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

"In legacy networks, managing changes requires individual tickets for each device. ACI's single pane of glass management through APIC is a big advantage. So, single-tenant management is a plus."
"It scales very well. When you increasingly scale with it, it makes the product easier to work with."
"The operation and maintenance costs have been reduced. It is also simple to deploy any deployment. Any configuration can be easily done."
"It is very stable. It works 100 percent of the time."
"This solution is easy to configure, and it is done in an object-oriented manner."
"The most valuable features are the automation with the different systems for the software development and the ability to provision switches in hours rather than days."
"We get a full holistic view of the ecosystem."
"The scalability is great. This is the greatest feature of the technology. It is a great improvement in scaling out. It can greatly increase the overall scalability of the Fabric with multi-port and multi side, making it a great product."
"Juniper Contrail Networking is a stable solution."
"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."
 

Cons

"Our problems with Cisco ACI are mainly related to the contracts and how to manage them easily in the platform. Cisco also needs to improve the log files and the complexity of the graphical interface."
"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."
"The challenging thing about Cisco ACI was we had to put a lot of effort into providing the customer the full picture, new standards, and new technology that they had to use. This was more challenging than deploying the product."
"Technical support needs to be more helpful. It's rare that you get a knowledgeable person."
"For Multipod we need Layer 3 devices that support multicast. Customers ask: "Why can't ACI do that? Why do we need a dedicated Layer 3 device for this?" If they go for Multi-Site there is no need for that, ACI can do it. So Cisco needs to increase the Multipod features in ACI."
"Cisco needs to enhance their technical support and pay more attention to regional support."
"If I lose the connection from one side to the core, I can't use the other side to go to the core. I hope in the future, this will be fixed."
"The tool's initial deployment is complex and takes five hours to complete."
"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."
"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."
 

Pricing and Cost Advice

"Price is always an issue."
"A big company can automate it themselves or spend a lot of money and buy it."
"The product is not cheap."
"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."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"There are no additional costs. We only have to pay for a support contract apart from the license."
"We used Cisco Professional Services for the deployment. They were outstanding, but 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."
