Strong consistency and eventual consistency

 describe how data is kept synchronized across distributed systems. In strong consistency, once a write is confirmed, all clients immediately see the latest value on every read, regardless of which replica or region they access. It behaves like a single system, making reasoning about correctness easier, but often comes with higher latency and lower availability in globally distributed setups.

Eventual consistency, on the other hand, 

guarantees that if no new updates are made, all replicas will eventually converge to the same value, but in the short term, different clients may see stale or inconsistent data. This approach improves availability and performance by allowing replicas to serve reads before fully synchronizing. It is often used in large-scale systems like DNS, social media feeds, or shopping carts, where temporary inconsistency is acceptable.

👉 In short: Strong = immediate accuracy. Eventual = faster, but may show stale data temporarily.

Would you like me to also give real-world examples from databases (e.g., Spanner vs DynamoDB) for extra clarity?
