What takes down your biggest sale of the year isn't total load, it's the hot key: one hot partition that throttles while the rest of the table sits idle. Space-based architecture fixes that by taking the database out of the critical path. On AWS serverless you inherit the principle, not the literal implementation, and most projects don't even need it.

The biggest mistake in serverless architecture isn't technical, it's organizational. Without Domain-Driven Design, you sell team autonomy and deliver the opposite: a distributed monolith dressed up as microservices.

Discover how AWS Lambda Durable Functions lets you create workflows that pause, wait for human approvals, and resume after hours - without paying for wait time.
