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.

Smart configuration management eliminates the need to worry about managing the network's configurations
Based on my experience in the Indian market, there are four to five areas that need improvement. First, there is a lack of marketing and awareness about Juniper, making it difficult to reach end-users and deliver solutions. Second, Juniper's education and awareness centers are costly and not easily accessible like Cisco's resources and their understanding of users' requirements. The information is not easily available on online channels like Youtube. Third, Juniper needs to promote its Mist integration better, and pricing is also a significant factor. Finally, Juniper needs to address the market's specific requirements, such as the SME sector, and offer more lower-priced products like a lower-end segment switch. In summary, improving marketing and sales, education and awareness, Mist integration, pricing, and catering to specific market requirements are areas that need improvement. I just want a good feature in the SD-WAN. Juniper should consider integrating its firewall experience with its SD-WAN devices to create a complete package. With everything moving to the cloud, companies require intelligence and security solutions for their on-prem infrastructure. Moreover, Juniper should integrate its SOC solution into its Mist portal and SD-WAN devices, including IPs, IDS, web and content filters, and messaging. This would provide a complete product and give Juniper an advantage over competitors such as Cisco. I believe that with a bundle that includes SOC and UTM flavors in their Mist portal, Juniper can make a significant impact in the market.

Quotes from Members

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

Pros

"One of the most valuable features is centralized management. The other is the ability to create policies by routing."
"The centralized configuration is its most valuable feature."
"It offers multitenancy. The opportunity to install it on the same platform with a huge amount of customers."
"Cisco solution is a perfect product and considered number one in the world in many parts."
"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."
"It has saved me a couple of times, as just a backup feature. It can easily do a snapshot before you do any change, and if something goes wrong, you can just rollback."
"It has benefited my organization by saving us a lot of time."
"The good thing about ACI is its integration with the different hypervisors, as it supports VMware, Hyper-V, and KVM and can integrate with the virtual environment of Hyper-V, VMware, and KVM very well while its automation also helps deploy and do the integration very easily in the virtual compute part of the network."
"Juniper Contrail Networking is a stable solution."
"It provides proactive alerting in a single dashboard solution."
"After we finished setting Contrail up, it seemed stable enough."
"Contrail automates the excellent communication between virtual appliances."
"After we finished setting Contrail up, it seemed stable enough. Still, we never tested it in a real environment, so we don't have enough information to say whether it's stable with a given number of users and appliances. We have tested it in a lab environment, but we haven't tested enough to say that the platform is stable."
"Juniper Contrail Networking is low-cost for small and medium-sized businesses, and Cisco and Palo Alto solutions are more expensive."
 

Cons

"Our problems with Cisco ACI are mainly related to the contracts and how to manage them easily in the platform. Cisco also needs to improve the log files and the complexity of the graphical interface."
"At first, the setup was really complex because we did everything with the GUI first. We had to figure out how to do that and it was frustrating because we had a lot of errors which didn't really tell us anything because we're used to other kinds of messages from the old school networking."
"The product needs to be simpler. There is too much complexity in ACI. 80 percent of its features are of no use to us. We could do with a simplified version."
"Before version 5, you could manage your firewall or load balancer from the AP. It was very basic and now they removed the whole features in the new version, so you cannot manage your load balance or firewall from your AP on L2, L4, and L7 services."
"I would like for there to be more information about it available. While using the ACI in the graphical interface, I would like if there was something that explained every step that you can click and it will tell you what you are doing in more detail."
"In terms of improvement, I would like to see some sort of way to baseline the system in a network-centric fashion."
"There are many bug fixes required with Cisco ACI."
"It would be nice if I could specify network-centric in my design, and the system would organize and set itself up in that way."
"Concerns were raised about the complexity of involving networking components like MX routers, which often required expertise beyond the scope of software engineers. As a result, users encountered challenges in achieving comprehensive understanding and troubleshooting of networking issues within the Contrail environment."
"Visibility, especially for the top of the platform, is a nightmare. The top was documented incorrectly and really complex to complete. In the end, it worked but only after several weeks of work with the support of a Juniper solution engineer in Holland."
"Juniper Contrail Networking is difficult if you do not have a certificate for Juniper. Juniper is a different type of configuration or operation than Cisco."
"Juniper needs to address the market's specific requirements, such as the SME sector, and offer more lower-priced products like a lower-end segment switch."
 

Pricing and Cost Advice

"The licensing cost for ACI is expensive - I would rate its price 2.5 out of five."
"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."
"This is an expensive solution."
"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."
"Cisco's pricing is very expensive."
"We used Cisco Professional Services for the deployment. They were outstanding, but very expensive."
"The pricing is pretty good for new technology."
"Price is always an issue."
"Juniper Contrail Networking is low-cost for small and medium-sized businesses. Cisco and Palo Alto solutions are more expensive."
"There are many vendors in the wireless market that offer better pricing, solutions, and management skills compared to Juniper."
