. Users from different backgrounds such as networking and infrastructure can use F5 BIG-IP, while users who are familiar with API calls can easily configure objects without needing to understand the platform at all.
I gave the NetScaler a 7 here because the system once configured and deployed is very easy to use. However, if you did not deploy the system and do not have the fundamental background knowledge then you will have trouble using the product in general. Overall it is a great product and service but does typically require professional services to be deployed.
On the occasions when we've had to engage f5 support, they have been great. They have always resolved our issues quickly and been easy to work with and professional. The reason I give them a 10 out of 10, however, is because when we've had issues that have crossed over between the f5 BIG-IP, our Cisco switches, and our Microsoft IIS server the f5 support representatives have been extremely knowledgeable about every product and device involved and have been able to troubleshoot end-to-end without having to engage other vendors.
Overall, our organization's experience with Citrix support is that support can be hit or miss. Oftentimes it takes multiple attempts and much longer than desirable to obtain a viable solution for issues experienced with their products. It would be great to see Citrix invest time, effort, and almighty dollars into improving their support and bug fix process across the board.
Netscaler has more features than F5 BIG-IP APM product and easier to manage with friendlier user interface for network admins. It was more cost efficient as well and if you have a Citrix XenApp and XenDesktop environment, it is more compatible with those products as well. Our annual maintenance cost is lower as well.
I would say from a security perspective, because I manage security, availability is sort of the key area for us and making sure that is properly handled through BIG-IP, that is the biggest business success, I would say from the product perspective.
