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