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

"This product improved the way our company functions by enabling us to establish our goal of moving to a zero-trust model. That's how Cisco ACI helps us the most."

"PBR has been beneficial for network efficiency."

"Virtualization and integration with VMware is the most valuable feature."

"This solution allows you to do everything quicker and more efficiently."

"It is a complete re-write of everything that you've ever thought of from a networking standpoint, and it can simplify your life if you do it right."

"We work with Cisco because they have many possibilities to work with very good support."

"The scalability is perfect, and it is one of the main reasons that we install it."

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

More Cisco ACI pros

"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."

"Juniper Contrail Networking is a stable solution."

"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."

"After we finished setting Contrail up, it seemed stable enough."

Cons

"The integration has room for improvement."

"The GUI is not easy to use."

"Compared to VMware, it needs more virtualization technologies."

"The initial setup was fairly complex and it looks terrifying when you first log in."

"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."

"The additional features I would like to see included in the next releases are support for our policy-based routing. There are endpoint issues that are there now in the code. Hopefully, these will get fixed in the future code."

"The interface is sometimes slow. I receive a lot of weird errors when I try to install apps, such as contract apps, which should give me a nice visualization of all the contracts. However, it just doesn't load, etc."

"The way the objects are oriented on it are not as straightforward as they should be. The learning curve of this product is very steep."

More Cisco ACI cons

"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."

"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."

"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."

"It is quite expensive. It is not at all on the cheap or medium side."

"Price is always an issue."

"Cisco's pricing is very expensive."

"We used Cisco Professional Services for the deployment. They were outstanding, but very expensive."

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

"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."

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."
