What is Edgenexus Global Server Load Balancer (GSLB)
Edgenexus Global Server Load Balancer (GSLB) is a DNS-based global load balancing product used to distribute application traffic across multiple data centers or cloud regions. It targets IT and network teams that need high availability, disaster recovery routing, and geo- or policy-based traffic steering for internet-facing services. The product typically combines health checks with configurable routing policies to direct users to the most appropriate endpoint and to fail over when an endpoint becomes unavailable.
DNS-based global traffic steering
The product focuses on global load balancing by answering DNS queries with different endpoints based on policy. This approach works across heterogeneous environments (multiple sites, clouds, and hosting providers) without requiring an in-path proxy for all traffic. It fits use cases such as active-active distribution and active-passive failover between regions.
Health checks and failover
GSLB implementations commonly include continuous monitoring of endpoints and automated failover when checks fail. This supports disaster recovery patterns where a standby site should receive traffic only when the primary is unhealthy. It can reduce manual intervention during outages compared with static DNS records.
Policy-driven routing options
Global load balancers typically provide routing policies such as geographic steering, weighted distribution, and priority-based failover. These controls help teams manage latency, regional capacity, and maintenance windows by shifting traffic intentionally. It is useful when different applications require different routing behaviors under the same domain portfolio.
DNS caching limits control
Because routing occurs at DNS resolution time, client and resolver caching can delay traffic shifts even after a health state changes. This can make failover behavior less immediate than in-path load balancing. Achieving faster convergence often requires careful TTL tuning, which can increase DNS query volume.
Not an application proxy
A DNS-based GSLB does not provide L7 proxy features such as request-level routing, header-based rules, or per-request retries. Teams typically still need local load balancers or ingress controllers at each site for application-layer controls. This adds architectural components and operational overhead.
Vendor details hard to verify
Publicly verifiable corporate information for the Edgenexus brand (ownership, headquarters, and official social profiles) is not consistently available from authoritative sources. This can complicate vendor due diligence, procurement validation, and long-term support assessment. Buyers may need to confirm the legal entity, support terms, and product lifecycle directly with the seller.
