This design needs to be aligned with the expected use of the cloud, and it needs to describe which data center components are going to be part of the cloud. This comprises i) all the infrastructure components such as networking, storage, authorization and virtualization back-ends, as well as the ii) planned dimension of the cloud (characteristics of the workload, numbers of users and so on) and the iii) provisioning workflow, i.e. how end users are going to be isolated and using the cloud. In order to get the most out of a OpenNebula Cloud, we recommend that you create a plan with the features, perfor- mance, scalability, and high availability characteristics you want in your deployment. This Chapter provides infor- mation to plan an OpenNebula cloud based on KVM or LXD or vCenter. With this information, you will be able to easily architect and dimension your deployment, as well as understand the technologies involved in the management of virtualized resources and their relationship. 1.1.1 How Should I Read This Chapter This is the first Chapter to read, as it introduces the necessary concepts to correctly define a cloud architecture. Within this Chapter, as a first step, a design of the cloud and its dimension should be drafted. For KVM and LXD clouds proceed to Open Cloud Architecture and for vCenter clouds read VMware Cloud Architecture. Then you could read the OpenNebula Provisioning Model to identify the model wanted to provision resources to end users. In a small installation with a few hosts, you can skip this provisioning model guide and use OpenNebula without giving much thought to infrastructure partitioning and provisioning. But for medium and large deployments you will probably want to provide some level of isolation and structure. Once the cloud architecture has been designed, the next step would be to learn how to install the OpenNebula front-end. 1.1.2 Hypervisor Compatibility Section Compatibility Open Cloud Architecture This Section applies to KVM and LXD. VMware Cloud Architecture This Section applies to vCenter. OpenNebula Provisioning Model This Section applies to both KVM and vCenter. 1 OpenNebula 5.10 Deployment guide, Release 5.10.5 1.2 Open Cloud Architecture Enterprise cloud computing is the next step in the evolution of data center (DC) virtualization. OpenNebula is a simple but feature-rich and flexible solution to build and manage enterprise clouds and virtualized DCs, that combines existing virtualization technologies with advanced features for multi-tenancy, automatic provision and elasticity. OpenNebula follows a bottom-up approach driven by sysadmins, devops and users real needs. 1.2.1 Architectural Overview OpenNebula assumes that your physical infrastructure adopts a classical cluster-like architecture with a front-end, and a set of hosts where Virtual Machines (VM) will be executed. There is at least one physical network joining all the hosts with the front-end. A cloud architecture is defined by three components: storage, networking and virtualization. Therefore, the basic components of an OpenNebula system are: • Front-end that executes the OpenNebula services. • Hypervisor-enabled hosts that provide the resources needed by the VMs. • Datastores that hold the base images of the VMs. • Physical networks used to support basic services such as interconnection of the storage servers and OpenNebula control operations, and VLANs for the VMs. OpenNebula presents a highly modular architecture that offers broad support for commodity and enterprise-grade hy- pervisors, monitoring, storage, networking and user management services. This Section briefly describes the different choices that you can make for the management of the different subsystems. If your specific services are not supported we recommend checking the drivers available in the Add-on Catalog. We also provide information and support about how to develop new drivers. 1.2.2 Dimensioning the Cloud The dimension of a cloud infrastructure can be directly inferred from the expected workload in terms of VMs that the cloud infrastructure must sustain. This workload is also tricky to estimate, but this is a crucial exercise to build an 1.2. Open Cloud Architecture 2 OpenNebula 5.10 Deployment guide, Release 5.10.5 efficient cloud. The main aspects to take into account at the time of dimensioning the OpenNebula cloud follow. OpenNebula front-end The minimum recommended specs are for the OpenNebula front-end are: Resource Minimum Recommended configuration Memory 8 GB CPU 1 CPU (4 cores) Disk Size 100 GB Network 2 NICs Please take into account that these recommendations are meant as a guidance and may be relaxed or increased depend- ing on the size and workload of your cloud. The maximum number of servers (virtualization hosts) that can be managed by a single OpenNebula instance strongly depends on the performance and scalability of the underlying platform infrastructure, mainly the storage subsystem. The general recommendation is no more than

Agata 98166, Messina, Italia [email protected]; [email protected]; [email protected]; [email protected] Abstract-Nowadays, cloud computing offers more and more business opportunities, and thanks to the concept of virtualization, different types of cost-effective Cloud-based services have been rising. Virtualization of computing, storage, and networking resources, and their interconnection is at the heart of cloud computing, hence enabling new E-Business scenarios. In such a context, APIs for enabling Cloud-based services are strongly required, nevertheless, methods, mechanisms and tools for exploiting virtualized resources and their utilization for developing anything as a service (*aaS) are still ad-hoc and/or proprietary in nature. In this paper, we discuss how to use an adaptive standard protocol, i.e., XRI, for enabling cloud service providers to arrange their own Cloud- based services, building them on top of the IaaS provided by other service providers. Keywords- Cloud Computing; Cloud Management; Federation; Service Composition; E-Business I. INTRODUCTION Today, cloud computing represents a tempting business opportunity for ICT operators of increasing their revenues [1,2]. The cloud ecosystem begins to be clearer and the role played by cloud service providers appears more defined than the past. Moreover, the number of new public, private, and hybrid clouds rising all over the world is continually growing [3].

    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).
