  • Openstack Designate
    OpenStack Designate Stephan Lagerholm Graham Hayes What is OpenStack? OpenStack is a free open standard cloud computing platform, mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through RESTful web services. OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2012, it was managed by the OpenStack Foundation (Source: Wikipedia) 2 Designate • Designate started as a project to maintain DNS infrastructure for OpenStack Users. It was an ecosystem project that was in production at both HP’s and Rackspace’s clouds. During 2015, Designate was moved into OpenStack Foundation and in 2017 it became a registered trademark. • Designate is providing API, CLI and a Graphical User interface so that OpenStack Users can setup and make changes to DNS data. The zones are thereafter exposed to secondary DNS servers via Zone Transfers. • Officially Bind 9.X and PowerDNS 4.X is supported although other DNS servers are known to work too. Most resource Record Types such as A, AAAA, PTR, CNAME, NS, MX, etc are supported 3 Producer Producer Backend Producer Producer Producer Worker Customer Facing API Central DNS Servers Standard XFR Secured by TSIG Nova / DB Mini

  • 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).

Gothenburg, Sweden 2016 iv Scaling OpenStack Clouds Using Peer-to-peerTechnologies XIN HAN Department of Computer Science and Engineering Chalmers University of Technology and University of Gothenburg Abstract OpenStack is an open-source software platform for cloud computing, mostly de- ployed as an infrastructure-as-a-service (IaaS) and has a user base in industry and academia to date. Despite its popularity, OpenStack still has drawbacks in terms of scalability of number of compute nodes (metal machines) in a single cloud instance. More precisely, a single standard OpenStack cloud instance does not scale well and fails to handle user request once its number of compute nodes reaches a particular amount.
