Radware Alteon

What is Radware Alteon?

Radware Alteon is an Application Delivery Controller (ADC) - a device for managing application traffic: load balancing, SSL offloading, acceleration. It ensures high availability and performance of applications.

Main functions:

• Load Balancing - distributing traffic among servers
• SSL Offloading - offloading servers from cryptography
• GSLB - Global Server Load Balancing for multi-DC
• Application Acceleration - compression, caching, TCP optimization

Typical problems:

• Single-server application = single point of failure
• Servers overloaded with SSL handshake
• Slow applications (no compression, TCP optimization)
• Multi-DC without automatic failover
• No visibility into application traffic

Key Features

Load Balancing Algorithms

Algorithm	Description	Use Case
Round Robin	Even distribution	Equal servers
Weighted Round Robin	With weights	Different server power
Least Connections	Fewest connections	Long-lived connections
Response Time	Fastest server	Performance-critical
Hash (IP/URL)	Sticky sessions	Stateful apps

SSL Offloading

Offloading servers from cryptography:

    style D fill:#22c55e,stroke:#16a34a,color:#fff

Benefits:

• Servers don’t perform SSL handshake
• Centralized certificate management
• Hardware acceleration for TLS
• Traffic inspection (WAF, IDS)

FAQ

How is it different from nginx/HAProxy? Alteon is an enterprise ADC with hardware SSL acceleration, GSLB, advanced health checks, unified management. nginx/HAProxy are software LB for simpler use cases.

How does HA work? Active-Active or Active-Standby. Automatic failover with session persistence (state sync between units).

What is VIP? Virtual IP - address that clients see. Alteon redirects traffic from VIP to backend server pool.

Can I use with DefensePro? Yes. DefensePro before Alteon for DDoS protection, or Alteon with AppWall for WAF.

How is it licensed? Per throughput or per feature. You can start with base and add modules.

Does nFlo deploy Alteon? Yes. On-prem and cloud deployments, LB configuration, SSL offloading, GSLB, security stack integration.
