Cloud computing allows for storing and accessing data and programs over the Internet instead of a local computer's hard drive. It provides scalable options including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Popular cloud platforms like Microsoft Azure and Amazon Web Services offer IaaS that provides access to servers, while PaaS handles provisioning machines for applications and provides databases and servers. SaaS delivers software through the cloud like Microsoft Office 365 and Google Apps. Open source projects such as Hadoop, OpenStack, and memcached help companies build cloud solutions that scale to thousands of nodes.

2. • The newest Technology Notion is without doubt the cloud :
While we are talking about the cloud, we thing about the big
data that requires new frameworks to make it easy to install
and maintain large number of cluster nodes, and easily
distribute software workload on these systems.
What is Cloud?

3. About the Cloud:
• There are many Valuable Projects such as the Famous
Microsoft Azure or Amazon … Again the open source projects
such as Apache Hadoop and memcached have been helping
Companies deliver solutions that are production ready and
scale well to thousands of nodes.

4. About The Cloud:
• Another Valuable open source project is OpenStack , which
helps set up , install and administer a cloud infrastructure.
Finally, We must know the open Source World and especially
the newest one that has a relation with the Cloud
Computing.

5. Three Types

6. Infrastructure as a service(IAAS)
• a provider that gives you access to all or part of its technical
infrastructure , in other words its servers.

7. Platform as a service (Paas)
• is not only provides access to the infrastructure , but also
responsible for managing the number of machines
needed for your application works well regardless of the
traffic load . It also gives you access to features such as
databases , servers cache of e-mail servers.

8. Sotware as a service(Saas)
• provides access to software as a service . Before , you
need to install the software on your machine (eg
Microsoft Office). Today , you just need to go to an
address and you can use it for example Microsoft Office
360, Google Apps ...
