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

"The basic functionality that is the most useful is creating a virtual network on a physical device."

"The most valuable feature is programmability, where we can manage a network via APIs and software, as opposed to having to manage complex hardware."

"The most valuable features include microsegmentation, L3 Out features, and the common tenant and tenancy model."

"Cisco support is way better than the competition in my experience."

"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."

"One significant attraction for clients in Iran is the robustness of multicast solutions, which has been a major driver for them to migrate to Cisco ACI."

"The ability to integrate with other systems is the most valuable feature."

"The main features of Cisco ACI that I really appreciate are the application-centric and network-centric designs, allowing you to create your network according to your application."

More Cisco ACI pros

"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."

"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."

Cons

"Sometimes, it has been a bit hard to configure it. Since it is a new technology, Cisco moved all the menus. This made it tricky to use."

"Cisco ACI is difficult both technically to build it out and then operationally to manage."

"The only drawback that we are seeing is the user interface is still a little complex and difficult to use. It needs a more user-friendly interface."

"For the licensing model of the system, I still have not gotten another update after eight months."

"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."

"It could benefit from an orchestration tool that makes deploying services easier."

"We are looking at better synchronization with the cloud and on-premise, bringing in a multi-cloud networking solution."

"I would like to see a lot more integrations with the rest of the Cisco portfolio."

More Cisco ACI cons

"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."

"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."

"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."

"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

"Yearly, we pay around one point two million for the solution."

"Cisco ACI costs depend on how many sites you have. One simple site with a simple installation, including two leaves, two spines, and some fibers, would cost $200,000 to $300,000 for the licenses. The solution is a bit expensive, but it's a good investment if you want your data centers to work without interruption."

"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."

"It saves time and resources."

"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."

"I don't believe there is any licensing required."

"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."

"The cost is fine."

More Cisco ACI pricing and cost advice

"There are many vendors in the wireless market that offer better pricing, solutions, and management skills compared to Juniper."

"Juniper Contrail Networking is low-cost for small and medium-sized businesses. Cisco and Palo Alto solutions are more expensive."
