 Cloud

Infrastructure as a Service (IaaS).
 Cloud Platform as a Service (PaaS).
 Cloud Software as a Service (SaaS).

What is Cloud Infrastructure as a
Service (IaaS)?
- The capability provided to the consumer
- Fundamental computing resources
- Does consumer control or manage infrastructure?

Examples on infrastructure as a
services (AWS)


Elastic Compute Cloud (EC2)



Simple Storage Service (S3)

Deployment Models:
Private cloud :The cloud infrastructure is operated for an organization.

Community cloud :-

The cloud infrastructure is shared by several organizations that has
shared concerns (e.g, security requirements and policy).

Public cloud :-

The cloud infrastructure is available to the public and is owned by
on organization selling cloud service

Hybrid cloud:-

The cloud infrastructure is a composition of two or more clouds
(private, community, or public)
(e.g., cloud bursting for load balancing between clouds)

DataCenter
 Definition

of Data Center

The National Climatic Data Center
(NCDC),
for example, is a public data center 
NOAA's National Climatic Data Center
(NCDC) is responsible for
preserving, monitoring, assessing, and
providing public access to the Nation's
treasure of climate and historical weather
data and information

Inside Facebook's green and clean
arctic data center
 Facebook

built new Lulea green data
centre in Sweden
 It designed to take advantage of the subarctic location.
 A cold climate provides natural cooling for
the literally tens of thousands of servers Facebook won't say exactly how many
there are - packed together in long aisles.
This saves a lot of electricity

Chill wind: By locating the data center
in the far north of Sweden, Facebook
uses far less electricity to cool servers

this played an instrumental role in the
company's decision to move towards
using renewable energy in its data
centers.

 Advatages & Disadvantages of
IAAS



Presented by :-

 Amira Ahmed

Advantages of IAAS
 reduce


time & money

Utility Service :- IAAS follow A pay per
use

 Dynamic
 Flexible

Elasticity:- expand your storage

access:-can access IAAS on any
device and from any location

Disadvantages of (IAAS)
 Security

:- other say if you really
concerned ,you will keep it in house

 Compliance:-

in case of
Disaster recovery

 Outages:-

network crashes , service
outage by 99.9%

Different reactions about
infrastructure
(confidentiality ,integrity of data and
reluctance)
 Users

reaction:-

 enterprises
