Akamai is a well-established brand name with a great product. It meets and many time exceeds the needs for global content delivery and security management layer at the edge. Fine grain security tuning seems cumbersome as the definition of the app keeps changing. It also requires an investment of time for the setup which doesn't necessarily make sense for smaller scale scenarios. Some products offered by AWS, Azure or the Google Cloud can be more tightly integrated with cloud provider offerings thus easier to configure.
Citrix Netscaler can be a powerful network appliance for environments that are fully committed and open to utilizing a network appliance that isn't made by a traditional network vendor. Administrator user experience has improved over the years and will continue to improve with the flexibility of virtual and physical appliances available for medium and large enterprises.
Content offloading - once rules are set up within Akamai you don't need to even think about how many images or large JavaScript or CSS files (for example) are being served from your own estate, Akamai takes care of it all via rules that are quick, easy and flexible.
Page caching - for pages that don't change very often Akamai allows you to set up rules, quickly and easily, to serve up your page content for you, which takes even more load away from your origin servers.
Quick rollback - the Akamai system allows easy testing of rules and changes via a staging system, and also offers a quick rollback option, which is perfect for the rare occasions when something has been set up incorrectly.
Flexibility. NetScaler assumes its admins know a bit about networking and in-depth details surrounding the applications they are configuring access for/to. This being so, the range of configuration options is very broad allowing various versions' combinations of protocol patterns, expressions, rules etc., all to the benefit of the admin.
Granularity. Having such a broad range of configuration options available, while still allowing simple options to be configured simply. The GUI is well-stylized and navigation has a good flow.
Ease of control. For load-balancing of simple services right out of the box, NetScaler makes it pretty easy, compared to the range of options available in the surrounding GUI and under the hood.
The interface in their control centre could be a bit more user-friendly with some of the settings in places that you wouldn't expect them to be. The search offsets this problem to an extent but it's still sometimes slower than you'd like to find what you are looking for.
The documentation could use an overhaul with specific examples related to the command line as well as GUI. Explanations in the documentation would also be helpful.
Being able to have more than just one routing table would allow the ability to leverage security.
Improve on the specifics I mentioned previously and could be a 10/10 product. It is also a confusingly branded product that I have supported in two large enterprises where IT departments are unsure if the product belongs to the Citrix remote access support team or the Network infrastructure support team (it should be the later) and typically under utilized.
Their support documents are excellent and provide a lot of useful information for all their services. The only reason I didn't give them a 10 is that the time it takes for them to respond to an issue could be slightly faster.
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.
We've used -- and considered -- a whole number of CDN offerings. The good news is that almost all of the CDN products on the market are terrific, and will pay for themselves via increased customer satisfaction and lower monthly hosting bills. For some cases, we're still more likely to suggest CloudFlare (which has a free tier) or an integrated offering from a cloud provider, like Cloudfront.
We chose Citrix ADC over Kemp and F5 due to additional integrations with various products such as Citrix/Horizon/Monitoring tools. We additionally chose ADC due to better ease of use and ability to have the appliances be virtual or physical, with the configuration being a simple migration of code which provided flexibility to be able to do a hybrid environment with ease.
Akamai RoI improved over a period of times since it comes with heavy costs, however global deliveries in over 100 counties and global web platforms usage helps improve RoI
With the complex UI challenges, ROI could be impacted negatively when you have to invest in operations and time.
