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

"I rate Cisco ACI nine out of ten due to its impressive features."
"The best part of Cisco ACI is the server deployment and integration."
"Automation features have been most beneficial for managing complex networks."
"It decreases network provisioning time and application provisioning time, and it also takes fewer resources to manage it because you have a centralized system where one APIC controller can manage more than 200 leaf switches."
"The best part of ACI is that it can integrate with a lot of virtual environments like VMware, Hyper-V, and KVM."
"It improved the speed of the daily business, and with the preconfigured workflows, daily business tasks are now done more quickly than in the past."
"The biggest benefit has been that it has improved communication between my endpoints in the data center."
"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."
"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."
"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

"I think that technical support tickets should be escalated sooner."
"Cost is one thing that could be improved, as it is heavy for an emerging market like ours."
"Cisco needs to enhance their technical support and pay more attention to regional support."
"I would like to see a smoother transition from existing systems."
"Cisco ACI is a highly complex solution. The initial deployment is just a few clicks, but understanding how an ACI works and interacts with routing, switching, and virtualization takes a lot of knowledge. The interface isn't necessarily hard to use, but the technology is complicated. If you want to understand how it works and how to configure it, you should study hard."
"We have had two calls with technical support. They are not the best. We opened a case to diagnose issues and it's taken weeks to get someone on the case and to move forward."
"The product needs to be simpler. There is too much complexity in ACI. 80 percent of its features are of no use to us. We could do with a simplified version."
"One of the things that makes it a lot more complicated is the way contracts are handled in ACI. Contracts are like their own access lists. They can improve the setting up of contracts between devices a lot. It can be simplified."
"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 good thing about Cisco is that you can trade in your old products to replace them with ACI."
"Price is always an issue."
"It is quite expensive. It is not at all on the cheap or medium side."
"There are no additional costs. We only have to pay for a support contract apart from the license."
"I don't believe there is any licensing required."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"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."
"We have seen time improvement using the product."
"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."
