An SRV record is a DNS record, which is used to point a domain name to a third-party server and employ it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is set up, you could specify an Internet Protocol that the domain name will use and the port, which is to be employed to connect to the remote server. Moreover, in case you have numerous SRV records for the exact same service, you can set different priorities and weights for every single one of them, so you can spread the load between a number of machines. Such a record allows you to use the same domain name or subdomains under it with different providers, so you're able to employ it for various purposes even if you are not able to get all the services from one service provider.
