We performed a comparison between Juniper Contrail Networking and VMware NSX based on real PeerSpot user reviews.
Find out what your peers are saying about Cisco, Juniper, Aviatrix and others in Software Defined Networking (SDN)."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 a stable solution."
"Contrail automates the excellent communication between virtual appliances."
"It provides proactive alerting in a single dashboard solution."
"VMware NSX's overlay network is its most valuable feature, as it aligns with any network philosophy and allows for efficient addressing mechanisms. Additionally, the ability to extend the on-premise network into the provider space is beneficial. There are many features provided."
"Their technical support is very good. They help us figure out solutions when we have problems."
"It's very important for them to have small footprints and have as much services in their servers, as possible."
"This is a good firewall and overall it is rich in features."
"The most valuable feature of VMware NSX is the ability to set up virtual networking environments."
"The interface is intuitive enough."
"The ability to scale from different clouds. At the moment, the scalability of the product is the number one thing that I saw."
"The microsegmentation is a good feature. You can segment details, products, or hardware information."
"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."
"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."
"It takes time to do the initial setup. It is a bit slow, which is surprising."
"It was stable for one year, there was no impact. In the last two months, we had two big incidents."
"It lacks full knowledge of physical side of the network topology."
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
"Lacks integration with other solutions."
"Their licensing model should make it easier to purchase licenses."
"They have to work more and more on the integration for public cloud services and have cyber security platform integration."
"We would to have a reverse proxy. This would add great value to the solution."
