• Cloud Computing Basics
• Advantages of Cloud
Computing
• Types of Cloud Computing
• Amazon Web Services
• Amazon EC2 -Demo
• AMI, instance, key pairs,
security group,
Availability Zone, Regions
etc.
Agility – where users has independence to re-provision a
technological infrastructure of the organization.
Cost – pay as you go service, no need to purchase any heavy
server and storage equipment.
Device and location independence – As cloud infrastructure
is offsite and an access via the internet, user can connect from
anywhere and any device.
Maintenance – As organization does not need to install any
physical device on their location, so there is no pain of
maintenance or IT support.
Multi-tenancy – Enables sharing of cloud resources (server, storage
& apps) among large number of users without worrying about load
capacity, efficiency and utilisations.
Performance - is good because of consistent and loosely
coupled architecture.
Security – is more than owing an infrastructure as cloud
providers always follows disaster recovery, latest operating
systems, high end data storage, backup services, networking
services, mirrored websites, internet based clusters.
Unlimited Computing Power and storage – Organization as ability
to increase the memory, processing power and another hardware
configuration at any point during their usage.
Based on cloud
location, we can
classify cloud as:
Public
Private
Hybrid
Community
IaaS (Infrastructure-as-a-Service) = Cloud
Infrastructure Service
e.g. :- AWS(Amazon web services), Windows
Azure, Google Compute Engine (GCE)
PaaS (Platform-as-a-Service) = Cloud Platform
Service e.g. :- Google App Engine, Engine Yard.
Google claims it has 200,000 developers building
applications on top of its App Engine PaaS.
SaaS (Software-as-a-Service) = Cloud Application
Service
e.g. :- Google Docs, Gmail, Cisco Webex,
Salesforce, Citrix GoToMeeting

• Amazon EC2 also known as Amazon Elastic Compute Cloud provides resizable computing capacity
in the Amazon Web Services (AWS) cloud. Allows users to rent virtual computers on Amazon Cloud.
2
• Using EC2, it eliminates the need to invest in computing hardware up front, which saves money but
also allows applications to develop and deploy faster.
3
• EC2 allows scalable deployment of applications by providing a web service, through which a user can
boot an AMI (Amazon machine image) to create a virtual machine, which Amazon calls an "instance“
4
• EC2 instance will automatically scale up to add capacity to handle the extra traffic. It supports Elastic
load balancing for better service.
5
• Amazon EC2 has Elastic Block Store (Amazon EBS) and Auto Scaling capabilities to make it easy for
better performance and availability for your applications.
Compute
Storage
EC2
Provides virtual, scalable private servers using Xen
S3
Simple Storage Service - It provides the storage based on the
web service calls.
It provides long term data storage option where
Glacier
organization has to access the data with low frequent
Database
Networking
access time.
VPC
RDS
Simple
DB
Dynamic
DB
Virtual Private Cloud – It creates logically virtual VPC instance
of EC2 for each VPN connection.
Relational Database Service – RDS provides database solution
with MySQL, Oracle, SQL Server, PostgreSQL etc.
Allows developers to run query on structure data. It operates
in EC2 and S3 environment.
It is no SQL online database service.
Private IP – Amazon provides Private IP when you launch an
instance. This can be used for communication between the
interfaces.
Public IP – Amazon also provides public IP to communicate
between instance and internet.
Elastic IP – To assign static IP address to your EC2 instance. If you
reboot the instance a new Public IP address is assigned. To
reserve the IP address, use Elastic IP.
Traditional Capacity Server - 2
2nd server instance for high
traffic 8 hrs.
Capacity of only 1 server
At the end of the day, 1/3rd
savings with EC2
1 server instance for 8 hrs.
1 server instance for 8 hrs.
1 server instance for 8 hrs.
