Description: Multi-AZ, or Multi-Availability Zone, refers to the deployment of resources across multiple Availability Zones to ensure high availability and resilience in IT infrastructure. This approach is fundamental in cloud architectures, where resources are distributed across different geographic locations within the same region. Availability Zones are physically separated but interconnected data centers that allow organizations to mitigate the risk of single points of failure. By implementing Multi-AZ, applications can continue to operate even if one Availability Zone encounters issues, as traffic is automatically redirected to the remaining operational zones. This strategy not only enhances availability but also optimizes performance by balancing the load across different zones. Additionally, the use of Multi-AZ is a best practice for critical services and applications, where data loss or service disruption can significantly impact business operations. In summary, Multi-AZ is an essential technique for building robust and reliable cloud systems, ensuring that applications remain accessible and functional at all times.
