Cloud computing is said to be the next big thing in the computer world after the internet. Cloud computing is the use of the Internet for the tasks performed on the computer and it is visualized as the next- generation architecture of IT Enterprise. The ‘Cloud’ represents the internet. Cloud computing is related to several technologies and the convergence of various technologies has emerged to be called cloud computing.Open source systems refer to software systems whose source code is available, allowing for immediate incorporation of improvements and adaptations of the system by its users. This seminar reports on an evaluation of open source management tools for cloud computing. Cloud computing is not a magical solution, planning and management of resources and the cloud in itself is pivotal. In this report, we compare and evaluate a number of open source tools used in the industry to manage and automate the cloud. We evaluate provisioning tools, orchestration tools, configuration tools and monitoring tools. Keyword: management of cloud with open source tools. I. INTRODUCTION Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualized resources. It is a Cloud computing is the delivery of computing as a byproduct and consequence of the ease-of-access to remote service rather than a product, whereby shared resources, computing sites provided by the Internet. This may take the software, and information are provided to computers and form of web-based tools or applications that users can other devices as a utility (like the electricity grid) over a access and use through a web browser as if the programs network (typically the Internet). were installed locally on their own computers. Cloud computing is an emerging computing technology Cloud computing providers deliver applications via the that is rapidly consolidating itself as the next big step in the internet, which are accessed from web browsers and desktop development and deployment of an increasing number of and mobile apps, while the business software and data are distributed applications. stored on servers at a remote location. Open source refers to any software system whose source Cloud computing is built upon the broader concept of code is made available for use or modification by third-party converged infrastructure and shared services. This type of developers. Thus, unlike centralized, proprietary software data center environment allows enterprises to get their development models, open source practical accessibility to applications up and running faster, with easier the source code, allowing for immediate and concurrent manageability and less maintenance, and enables IT to more incorporation of different approaches, and eventually, the rapidly adjust IT resources (such as servers, storage, and branching of the system into customized variants. networking) to meet unpredictable business demand. Most Merging these two trends leads to a new breed of tools: cloud computing infrastructures consist of services delivered Open source cloud computing tools (OSCCT). These tools through shared data-centers and appearing as a single point provide a free, customizable infrastructure to deploy clouds of access for consumer's computing needs.

WHAT IS CLOUD COMPUTING? Cloud computing is a marketing term for technologies that provide computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. A parallel to this concept can be drawn with the electricity grid, where in end-users consume power without needing to understand the component devices or infrastructure required to provide the service. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Figure 1: Cloud Computing Layers © 2010, IJARCS All Rights Reserved CONFERENCE PAPE R 88 “A National Level Conference on Recent Trends in Information Technology and Technical Symposium” On 09th March 2013 Organized by Dept. of IT, Jawaharlal Darda Inst.
