Overview

Product Information on Cisco ACI

Updated 13th October 2025

What is Cisco ACI?

Cisco Application Centric Infrastructure (ACI) is a software-driven solution designed for data center networking and automation. The software provides centralized policy-based management, automation of network services, and support for multi-cloud environments. Cisco ACI enables integration of physical and virtual network elements, facilitating application agility and scalability. It addresses business challenges related to network performance, security segmentation, and resource optimization by allowing organizations to streamline operations and maintain consistent policies across various infrastructure components. The software includes features for monitoring, troubleshooting, and advanced analytics to assist with efficient network provisioning and maintenance.

Cisco ACI Pricing

Cisco ACI is a software that uses a tiered licensing model based on features, capacity, and scale requirements The software offers different subscription and perpetual licensing options with pricing that varies according to the number of managed endpoints and additional functionality required for advanced use cases

“Policy-Driven Cisco ACI Architecture Minimizes Network Outages and Configuration Errors”

5.0
Aug 19, 2025
This feedback reflects our experience with Cisco Application Centric Infrastructure (ACI) after more than seven years of continuous use in our production data center environment. We consider Cisco ACI to be an exceptionally reliable and mature platform. It has fundamentally transformed our data center network operations from a traditional, manual framework into a modern, policy-driven system. The initial investment in training and migration has paid significant dividends in terms of stability, agility, and reduced operational overhead. The most significant impact of ACI has been a dramatic improvement in network availability. The architecture's inherent redundancy and fault isolation capabilities have proven robust. More importantly, the policy-driven model has drastically reduced network outages caused by human error and misconfiguration. By defining network intent through the network controller as a single source of truth, we have eliminated the inconsistencies that often arise from device-by-device manual changes. ACI's API has been a critical enabler for our automation strategy. We extensively use automation frameworks to manage the entire lifecycle of our network configuration. We have successfully integrated ACI with our broader technology domains. This includes seamless integration with security platforms to automate security policy enforcement and with business applications to dynamically provision network resources based on application needs. In summary, Cisco ACI has proven to be a foundational technology for our modern data center. Its reliability is unquestionable, and its ability to serve as a programmable, automated network fabric is unmatched in our experience. It has successfully reduced operational risk while simultaneously increasing business agility

Performance of Cisco ACI Across Market Features

Cisco ACI Likes & Dislikes

Like

1. Policy Model (EPG, ESG, and Contracts) - You simply declare the intent of what should be allowed, and the ACI fabric figures out the rest. 2. Micros-segmentation - workloads cannot communicate with each other unless explicitly allowed by contract, even within the same group. 3. Service Graphs - identify a chain of L4-L7 services as a policy.

Like

Ability to troubleshooting packet flow thoughout fabric, expan subnets though multiple DCs without headache about L2 broadcast

Like

Centralized management is always great to have and Cisco ACI provides an easy to use interface despite how complex the tool can be. In our enterprise environment, Cisco ACI has scaled well as we have been able to build out security posture in more areas of the network with both physical and virtual systems. Likewise, as we have scaled up it has increased our need to do things more programmatically. We've been able to leverage Terraform scripts with ACI for more standard deployments.

Dislike

I don't really have anything I dislike

Dislike

Very complex to configure a simple task. Experience about instability with L2 bugs (misconfiguration by Advance Services cause subnets flapping but TAC could not resolve it for 3 weeks)

Dislike

Compared to other micro-segmentation products it seems Cisco ACI is more complex and more difficult to learn. This makes it challenging when trying to turn certain responsibilities over to other team members or having new members join the team. The other two items that could use some work are documentation to assist with troubleshooting, as well as better support. Initial deployment was also a major pain and we felt like we didn't get the support from Cisco that we needed at the time.
