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