Multi-Region Application Delivery and Routing
Multi-region enterprise applications no longer fit in a single data center. Routing traffic to the right region first, then distributing to a healthy service within that region, isn't two separate problems — it's two steps of the same decision.
A disaster recovery plan, multi-geography delivery, hybrid data center scenarios, or a multi-region user base — all demand a decision beyond the delivery layer: which region should the user's request go to? In the classical approach, DNS acts as a static record system; routing decisions are static or manual, while intra-region distribution is the job of a separate product.
TR7 Geo Bundle brings these two decisions into one package. GTM produces every DNS response based on health, latency, geography, and traffic policy; ADC publishes, distributes, and keeps the application alive within each region. The same backend-services pool, the same health check, the same operator UI — the multi-region architecture is managed in one product. The bundle also includes the two-region scope of the TR7 Central Management add-on; in disaster recovery scenarios both data centers are managed from one console.
Global Routing. Local Delivery. One Platform.
TR7 Geo Bundle brings together GTM, which makes the region decision at the DNS layer, and ADC, which carries the traffic within the region — on the same platform. Health data, service definitions, and the operator UI are shared.
2 Products + 1 Add-on, One Bundle
Geo Bundle delivers ADC and GTM at full capability — plus TR7 Central Management's two-region scope, included. Global routing, in-region delivery, and a single console for primary/standby data centers all run on one license, from one UI.

Explore TR7 Central ManagementGlobal Routing and Local Delivery, Fed by the Same Health Signal
In multi-region applications, one decision can't be independent of the other: which region to route to depends on the health of services in that region; the distribution decision within a region depends on the failover policy outside it. ADC and GTM make this decision as one decision.
One health signal feeds both layers
When a backend in one region becomes unhealthy, ADC already sees it and pulls it from local rotation. The same health information reaches GTM's DNS responses — the affected region is removed from the answer set. No two separate monitoring infrastructures, no two separate health endpoints, no two separate alert rules.
One backend-service definition, used globally and locally
A backend-services pool is defined once. ADC load-balances to that pool inside a region, while GTM uses the same pool as the source of its global-routing decision. When a region changes or a new data center is added, you don't update inventory in two separate products.
One decision, within a millisecond budget
After the DNS response is sent, ADC carries the traffic; because both layers are part of the same engine, there's no coordination lag. Region decision and service selection run on the same policy model.
One operational discipline
The DNS team and the ADC team operate from the same console. Policy changes are made through the same rule logic. Classic scenarios like "the DNS changed but the ADC didn't notice" or "ADC failed but GTM kept routing there" simply disappear.
Five Scenarios Where Geo Bundle Speaks Loudest
The ADC + GTM combination solves the problems multi-region enterprise applications face in the real world. In every scenario, local delivery and global routing operate on the same policy plane.
Disaster recovery — primary + standby data center
One application across two or more regions — primary + DR, Europe + US, Istanbul + Ankara. GTM routes traffic to the primary while it's healthy; on health failure, it automatically shifts to the standby. ADC carries the application in each region, GTM makes the region decision. No manual intervention required; bidirectional scenarios let you define separate policies for switch-over and switch-back.
Multi-region active-active delivery
An enterprise application running simultaneously in multiple geographies. European users go to the EU data center, Asian users to the APAC region, LATAM users to the local data center. ADC handles local distribution in each region while GTM picks the optimal region based on user location and latency signals.
Hybrid data center and cloud region
Some applications run in the on-prem data center, others in a cloud region. GTM unifies both environments under one DNS policy; ADC publishes locally in each. The hybrid architecture looks like a single multi-region setup from the operator's view.
Gradual rollout and A/B testing at the DNS layer
Start a new application version with 10% of traffic, confirm it's healthy, and gradually scale to 100%. Blue/green transitions, A/B distribution, and canary scenarios are managed via weighted DNS responses. ADC distributes within regions while GTM splits traffic across regions or service versions by ratio.
Geo-based enforcement and compliance routing
Data residency rules, regulator requirements, or sanction lists may require specific user groups to reach only specific regions. GTM applies geography-based response policies; ADC handles distribution once traffic reaches the region. Policy changes apply live, no architectural redesign required.
Not Two Products — Two Layers That Share the Same Health and Service Data
In TR7 Geo, ADC and GTM aren't separately managed products. They share the same definitions, see the same health signal, and operate from the same operator console.
Live health signal from ADC to GTM
When a backend in one region becomes unhealthy, GTM doesn't try to rediscover it; it shares the same health information. DNS responses remove the affected region from the answer set and users are routed to healthy regions — no separate per-region monitoring infrastructure needed.
One backend-services pool definition
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.
One certificate lifecycle
Certificates obtained via ACME or managed through an internal PKI bind to one store. When the same certificate is used across multiple regions, there's one renewal and distribution operation; no per-region renewal process.
Hot configuration reload — even during region transition
DNS policy or ADC distribution-rule changes apply to live traffic; active connections aren't affected during region transitions. No change-synchronization issue between two separate products.
One License. No Per-Region Meter. No Separate DNS Appliance.
Buying the local-delivery and global-routing layers of multi-region application infrastructure as a bundle delivers measurable operational and financial advantages over buying them separately.
One license, no per-region uplift
TR7 Geo Bundle ships ADC and GTM capabilities under one license. When you add a new region, there's no add-on license for the DNS module, no query-count meter, no region-tier upgrade. Your licensing model doesn't change as multi-region architecture grows.
No separate DNS appliance or management VM
GTM is part of the same platform as ADC; you don't deploy a separate DNS appliance, a separate central management server, or a separate analytics VM. Multi-region architecture starts without extra operational footprint.
Three decisions you don't make twice: service pool, health check, certificate
You don't define the same backend-service pool, the same health check, or the same certificate separately in two products. Defined once, used by both layers. The duplicate-definition burden in multi-region architecture disappears.
Stays on-prem — no cloud DNS provider lock-in
DNS responses, health signals, and traffic decisions are processed in your own infrastructure; they don't move to a third-party cloud DNS service. Critical for data sovereignty, regulator compliance, and operational independence.
Adaptive health and baseline learning per region
Adaptive L4/L7 DDoS protection learns each region's own traffic normal. Defense applies against each data center's actual behavior, not against a static global threshold. Even when traffic character varies across regions, deviations are caught accurately.

DetailsValidated by the Teams Running Multi-Region Architecture
Verified G2 reviews from infrastructure architects, network teams, platform leaders, and disaster-recovery owners.
"We defined separate policies for automatic switch-over from our primary data center to the standby region and for switch-back. We no longer need the scripts we used to write to synchronize our DNS provider and our ADC; in TR7, these two layers share the same health signal."
"We manage our three-region active-active delivery from one operator UI. Adding a new region didn't require a separate DNS license, a query-count meter, or a separate analytics VM."
"We run our geography-based routing policy for data-residency requirements at the DNS layer. ADC distributes the application within the region while GTM preserves compliance boundaries; one policy managed in one product."
