WHAT IS CLOUD COMPUTING?

Internet –based computing

Shared resources

On demand with minimal management

There are many Service Models in cloud computing:

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 cleanarctic data center

Facebook built new Lulea green data centre in Sweden

It designed to take advantage of the sub-arctic 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 IAASreduce time & money

 Utility Service :- IAAS follow A pay per use

Dynamic Elasticity:- expand your storage

Flexible 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 and government
