Cloud Computing Fundamentals

This set of vocabulary flashcards covers the fundamental definitions, deployment types, and economic benefits of cloud computing as discussed in the lecture.

Cloud computing

The on-demand delivery of computing services over the internet where users rent access to resources from third-party providers and pay only for what they use.

Computing services (IT resources)

Resources that include servers, storage solutions, databases, networking components, and artificial intelligence and machine learning ($AI/ML$) tools.

Cloud-based deployment

A remote, online deployment type where users have the flexibility to migrate existing cloud designs and new applications within the cloud environment.

On-premises deployment

A physical, local deployment using virtualization and resource management tools to host software and data on a user's own physical servers and infrastructure.

Hybrid deployment

A mix of remote cloud-based resources and physical on-premises infrastructure working together, which is best for legacy applications that need to stay on premises.

Fixed expenses

Costs that stay the same each month regardless of usage, such as buying a delivery truck or maintaining private computer servers.

Variable expenses

Costs that change depending on how much a resource is used, allowing expenses to better align with actual usage for more financial flexibility.

Massive economies of scale

An economic benefit where the vast global infrastructure of AWS results in lower prices per unit, as hardware is purchased in bulk and savings are passed to customers.

Stop guessing capacity

A cloud benefit allowing customers to dynamically scale resources up or down based on real-time demand to achieve optimal performance without over-provisioning.

Increase speed and agility

The ability to rapidly deploy applications and services, accelerating time to market and facilitating quicker responses to changing business needs.

Stop spending money to run and maintain data centers

A cloud benefit that eliminates the need for businesses to invest in utilities and ongoing maintenance of physical servers, allowing resources to be reallocated to strategic initiatives.

Go global in minutes

The ability to use AWS's robust global infrastructure to deploy applications across multiple regions around the world quickly without building data centers in other countries.
