Openstack
- 2. • OpenStack is a free and open-source cloud-computing software platform. • Users primarily deploy it as an infrastructure-as-a-service(IaaS). The technology consists of a group of interrelated projects • It control pools of processing, storage, and networking resources throughout a data center • Data center - which users manage through a web-based dashboard, through command-line tools, or through a Restful API. • OpenStack.org released it under the terms of the Apache License.
- 3. OPENSTACK as a joint projects • Started in 2010. • Joint project with NASA and Rackspace Hosting. • More efforts was provided to deliver technology for enterprise cloud. • The OpenStack effort will hit the market as a new challenger to Amazon's cloud and S3 services. • The NASA Nebula project was built with the Ubuntu Linux distribution, to partner with Rackspace in the OpenStack effort has to do with the flexibility of storage choices, since NASA's large images and datasets make its storage requirements immense.
- 4. HISTORY • In July 2010, Rackspace Hosting and NASA jointly launched an open- source cloud-software initiative known as OpenStack. • The OpenStack project intended to help organizations offer cloud- computing services running on standard hardware. • The community's first official release, code-named Austin, appeared four months later, with plans to release regular updates of the software every few months. • The early code came from NASA's Nebula platform as well as from Rackspace's Cloud Files platform.
- 5. • In 2011, developers of the Ubuntu Linux distribution adopted OpenStack with an unsupported technology preview of the OpenStack "Bexar" release for Ubuntu 11.04 "Natty Narwhal". • Ubuntu's sponsor Canonical then introduced full support for OpenStack clouds, starting with OpenStack's Cactus release.
- 6. • OpenStack became available in Debian Sid from the Openstack "Cactus" release in 2011, and the first release of Debian including OpenStack was Debian 7.0 (code name "Wheezy"), including OpenStack 2012.1 (code name: "Essex").
- 7. • In October 2011, SUSE announced the public preview of the industry's first fully configured OpenStack powered appliance based on the "Diablo" OpenStack release.
- 8. • In 2012, Red Hat announced a preview of their OpenStack distribution, beginning with the "Essex" release. After another preview release, Red Hat introduced commercial support for OpenStack with the "Grizzly" release, in July 2013.
- 9. HOW OPENSTACK USED IN CLOUD ENVIRONMENT • The cloud is all about providing computing for end users in a remote environment, where the actual software runs as a service on reliable and scalable servers rather than on each end users computer. Cloud computing can refer to a lot of different things, but typically the industry talks about running different items "as a service"—software, platforms, and infrastructure. • OpenStack falls into the latter category and is considered Infrastructure as a Service (IaaS). Providing infrastructure means that OpenStack makes it easy for users to quickly add new instance, upon which other cloud components can run.
- 10. • Typically, the infrastructure then runs a "platform" upon which a developer can create software applications which are delivered to the end users. • We report on design, implementation and evaluation of a resource management system that builds upon OpenStack, an open-source cloud platform for private and public clouds.

- 12. COMPUTE (NOVA) • OpenStack Compute (Nova) is a cloud computing fabric controller, which is the main part of an IaaS system. • It is designed to manage and automate pools of computer resources and can work with widely available virtualization technologies, as well as bare metal and high-performance computing (HPC) configurations. • KVM, VMware, and Xen are available choices for hypervisor technology (virtual machine monitor), together with Hyper-V and Linux container technology such as LXC.
- 13. • It is written in Python and uses many external libraries such as Eventlet (for concurrent programming), Kombu (for AMQP communication), and SQLAlchemy (for database access) • Compute’s architecture is designed to scale horizontally on standard hardware with no proprietary hardware or software requirements and provide the ability to integrate with legacy systems and third- party technologies.
- 14. OBJECT STORAGE (SWIFT) • OpenStack Object Storage (Swift) is a scalable redundant storage system. • Objects and files are written to multiple disk drives spread throughout servers in the data center, with the OpenStack software responsible for ensuring data replication and integrity across the cluster. • Storage clusters scale horizontally simply by adding new servers. Should a server or hard drive fail, OpenStack replicates its content from other active nodes to new locations in the cluster.
- 15. DASHBOARD (HORIZON) • Provides administrators and users a graphical interface to access, provision, and automate cloud-based resources. • The design accommodates third party products and services, such as billing, monitoring, and additional management tools. • The dashboard is also brandable for service providers and other commercial vendors who want to make use of it. The dashboard is one of several ways users can interact with OpenStack resources. • Developers can automate access or build tools to manage resources using the native OpenStack API or the EC2 compatibility API.
- 16. IDENTITY SERVICE (KEYSTONE) • Provides a central directory of users mapped to the OpenStack services they can access. • It acts as a common authentication system across the cloud operating system and can integrate with existing backend directory services like LDAP. • It supports multiple forms of authentication including standard username and password credentials, token-based systems and AWS- style logins. • Additionally, the catalog provides a queryable list of all of the services deployed in an OpenStack cloud in a single registry. Users and third- party tools can programmatically determine which resources they can access.
- 17. BARE METAL PROVISIONING (IRONIC) • Ironic is an incubated OpenStack project that aims to provision bare metal machines instead of virtual machines. • It was initially forked from the Nova Baremetal driver and has evolved into a separate program. It is best thought of as a bare-metal hypervisor API and a set of plugins that interact with the bare-metal hypervisors. • By default, it will use PXE and IPMI in concert to provision and turn on and off machines, but Ironic supports and can be extended with vendor-specific plugins to implement additional functionality.
- 18. ELASTIC MAP REDUCE (SAHARA) • Sahara aims to provide users with simple means to provision Hadoop clusters by specifying several parameters like Hadoop version, cluster topology, nodes hardware details and a few more. • After a user fills all the parameters, Sahara deploys the cluster in a few minutes. Sahara also provides means to scale an already- provisioned cluster by adding and removing worker nodes on demand.
