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 efficiency in terms of the data center latency has been reduced by around 20-30%. Our applications function a lot better. We get a lot of intuitive data to know how our application stack is performing."
"The straightforward migration of all of the applications and loop balancing are the two most valuable features. Also, the measurement of their customer-wide sources is very straightforward. It's another dimension of the networks."
"Automation features have been most beneficial for managing complex networks."
"Automation is its most valuable feature."
"Cisco solution is a perfect product and considered number one in the world in many parts."
"The most valuable feature is the throughput that it offers."
"ACI's most valuable feature is its SDN capabilities. Everything is on your software design controller. Everything is blocked by default until you allow it."
"The scalability is very good, as the controller automatically detects new additions and scales itself, and it's agile because it's a cloud-based network."
"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."
"This solution is a bot management tool that provides extensive capabilities for Cloud Armor."
 

Cons

"We deployed a lot of Fabrics to multiple sites, which was a bit complex."
"They should improve the GUI, make it simpler. They also need to improve its integration with other automation tools."
"I have been a bit disappointed with technical support from Cisco. They will often take some time to respond."
"The initial setup was a bit complex."
"Operationally complex without a Cloud Management Platform to push policy, which is true for any network virtualisation solution."
"Better troubleshooting features would be helpful. In ACI, it can be a big mess, a real headache to troubleshoot a single issue... The troubleshooting part, and the information that ACI gives you, sometimes don't give you a proper, inside picture of what's going on within the fabric."
"It is challenging for people who don't understand the programming language, making it difficult to migrate. With technology, there are two verticals. One is hardware driven and the other is software driven. Most people in our domain understand networking, but they don't understand programming. When we migrate, some programming is required."
"I wish that if I had to open up an additional tab, I wouldn't have to log in every single time."
"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 pricing, including both hardware and licenses, is reasonable."
"There are no additional costs. We only have to pay for a support contract apart from the license."
"Once you sign for the start kit implementation, you have to go all the way through to the implementation, even if you are experiences issues."
"The cost is fine."
"The good thing about Cisco is that you can trade in your old products to replace them with ACI."
"I don't believe there is any licensing required."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"Price is always an issue."
"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."
