Load-balancing through DNS SRV¶
You can distribute load across several nodes using DNS SRV lookup.
Originating customers should be configured to use DNS SRV for each outgoing call.
Requirements:¶
- node count: 2+
- setup SRV records in your DNS zone to spread load
- setup your domain name in connection form for your customers
- notify customers about using DNS SRV for each call
- IP address count in data center = node count
Limitations¶
- not every equipment supports DNS SRV lookup.
Therefore, you won't spread load for those of customers, which doesn't support this feature.
