Sentiment score

For stability, Cisco ACI rates a nine or 9.5 because I've seen three customers using Cisco ACI and once deployed, the solution is very stable.
Network Technical Manager at KPMG
Cisco ACI is stable in my experience.
Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees
 

Room For Improvement

Cisco ACI struggles with complexity, user-friendliness, cloud integration, security, cost, and support, hindering customer adoption and satisfaction.
Nuage Networks could improve documentation, simplify setup, enhance customer support responsiveness, offer better training, and improve system integration.
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.

Their lack of on-ground offices can result in business losses.
Chief Technology Officer at Mehbub General Trading PLC
We do not make use of its visibility and analytics features, as we are mostly using it for the networking part only.
S VP, IT Infra at ATOM
 

Setup Cost

Cisco ACI is costly but valued for reliability, with discounts for partners, justifying the investment in uninterrupted operations.
Nuage Networks provides customizable and competitive pricing for scalable solutions, appealing to enterprises with detailed, requirement-based quotes.
In general, Cisco ACI is on the higher side; it's not a cheap solution.
Network Technical Manager at KPMG
Cisco's pricing tends to be on the higher end compared to other vendors.
Chief Technology Officer at Mehbub General Trading PLC
Regarding pricing, setup costs, and licensing for Cisco ACI, I observe that it is on the more expensive side.

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.
Network Technical Manager at KPMG
Instead of taking days or multiple days for a deployment of a server or application, they can do it immediately within minutes because all the configuration templates are already there in the control plane.
Consulting & Solution Integration at a comms service provider with 10,001+ employees
With the Cisco ACI fabric, you manage them as a whole, and it's an automation-driven solution, with our network development team integrating with the APIs to establish workflows for observability, fault alerts, monitoring, and more.

Featured Reviews

Sulaiman Olubiyi - PeerSpot reviewer
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.
