Distributed SQL represents an evolution in database technology, offering a scalable, resilient, and globally distributed solution that meets the demands of cloud environments while maintaining the reliability of traditional relational databases. As organizations move to the cloud, they find legacy databases lacking in scalability and global distribution, prompting a shift to distributed SQL solutions like Google Cloud Spanner, Amazon Aurora, Yugabyte, FaunaDB, and CockroachDB. These databases provide key features such as seamless scaling, transactional consistency, geo-replication, SQL language support, and the ability to operate across multiple cloud environments, addressing challenges like data locality and multi-cloud deployment. Foundational requirements for these databases include administration, optimization, security, and integration, ensuring they meet enterprise needs and can handle both mundane and mission-critical workloads. As the category matures, the focus is on implementing these advanced features effectively in production, marking distributed SQL as a significant advancement in managing data in the cloud.
