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.

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

"Having a lot of racks and switches with a single point of configuration which can be done with automation on one platform using one API. This makes everything work faster."
"I use Cisco for security and collaborating, and I use this solution with WebEx, WebEx Teams, and WebEx Board as a hybrid solution."
"The integration with vCenter means that when I create something on the network, it only has to happen one time instead of many times for our many virtual hosts."
"We are doing automation from ACI and we have integration with Azure. With the Azure stack integration we can have total automation. We can configure the EPGs from there, and we can configure load balancing functionalities from there as well. The most useful feature is that you don't need to configure anything on ACI itself. You can configure on Azure and it will provision your application."
"The most valuable features of Cisco ACI are micro-segmentation, the VXLAN, and the ACI flattening services."
"I like features like policy control and micro-segmentation."
"The centralized management of the entire network data center, in this case with ACI, is the most valuable feature. By having access to some powerful APIs you can build your own tool to speak to the ACI controller, then with that, you can deploy things really fast. Having the option to build your own tools and then using the centralized management of the ACI to push the configuration to the network devices is very valuable."
"We have been able to deploy new applications more efficiently and faster."
"After we finished setting Contrail up, it seemed stable enough."
"It provides proactive alerting in a single dashboard solution."
"Juniper Contrail Networking is low-cost for small and medium-sized businesses, and Cisco and Palo Alto solutions are more expensive."
"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."
"Contrail automates the excellent communication between virtual appliances."
"Juniper Contrail Networking is a stable solution."
 

Cons

"We deployed a lot of Fabrics to multiple sites, which was a bit complex."
"I believe there's room for improvement in terms of ACI's integration with various technologies."
"Security and isolation based on the type of traffic"
"Its graphical user interface (GUI) is not as user-friendly as it could be."
"ACI is not simple by any stretch of the imagination, but the initial go-at-it is pretty straightforward, which is nice."
"For the licensing model of the system, I still have not gotten another update after eight months."
"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."
"The user interface should be made easier."
"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."
"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."
"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."
 

Pricing and Cost Advice

"The licensing cost for ACI is expensive - I would rate its price 2.5 out of five."
"The pricing is pretty good for new technology."
"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 cost is fine."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"Pricing for Cisco ACI could be expensive if you're not a gold partner. If you're a gold partner, you'll get reasonable pricing, but to become a gold partner, you must cross several layers. For example, at least twenty engineers within your organization have to be certified, with each certification priced at £2,000 minimum, so this would make some companies think twice about the product. If you're going for Aruba and Juniper products, on the other hand, you can quickly get the partner status, and you can start selling the product. As a gold partner, you can get up to seventy percent discount on Cisco ACI, for example, while an ordinary partner gets ten percent off. Cisco ACI is expensive for both customers and partners, but I'm rating pricing for the product as four out of five because even if the price is costly, you get a lot of benefits from the product. Cisco ACI isn't the best, price-wise, but it's still a good solution. If you're in a small organization, you may be unable to afford it. Cisco ACI is best for enterprises but not SMBs because Cisco ACI and its required resources are expensive."
"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."
"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."
