This document discusses collaboration in multi-cloud environments. It introduces cloud computing and the types of cloud services. The objective is to enable collaboration across multiple clouds. Currently, interacting with each cloud individually is difficult due to heterogeneity, tight coupling, and lack of preexisting agreements. The document proposes a system of proxies that act as edge nodes to overcome these restrictions and enable collaboration in a multi-cloud environment. It outlines the modules, hardware, software, and technical requirements for such a proxy-based collaboration system.

2. 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)

3. Types of clouds:
 Hybrid cloud
 Private cloud
 Public cloud
Community cloud

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

5. Objective:
Providing Collaboration in Multi-cloud

6. 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 lowlevel, tightly controlled and constraining integration
techniques.

7. Disadvantages:
The following are the restrictions:
 Heterogeneity and tight coupling.
 Preestablished business agreements.
 Service delivery model.

8. Proposed System:
• I propose network of proxies to overcome these
restrictions
 Proxy is an edge-node-hosted software instance.

9. Cloud-hosted proxy:

10. Proxy as a Service:

11. On-premises proxy:

12. Modules:
Collaboration Framework for multi cloud system
Module.
Client/Users Module.
Cloud Service Provider Module.
Proxy Service Provider Module.
