Towards Trustworthy Multi-Cloud Services Communities:

A Trust-based Hedonic Coalitional Game

Abstract

The advent of cloud computing has led to a rapid increase in thenumber of Web services that are deployed in cloud data centers.

Existing system

The prominence of cloud computing led to unprecedented proliferation in the number of Web services deployed in clouddata centers. In parallel, service communities have gained recently increasing interest due to their ability to facilitate discovery,composition, and resource scaling in large-scale services’ markets. The problem is that traditional community formation models may

work well when all services reside in a single cloud but cannot support a multi-cloud environment. Particularly, these models overlookhaving malicious services that misbehave to illegally maximize their benefits and that arises from grouping together services owned bydifferent providers. Besides, they rely on a centralized architecture whereby a central entity regulates the community formation; whichcontradicts with the distributed nature of cloud-based services.

Disadvantages

1. Security is less.

Proposed system

We propose a three-fold solution that includes: trustestablishment framework that is resilient to collusion attacks that occur to mislead trust results; bootstrapping mechanism thatcapitalizes on the endorsement concept in online social networks to assign initial trust values; and trust-based hedonic coalitionalgame that enables services to distributively form trustworthy multi-cloud communities. Experiments conducted on a real-life datasetdemonstrate that our model minimizes the number of malicious services compared to three state-of-the-art cloud federations andservice communities models.

Advantages

1. Security is more.
