Pros
It is the best product out there.It has an easy user experience and user interface. The security is effective and better than its competitors.This product protects us from Internet attacks using its firewall features to block any attacks.Scalability is great. One of the best features of NetScaler is that it can scale out.This solution allows the user to easily scale out application delivery, and provides secure remote access.One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low.I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production.Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature.

Load balancing generally brings high availability and a bigger ability to scale out. In some cases, it brings security, depending on how it is configured.The detail that you have available when setting up iRules.Where we are finding the AWS version helpful is when we are trying to scale up new environments. AWS Marketplace helps here a lot.I was able to simply and quickly set up the WAF rules and security, and also set up easily complex policies and rules which gave me some great features to redirect.It has so many features. ​First of all, it has a full proxy architecture, it has multiple modules. The best feature is the WAF, the web application firewall module. It also has cashing type capabilities. It has all kinds of load-balancing algorithms based on your IT requirements.It provides first-tier firewalling, for you application. And it provides server load-balancing, it provides optimization, and it provides a proxy feature, where your users cannot directly access your server. It acts as a fully proxy architecture. It has client-side and server-side connections, both, and they're separate.It also has an AVR feature: application, visibility, and recording. It's good for customers looking for what is actually happening in their network and where the latency is.it has TCP LAN and WAN optimization features. It has has caching.

Cons
It can be difficult to setup.We would like to see more monitoring features going forward, because the current product monitoring options are not enough for security usage.I would like to see more integration for single sign-on.Should offer more flexible cost-effective licensing for small to medium sized organizations.The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified.In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it.Development team's response time could be better.Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used.

I would like them to expand load balancing, being able to go across multiple regions to on-premise and into the cloud. This could use improvement, as it is sometimes a little cumbersome.For integration with other AWS environments, we do some tie-ins with some autoscaling groups. This has been challenging for us. We have had issues, where when autoscaling groups scale up, there are some instances which are not showing up in the proper size. Then, those IPs would get registered with F5, but never get released. Therefore, we are ending up with a whole bunch of ghosted IPs.The management interface is unclear, complex, and not concise. I would like a better user interface.I used GitHub for autoscaling CloudFormation, and I found two bugs and I submitted them. Their implementation in GitHub could be cleaner and allow for a bit more customization.They need to develop the reporting tools further.The one gap I saw was that pure LBN integration is a little tricky. The insertion of F5 in LBN is a little tricky. They need to work on something, on products by which they can insert F5 in any sort of cloud environment.They need to improve the interface and some of the functionalities.We need best-practice information. They have something called DevCentral and a blog. But we want something from F5 itself regarding how to tackle the false-positive configurations. If you go into detail with so many configurations it will find so many false positives from the moment it is enabled that it will quickly impact your applications, and it will not work.

Pricing and Cost Advice
I do not have any experience with the pricing of the product.We are quite happy with price. It's not too high.The licencing model that we bought has been good. The licencing model is more flexible.We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high.It all depends on the features that will be used and the number of accesses.Costly product and complicated licensing.It's not for startups or SOHO.

It could be priced a little less, especially on the virtual side. It gets a bit expensive, but you get what you pay.The cost that they have with AWS are almost prohibitive. I'm being forced to use F5 WAF. I would not simply use it based on cost. I agree that they have some great features, but for me, cost is key in terms of AWS.I am a fan of using AWS natively. It is much cheaper.It's fair, it's not too expensive. Maybe just a little high.The pricing is inclusive of many features.Security should be involved in any base license. When you bring on F5, you only have default license. Then, the ASM product license has to be purchased. It would be great if F5 could include the ASM in the base license.It is the best solution, but that comes with an increased price.Try to negotiate all the software features that you require upfront.
