Global Traffic Manager

Allows you to access the nearest node based on the Domain Name System (DNS) architecture. With built-in health checks, you can easily monitor your applications and run a failover when a failure occurs on a node.

Intelligent DNS Resolutions

Global Traffic Manager allows you to access the nearest node wherever application or website is located and balance concurrent workloads between multiple nodes based on the DNS architecture. With built-in health checks, you can easily monitor the health of your application and run DNS failover to meet any disaster recovery requirements.

Health Checks

Allows you to perform protocol-based health checks to retrieve the status of application services through the ICMP, TCP, and HTTP(S) protocols.

Failover

Supports the failover between DNS servers. You can isolate failed IP addresses and switch application services running in a failed data center to another data center.

Load Balance

Allows you to use round robin and weighted round robin to manage traffic.

Features

Address Management

Allows you to group application service addresses into multiple address pools to facilitate the management and simplify the configuration of global load balance.

Address Pool Management

Allows you to place multiple IP addresses of an application service into an address pool for easy management. For user access from specific regions, address pools provide you with flow control and load balance.

Custom Address Properties

You can specify different properties for the IP addresses of an address pool. For example, you can enable IP address A and disable IP address B.

Compatibility with Multiple Protocols for Health Check

Supports health checks through the ICMP, TCP, and HTTP(S) protocols to check the status of application services.

Health Checks

Allows you to monitor application services in real time through the ICMP, TCP, and HTTP(S) protocols and obtain the status of application services.

Distributed Health Check Nodes

Health check nodes are distributed across regions worldwide, which allows you to monitor application services anytime and anywhere.

Health Check Templates

You can also configure check templates and perform health checks by using multiple check templates together.

Flexible Access Control

Provides you with intelligent resolution services that allow access to the nearest address pools from end-users based on metrics, such as carriers and regions.

Geolocation-based smart DNS

Allows you to access an address pool that is situated nearest to your location.

Latency-based access policies

These policies allow GTM to detect the access latency between the location of a user and the region in which an application is deployed. Then, GTM routes user requests to the application server cluster that has the lowest latency. This feature is available only for the Ultimate Edition.

Automatic Failover

Allows you to perform failure isolation when balancing workloads between multiple IP addresses. This ensures the failover between primary and secondary instances and meets the zone-disaster recovery and geo-disaster recovery requirements.

Active Zone-redundancies

Allows you to isolate one or more failed IP addresses from the other IP addresses in an address pool based on the health check results of each IP address.

Geo-disaster Recovery

Allows you to migrate IP addresses from unavailable address pools to redundant address pools based on the predefined failover policies.

Typical Scenarios

Combine Multiple Load Balancing Policies to Easily Adapt to Various Scheduling Scenarios

Multiple load balancing policies are supported, including Poll, Weight, Order, and Closest to Source. You can use a single policy or combine multiple policies to create a traffic distribution solution based on your business requirements.

Benefits

  • Scheduling based on multiple policies

    You can use multiple load balancing policies together to implement flexible traffic scheduling.

  • Meeting more scheduling requirements

    You can use the complex combinations of load balancing policies to easily meet various traffic scheduling requirements.

Combine ISP Lines and Regional Lines to Implement Finer-grained Source Identification

You can combine multiple types of request lines, such as ISP lines, regional lines, and Alibaba Cloud lines, to implement fine-grained traffic management by adjusting traffic distribution based on request sources.

Benefits

  • Inability to use multiple types of lines together

    You can combine multiple types of request lines, such as ISP lines, regional lines, and Alibaba Cloud lines. This helps implement fine-grained traffic management for different request sources.

  • Line double matching

    Double matching is supported for lines. For example, you can match lines based on the region and then based on the ISP to implement accurate traffic scheduling.

  • Decoupling the line configuration from the domain name plan

    The line configuration is decoupled from the domain name plan, which improves the independence and flexibility of line configuration.

Global Business Switching upon Emergencies

In failure scenarios, such as a single application failure, a specific data center failure, and a specific egress link failure, an appropriate traffic switching solution is important. GTM must adjust the traffic switching solution in a flexible manner based on the failures. This ensures that traffic can be efficiently and intelligently routed to available applications, data centers, or egress links based on actual conditions.

Benefits

  • Batch traffic switching and overall recovery

    You can use multi-attribute annotations, filter applications, and enable or disable traffic in a centralized manner.

  • Multi-level management and on-demand traffic switching

    You can enable or disable domain names, address pools, and addresses at each level and switch traffic in a flexible manner.

Interaction with GTM to Route Traffic to Acceleration Areas

Suitable for enterprises with cross-region and cross-border business, such as international enterprises expanding business in China and Chinese enterprises with overseas business.

Benefits

  • User Access Acceleration

    To accelerate Internet access, Alibaba Cloud DNS and Global Traffic Manager (GTM) can work together to route traffic to acceleration areas that are deployed with Global Accelerator (GA) and nearest to users.

  • Health Check and Failover

    GTM provides health check and failover capabilities for the acceleration areas of GA and origin servers. This improves the security and stability of enterprise websites.

  • Fast Disaster Recovery Design

    Interaction between Alibaba Cloud DNS and GTM is cost-effective and easy and needs a short preparation period. Enterprises can efficiently build the disaster recovery architecture without the need to change the existing website architecture.
