Cross-DC Extended Settings
The Cross-Data Center (DC) support provides protection against data center failure by setting up API Gateway across different data centers. It is important to have this support primarily for the following reasons:
*Disaster Recovery. When the primary data center goes down due to natural disaster, equipment failure, or cyber attack, a business has to recover lost data from a secondary data center where the data is backed up. The disaster recovery relies upon the replication of data and computer processing of the secondary data center in an off-premises location that is not affected by the disaster. Ideally, an organization transfers its computer processing to that secondary data center in order to continue operations.
The two most important parameters for a disaster recovery plan are:
*Recovery Point Objective (RPO). Describes the age of files that must be recovered from backup for business operation to resume after a disaster. It also specifies how often you should back up data.
*Recovery Time Objective (RTO). Describes the duration and service level within which you must restore the most critical IT services after a disaster.
*Load Distribution. Huge voluminous data can be managed by distributing the data across multiple data centers. Load distribution across data centers provides high performance data access for globally distributed, mission critical applications.
Deploying Cross-DC Support in API Gateway
The Cross-DC support is deployed in API Gateway in the following modes:
*Cold Standby
*Warm Standby
*Hot Standby
*Active - Active
Before you start setting up the data centers for a Cross-DC support, ensure that you have:
*Manage general administration configurations functional privilege.
*API Gateway installed in all the data centers.
