Present Financial crisis in Higher Educational Institutes (HEIs) facing lots of problems considerable budget cuts, make difficult to meet the ever growing IT based research and learning needs, institutions are rapidly planning and promoting cloud based approaches for their academic and research needs. A cost effective Hybrid Cloud framework for HEI’s will provide educational services for campus or intercampus communication. Hybrid Cloud Framework comprises Private and Public Cloud approaches. This paper will propose the framework based on the Open Source Cloud (OpenNebula for Virtualization, Eucalyptus for Infrastructure and Aneka for programming development environment) combined with CSP’s services which are delivered to the end-user via the Internet from public clouds: Google, Microsoft, Zoho, Salesforce etc.

Research Objectives and Core Themes
The primary objective of this paper is to propose a cost-effective Hybrid Cloud framework designed for Higher Educational Institutes (HEIs) to facilitate academic and research activities, especially in light of global financial constraints. The study addresses the challenge of meeting increasing IT infrastructure demands by integrating private and public cloud models to optimize resource availability and reduce operational costs.
- Architectural design for campus-based hybrid cloud environments.
- Integration of open-source cloud technologies like OpenNebula, Eucalyptus, and Aneka.
- Leveraging Cloud Service Provider (CSP) offerings for educational services.
- Strategy for intercampus communication and resource sharing.
- Mitigation of high IT infrastructure maintenance and energy costs.
Excerpt from the Book
III. Hybrid Cloud for HEI’s of Pakistan
The hybrid cloud framework used to serve the current IT infrastructure for educational institutions services. The three tier architecture distributing the service platforms to enabling the users logon at a single machine (see figure: 2). Tier one performing user access operations (i.e. Authentication, proxy, Data storage), Cloud controllers combines approaches public cloud, Eucalyptus open source cloud provides architecture to manage such services. This allows enterprise products and support. Eucalyptus Components [9] are: Cloud controller, Node controller, Storage controller. Linking open-source software framework that implement on (SaaS) model.
Tier two would be intermediate model which facilitate developers to use programming APIs, scripting and programming languages, Web 2.0/3.0 and interconnecting public cloud APIs Google AppEngine and Sun's Cloud API and Microsoft's Azure Services. The Cloud layer represented as Platform as a Service (PaaS). Aneka cloud platform gives ability to developers the ability to run their own programming applications [10] and deployed on the Cloud, also denoted as Platform as a Service (PaaS).
Tier three Infrastructure as a Service (IaaS) would support Virtualization and VM management and development platform. The OpenNebula open source cloud managing virtual infrastructure for heterogeneous data center to build public, private and hybrid cloud resources. OpenNebula combines network, storage, virtualization, security and monitoring services to deploy multi-tier technologies. It also emphases interoperability, standardization and portability.

Frequently Asked Questions
What is the primary focus of this paper?
The paper focuses on designing a cost-effective Hybrid Cloud framework specifically tailored for Higher Educational Institutes (HEIs) to improve resource sharing and reduce IT infrastructure costs.
What are the central thematic areas covered?
The core themes include the adoption of cloud computing in academia, the architectural layers of hybrid clouds (SaaS, PaaS, IaaS), and the integration of open-source technologies for campus-wide services.
What is the main goal or research question?
The goal is to propose a technical framework that enables universities to overcome budget cuts and meet growing IT research and learning needs by combining private and public cloud capabilities.
Which scientific methods are utilized?
The paper utilizes a constructive approach by proposing a three-tier architecture that integrates specific open-source components (OpenNebula, Eucalyptus, Aneka) with public cloud APIs to create a functional hybrid environment.
What is the content of the main section?
The main section describes the three-tier framework, the specific role of various controllers and software layers, and the practical implementation considerations for higher education administrators.
Which keywords characterize this work?
Key terms include Hybrid Campus Cloud, Higher Educational Institutes, Open Source, and virtualization within an educational context.
How does the proposed framework handle user authentication and access?
Tier one of the proposed architecture is dedicated to user access operations, including authentication, proxy services, and centralized data storage.
What specific open-source software is recommended?
The paper explicitly recommends OpenNebula for virtualization, Eucalyptus for infrastructure management, and Aneka for the programming development environment.
Why is a hybrid approach specifically suggested for HEIs?
A hybrid approach is suggested because it provides the flexibility of private control for secure, localized tasks while allowing institutions to offload resource-heavy or collaborative tasks to public cloud providers.
