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 stability is perfect, and we have had no problems with Cisco ACI."

"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 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."

"The most valuable feature is the data center communication."

"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."

"A lot of our tasks in cloud projects are now done faster than before and we can implement customer requirements more quickly, with our quality improved because we have faster visibility into when faults occur in the network."

"The best part of Cisco ACI is the server deployment and integration."

"It is very stable. It works 100 percent of the time."

More Cisco ACI pros

"Contrail automates the excellent communication between virtual appliances."

"It provides proactive alerting in a single dashboard solution."

"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."

"Juniper Contrail Networking is a stable solution."

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

Cons

"It would be better to introduce some wizards to guide you through the whole configuration process instead of clicking through a bunch of menus with no concrete path. It is too easy to forget one or another if you configure it this way."

"Frequently, customers become discouraged after transitioning from traditional networking due to its complexity, and they struggle with the steep learning curve necessary to appreciate Cisco ACI's capabilities fully."

"Deploying Cisco ACI was a little complex because we needed to add a lot to the fabric. You need to configure some servers, connect everything, make templates, and deploy switches. It takes five people to deploy and maintain."

"There were issues when upgrading venues and registering devices."

"Quality Assurance could be better, and there are a lot of bugs in each release. We discover these bugs when we upgrade the ACI environment, sometimes resulting in downtime. In the next release, I would like to be able to manage hybrid cloud networking. So currently, if you have an ACI environment running on-premise or Epic in the cloud, we can handle it with the NexSys dashboard. But if Cisco can integrate SD WAN-related features, through which we can do multi-cloud networking, that will be an awesome feature. It should be more flexible."

"We had issues in the first deployment when we tried to finish the migration from traditional networking to Cisco ACI."

"Biannually, there is a new design delivered by Cisco. Thus, you are always running behind the new design, and it never stops. With Cisco ACI, this has been a nightmare."

"Cisco is much more expensive than other vendors, especially when it comes to the licensing. For half the cost, I can obtain the same service with another product."

More Cisco ACI cons

"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 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."

"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."

Pricing and Cost Advice

"The cost is fine."

"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."

"The pricing, including both hardware and licenses, is reasonable."

"The price could be improved. It is expensive, but then again, it is Cisco. The price is worth what you pay for."

"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."

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

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

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

More Cisco ACI pricing and cost advice

"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."
