Question 1 of 5
What is the key distinction between a system being 'scalable' and a system being 'elastic'?
Scalability refers to adding more CPUs to a single server, whereas elasticity refers to adding more physical servers to a cluster.
Scalability is the architectural capacity to handle increased workloads by expanding the hardware footprint, while elasticity is the ability to automatically scale resources up or down in real-time based on immediate demand.
Scalability applies only to databases, while elasticity applies only to caching layers.
Scalability guarantees zero downtime, whereas elasticity always requires manual intervention to deploy code.
