## Entries

- [CAP Theorem](https://banes-lab.com/records/architecture/cap-theorem.md): A conceptual representation of the choice a distributed store makes during a network partition, between consistency and availability.
- [PACELC Theorem](https://banes-lab.com/records/architecture/pacelc-theorem.md): A conceptual representation that extends the CAP theorem with the trade-off a healthy network still forces, between latency and consistency.
- [Consensus](https://banes-lab.com/records/architecture/consensus.md): A mechanism that lets a quorum of nodes commit one value, so every correct node ends up with the same value.
