Jason Best

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.

Sulaiman Olubiyi

Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees

Network automation has simplified secure multi-site connectivity and reduced daily operational effort

I believe Cisco ACI could improve by incorporating something related to agentic AI, where it can execute tasks based on particular evaluations or loop engineering, enhancing fault identification or suggestions based on each tenant's configuration. Additionally, I think they should ensure that the documentation is comprehensive. I appreciate that Cisco provides documentation, and their support engineers are helpful in case of any issues. In terms of governance and security regarding Cisco ACI's AI capabilities, I think what we call evals or evaluations is important, whereby the engineer can evaluate the functionalities of the AI in Cisco ACI, preventing it from making deletions or modifications on its own. Therefore, there should be evaluations or guardrails incorporated into the development capabilities. Regarding accuracy and reliability of output for Cisco ACI's AI capabilities, it hasn't met my expectations. What we need is something called RAG, or retrieval-augmented generation. If Cisco can implement that to utilize customer-specific data instead of general knowledge, while ensuring data privacy under GDPR laws, I think that will result in very good, reliable output.

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."

"I think it's an easy, versatile solution to implement."

"It is very stable, allowing us to update firmware on the go without any downtime, which we couldn't do before, with everything redundant so if you shut down one system then another one takes over."

"It is very easy to do the configuration after you know how to work with the product, and it is global, so you change one interface and changes are reflected on every switch."

"Once we have it running, it should be easier for us to program our IT rather than going case-by-case, by switches and different elements, or program it by hand."

"This product improved the way our company functions by enabling us to establish our goal of moving to a zero-trust model. That's how Cisco ACI helps us the most."

"Cisco ACI is a hardware-level product that can support terabytes and petabytes of data at the same time, which VMware NSX can't do because it's a virtual environment with limited throughput and scalability."

"Automation is its most valuable feature."

"It provides flexibility, so you can install it everywhere."

"For clients, a visible GUI dashboard provides a unified view of the network."

Cons

"I think if I was to say something that could be improved, it would be a multi-data center nature of the implementation."

"Its scalability and reliability capabilities should be enhanced."

"We would like to have faster services and problem monitoring for our customers."

"It would be great if ACI would include the next generation firewall feature."

"Sometimes I get stuck with somebody from technical support who does not understand the problem."

"Cisco ACI is difficult both technically to build it out and then operationally to manage."

"The ACI setup is in its initial phases is difficult. The learning curve at the beginning is higher than a normal setup."

"We're still in the process of doing the migration. We haven't migrated completely all of our applications out of our legacy into it yet. It was challenging at first, but getting easier now that we're starting to get into it."

"The only drawback that we are seeing is the user interface is still a little complex and difficult to use. It needs a more user-friendly interface."

More Cisco ACI cons

Pricing and Cost Advice

"The licensing cost depends on the number of switches that are going to be licensed to run the software."

"The pricing is pretty good for new technology."

"The thing that I like the most from Cisco is the support and all the documentation that they have. We do have to pay for it though."

"I don't believe there is any licensing required."

"It is quite expensive. It is not at all on the cheap or medium side."

"The pricing, including both hardware and licenses, is reasonable."

"If you compare the licensing and total cost of ACI, it's cheaper than NSX because of the licensing fees. If you are going for full NSX features it will be too expensive, especially the next-generation firewalling feature."

"The pricing and licensing are both high, particularly if you want a high level of functionality. It would be great if the price and licensing cost could be decreased."

"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."
