14.2.1 - Cloud Scalability and Elasticity

Vocabulary flashcards covering key concepts from cloud scalability and elasticity in computing.

Scalability

The ability of a system to handle increasing amounts of work or to be easily enlarged.

Elasticity

The ability of a system to handle changes in demand in real time without affecting performance or service.

Resource Pooling

A cloud computing principle where physical resources are pooled together to serve multiple customers, rather than being dedicated to a single user.

Virtualization

The creation of a virtual version of a resource, such as a server, storage device, or network, allowing for more efficient resource management.

Horizontal Scaling (Scaling Out)

Adding more nodes to a system to handle increased demand.

Vertical Scaling (Scaling Up)

Adding more resources to an existing node to increase capacity.

On-Demand Resources

Resources such as server instances or storage that are provided as needed by cloud services.

Cost Management in Cloud Computing

The ability to adjust resource allocation to reduce costs when demand is low, as part of elasticity.

Provider's View of Cloud Computing

Provisioning cloud services involves managing a large-scale datacenter to offer resources to clients.

Client's View of Cloud Computing

Clients are concerned only with the services provided by the cloud, without needing to understand the underlying infrastructure.
