Provides scalability, ease of migration for future DC moves, multi-tenancy and programmability
Cisco's MSO (Multi-Site Orchestrator) or NDO has room for improvement. Cisco monitors ACI through a product called NDI. I find it very frustrating that Cisco has multiple monitoring platforms. It has DNAC for monitoring Cisco NX-OS, campus switches, and any other routers and switches you would have in the environment. That same thing does not work for Cisco ACI monitoring. MEraki cloudbasd platform for Meraki which will get extended to Campus monitoring, to be honest Cisco never got Monitoring 100% right from days of CiscoWorks to Prime to current platforms. To monitor and manage Cisco ACI, you need to have another platform called NDI and Cisco Dashboard Insights. What frustrates me about Cisco is that it never has a central, single pane of glass platform for all its solutions. It has one thing for Cisco ACI and another thing for campus switches. I would really appreciate it if Cisco came up with something centralized to monitor everything. I haven't thought about anything since the Cisco NDO is quite advanced, and you can deploy your cloud networking through it. I don't know how many people use it. I might explore it as my cloud orchestration tool in the future. We do a lot of cloud automation using our scripts like TerraForm, but I would like to see people using NDO more. We could have more case studies on how many people use NDO for their cloud orchestration. That might be a much easier journey for people when they move from an on-premises data center into a cloud and move from one cloud to another cloud. That is where I personally see an orchestrator being effectively used for multiple deployments.

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

"I have found the SDN features to be the most valuable."
"All the features provided by Cisco ACI including orchestration to layer seven, service training, load enhancements and firewalls."
"Automation is its most valuable feature."
"With its programmability, you can do stuff to policies to make them more flexible, allowing you to connect devices in new ways."
"I recommend Cisco ACI due to its reliable tech support, timely updates for security, traffic management, and ease of management."
"With Cisco ACI, I can deploy things with a script, then run it in five minutes."
"The most important aspect of Cisco ACI in my opinion is the ease of management. Other solutions, like traditional solutions and pricier solutions—or even fabric and PAT—you have to do many configurations on a box-to-box basis, With Cisco ACI, you go on the AP and do some "next, next finish" installer."
"The most valuable features of Cisco ACI are micro-segmentation, the VXLAN, and the ACI flattening services."
"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."
"Contrail automates the excellent communication between virtual appliances."
"Juniper Contrail Networking is a stable solution."
 

Cons

"The integration has room for improvement. There should be a drag-and-drop interface for configuring the integration where you connect some arrows to boxes, and the system takes care of the configuration. Right now, they have something similar, but it's limited. You have to take care of some things yourself. That is one area that the solution can work on. It's easy now, but it's much easier in other solutions."
"We deployed a lot of Fabrics to multiple sites, which was a bit complex."
"I would like to see a lot more integrations with the rest of the Cisco portfolio."
"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."
"Since it is a new technology, Cisco moved all the menus. This made it tricky to use."
"I think that technical support tickets should be escalated sooner."
"The ACI user interface is complex and Cisco should improve it."
"It is still not mature and has room to grow. As with any product out there, it requires time to develop."
"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 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

"It is quite expensive. It is not at all on the cheap or medium side."
"I don't believe there is any licensing required."
"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."
"Yearly, we pay around one point two million for the solution."
"Price is always an issue."
"The licensing cost for ACI is expensive - I would rate its price 2.5 out of five."
"We don't use all of the features but it's still worth the money."
"Cisco's pricing is very expensive."
"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."
