WHAT IS CLOUD SERVICE?
1 st
• Use of hardware and software
resources as a service over a Internet
2 nd
• Remote services with a user's data,
software and computation.
WHAT IS CLOUD COMPUTING?
End users access cloud-based applications
through a web browser or a light-weight desktop or
mobile app
Sharing of resources to achieve coherence over a
network
SERVICE MODELS
(IaaS)Infrastructure
as a service
(PaaS)Platform as a
service
(SaaS)Software as a
service
(NaaS)Network as a
service
INFRASTRUCTURE AS A SERVICE (IAAS)

Not manage the cloud
infrastructure and platform
where the application runs
NETWORK AS A SERVICE (NAAS)
Optimization of resource allocations by
considering network and computing
resources as a unified whole

LOOKING TO THE FUTURE
CLOUD STORAGE
a model of online storage connected through
the internet
 a virtualized pools of Storage allowed end
users to access and manage the data in the
storage.

CLOUD STORAGE
- Physically, the resource may span across multiple
servers
-Cloud storage can be easily accessed via
• a web application Programming Interface (API)
• a gateway of cloud storage
• a Web-based user-interface(UI)
ADVANTAGES
• Reduce the expenses of buying new physical
data storage
• Outsource the storage maintenance to service
providers
• Access flexibly to the online data storage
everywhere
THREATS
• Attack surface area
• Security
• Supplier stability
GOOGLE DRIVE
• Released on April 24, 2012
• providing storage and synchronization
service
• Enabling user own cloud storage, file
sharing and live editing
FEATURES OF GOOGLE DRIVE
• Create new documents and presentations instantly
• Enable Users to share files with anyone, and control
others’ authorities to view, edit the files
•Integration of Google Drive and Gmail
1. Send the link of the file storing in Google Drive
via Gmail and
2. Allow everyone to have the same file
3. Keep Tracking every changes users make
**Some of those function are created by using Cloud
computing technologies
CLOUD COMPUTING
a model enabling convenient, on-demand
network access to a shared anywhere.
 configurable computing resources

 (e.g.
networks, servers, storage, applications, and
services)

provisioned and released rapidly with minimal
management efforts or interaction with service
providers.
CLOUD COMPUTING

Promotes availability

5 essential characteristics

3 service models

4 deployment models
FIVE ESSENTIAL CHARACTERISTICS
1. On demand self-service
 Can
2.
unilaterally configure computing capabilities
Broad network access
 Available
over network and stopped through
mobile phones, laptops and PDA.
FIVE ESSENTIAL CHARACTERISTICS
4. Resource pooling

The computing resources of providers are pooled to serve different
consumers with multi-tenant model.
5. Rapid


Capabilities can be rapidly and easily provisioned
Consumer can purchased at any time.
6. Measured Service

Cloud systems can automatically control and optimize the
resources used by leveraging a metering capability.
Three service models
SERVICE MODELS

Application
Software as a Service(SaaS)
 Provider’s apps running on a cloud infrastructure
 The apps are accessible to various client devices.
 No need to manage or control the underlying the
cloud infrastructure (eg. Networks, servers, OS )
 Except limited user-specific apps configuration
settings

SERVICE MODELS

Platform
 Platform
as a Service (PaaS)
 Consumer-
create by using programming languages
and tools which are supported by the providers.
 No
need to manage the underlying the cloud
infrastructure (eg. Networks, servers, OS )
SERVICE MODELS

Infrastructure
 Infrastructure
 Able
as a Service (IaaS)
to deploy and run arbitrary software (eg. OS &
apps)
 No
need to manage or control the cloud
infrastructure (eg. Networks, servers, OS )
FOUR DEPLOYMENT MODELS

Private cloud
 Is

Community cloud
 Is

operated solely for an organization
shared by several organizations
Public cloud
 General

public
Hybrid cloud
A
composition of two or more clouds
COMMON EXAMPLES OF CLOUD COMPUTING
CLOUD COMPUTING VS CLOUD STORAGE
Cloud Computing:
-Providing Computing services for the end users
*Software can execute in the Virtual platform constructed
by the infrastructure.
Cloud Storage
-Providing Storage as a service for the end users
*Software can NOT execute in the Virtual Platform.
