AX SERIES: GLOBAL SERVER LOAD BALANCING (GSLB)

Global Server Load Balancing (GSLB) is one of the most popular load balancing technologies today. A10's GSLB functionality is a key differentiator in the high-performance and highly scalable AX Series due to seamless implementation and exceptional value. Key A10 GSLB benefits include:

Provides data center failover and continuity
Optimizes multi-site deployments
Ensures users' Web experience is the fastest
Included in all AX Series models with no additional charge

A10's GSLB functionality extends load balancing to a global geographic scale by using a DNS proxy method. A10's GSLB adds another layer of High Availability and performance to applications with minimal impact to existing DNS architecture.

DNS Proxy technology
Continue to use existing DNS infrastructure without changing DNS server configuration
No need to create or delegate sub domains, existing DNS maintains control

GSLB functionality for applications can be leveraged through existing AX Series deployments, combining load balancing and GSLB on a single box, or separately by running GSLB on its own dedicated AX Series platform. All AX devices participating in GSLB and local server load balancing communicate with each other and share the overall health information of the datacenter and applications.

By adding intelligence to DNS, application load based on several new factors:

Disaster recovery
Provide an extra level of High Availability to important applications
Direct requests based on availability or health of the application

Active RTT
Send client connections to the fastest responding datacenter
Based on ping or DNS response time

Geo-location
Send client connections to the "closest" physical datacenter
Integrate with geo-location services using any CSV format

Session capacity
Send client connections to the data center with the most available remaining capacity

Weighted values
Send client connections to the data center that has the highest combined score
Send client connections to the data center with the most available active servers
