Cloud computing 
Cloud computing is the delivery of services of the 
computing a service rather than a product, whereby 
shared resources, software, and information are 
provided to computers and other devices as a utility 
(like the electricity grid) over a network (typically the 
Internet). Clouds can be classified as public, private or 
hybrid.

Public Cloud 
• A public cloud is a cloud computing model in 
which services, such as applications and 
storage, are available for general use over the 
Internet. Public cloud services may be offered 
on a pay-per-usage mode or other purchasing 
models. An example of a public cloud is IBM’s 
Blue Cloud.
Public Cloud
Private Cloud 
• A private cloud is a virtualized data centre that 
operates within a firewall. Private clouds are 
highly virtualized, joined together by mass 
quantities of IT infrastructure into resource 
pools, and privately owned and managed.
Private Cloud
Hybrid Cloud 
• A hybrid cloud is a mix of public and private 
clouds.
Hybrid Cloud
Community Cloud 
• A community cloud is an infrastructure shared 
by several organizations which supports a 
specific community.
Service models 
• Infrastructure as a service (IaaS) 
• Platform as a service (PaaS) 
• Software as a service (SaaS)
Service models
Infrastructure as a service 
• To deploy their applications, cloud users install 
operating-system images and their application 
software on the cloud infrastructure. In this 
model, the cloud user patches and maintains 
the operating systems and the application 
software. Cloud providers typically bill IaaS 
services on a utility computing basis: cost 
reflects the amount of resources allocated and 
consumed.
Infrastructure as a service
Platform as a service (PaaS) 
• In the PaaS models, cloud providers deliver a computing 
platform, typically including operating system, 
programming language execution environment, database, 
and web server. Application developers can develop and 
run their software solutions on a cloud platform without 
the cost and complexity of buying and managing the 
underlying hardware and software layers. With some PaaS 
offers like Microsoft Azure and Google App Engine, the 
underlying computer and storage resources scale 
automatically to match application demand so that the 
cloud user does not have to allocate resources manually. 
The latter has also been proposed by an architecture 
aiming to facilitate real-time in cloud environments.
Platform as a service (PaaS)
Software as a service (SaaS) 
• In the business model using software as a 
service (SaaS), users are provided access to 
application software and databases. Cloud 
providers manage the infrastructure and 
platforms that run the applications. SaaS is 
sometimes referred to as "on-demand 
software" and is usually priced on a pay-per-use 
basis. SaaS providers generally price 
applications using a subscription fee.

BENEFITS OF CLOUD 
• Achieve economies of scale 
• Reduce spending on technology infrastructure. 
• Globalize your workforce on the cheap. 
• Streamline processes. 
• Reduce capital costs. 
• Improve accessibility 
• Monitor projects more effectively 
• Less personnel training is needed. 
• Minimize licensing new software 
• Improve flexibility.
Disadvantages of Cloud Computing 
• Possible downtime 
• Security issues. 
• Cost. 
• Inflexibility 
• Lack of support
