Serverless Databases: Pay for Use, Not for Idle
A serverless database automatically scales compute and storage based on demand, from zero to massive, without you managing any servers. Use it for spiky, unpredictable workloads to avoid paying for idle capacity.
CDN Edge Computing: Code at the Cache
CDN Edge Computing runs your code at the network edge, not just caches files. It's for low-latency tasks like A/B testing or auth checks. The footgun is treating it like a full backend; it's stateless and resource-constrained.
FaaS: Run Code, Not Servers
FaaS lets you run code without managing servers, like renting a contractor for one task. It's ideal for event-driven actions like processing uploads or handling webhooks. The footgun is cost: for high, steady traffic, a dedicated server is often cheaper.
Google BigQuery: A Serverless Data Warehouse
Think of BigQuery as a massive SQL database you don't have to manage. It's a serverless data warehouse for analyzing huge datasets, like terabytes of application logs. The footgun is treating it like a regular database for real-time transactions.
