Scalability is the measure of a system's ability to handle growing amounts of work by adding resources. When traffic spikes, a scalable application maintains its performance, speed, and reliability. Architects look at scalability through three main lenses:

Data is written to the cache immediately, and the cache asynchronously updates the database later. 6. Asynchronous Processing and Event-Driven Architecture

Every non-failing node returns a non-error response (without the guarantee that it contains the most recent write).

In a distributed network, partitions are inevitable. Engineers must choose between Availability (AP systems) or Consistency (CP systems) during a network failure. 2. Managing Data at Scale
