Here's our take.

Distributed Database

Nice Pick

Pick CockroachDB when you need Postgres-wire compatibility plus zero-touch multi-region survivability and can live with source-available licensing (no CockroachDB-as-a-service from a competitor)

Pros

• Pick TiDB instead if your app is already MySQL and you want HTAP without bolting on a separate warehouse
• Related to: postgresql, mysql

Cons

• Specific tradeoffs depend on your use case

Shared Disk Architecture

Developers should learn Shared Disk Architecture when building or maintaining systems that require high availability, load balancing, and data consistency across multiple servers, such as in database clustering (e

Pros

• Related to: storage-area-network, network-attached-storage

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Distributed Database is a database while Shared Disk Architecture is a concept. We picked Distributed Database based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Distributed Database wins

Based on overall popularity. Distributed Database is more widely used, but Shared Disk Architecture excels in its own space.
