Hopewiser operate servers on multiple independent sites to maximise the resilience of the service we provide.
We also operate a cloud load-balanced endpoint which uses IP anycast to provide a high level of protection with a minimum of customer configuration.
To ensure you qualify for protection under our SLA you must call the host:
- cloud.hopewiser.com
Alternatively, you can also qualify by providing your own failover mechanism (be it in your calling code or a software or hardware proxy or load balancer) to one of the acceptable combinations of hosts from the list below:
- cloud.hopewiser.com + soap3.hopewiser.com + soap4.hopewiser.com
- soap3.hopewiser.com + soap4.hopewiser.com
No other combinations qualify. If you choose to perform your own failover it is your responsibility to keep current with the list and ensure the correct functioning of your failover mechanism.
If you employ load-balancers you should use sticky sessions and strongly prefer using soap3 to soap4 as the latter has higher latency.
The client-side code for the Atlas drop-in will failover automatically and perform recovery actions as necessary when given multiple URLs separated by commas.
