This document provides an overview of cloud computing and the Internet of Things (IoT). It defines cloud computing as the on-demand delivery of computing resources over the Internet. It describes the common cloud service models of SaaS, PaaS, and IaaS. It also discusses characteristics of cloud computing like resource pooling, elasticity, and measured service. The document then introduces IoT and describes components of an IoT system including sensors, gateways, communication protocols, cloud platforms, and applications. It provides examples of services from major cloud platforms and discusses tools for visualizing IoT data.

3. Cloud Computing
➢ Cloud computing is the on-demand delivery of compute power,
database storage, applications, and other IT resources through a
services platform via the internet with pay-as-you-go pricing.
➢ It is the delivery of computing as a service rather than product
where shared resources, software and information are provided to
users as an utility.
➢ Moving from traditional to on-Demand model.
➢ The analogy is , 'If you need milk , would you buy a cow ?’.

5. Cloud Computing Service Models
• SaaS (Software as a Service)
- Access the services from provider. consumer uses an application, but does
not control the operating system, hardware or network infrastructure on which
it's running
• PaaS (Platform as a Service)
- The consumer uses a hosting environment for their applications. The
consumer controls the applications that run in the environment but does not
control the operating system, hardware or network infrastructure on which they
are running. Provides the middleware framework
• IaaS (Infrastructure as a Service)
- The consumer uses fundamental computing resources such as
processing power, storage, networking components

8. Security and Identity Services
8
Authentication :
- Allow Apps to authenticate on behalf of users
- Allow users
Authorization:
- Fine-grained access control
- Attribute management
- Policy evaluation
- Policy Management
Implementation:
OpenID- Created for federated authentication. User obtain account with OpenID Provider and
use the account into sign in with any other web services. Allows communication between IDP
and SP.
OAuth (Open Authorization) is for token-based authentication and authorization. Allows
users/application to access resources.
SAML: Security Assertion Markup Language. Open standard for authentication and
authorization.
SSO( Single Sign On) for Federation and Identity Management. One user name and password
to access multiple services.

12. Machine Learning
12
➢ Machine learning is a method of data analysis
➢ Using algorithms it iteratively learn from data and allows to find insights into this
data
➢ It allows learning from previous computations to produce reliable, repeatable
decisions and results
➢ Machine Learning enables computer system to mimic the working of the human
brain
✓ Data Collection: Collect the historical Data
✓ Data Preparation: Choose and classify the data
✓ Model Training: Selecting the algorithm for model
validation and Training
✓ Model Evaluation: Feed the data and test the accuracy
✓ Performance tune and improvement: Choosing different
model
Data collection and preparation is the key in Machine
Learning

13. Machine Learning –Models
13
• Training Data with Labels
• Classification ,Regression etc..
• Classifier based on input and
output data
• Used when "I know how to
classify this data, I just need
you(the classifier) to sort it."
Supervised Learning
Machine Learning
Un supervised Learning Reinforcement Learning
• Training Data without Labels
• Clustering ,Dimension
reduction etc..
• Algorithm based on input data
• Used when "I have no idea how
to classify this data, can
you(the algorithm) create a
classifier for me?"
• Iterative Rewards and
punishments
• Correct input and output pairs
are not presented a-priori.
• allows machines and software
agents to automatically
determine the ideal behavior
within a specific context.

19. What is IOT
➢ Internet is no longer just a global network for people to communicate
with one another using computers, but it is also a platform for devices
to communicate electronically with the world around them.
➢ Sensors/Things connected to server via network and deliver
connected industry solutions for efficient control and improved human
experience.
➢ Billions of connected devices is an indicator of IoT. The connectivity is
just an enabler but the real value of IoT is on data (business
insight/data-driven economy).

around and people realized that they can obtain native-
like functionality in the browser.
Native Applications:
• Native apps are written in languages that the platform
accepts
