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).
In Depth
Scalability is essential for customer support platforms because support volume is inherently unpredictable — product launches, outages, seasonal peaks, and viral events can cause sudden spikes. Horizontal scalability (adding more servers) is preferred for modern cloud applications because it offers virtually unlimited growth potential. AI-powered support platforms must scale across multiple dimensions: conversation handling capacity, AI model inference throughput, knowledge base search performance, and integration API call volumes.
One of AI agents' greatest advantages over human support is near-infinite scalability — while hiring and training human agents takes months, AI agents can handle 10x or 100x more conversations simply by scaling cloud infrastructure, often automatically.

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.
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.
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.
