Understanding high availability and disaster recovery for {{site.data.keyword.appid_short_notm}}

{: #ha-dr}

{{site.data.keyword.appid_short_notm}} is a highly available, regional service that runs in the following regions:

  • Dallas (us-south)
  • Frankfurt (eu-de)
  • London (eu-gb)
  • Osaka (jp-osa)
  • Sao Paulo (br-sao)
  • Sydney (au-syd)
  • Tokyo (jp-tok)
  • Toronto (ca-tor)
  • Washington (us-east)

In each supported region, the service exists in multiple availability zones with no single point of failure. However, because {{site.data.keyword.appid_short_notm}} is a regional service, there is no automatic cross-regional failover or cross-regional disaster recovery. If all the availability zones in a region fail, {{site.data.keyword.appid_short_notm}} becomes unavailable in that location. To establish cross-region high availability and implement a recovery plan, you need to create and maintain backup instances in multiple regions. To synchronize a service instance in one region with an instance in another region, you can use the APIs{: external}.
