Oracle Cloud Infrastructure (OCI) Traffic management—a critical component of DNS—enables users to configure routing policies to serve intelligent responses to DNS queries. Oracle Traffic Management steering policies are used to steer DNS traffic across multiple public Oracle Cloud Infrastructure instances and other private and third-party assets.
Public DNS steering policies are not limited to assets in Oracle Cloud Infrastructure, making Oracle DNS the best choice for hybrid and multicloud architectures. Traffic management steering policy types include:
Global server load balancing enables you to use round robin load balancing to distribute traffic among multiple servers to optimize performance. Traffic can be split evenly among endpoints or weighted via ratio assignment.
It’s easy to set up a simple active-active failover between two public assets. Oracle Cloud Infrastructure will monitor the primary endpoint (via Oracle Health Checks) and reroute all traffic to a failover location if the primary endpoint is unresponsive.
Traffic steering policies can also route traffic based on the source of the query. Geolocation steering dynamically routes requests to the appropriate response pool based on the physical location of the originating request.
Dynamically routes traffic requests based on the originating ASN or IP prefix.
Dynamically routes traffic requests based on originating IP prefix (for example, 172.16.1.0/24).
Easy to configure Oracle Cloud Infrastructure Health Checks for external monitoring from vantage points around the globe.
Securely connect to workloads in other providers’ cloud services.
No contracts or commitment. Build as many IPSec tunnels to Oracle Cloud Infrastructure as you want and keep them active as long as you want.
Cloud DNS load balancing—ratio load balancing, in particular—is perfect for controlling your migration to the cloud. Simply steer a small percentage of traffic to the “new” infrastructure, monitor the results, and increase the amount of traffic at your own pace.
Distribute load across multiple compute instances as you scale mission-critical applications and leverage Oracle Health Checks to ensure users are sent to healthy endpoint.
Traffic steering policies work with any public-facing endpoint and serve as a control plane for any combination of your own data centers and cloud infrastructure instances.
With Oracle Cloud Infrastructure's industry-leading geolocation data, you can ensure the lowest-latency response for end users. This same data can also help with compliance based on the users’ countries of origin.
Control access to new or beta features before rolling out for general availability with source-based steering policies based on geolocation or IP prefix.
In this case, conditional steering is based on the originating enterprise, mobile operator, or other communications provider. Preferred autonomous system numbers (ASNs) can be directed to free resources while all other traffic can be directed to paid resources to support commercial agreements that may be in place.
