Collaboration in Multi cloud computing Environments Framework

and Security issues

Introduction to Cloud Computing:Cloud computing is an environment where the

computing resources are outsource as a service through the internet.

Services of cloud computing: I as S(Infrastructure as a service) P as S(Platform as a service) S as S(Software as a service)

Types of clouds:

Hybrid cloud Private cloud Public cloudCommunity cloud

What is Collaboration?

Collaboration is a new emerging way of sharing and co-authoring computer files through the use of cloud computing.

Objective:Providing Collaboration in Multi-cloud

Current Environment:A client that wishes to simultaneously use

from multiple clouds must individually interact with each cloud service gather intermediate results process the collective data and generate final results.

cloud mashups require pre established agreements among providers as well as the use of custom-built, proprietary tools that combine services through low-level, tightly controlled and constraining integration techniques.

Disadvantages:The following are the restrictions:

Heterogeneity and tight coupling. Preestablished business agreements. Service delivery model.

Proposed System:

• I propose network of proxies to overcome these restrictions

Proxy is an edge-node-hosted software instance.

Cloud-hosted proxy:

Proxy as a Service:

On-premises proxy:
