Scalability Standards · PERF-02
Systems should utilise caching in order to provide more scalable data access · PERF-02.2 · SHOULD · DEV
Caching increases cost and complexity, therefore this must be a consideration rather than a mandate, and the costs and benefits should be communicated to the client where appropriate.
A distributed caching solution should generally be preferred in order to best enable horizontal scalability.
Asynchronous operations should be preferred where possible · PERF-02.3 · SHOULD · DEV
Where an operation does not need to be performed synchronously, technologies like message queues and events should be used in order to process actions asynchronously.
Common examples include:
- Sending an email
- Writing to an audit log
- Notifying an external system of an event
