PROBLEM STATEMENT

• Dealing with “single cloud” providers is predicted to becomeless popular with customers due to risks of service availabilityfailure and the possibility of malicious insiders in the singlecloud.

• A movement towards “multi-clouds”, or in other words,“interclouds” or “cloud-of-clouds” has emerged recently.

WHAT IS CLOUD COMPUTING ?

• Cloud computing is a model for enabling ubiquitous(present),convenient, on-demand network access to a shared pool ofconfigurable computing resources (e.g., networks, servers,storage, applications, and services) that can be rapidlyprovisioned and released with minimal management effort orservice provider interaction.

• This cloud model is composed of five essential characteristics,three service models, and four deployment models.

DIFFERENCE BETWEEN TRADITIONAL DATA CENTER AND CLOUD COMPUTING SERVICES

Traditional Data Services:-

-Proprietary Customize

-More Secure

-Economy of Scale: Organization

-Dedicated

Cloud Computing Services:-

-Standardized

-Secure

-Economy of Scale: Ecosystem

-Share

MOVING TO CLOUDS

4/10/2015Sinhgad Institute of Technology , Lonavala 8

• Data is moving to the cloud

• Main reason: costs (pay-per-use model)

EVERYTHING CONNECTED TO CLOUD

EXISTING SYSTEM

• Cloud providers should address privacy and security issues as amatter of high and urgent priority.

• Dealing with “single cloud” providers is becoming less popularwith customers due to potential problems such as serviceavailability failure and the possibility that there are maliciousinsiders in the single cloud.

• Byzantine Protocol

DISADVANTAGES OF EXISTING SYSTEM

Cloud providers should address privacy and security issues as amatter of high and urgent priority.

Service availability failure and the possibility that there aremalicious insiders in the single cloud.

PROPOSED SYSTEM

• This Project focuses on the issues related to the data securityaspect of cloud computing.

• Moving towards “Cloud of clouds “ or multi clouds techniquewhich improves

Better read performance

Data corruptions'

Reduces Intrusions ….etc

ADVANTAGES OF PROPOSED SYSTEM

DepSky System:Multicloud model

Shamir’s Secret sharing algorithm

The user runs custom applications using the service provider’sresources

Cloud service providers should ensure the security of theircustomers’ data and should be responsible if any security riskaffects their customers’ service infrastructure.

CONCLUSION

• It is clear that although the use of cloud computing has rapidlyincreased, cloud computing security is still considered the majorissue in the cloud computing environment.

• Customers do not want to lose their private information as aresult of malicious insiders in the cloud. In addition, the loss ofservice availability has caused many problems for a largenumber of customers recently

FUTURE ENHANCEMENTS

For future work, we aim to provide a framework to supply a secure cloud database that will guarantee to prevent security risks facing the cloud computing community.

This framework will apply multi-clouds and the secret sharing algorithm to reduce the risk of data intrusion and the loss of service availability in the cloud and ensure data integrity.
