Global Traffic Manager
Route Traffic to the Right Region at the DNS Layer
TR7 GTM turns authoritative DNS into a live traffic-decision engine. User requests are routed to the right data center, the right region, or the right healthy target based on geography, latency, service health, and traffic policy — without depending on a cloud service, on your own infrastructure.
Right Region. Healthy Service. Uninterrupted Access.
DNS no longer just returns records; it decides where traffic should go. TR7 GTM evaluates health, user location, network latency, and distribution policy together to produce every response based on live conditions. Control stays in your infrastructure; the decision engine isn't handed off to the cloud.
Turn DNS Into a Traffic-Decision Layer
Traditional DNS maps names to IP addresses. TR7 GTM produces every DNS response based on live service health, user location, network latency, and traffic policy. Users are routed to the right region, the healthy service, and the most suitable target.
On failure, traffic shifts automatically to the healthy location. Gradual rollouts — moving traffic to a new service in controlled ratios — blue/green releases — running old and new environments in parallel for a safe transition — and A/B distribution — splitting traffic across targets by ratio — are all managed at the DNS layer.
TR7 GTM applies these decisions without handing off to a cloud-based service — in your own infrastructure, integrated with ADC health checks. DNS is no longer a static record system; it is a live routing layer running on health, performance, and policy signals.
Five Ways to Route Traffic to the Right Target
Not every application needs the same routing decision. TR7 GTM lets you use different routing modes per record, per zone, or per service — and combine them within the same policy when needed.
Geographic routing
Route users to the right data center by country, region, or continent. European traffic to the EU region, Asian traffic to APAC, LATAM traffic to the local data center — without extra client-side logic.
Latency-based routing
Route the user not just to the nearest region but to the target responding fastest right now. Network latency and performance signals are evaluated; the fastest path for the user is chosen.
Weighted DNS
Distribute traffic across targets in the ratios you define. Roll out new services gradually, run A/B distribution, or manage blue/green transitions at the DNS layer in a controlled way.
Health-based failover
When a region or service becomes unhealthy, DNS responses automatically shift to the healthy target. The decision rests on integrated health checks rather than an external monitoring service.
Bidirectional failover scenarios
Define separate rules for switching from primary to backup and switching back. Run fast switch-over, controlled return, manual approval, or automatic recovery scenarios per policy.
Authoritative DNS Designed for Operators
TR7 GTM doesn't just host DNS records; it consolidates enterprise DNS operations on a single platform with zone management, advanced record support, multi-step health scenarios, trigger-based response logic, DNSSEC, and express zone serving.
DNS record management
Broad record support including A, AAAA, CNAME, MX, TXT, SRV, NS, CAA, and DNSSEC records. Fine-grained control at zone, data center, and record level.
Health-check scenarios
Make decisions based on real service logic, not on a single ping result: API and database must be up together, at least one of the alternate paths must work, or a given service chain must stay healthy.
Active health monitoring
Zones, data center targets, and service pools are continuously monitored. DNS responses update automatically as health status changes.
DNS forwarders
When some zones are hosted on TR7 and others elsewhere, forward queries to the right destination by suffix, view, or policy.
Triggers
Automatically change DNS responses when a service becomes unhealthy, a maintenance window opens, or a specific event happens — without operator intervention.
Expression FX rules
Define conditional logic that influences DNS responses — without writing scripts. TR7's rule engine works at the GTM layer with the same operator experience.
Express zone acceleration
Pull zones from the authoritative master via AXFR, IXFR, and NOTIFY; serve them in-memory at high performance. The master DNS stays hidden while GTM absorbs the public query load.
Multi-source data center selection
Don't leave the data center decision to geography alone. Host metrics, service health, connection count, bandwidth, hops, packet loss, and client-side signals can all be evaluated together.
On-prem DNSSEC
Sign authoritative zones in your own infrastructure. DNSKEY, DS, NSEC3, RRSIG, and CDS records are supported; key control stays with the operator.
GTM Picks the Region, ADC Distributes Within the Region
When global routing and intra-region distribution run on the same platform, health data, service inventory, and operator experience are shared. TR7 GTM works integrated with the backend-service pools and health checks ADC uses.
Live health signal from ADC to GTM
When an ADC backend becomes unhealthy, GTM doesn't try to rediscover it; it shares the same health information. DNS responses remove the affected data center from the answer set and users are routed to healthy targets.
DetailsSame operator UI, same service definitions
GTM data center entries can reference the same backend-service pool definitions ADC uses. No duplicated inventory, no separate health endpoints, no two parallel management disciplines.
DetailsRouting Decides Where. The Rest of the Platform Manages How.
TR7 GTM routes traffic to the right region. TR7 ADC publishes the application and distributes it within the region. TR7 WAAP protects it. TR7 AAM decides who can reach it. Four products on one platform, one operator UI — working together.
- Backend resources: services, certificates, and health checks
- Reports and logs
- Users and RBAC
- Multi-tenancy
Each pillar is an independently licensable product; but they share the same operator UI, the same service-pool definitions, the same certificate store, and the same reporting plane. That's why running the products together takes minutes, not weeks.
