The successful migration to the Windows Azure SQL database primarily addresses availability problems by reducing the disruption of operations. In cloud environments like Azure, services are often designed with high redundancy, scalability, and automatic failover features. This means that in the event of an outage, the system can quickly switch to backup resources without significant impact to ongoing operations.

By leveraging a cloud-based solution, organizations can benefit from the cloud provider's infrastructures, such as load balancing and automated backups, which play a critical role in maintaining consistent availability. This reduces downtime and the operational disruptions that can occur when relying solely on on-premises databases or smaller-scale systems, which may not have the same level of resilience and flexibility.

On the other hand, while invasion of privacy, leak of sensitive information, and unauthorized access to data are important security concerns, they are not directly related to the primary goal of solving availability problems. These issues pertain more to data protection and security management rather than the operational capability and resilience provided by a robust cloud environment.
