1 - What is Cloud Computing?

Region

A geographical area where cloud resources, such as data centers and networking infrastructures, are located.

Router

A networking device that forwards data packets between computer networks.

Switch

A networking device that takes a packet and sends it to the correct server/client on your network.

Compute Storage Data transfer OUT of the cloud

AWS has 3 pricing fundamentals that follow the pay-as-you-go pricing, which are:

Database

An organized collection of structured data stored electronically in a computer system.

Network

Cables, routers, and servers connected with each other.

Data centers

Centralized facilities used by organizations to house computing and networking equipment.

Private cloud

Cloud model in which cloud services are used by a single organization and not available to the public.

Hybrid cloud

Cloud model in which some servers are kept on premises and extends some capabilities to the cloud.

Public cloud

Cloud model where cloud services are provided over the public internet.

Infrastructure as a Service (IaaS)

Cloud service in which the infrastructure is managed for you - servers, network, virtualization, and data storage - through internet connection

Software as a Service (SaaS)

Cloud service that delivers software applications - which the cloud provider manages - to its users.

Platform as a Service (PaaS)

Cloud service that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure.

Edge locations

Endpoints that cache copies of data for faster delivery to users.

RAM

Memory that provides temporary storage space for data and instructions that the CPU needs to access quickly.
