Cosmos DB Disaster Recovery: Multi-Region Write Pitfalls and How to Evade Them

Introduction: Challenges of Multi-Region Writes in Azure Cosmos DB

Azure Cosmos DB stands out as a premier global distributed, multi-model database service, offering high availability, low-latency access, and seamless scalability. Its feature of multi-region writes, allowing applications to write to the closest regional replica, enhances performance and resilience significantly.

However, despite its advantages, enabling multi-region writes in Azure Cosmos DB presents new hurdles, particularly in disaster recovery (DR) scenarios. Without meticulous planning, organizations may face issues such as data conflicts, unexpected downtime, or even loss of critical data.
