Introduction Cloud Storage Cloud Computing Future Development of Cloud service Application of Cloud in HKBU

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)

Background

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.

- 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)

CLOUD STORAGE

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 file3. 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 CHARACTERISTICS1. On demand self-service

Can unilaterally configure computing capabilities

2. 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 as a Service (IaaS)

Able 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 operated solely for an organization

Community cloud Is shared by several organizations

Public cloud General public

Hybrid cloud A composition of two or more clouds

COMMON EXAMPLES OF CLOUD COMPUTING

Web-basedNative

Software-based

PHP-based

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.

Advantages:1. Reduce the money

spend on buy new hardware, software for each computer in BU.

2. Students can use their own customized OS and software to for their works in BU.
