Continuous Delivery high availability and disaster recovery

IBM Cloud® Continuous Delivery is a general availability (GA) service with a Service Level Agreement of 99.99% availability that is offered in multiple regions: Dallas, Washington, Toronto, Sao Paulo, Frankfurt, Tokyo, Sydney, Osaka, London, and Madrid. Each location has three different data centers for redundancy. The data for each location is kept in the three data centers near that location. If all of the data centers in a location fail, the Continuous Delivery service for that location becomes unavailable.

Continuous Delivery does not replicate data outside of a region, except for backup data. When possible, backup data is kept within the data centers of a country but data is always kept within a geography. European data does not leave the EU. To learn more about where Continuous Delivery backup data is stored, see Object Storage Location.

Continuous Delivery is available only on the public cloud, but the tools that are used with Continuous Delivery can run in public cloud environments and in on-premises environments.
