Key Terms

Scalability
The capability of a system to increase its capacity and performance by adding resources.

Example: A web application that can handle more users by adding more servers.

Horizontal Scaling
Adding more machines or nodes to a system to handle increased load.

Example: Adding more servers to a web farm.

Vertical Scaling
Increasing the capacity of existing machines by adding resources like CPU or RAM.

Example: Upgrading a server's RAM to improve performance.

Load Balancing
Distributing workloads across multiple computing resources to optimize resource use.

Example: Using a load balancer to distribute traffic among several servers.

Fault Tolerance
The ability of a system to continue operating properly in the event of a failure.

Example: A system that can reroute traffic if one server goes down.

Distributed System
A system that consists of multiple independent components that communicate and coordinate with each other.

Example: A cloud storage service that uses multiple servers.
