Update: 2025-08-25
Description
Architecture Corner Newsletter PodcastWhen disaster strikes and takes down an entire region, can your application keep serving users without missing a beat? Multi-region active-active setups promise the shortest recovery times, but they come with their own set of challenges around data synchronization, routing, and complexity trade-offs.
In this episode we will cover:
- The three core patterns for active-active architectures: Read Local/Write Global, Read Local/Write Partitioned, and Read Local/Write Local
- How to handle the fundamental requirements of name resolution, application synchronization, and data replication
- Managing race conditions and data consistency across distributed regions
- Strategic approaches to selecting which parts of your system truly need active-active treatment
- Real-world implementation considerations using cloud services for routing, deployment, and data synchronization
- When the added complexity and cost of active-active makes sense for your organization
