Data center network architect at Cloudwire
A flexible solution that can be integrated with third-party solutions whilst maintaining its automated nature
I think if I was to say something that could be improved, it would be a multi-data center nature of the implementation. Meaning, having an active-active data center with multiple entrance-exit points. I think that feature could be improved to provide a kind of anycast gateway solution into the functionality that would make it a lot more flexible and versatile. Maybe also making the solution a bit more like the NSX-T from VMware, more on the logical part of the solution, like micro-segmentation and the ability to have a distributed firewall across the whole solution, to implement it in an easier way than they currently do with the security aspect of the solution.

Enables streamlined data center management with automation and application-centric design
The main features of Cisco ACI that I really appreciate are the application-centric and network-centric designs, allowing you to create your network according to your application. That's helpful, and it's good for one-time implementation. The automation capabilities are really helpful. We deployed one data center using Terraform, and after deployment, many automation features are available, which can be very helpful. Based on my experience, Cisco ACI provides substantial capability; you can design your network accordingly and it's part of the SDN family, providing many benefits to the organization, especially when moving from traditional network infrastructure. Many organizations are actually using the old traditional Nexus infrastructure or some old data center devices. It gives you significant control and one-time implementation capabilities, and it also provides better performance and security. Functionality-wise, Cisco ACI provides integration using automation. We implemented it through Terraform, which was easy. Those features are available, so I don't think any new features are needed right now; something new could come up, but they have implemented many improvements over the years.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"What I liked about the solution is the quick and easy way you can build a network data center fabric."
"We use Cisco ACI for perimeter security and threat detection."
"I rate Cisco ACI nine out of ten due to its impressive features."
"Centralized management and control of the entire data center environment and its architecture."
"The stability is quite good."
"With Cisco ACI, I can deploy things with a script, then run it in five minutes."
"It has the fastest automation. You can move and deploy services in just a couple of minutes."
"I have found the SDN features to be the most valuable."
"The centralized management of the entire network data center, in this case with ACI, is the most valuable feature. By having access to some powerful APIs you can build your own tool to speak to the ACI controller, then with that, you can deploy things really fast. Having the option to build your own tools and then using the centralized management of the ACI to push the configuration to the network devices is very valuable."
 

Cons

"I think if I was to say something that could be improved, it would be a multi-data center nature of the implementation."
"We have had two calls with technical support. They are not the best. We opened a case to diagnose issues and it's taken weeks to get someone on the case and to move forward."
"Since it is a new technology, Cisco moved all the menus. This made it tricky to use."
"Cisco SDN will only work with its own devices, so that's a downside."
"From my point of view, troubleshooting issues relating to ACI can be a little bit complicated to perform."
"The challenging thing about Cisco ACI was we had to put a lot of effort into providing the customer the full picture, new standards, and new technology that they had to use. This was more challenging than deploying the product."
"It would be nice if I could specify network-centric in my design, and the system would organize and set itself up in that way."
"I would like to be able to test the upgrades in a simulation before implementing them in production because not everyone has a lab."
"The ACI setup is in its initial phases is difficult. The learning curve at the beginning is higher than a normal setup."
 

Pricing and Cost Advice

"The licensing cost depends on the number of switches that are going to be licensed to run the software."
"Pricing for Cisco ACI could be expensive if you're not a gold partner. If you're a gold partner, you'll get reasonable pricing, but to become a gold partner, you must cross several layers. For example, at least twenty engineers within your organization have to be certified, with each certification priced at £2,000 minimum, so this would make some companies think twice about the product. If you're going for Aruba and Juniper products, on the other hand, you can quickly get the partner status, and you can start selling the product. As a gold partner, you can get up to seventy percent discount on Cisco ACI, for example, while an ordinary partner gets ten percent off. Cisco ACI is expensive for both customers and partners, but I'm rating pricing for the product as four out of five because even if the price is costly, you get a lot of benefits from the product. Cisco ACI isn't the best, price-wise, but it's still a good solution. If you're in a small organization, you may be unable to afford it. Cisco ACI is best for enterprises but not SMBs because Cisco ACI and its required resources are expensive."
"A big company can automate it themselves or spend a lot of money and buy it."
"The price could be improved. It is expensive, but then again, it is Cisco. The price is worth what you pay for."
"It is quite expensive. It is not at all on the cheap or medium side."
"The product is not cheap."
"Price is always an issue."
"Cisco ACI costs depend on how many sites you have. One simple site with a simple installation, including two leaves, two spines, and some fibers, would cost $200,000 to $300,000 for the licenses. The solution is a bit expensive, but it's a good investment if you want your data centers to work without interruption."
"This is an expensive solution."
