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.

Bot management tool enhances defense capabilities against DDoS and SQL injections
This solution is a bot management tool that provides extensive capabilities for Cloud Armor. It helps with DDoS defense and OWASP for SQL injections and cross-site scripting. We can rewrite these rule sets for DDoS protection. Integration with Cisco WAF is possible. It is scalable and integrates with Google's Kubernetes for easier scaling processes. It includes AI features like auditing and logging for troubleshooting.

Quotes from Members

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

Pros

"The product works very well with our virtual environment."
"The most valuable features of Cisco ACI are micro-segmentation, the VXLAN, and the ACI flattening services."
"The initial setup was trivially simple and easy. It builds itself because it is automation. You don't have to do too much."
"The best part of ACI is that it can integrate with a lot of virtual environments like VMware, Hyper-V, and KVM."
"It improves security and automation; it is stable and provides flexibility with different workloads, and it is also more powerful from a security point of view."
"The most valuable feature is the data center communication."
"We can support policy based on our intent, then that gets rendered into the policy that we will be using for Fabric."
"It improves security and automation."
"This solution is a bot management tool that provides extensive capabilities for Cloud Armor."
"We utilize Google Cloud Armor alongside our Cloud Load Balancer to safeguard against DDoS attacks. This setup acts as a local Layer 7 proxy provided by Google, allowing us to predict and mitigate DDoS threats effectively."
"It helps with DDoS defense and OWASP for SQL injections and cross-site scripting."
 

Cons

"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."
"There have been challenges with the technical support. Though, the product is almost three to four-years-old, there are still things that only a few people can solve."
"Cisco support used to be good, but over time, many newbies were hired to provide technical support for Cisco ACI and other Cisco products, so the quality has decreased."
"One of the things that makes it a lot more complicated is the way contracts are handled in ACI. Contracts are like their own access lists. They can improve the setting up of contracts between devices a lot. It can be simplified."
"ACI is not simple by any stretch of the imagination, but the initial go-at-it is pretty straightforward, which is nice."
"There are many bug fixes required with Cisco ACI."
"I would like to see a lot more integrations with the rest of the Cisco portfolio."
"It is more about resolving bugs early on in the code. Otherwise, as the product gets more mature and those bugs get discovered sometimes by the customer, then Cisco will resolve them."
"There are some discrepancies within billing, which makes the product average."
"I believe Google Cloud Armor can benefit from enhancements of AI and automation."
 

Pricing and Cost Advice

"The price could be improved. It is expensive, but then again, it is Cisco. The price is worth what you pay for."
"We bought a package for hardware, software, and support. At that time, Cisco was simply selling that package to distributors, then we opted for it directly."
"It saves time and resources."
"The licensing cost for ACI is expensive - I would rate its price 2.5 out of five."
"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 good thing about Cisco is that you can trade in your old products to replace them with ACI."
"It's expensive but the product is very good. I have never found another partner like Cisco with a solution like this and with great support."
"We used Cisco Professional Services for the deployment. They were outstanding, but very expensive."
"I would rate the pricing of Google Cloud Armor around 7 on a scale of 10. As for the licensing costs, I'm not directly involved in billing, so I don't have specific details on that aspect. We have a partner agreement with Google, which gives us a discounted price for using Cloud Armor."
