Question

An aviation tracking system maintains flight records for equipment and personnel. The system is a critical command and control system that must maintain a global availability rate of 99%. The entire system is on a cloud platform that guarantees a failover to multiple zones within a region. In addition to the multi-zonal cloud failover, what other solution would provide the best option to restoring data and rebuilding systems if the primary cloud service becomes unavailable?

Answer 1

To complement a multi-zonal cloud failover, a multi-cloud or hybrid cloud architecture along with regular data backups and disaster recovery planning can enhance the resilience of an aviation tracking system against cloud service outages.

Step-by-step explanation:

To ensure global availability and a 99% uptime for an aviation tracking system, it is essential to have robust disaster recovery strategies in place. A multi-zonal cloud failover strategy is a good start, but for additional protection against a primary cloud service outage, establishing a multi-cloud architecture or using hybrid cloud solutions can be highly effective. These approaches facilitate data and system replication across different cloud services, ensuring that even if one provider experiences an issue, the system can continue functioning seamlessly by switching to another provider.

Another beneficial solution would be to establish frequent data backups at various geographical locations and implement regular testing of the recovery process. This ensures that vital data can be restored and systems can be rebuilt quickly and efficiently in case of a disaster. The use of advanced disaster recovery planning and management tools can streamline these processes, providing continuous data protection and failover capabilities to another cloud platform or to a physical backup site if necessary.

Answer 2

To support a global aviation tracking system's need for 99% availability beyond multi-zonal cloud failover, implementing a multi-cloud strategy with offsite backup and a well-documented disaster recovery plan is critical. This includes real-time data replication and geo-redundant backups to ensure continuous operation and data integrity during unexpected outages.

Step-by-step explanation:

When maintaining high availability rates for critical systems like an aviation tracking system, it is essential to have a robust backup and disaster recovery strategy in place. In addition to utilizing a multi-zonal cloud failover approach, an effective solution should include offsite backup and disaster recovery planning.

One of the best options to consider is the implementation of a multi-cloud strategy, where backups and critical datasets are replicated to a different cloud service provider. This approach ensures that in the event the primary cloud provider becomes unavailable, the system can still function using the secondary provider. Another key component is implementing a geo-redundant backup, where data is stored in physically separate locations, further mitigating the risk of a single catastrophic event impacting all data stores.
