The Oracle Cloud Infrastructure Traffic Management Steering Policies service is a critical component of DNS. Traffic Management Steering Policies enables you to configure policies to serve intelligent responses to DNS queries, meaning different answers (endpoints) may be served for the query depending on the logic the customer defines in the policy. Traffic Management Steering Policies can account for health of answers to provide failover capabilities, provide the ability to load balance traffic across multiple resources, and account for the location where the query was initiated to provide a simple, flexible and powerful mechanism to efficiently steer DNS traffic.
Traffic Management Steering Policies Service Components
The following list describes the components used to build a traffic management steering policy.
- steering policies
- A framework to define the traffic management behavior for your zones. Steering policies contain rules that help to intelligently serve DNS answers.
- Allows you to link a steering policy to your zones. An attachment of a steering policy to a zone occludes all records at its domain that are of a covered record type, constructing DNS responses from its steering policy rather than from those domain's records. A domain can have at most one attachment covering any given record type.
- The guidelines steering policies use to filter answers based on the properties of a DNS request, such as the requests geo-location or the health of your endpoints.
- Answers contain the DNS record data and metadata to be processed in a steering policy.
Ways to Access the Traffic Management Steering Policies Service
You can access Oracle Cloud Infrastructure using the Console (a browser-based interface) or the REST API. Instructions for the Console and API are included in topics throughout this guide.
To access the Console, you must use a supported browser. You can use the Console link at the top of this page to go to the sign-in page. Enter your tenancy, user name, and your password.
Authentication and Authorization
Each service in Oracle Cloud Infrastructure integrates with IAM for authentication and authorization, for all interfaces (the Console, SDK or CLI, and REST API).
An administrator in your organization needs to set up groups , compartments , and policies that control which users can access which services, which resources, and the type of access. For example, the policies control who can create new users, create and manage the cloud network, launch instances, create buckets, download objects, etc. For more information, see Getting Started with Policies. For specific details about writing policies for each of the different services, see Policy Reference.
If you’re a regular user (not an administrator) who needs to use the Oracle Cloud Infrastructure resources that your company owns, contact your administrator to set up a user ID for you. The administrator can confirm which compartment or compartments you should be using.
Traffic Management Steering Policies Service Capabilities and Limits
The Oracle Cloud Infrastructure Traffic Management Steering Policies service is limited to 100 policies and 1,000 attachments per tenant. See Service Limits for a list of applicable limits and instructions for requesting a limit increase.
Required IAM Service Policy
To use Oracle Cloud Infrastructure, you must be given the required type of access in a policy written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment you should work in.
If you're new to policies, see Getting Started with Policies and Common Policies. For more details about policies for Traffic Management Steering Policies, see Details for the Traffic Management Steering Policies Service.
