- DNS Load Balancer
How to create a pool
- A pool is a collection of IP endpoints, usually with something in common like they are all in a specific geography, or they are all intended as backup.
- DNS Load Balancer directs traffic to pools based on proximity rules (where the request comes from), and then chooses an IP endpoint from the pool based on the selected load balancing method.
- If there is a problem with one of the IP endpoints as determined by its monitor, then that endpoint will be taken offline, and the load balancer will use one of the other endpoints.
- Name this pool - Specify a unique name for this pool. You will use this name when selecting pools creating your load balanced record
- What's the resource type? - Specify the DNS resource record type for the IP endpoints in this pool
- Choose a load balancing method - This choice will specify how DNS Load balancer will choose an IP address from the pool. for more information on load balancing methods, see Q&A: What are the different load-balancing methods and how do they work?
- Define TTL (Time to live) - This value is sent as part of the DNS response informing DNS clients how long an answer can be cached locally.
- Add notes here - Add any description or other information about the pool.

- Specify the maximum IP endpoints returned per response -
- Save and create another - If checked, then the Create button will create the pool you've specified, clear the fields, and allow you to immediately create another pool.
