NetScaler and VMware Avi Load Balancer are competing products in the application delivery controller category. NetScaler seems to have the upper hand due to its extensive range of features and integration capabilities, although VMware Avi Load Balancer is noted for its user-friendly interface and analytical power.
Features: NetScaler offers features such as load balancing, SSL offloading, increased security with a web application firewall, and high availability setups. Its all-in-one solution is designed for environments needing comprehensive management. VMware Avi Load Balancer focuses on load balancing and web application firewalling, with powerful analytics and an intuitive interface across multiple platforms.
Room for Improvement: NetScaler users highlight challenges with its configuration process and frequent software bugs. Multi-tenancy and scaling are also areas needing improvement, alongside the high cost and complex licensing. VMware Avi Load Balancer users seek improved documentation and better interoperability with third-party systems, along with enhanced security features and simpler cloud integration.
Ease of Deployment and Customer Service: NetScaler can be deployed on-premises or across various cloud models, though the deployment process often requires experienced personnel. Customer support receives mixed reviews, with consistency in response being a noted issue. VMware Avi offers flexible deployment across varied cloud infrastructures with generally positive reviews about its responsive technical support, although some users mention it could improve further.
Pricing and ROI: NetScaler is often deemed costly, justified by its robust feature set. Users point out the complex licensing but recognize the strong return on investment given its security and application delivery enhancements. VMware Avi Load Balancer is more competitively priced with flexible licensing models based on usage, providing solid value especially in facilitating efficient data center operations.
VMWare Avi Load Balancer has created a smoother failover process without issues, keeping the state normal, where typically there would be manual intervention.
I have not found any return on investment so far, as it does not really lend itself to that; it is more about not having to stand up another data center for redundancy.
The solution architect from VMware side told me that there would be no issue adding them. Here we are with an RFP, and we cannot add them easily.
They are quite responsive, taking the necessary time to address our issues.
The support for VMWare Avi Load Balancer is really good, and the integration with other tools is really effective, which makes the overall experience smoother.
I would rate the scalability of VMWare Avi Load Balancer a perfect ten out of ten because it senses traffic and scales automatically, also scaling down when there is no need, making it very elastic, resulting in zero costs when there is no traffic, which is excellent.
In my role as a database engineer, scalability works in two layers and rarely becomes a bottleneck.
Scalability-wise, VMWare Avi Load Balancer is good.
VMWare Avi Load Balancer is stable based on my experience.
VMWare Avi Load Balancer is very reliable and stable.
From a stability point of view, VMWare Avi Load Balancer is stable.
Multi-cloud capability comes from a configuration called NSX Extended.
The need for policy execution tracing to simplify debugging is evident because if connections are routed incorrectly, for example, directly to a replica, debugging can become painful in production.
It would also be beneficial to have true VMWare Avi Load Balancer failover at the VMWare Avi Load Balancer level.
The experience with pricing, setup cost, and licensing shows that its pricing is quite pricier compared to Anthos Service Mesh.
it operates on a capacity and consumption model, unlike traditional appliances that charge based on hardware.
VMWare Avi Load Balancer positively impacts my organization by including a web application firewall, DDoS protection, and bot mitigation, which are great security features.
The special capability I appreciate about VMWare Avi Load Balancer is its ease of use; it is very lightweight and quite inexpensive to deploy.
It is much cheaper than F5 load balancers and other load balancer products out there.
