Elasticity
Elasticity is the ability of a cloud system to automatically scale resources up during demand spikes and scale down during quiet periods, optimizing costs.
In Depth
While scalability is the ability to grow, elasticity is the ability to grow and shrink dynamically based on actual demand. This distinction is important for cost management — you don't want to pay for peak capacity during off-peak hours. Elastic systems use auto-scaling policies that monitor metrics like CPU usage, queue depth, response latency, and concurrent connections to automatically add or remove resources.
For AI-powered customer support, elasticity means the platform handles Monday morning rush with full capacity and scales down on quiet Sunday nights, with costs tracking usage rather than peak provisioning. This elastic model makes AI agents extremely cost-effective compared to human agents, where staffing decisions must be made weeks in advance and you pay for agents whether they're handling conversations or waiting.

Scalability
Scalability is the ability of a system to handle increased workload by adding resources, either by upgrading existing hardware (vertical) or adding more machines (horizontal).
Cloud Computing
Cloud computing is the delivery of computing services — servers, storage, databases, networking, software, and AI — over the internet, offering scalable resources on demand.
Load Balancing
Load balancing is the process of distributing network traffic and workload across multiple servers to ensure no single server is overwhelmed, improving performance and reliability.
