Geo-Redundancy as a Disaster Recovery solution is defined as having multiple deployments of the same product across multiple geographic locations for low production downtime. When an entire site fails, the other site can be used in production to minimize the impact to the business. An individual site can also be referred to as a data center in this context.
A site is a geographical location where you deploy POM. A site contains all components on which POM depends. To leverage the benefits of Geo-Redundancy, you must deploy a POM system on more than one site.
For Geo-Redundancy, you must deploy the following sites:
When a site has a complete failure, for example, because of a power outage, network outage, or natural disaster, the standby site can be used for production. Geo-Redundancy enables continued operation with minimized impact if an outage occurs. In case of POM, this is achieved through a manual failover process and requires administrator intervention to switch operations from the active site to the standby site and vice versa. For Geo-Redundancy, the components or products on which POM depends must be administered identically in all the sites.
