1 Debasis Roy Choudhuri Joydipto Banerjee Cloud Computing Session 4 : Open Source Cloud Computing

2 Open source and cloud computing the best of both worlds Ever felt like creating your own little private cloud on your desktop or laptop? Or, just wanted to explore what the cloud software really does? If you think there s too much cost involved for these initiatives, think again, because open source is there to the rescue! + + = Cloud Open Open Source Cost Computing Standards Flexibility 2

3 Open Source Offerings various possibilities An example of Open Source Cloud environment on Intel x86 platform with Linux as the base. Following facilities can be on offer to start with: Infrastructure as a Service (IaaS) Vanilla Linux images (e.g. Red Hat, SUSE, Ubuntu, Debian) with basic utilities Platform as a Service (PaaS) Programming Environment: Java and C/C++ compilers, Perl, Python etc. Database: MySQL Web: Apache Portal: JBoss Software as a Service (SaaS) ERP: OpenERP, OFBiz 3

4 What would you need to build an open source cloud? Hardware Intel x86 (VT enabled). In most cases, you would need two physical machines: One (usually called front end) to run the cloud software The other (usually referred to as node) for provisioning the virtual images meant for users. However, some environments will even allow you to run both front end and node on a single physical machine, if you want to have a limited capability setup. Operating System Ubuntu, Red Hat Enterprise Linux (RHEL), CentOS, SUSE Linux Enterprise Server (SLES), opensuse, Debian and Fedora. Hypervisors A comparative study of Hypervisors under is shown in the next slide. Virtual networking - To optimize network communication among virtual machines (VMs), you need a virtual switch. The most commonly used is known as Open vswitch. It is the default switch in the Xen Cloud Platform and also supports Xen, XenServer, and KVM. Recently it is also integrated into other open source cloud platforms like Open Nebula and Open QRM. Infrastructure management ovirt, VirtManager The ovirt package, developed by Red Hat, is a Web-based management console. VirtManager, also developed by Red Hat, is GTK based and presents a much more graphically rich display (for live performance and resource utilization). 4

6 Open source software to build private and public cloud Eucalyptus One of the most popular open source packages for building cloud computing infrastructures. Interface is compatible with Amazon EC2. Includes Walrus - a cloud storage application compatible with Amazon Simple Storage Service (Amazon S3) OS Ubuntu, RHEL, CentOS, SLES, opensuse, Debian and Fedora. Hypervisor - VMware, Xen and KVM OpenNebula Supports private cloud construction and the idea of hybrid clouds. OS - OpenNebula is included in Debian wheezy, Ubuntu Natty Hypervisor - Xen, KVM and VMware 6

7 Open source software to build private and public cloud (contd.) Xen Cloud Platform (XCP) XCP 1.0 is the first full release of the Xen Cloud Platform Includes Xen hypervisor Supported guest operating systems - RedHat, Debian, CentOS, SUSE Xen.org/products/cloudxen.html OpenQRM Focuses on automatic, rapid deployment, monitoring and high-availability Supported OS Debian, Ubuntu, CentOS, SuSE, Fedora Hypervisor - VMware, Xen, KVM and Linux-VServer Nimbus Compatible with Amazon APIs Supported OS RedHat, Debian, Ubuntu Hypervisor Xen and KVM 7

8 Basic components of OpenNebula system are: - Front-end - Hosts - Image repository - Networking ONED: Open Nebula Daemon: It controls the VM life cycle Drivers: Modular Components - to control the node services Types: Storage, Monitoring, Virtualization & Network Nodes: The VMs get created here. Nodes must have an hypervisor installed Front End: Central Server - manages nodes, templates, VMs, users FRONT-END Drivers ONED Images: Virtual Image Repositories. Contains various software stacks and VM templates Images SSH Images New VMs provisioned Hypervisor 8 NODE Sample Model Image Stacks: Database MySql on Linux Java/ C++ on Linux

9 The shortcut! Ubuntu Server Edition to the rescue Ubuntu Enterprise Cloud (UEC) provides virtualization capability, applications and flexibility to help deploy a cloud within an organization. It consists of the open core Eucalyptus, libvirt, KVM or Xen virtualization technology Build your own Cloud in 1 hour Complete installation guide 9
