Easing Scientific Computing and Federated Management in The
Easing Scientific Computing and Federated Management in the Cloud with OCCI Zdenekˇ Sustrˇ 1, Diego Scardaci2,3, Jirˇ´ı Sitera1, Boris Parak´ 1 and V´ıctor Mendez´ Munoz˜ 4 1Department of Distributed Computing, CESNET, Zikova 4, 160 00, Praha 6, Czech Republic 2European Grid Initiative, Science Park 140, 1098 XG Amsterdam, Netherlands 3INFN Sezione di Catania, Via S. Sofia 64, I-95123 Catania, Italy 4Computer Architecture & Operating Systems Department (CAOS), Universitat Autonoma` de Barcelona (UAB), Bellaterra, Spain Keywords: Federated Cloud, Cloud Standards, Cloud Interoperability, Cloud Solution Design Patterns, Cloud Application Architectures, Cloud Middleware Frameworks, Open Cloud Computing Interface. Abstract: One of the benefits of OCCI stems from simplifying the life of developers aiming to integrate multiple cloud managers. It provides them with a single protocol to abstract the differences between cloud service implemen- tations used on sites run by different providers. This comes particularly handy in federated clouds, such as the EGI Federated Cloud Platform, which bring together providers who run different cloud management plat- forms on their sites: most notably OpenNebula, OpenStack, or Synnefo. Thanks to the wealth of approaches and tools now available to developers of virtual resource management solutions, different paths may be cho- sen, ranging from a small-scale use of an existing command line client or single-user graphical interface, to libraries ready for integration with large workload management frameworks and job submission portals relied on by large science communities across Europe. From lone wolves in the long-tail of science to virtual or- ganizations counting thousands of users, OCCI simplifies their life through standardization, unification, and simplification.

D1.3 Production System
REPORT FOR DELIVERABLE D1.3 1 1 INTRODUCTION This report provides an overview of the technical characteristics and functionality of deliverable D1.3 “Production System”. Its purpose is to provide a short introduction to the processes designed and implemented enabling the final production installation (g eodata.gov.gr) of the various software developed and reused by PublicaMundi . The reader is encouraged to visit the software’s repository (https://github.com/PublicaMundi) to receive: Up-to-date versions of the software, along with documentation targeted to developers Detailed information regarding all development effort (commits, activity, issues) Instructions regarding the installation of the software and its dependencies 2 2 DESCRIPTION OF TASK PublicaMundi aims to make open geospatial data easier to discover, reuse, and share by fully supporting their complete publishing lifecycle in open data catalogues. To achieve this, we are extending and integrating leading open source software for open data publishing and geos patial data management. The goal of Task 1.3 is to apply agile development principles with periodic integration in order to maintain relevant contributions. Integration is performed on labs.geodata.gov.gr, a beta-testing facility, where new functionalities are tested on real data and users. New versions are being deployed automatically and user feedback is collected with online tools bringing them in contact with developers. For the purposes of our production deployment, we built upon our first deployment of labs.geodata.gov.gr, extending our integration environment (D1.2) and through automation procedures we established the production environment. On this environment, a stable version of the software has been rolled out, after extensive testing of the components of PublicaMundi.

Volume 8, No. 1, Jan-Feb 2017 ISSN No. 0976-5697 International Journal of Advanced Research in Computer Science RESEARCH PAPER Available Online at www.ijarcs.info Cloud Computing: A Perspective Approach Sharda Rani Assistant Professor Deptt of Computer Science R.K.S.D. College, Kaithal, India Abstract- Cloud service models are infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Network as a Service (NaaS). Cloud deployment models are public cloud, private cloud, community cloud, and hybrid cloud. Cloud enables use of resources as per payment. It uses several technologies such as virtualization, multi-tenancy, and webServices. OpenStack is open source software to implement private and public cloud. It provides IaaS. This paper is a step towards alleviating efforts of setting up a private cloud. This OpenStack based implementation uses hardware assisted virtualization, logical volume management, and network interface card in promiscuous mode. Hardware assisted virtualization offers better performance. Logical volume management provides flexibility to file system expansion. Keystone, glance, cinder, quantum, and horizon services are grouped for one node, named controller node. Keyword: Cloud infrastructure, virtualization, openstack, Service Models of Cloud. These are four service models of cloud: Infrastructure as a I. INTRODUCTION Service, Platform as a Service, Software as a Service, and Cloud derives its name from the cloud shaped symbol Network as a Service. Figure 1 demonstrates the abstraction representing Internet, as it is used as an abstraction for its level of services. Software as a service is taken place at the complex infrastructure .Cloud computing is the use of the top.

UNIVERSITY OF BANJA LUKA FACULTY OF ELECTRICAL ENGINEERING MIHAJLO SAVIĆ COMPUTER INFRASTRUCTURE AS A SERVICE MONITORING SYSTEM DOCTORAL DISSERTATION BANJA LUKA, 2020 INFORMACIJE O MENTORU I DISERTACIJI Mentor: prof. dr Zoran Jovanović, redovni profesor, Elektrotehnički fakultet Beograd Naslov doktorske disertacije: SISTEM ZA NADZOR RAČUNARSKE INFRASTRUKTURE KAO SERVISA Rezime: Disertacija predstavlja rezultat istraživanja u oblasti nadzora distribuirane i heterogene računarske infrastrukture sa posebnim osvrtom na računarsku infrastrukturu kao servis. Nakon opisa oblasti i pregleda dostupnih rješenja, izvršena je analiza zahtjeva koje mora da ispuni novi sistem za nadzor. Na osnovu podataka prikupljenih u toku VI-SEEM projekta koji je obuhvatao računarsku infrastrukturu u 16 država regiona, definisane su tri oblasti primjene sistema za nadzor: računarska infrastruktura kao servis, grid i računarstvo visokih performansi, te dijeljenje mrežne infrastrukture. Projektovan je i realizovan sistem za nadzor distribuirane heterogene računarske infrastrukture te je testiran za vrijeme trajanja projekta na regionalnoj infrastrukturi. Posebno značajan izlaz istraživanja je novi MIB (eng. Management Information Base) dokument koji podržava podatke iz svih analiziranih izvora. Nakon identifikovanja problema degradacije performansi u dijeljenim infrastrukturama projektovan je i sistem za korisnički
