# Resources

The Akamai Global Traffic Management (GTM) has an optional feature called load feedback.  With load feedback, load balancing is controlled by measurements of entities, which you define, called *resources*.  GTM names are grouped by *domain* (for example, `example.akadns.net`).  Within a domain, you may have any number of *properties*, or fully qualified names (e.g., `images.example.akadns.net`).  Network traffic is balanced between *data centers*, also known as *regions* or *traffic targets*.

A resource is anything that is consumed by load on a data center, and is measured and reported to improve load balancing. As an example, for a database application, you might decide that the most important measurement of load is queries per second. For a static web server, you might choose to measure HTTP GET requests per second. A resource is simply a name for something you measure that reflects how you want to balance load across your datacenters. You report the load in whatever units make sense to you; to GTM, loads are just relative unit-less quantities. A resource may constrain a single property, or all properties in a domain.

An *instance* of a resource represents the current, target, and maximum load configured for a particular data center.

For a full description of GTM, our DNS-based load balancing, and all the terms used here, please see [Global Traffic Management](https://techdocs.akamai.com/gtm) and [Global Traffic Management API](https://techdocs.akamai.com/gtm/reference).
