Nimit Puvar - PeerSpot reviewer
A VP Enterprise Sales at Ashtech Infotech (India) Pvt.Ltd.
Automation and visibility have simplified data center operations and improved network control
I see some areas for improvement, particularly with pricing. I think that not all features that are needed are already in Arista. AI power is required nowadays. AI would be needed for understanding data traffic flowing in my network. Sometimes I have a vision of what data traffic is flowing in my network and I want to capture that data. Using AI, I can understand how my entire organization operates and what kind of applications are being used, what the peak times are, where there is a bottleneck if any exists. This kind of report should automatically generate and provide clear-cut visibility.
TAIYAB HASAN - PeerSpot reviewer
Windows Redhat Linux Vmware & Azure & Cloud & Nutanix Ahv-Vmware & Backup Senior System Administrator at AlDawaa Medical Services
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.
