What is Cloud Computing?Cloud Computing architecture

provides on-demand access to shared pool of computer resources

Data and software packages are stored remotely in servers

Allows access to information and services using internet enabled hardware at the client’s end

Evolution of IoT with Cloud

1st Generation: Isolated applications with local internal memory storages

2nd Generation: Isolated applications connected to remote isolated database storages over the internet

Smart Generation: Interconnected applications with centralized cloud data storages = Internet of Things

How IoT Smart Devices Connect with Cloud

9

Application Programming Interface (API) is a gateway which provides direct interface between smart devices and users

Uses HTTP for data transfer between devices and storage centers

Popular Cloud APIs: Google Compute Engine, Amazon.com, Appistry

Protocols Used in IoT Cloud APIs

10

For device to Cloud Communication: Representation State Transfer (REST) & Simple Object Access Protocol (SOAP)

For secured delegated access to the right information by the right user: Open Authorization (OAuth)

The Future…
