One of the solution is </p><p>using cloud computing Infrastructure as a Service (IaaS) </p><p>for community resources sharing. In this research, </p><p>implementation cloud computing by using proxmox that </p><p>is an open source operating system with the </p><p>infrastucture system of IaaS includes CPU, memory, </p><p>hardisk, and Networks management. IaaS in proxmox </p><p>using virtual server technology so that utility of the </p><p>server hardware will be share between many system </p><p>operating system (OS) that are installed inside. Proxmox </p><p>server virtual machine can execute many OS running </p><p>such as linux and Microsoft windows that are having </p><p>good evidence for active running simultaneously. </p><p>Keywords: Cloud Computing, Infrastructure as </p><p>a Service, proxmox </p><p>I. INTRODUCTION Cost for hardware requirements for the </p><p>information technology implementation are not </p><p>cheap, among the major components needed are the </p><p>services server, storage, operating system and internet </p><p>network. Also, for the installation and maintenance </p><p>need any special management organization which not </p><p>all organization can provides human Resources to </p><p>manage it. Of course it required technological </p><p>solutions that allow for the sharing of information </p><p>technology resources for the community that are </p><p>needed to implement information technology. </p><p>To overcome these problems, they can utilize </p><p>cloud computing technology to meet the </p><p>infrastructure needs without the need for </p><p>infrastructure investment independently and expert </p><p>resources to manage and maintaince. Cloud is able to </p><p>provide basic information technology resources, that </p><p>are include storage, power processing, memory, </p><p>operating system, and also computer networking </p><p>which can be used by users of cloud clients to run </p><p>they owned applications by maximizing utility of </p><p>existing infrastructures that are provided by third </p><p>party vendors. </p><p>Cloud computing has become the trend of the </p><p>implementation of the current resource sharing, Cloud </p><p>itself is defined as a cutting edge system of parallel </p><p>and distributed computing which is consisting of a </p><p>collection of inter-connected and virtualized </p><p>computers that are dynamically provisioned and </p><p>represented through the Service Level Agreement </p><p>(SLA) [1]. The scope of the cloud cover include </p><p>Software as a Service (SaaS), Platform as a Service </p><p>(PaaS) and Infrastructure as a Service (IaaS) [2]. </p><p>SaaS is an application component that is built </p><p>from the composition of services trough the same or </p><p>different. Amongs SaaS that are familiar used by </p><p>public internet user through the web presentation and </p><p>they service sharing. Service providers that are </p><p>include this area are Gmap, GDocs, Flickr, Youtube, </p><p>Facebook, Amazon e-Commerce, Twitter, and others. </p><p>Through application programmable interface (API) </p><p>and web service, services from the provider can be </p><p>use-recycled easily. </p><p>PaaS is a platform application development </p><p>engine with a high level abstraction to be able to </p><p>produce efficient and reliable service. PaaS have a </p><p>support component library that allows developers to </p><p>easily implement enterprise systems likely </p><p>programming language Ruby, Java EE, Grails, .Net, </p><p>Python, PHP and others. Google's cloud provides </p><p>PaaS supporting for virtually all programming </p><p>languages including library supporters. </p><p>Focused on IaaS There are three types of cloud </p><p>computing service are clasified of public services, </p><p>private, and community. A public cloud is one which </p><p>the services and infrastructure are provided off-site </p><p>over the internet by service provider. These clouds </p><p>offer the greatest level of efficiency in shared </p><p>resources because user client only focus on their </p><p>business process operasional without maintaince </p><p>mailto:hermawan.unijoyo@yahoo.co.idmailto:fsholihin@gmail.commailto:khamdi_m@yahoo.commailto:mulaab@trunojoyo.ac.id</p></li><li><p>SEMINAR ON ELECTRICAL, INFORMATICS, AND ITS EDUCATION 2013 </p><p>B - 24 </p><p>hardware, software and data storage. Google cloud, </p><p>Amazon, Rackspace is amongs vendor that provide </p><p>public service. </p><p>A private cloud is one in which the services </p><p>and infrastructure are maintained on a private </p><p>Management and commonly running in a private </p><p>network. But as cloud all infrastructure still provide </p><p>by third party vendor which reduces the cost savings </p><p>and minimizing maintainance requirements. On this </p><p>type client will have own self responsebility on </p><p>security and data privacy. </p><p> While the latter type of Cloud Computing is </p><p>the type of cloud community. On this type of services </p><p>aimed at specific communities both in the provision, </p><p>management until using for common interest. So that </p><p>in this type there is a specification that provides a </p><p>wide space for organizations and corporations to </p><p>develop what they need [3]. For the community cloud </p><p>resource sharing, existing infrastructure and also data </p><p>that can be managed with together. The community </p><p>cloud more appropriate to be applied to communities </p><p>that have the same scope and interest. </p><p>Therefore in this research study design and </p><p>implementation of cloud services community defined </p><p>to the implementation of the education community </p><p>which is in the region of Madura by making the </p><p>Trunojoyo University as a provider of cloud services </p><p>within corporate with education authorities and </p><p>schools. </p><p>II. METHODS For the implementation of the education </p><p>community cloud is needed in the design and </p><p>implementation phases, as well as through the </p><p>following steps: </p><p>Preparation of cloud community regulatory Overshadowing regulatory cooperation </p><p>between community organizations in the cloud </p><p>requires a mutual agreement in policy, financing and </p><p>maintenance of the system to be built. In the cloud </p><p>community Which was built have work agreement for </p><p>the expansion of educational technology for the </p><p>education Community between Trunojoyo University </p><p>as a service provider with the Department of </p><p>Education and the Department of Religious Affairs </p><p>Bangkalan. </p><p>Research of Cloud Technology fo Community </p><p>Provider To meet the information Technology that is </p><p>needed by community, research is needed in meeting </p><p>the needs of software and hardware. Meeting the </p><p>needs of software development conducted with the </p><p>research at the level of SaaS and PaaS cloud </p><p>components whithin produce Products of a website </p><p>portal that manage internal management requirement </p><p>of education departemen and distributed website of </p><p>school agencies like is show in the Figure 1 and </p><p>Figure 2. </p><p> Figure 1.
