Chapter 8: Cloud Computing

Cloud computing is a type of computing that delivers on-demand, convenient, pay-as-you-go access to shared IT resources over the internet.
Four types of cloud computing: public, private, hybrid, and vertical.
Types of services on the cloud: Infrastructure as a service (IaaS), Platform as a service (PaaS), and Software as a service (SaaS).
Examples of cloud services: Salesforce, Gmail, Dropbox.
Cloud characteristics: on-demand, convenience, scalability (depending on need/season).

Wireless Technologies

Wireless technologies include mobile computing, mobile commerce, the Internet of Things (IoT).
Mobile computing involves changing locations. Some wireless networks are fixed (e.g., microwave towers), while others are mobile (e.g., MiFi).
Mobile commerce involves e-commerce transactions conducted on mobile devices.

The Internet of Things (IoT)

IoT means virtually every object has processing power with global network connectivity.
Examples: smart fridge, smart doorbell, smart lights, smart watch.
Three major advantages: small size, sufficient computing power, and wireless communication.
One disadvantage: worker data transmission risks for sensitive business information.

Wireless Transmission Media

Wireless media transmit signals without wires.
Major types of wireless media channels: microwave towers, satellite towers, and radio towers.
Electromagnetic waves are used for signal propagation.

Social computing combines information technology with social behavior to create value.
Techniques: weblogs, blogs, wikis
Examples: people commenting on products or expressing opinions.
Social networking sites allow users to upload content (text, voice, etc.)
