Enables streamlined data center management with automation and application-centric design
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. That's helpful, and it's good for one-time implementation. The automation capabilities are really helpful. We deployed one data center using Terraform, and after deployment, many automation features are available, which can be very helpful. Based on my experience, Cisco ACI provides substantial capability; you can design your network accordingly and it's part of the SDN family, providing many benefits to the organization, especially when moving from traditional network infrastructure. Many organizations are actually using the old traditional Nexus infrastructure or some old data center devices. It gives you significant control and one-time implementation capabilities, and it also provides better performance and security. Functionality-wise, Cisco ACI provides integration using automation. We implemented it through Terraform, which was easy. Those features are available, so I don't think any new features are needed right now; something new could come up, but they have implemented many improvements over the years.

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 previous generation of networking, everything was slow, taking days to deploy and run a script, but with Cisco ACI, I can deploy things with a script, then run it in five minutes."
"Instead of taking days or multiple days for a deployment of a server or application, they can do it immediately within minutes because all the configuration templates are already there in the control plane, which we can push immediately when the new server gets added."
"With its programmability, you can do stuff to policies to make them more flexible, allowing you to connect devices in new ways."
"It has benefited my organization by saving us a lot of time."
"We are service providers; it has allowed us to serve some of our outsourced customers better than the previous generation of products."
"Virtualization and integration with VMware is the most valuable feature."
"We can support multiple VDRs of multiple branch offices at same physical location in the same infrastructure."
"Once we have it running, it should be easier for us to program our IT rather than going case-by-case, by switches and different elements, or program it by hand."
"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."
"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

"More how-to videos and instructional information is required."
"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."
"It needs to be able to function on the cloud."
"In the new version of 4.0, the management groups for updating the software is not the best way to do it. It was better in 3.2."
"There is quite a learning curve at the beginning."
"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."
"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."
"I think that technical support tickets should be escalated sooner."
"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."
"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."
"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 pricing is pretty good for new technology."
"Cisco is much more expensive than other vendors, especially when it comes to the licensing."
"It is quite expensive. It is not at all on the cheap or medium side."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"If you compare the licensing and total cost of ACI, it's cheaper than NSX because of the licensing fees. If you are going for full NSX features it will be too expensive, especially the next-generation firewalling feature."
"We used Cisco Professional Services for the deployment. They were outstanding, but very 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."
"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."
"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."
