Handles network connections and hosts multiple services with automation

Juniper Contrail Networking is designed to streamline and integrate networking solutions within OpenStack environments. While Juniper's strategy initially aimed at enhancing system integration, some users have reported challenges with seamless integration, with other platforms like Red Hat and Ubuntu. These integration issues sometimes led to difficulties in diagnosing problems, as they were attributed to Contrail or OpenStack rather than directed to the appropriate support channels. Additionally, 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.

Has improved network visibility and security through micro-segmentation and SDN capabilities

This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

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."

"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."

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

"Juniper Contrail Networking is a stable solution."

"The Distributed firewall is simple to add to the network and rules are easy to implement."

"The most valuable features for us at this early stage are the interface and the integration with existing VMware solutions."

"Their technical support is very good. They help us figure out solutions when we have problems."

"The product has valuable features for security and network extension."

"It has reduced the number of people on the network team along with the system engineer involved in the security process. So, it is valuable."

"The stability is great. That's one of the things that we can quantify and leverage through NSX, because it's less complex. We have the availability to manage multiple things at the same time. You can identify problems before they manifest."

"One significant advantage of VMware NSX is the ability to provide advanced security at the micro-level, focusing on securing applications and workloads rather than just the network structure or virtualization-based network security."

"You're building a scalable solution, a secure solution, and a stable end-to-end solution; these are the main measurable benefits VMware NSX provides to the users."

Cons

"Visibility, especially for the top of the platform, is a nightmare. The top was documented incorrectly and really complex to complete."

"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."

"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."

"It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it."

"It lacks standard security features, which is why I rate it so low."

"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."

"Its licensing model could be VM based."

"There are sometimes mismatch in the control, the details and what you actually see on the transport note."

"Any technical product has its own limitations in one place or another."

"I would like them to make integration with other vendors easier."

"The engineering team has room for improvement. They should have more of a Knowledge Base about different case studies and should develop more advanced features."

More VMware NSX cons

Pricing and Cost Advice

"There are many vendors in the wireless market that offer better pricing, solutions, and management skills compared to Juniper."

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

"The subscription is on a yearly basis."

"VMware NSX isn't cheap."

"I was not involved in the purchase of the solution but I hear it is on the expensive side."

"The price is based on the virtual desktop infrastructure(VDI) side and also is dependant on the size of the environment. The price is expensive and it could attract more purchasers in smaller organisations if it was reduced."

"There is a license required for this solution and there is also a support license available. The price of the solution could be better."

"If five is a good price and one is a high price, I would rate the price a one out of five."

"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."

"The licensing fees are expensive and we pay on a yearly basis."
