CCOA: CLOUD COMPUTING OPEN

ARCHITECTURE

ABSTRACT

Main Objective is Sharing of resources

Sharing of resources include Infrastructures,

Software, Applications, Business Process

CC platforms formally not adapted SOA(Service

Oriented Architecture)

Open Architecture presents customizable CC


4/21


ARCHITECTURE

INRODUCTION

Major objective is to leverage Internet or Intranet

provision resources to users

CC provides environments to enable resource

sharing in terms of

Scalable Infrastructures

Middleware & Application DevelopmentPlatforms

Value-added business applications


5/21


ARCHITECTURE

OSI Model for CC

3 Objectives helps in defining a good Open

Architecture for CC

To articulate a reusable way of creating scalable

and configurable provisioning platform

To propose a set of common and shared services

for building CC platforms To maximize the potential business value of CC

SEVEN PRINCIPLES OF CC

ARCHITECTURE

1.Integrated Ecosystem Management for

Cloud

Ecosystem includes Vendors, Partners, End Users

Cloud Vendors expose its interaction interfaces

Cloud Partners provides components to vendors

Cloud Clients are users of Cloud Services

ARCHITECTURE

2.Virtualization and Cloud Infrastructure

Two basic approaches for enabling virtualization

Hardware Virtualization- To manage hardware

equipments in plug-and-play mode.

Software Virtualization- Enable the Software

sharing.

ARCHITECTURE

3.Service-Orientation for Common Reusable

Services

There are two major types of common reusable

services

Cloud Horizontal Business Services- Hide the

complexities of middleware, database and tools.

Cloud Vertical Business Services- Domainspecific or industryspecific utility services.

ARCHITECTURE

4.Extensible provisioning and Subscription

for Cloud

It is a unique feature of Cloud Computing System.

This implies the service provisioning architecture for

free-use users, paying users.

It addresses a key question ofhow to handle serviceproviders.

ARCHITECTURE

5.Configurable Enablement for CloudOfferings

All cloud offerings should address certain business

goals. CCOA defines offering aspects at four levels:

Infrastructure as a Service

Software as a Service(SaaS)

Application as a Service

Business Process as a Service

ARCHITECTURE

6.Unified Information Representation and

Exchange Framework

Information Representation and Message Exchange

of CC resources are very important to enable

collaborative and effective features of CC.

Modules in cloud represents cloudentities.

Messages exchanged between cloud entities formMessage Exchange Patterns.


12/21


ARCHITECTURE

7.Cloud Quality and Governance

This is responsible for the Identification and

Definition of quality indicators for CC environment

This also set a normative guidance to govern the

Design

Deployment

Operation

Management

CASE STUDIES OF CCOA

1.Infrastructure Cloud

We build our own private cloud to enable computing

resource sharing.

This offer service requesters a pay-to-use model to

provide servers with a selected set of preinstalled

packages.

By this time is shortened for production based onrequest submissions.


14/21

CASE STUDIES OF CCOA

2.Business Cloud

Here it covers all the scenarios of business process as

a service in CC environment.

A lot of scenarios requires human intelligence to

analyze the summary report by validating the

findings and regenerate a report


15/21

CLOUD COMPUTING IN SYSTEM

ARCHITECTURE

System Architecture is the collection of independent

components that are connected or interacted

through well defined connectors.

One component can interact with another set ofdefined agreements.

Enterprise Architecture is a kind of architecture in

which there are collections of enterprises as

components and the interrelation among them as

connectors.

CLOUD COMPUTING

SECURITY ISSUES

1. Security -how secure the data are?

2. Privacy -does cloud provides piracy?

3. Reliability -does fluctuations resist?

4. Legal Issues -are the data confidential?

5. Open Standard -helps in critical growth of CC

6. Compliance -can sustain readily change?

7. Freedom -users shouldnt possess data

8. Long-term Viability -can recover its potentiality?


17/21

SOLUTION

Encrypt the data with your own keys and make surethat a vendor is ready for security certifications andexternal audits.

Identity management, access control, reporting ofsecurity incidents, personnel and physical layermanagement should be evaluated before youselect.

Organizations need to run applications and datatransfer in their own private cloud and thentransmute it into public cloud.

19/21

CONCLUSION

We have proposed the CCOA based on Seven

Architectural Principles, by Integrating power of SOA

and Virtualization Technology of Hardware and

Software.The case studies have shown that proposed

CCOA is an extensible and configurable architecture

for providing normative guidance and enabling

Infrastructure, Software, Application, and BusinessProcess Sharing in a unified manner with enough

security provided.
