Eucalyptus - Installation Manual
Eucalyptus - Installation Manual Hannes Gamper and Tomi Pievil¨ainen December 3, 2009, Espoo Contents 1 Introduction 1 2 Requirements 1 3 Installation procedure 2 3.1 Install Ubuntu 9.10 Server edition and Ubuntu Enterprise Cloud . 2 3.2 Step 1 - Prerequisites . 2 3.3 Step 2 - System Installation and Configuration . 2 3.4 Step 3 - Registering UEC Components . 3 3.5 Step 4 - Initial Login . 3 1 Introduction Cloud computing systems provide users with access to large amounts of computational resources and data [4]. Virtualisation is used to hide information like physical location and architectural details of the resources from the user. Eucalyptus is an open-source software framework for cloud computing implementing Infrastructure as a Service (IaaS). It is tailored for the use in the research community. Users can run and control virtual machine instances on a variety of physical resources found within academic settings. 2 Requirements Eucalyptus can be installed via the Ubuntu Enterprise Cloud, introduced in Ubuntu 9.04 [3]. The following installation instructions are based on Ubuntu 9.10 Server edition. In terms of hardware requirements recommended minimum specification is a a dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. 1 3 Installation procedure • Ubuntu 9.10, server edition • dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. • port 22 needs to be open for admins (for maintenance) • port 8443 needs to be open for users for controlling and sending requests to the cloud via a web interface 3 Installation procedure The installation instructions in this manual closely follow those given on the \Ubuntu Enterprise Cloud" homepage [2], with some remarks regarding installation from scratch via the Ubuntu 9.10 server edition. -
A Survey of Collaborative Tools in Software Development
1 INTRODUCTION A Survey of Collaborative Tools in Software Development Anita Sarma Institute for Software Research Donald Bren School of Information and Computer Sciences University of California, Irvine [email protected] ISR Technical Report # UCI-ISR-05-3 March 22, 2005 1 Introduction Collaboration is at the heart of software development. Virtually all software devel- opment requires collaboration among developers within and outside their project teams, to achieve a common objective. It has in fact been shown that about 70% of a software engineer’s time is spent on collaborative activities [219]. Indeed, col- laboration in software development has been studied by researchers in the fields of Software Engineering and Computer Supported Cooperative Work (CSCW) since the 1980s and has produced a wide range of collaborative tools. Enabling software developers to collaborate effectively and effortlessly is a difficult task. The collaboration needs of the team depend to a large extent on environmental factors such as, the organizational structure of the team, the domain for which the software is produced, the product structure, and individual team members. Accordingly, research in collaborative development has produced a host of tools, each typically focussing on a different aspect of collaboration. Most teams have their favorite repertoire of tools that has been built from historical use. These tools may not always be the best suited for the team, but the team still uses them nevertheless as the inertia and cost of trying out new tools surpasses the benefits. A number of classification frameworks exist that can be used to classify collaborative tools. In addition to placing the various tools in context, developers can use these frameworks to select the right mix of tools fit for their needs. -

A Comparative Study of Current Open-Source Infrastructure As a Service Frameworks
A Comparative Study of Current Open-source Infrastructure as a Service Frameworks Theo Lynn, Graham Hunt, David Corcoran, John Morrison and Philip Healy Irish Centre for Cloud Computing, Dublin 9, Ireland Keywords: Cloud Computing, Open Source, IaaS, Openstack, Cloudstack, Opennebula, Eucalyptus. Abstract: With the growth of cloud computing in recent years, several commercial and open source IaaS frameworks have emerged. The development of open source IaaS solutions offers a free and flexible alternative to commercial cloud services. The main contribution of this paper is to provide a qualitative comparative of current open-source IaaS frameworks. Existing research papers examining open source IaaS frameworks have focused on comparing OpenStack with a small number of alternatives. However, current research fails to adequately compare all major open source frameworks in a single study and notably lacks the inclusion of CloudStack. Our research paper provides the first overview of the five main open source cloud IaaS frameworks – OpenStack, CloudStack, OpenNebula, Eucalyptus and Nimbus. As such, this review provides researchers and potential users with an up to date and comprehensive overview of the features of each solution and allows for an easy comparison between the open source solutions. 1 INTRODUCTION the freedom to modify the source code and build a cloud that is pluggable and open to extensions while Cloud Computing technologies have seen significant reducing costs and avoiding vendor lock-in (Zhang adoption in recent years by enterprises, researchers et al., 2013; Wen et al. 2012; Bist et al., 2013).

Appscale: Open-Source Platform-As-A-Service
AppScale: Open-Source Platform-As-A-Service Chandra Krintz Chris Bunch Navraj Chohan Computer Science Department University of California Santa Barbara, CA USA UCSB Technical Report #2011-01 January 2011 ABSTRACT In this paper we overview AppScale, an open source cloud platform. AppScale is a distributed and scalable cloud runtime system that executes cloud applications in public, private, and hybrid cloud settings. AppScale implements a set of APIs in support of common and popular cloud services and functionality. This set includes those defined by the Google App Engine public cloud as well as those for large-scale data analytics and high-performance computing. Our goal with AppScale is to enable research and experimentation into cloud computing and to facilitate a ``write once, run anywhere'' programming model for the cloud, i.e., to expedite portable application development and deployment across disparate cloud fabrics. In this work, we describe the current AppScale APIs and the ways in which users can deploy AppScale clouds and applications in public and private settings. In addition, we describe the internals of the system to give insight into how developers can investigate and extend AppScale as part of research and development on next-generation cloud software and services. INTRODUCTION AppScale is a scalable, distributed, and fault-tolerant cloud runtime system that we have developed at the University of California, Santa Barbara as part of our research into the next generation of programming systems (Chohan, et al., 2009; Bunch, et al., 2010; Bunch (2) et.al, 2010). In particular, AppScale is a cloud platform, i.e. a platform-as-a-service (PaaS) cloud fabric that executes over cluster resources.
