1. 1 TCS Confidential

2. 2 Objective: In this session we will be able to learn  What is Openstack?  History  Capabilities  Openstack as IaaS  Advantages and Disadvantages  Future of Openstack

3. 3 TCS Confidential As described by the Openstack Foundation: “Open source software for building public and private clouds”

4. 4 TCS Confidential  In July 2010, Rackspace Hosting and NASA jointly launched an openstack-source cloud- software initiative known as Openstack.  More than 200 companies have joined the project including Cisco, Ericsson, Dell, Red Hat, AT &T, Oracle, Yahoo, VMware etc.  The most recent Openstack Summit, in May 2014 in Atlanta, drew a 4,500 attendees, a 50% increase from the Hong Kong Summit six months earlier.

7. 7  VMs on demand  provisioning  snapshotting  Volumes  Networks  Object storage VM images and arbitrary files  Multi-tenancy  Quotas for different tenants  Users can be associated with multiple tenants

8. 8 TCS Confidential  It can be upgraded easily.  It provides Infrastructure as a Service(IaaS) for managing large groups of public and private clouds.  Available any time at any computer or location through a web browser.  Simple to integrate ( Any Organization can offer cloud computing services using their standard hardware E.g. Amazon).  Can limit storage access to users.  Protects drive failures by preventing and controlling data corruption.  Low costs per megabyte of storage.

9. 9 TCS Confidential  Servers are not always reliable and issues could dissatisfy customers.  Technical support is offered only through email and chat.  Uploads are time consuming.  Software still being produced.  Software is constantly changing and the user must keep up with up to date changes.

10. 10 TCS Confidential  The main barriers of adoption for this software are the disadvantages of the product and deciding whether the technology suits the system of the company.  A users must also consider the products competitors. E.g. Eucalyptus, Apache Cloud stack and Flexiant are Openstack competitors.  Lastly Openstack is still being developed and investigating in under developed software could be a risk.

11. 11 TCS Confidential  Openstack is a free and open-source cloud computing software platform.  The Openstack community collaborates around a six-month, time-based release cycle with frequent development milestones.  Provides platform for launching VMs either by images or by snapshots.

12. 12 TCS Confidential  What is the main purpose of using Openstack?  What is the current stable version of Openstack?  What functionalities does Openstack provides for launching VM’s?  Under what cloud flavor does Openstack comes?  List some of the product competitors for Openstack?

13. 13 TCS Confidential Objective: In this session we will be able to learn  Architecture of beginning and latest versions of Openstack  Development trends  Components of Openstack  How Openstack projects are related to each other?  Deployment topology of the Openstack

14. 14 TCS Confidential

15. 15 TCS Confidential

16. 16 TCS Confidential  Decoupling of features (e.g. Nova-volume became cinder, Nova-Networking became Neutron)  API-s to communicate  Common generic API/Infrastructure (Oslo)  Back ends and drivers (everything’s pluggable)

17. 17 TCS Confidential  Compute (Nova).  Object Storage (Swift).  Block Storage (Cinder).  Networking (Neutron).  Dashboard (Horizon).  Identity Service (Keystone).  Image Service (Glance).  Telemetry (Ceilometer).  Orchestration (Heat).  Database (Trove).  Bare Metal Provisioning (Ironic).  Multiple Tenant Cloud Messaging (Zaqar).  Elastic Map Reduce (Sahara).

18. 18 TCS Confidential

19. 19 TCS Confidential  Simple self-service UI for end-users.  Growing list of cloud-administrator functions: –Define Tenant/Project, User, Quota, Compute, Storage, Network and other resources. –Limited infrastructure management.  Stateless client of OpenStack API's.

20. 20 TCS Confidential  Common Authentication/Authorization Framework  Manages users, tenants and roles  Supports pluggable backends (SQL, PAM, LDAP, etc.)  Also provides Catalog Registry for OpenStack Services

21. 21 TCS Confidential  Schedules, builds, runs and manages compute instances on underlying hypervisor.  Exposes native Openstack API and Amazon EC2 compatible API.  Configures guest instances via Metadata injection or Config. file

22. 22 TCS Confidential  Stores and retrieves Disk Images (VM templates).  Supports RAW, QCOW, VMDK, VHD, ISO, OVF and AMI/AKI images.  Supports a variety of backend storage options, including local file system, Swift and Amazon S3.

23. 23 TCS Confidential  Provides Block Storage for VM's (Persistent disks).  Similar to Amazon EBS service.  Plugin architecture for vendor extensions (e.g., Gluster driver for Red Hat Storage).

24. 24 TCS Confidential  Modeled after Amazon S3 service.  Provides simple service for storing and retrieving arbitrary data.  Native API and S3 compatible API

25. 25 TCS Confidential  Framework for network connectivity.  Interconnect tenant compute instances via various overlay network types.  L3-agent for external connectivity, DHCP-agent for IP address allocation.  Load Balancer-as-a-Service, Firewall-as-a-Service and VPN-as-a-Service.

34. 34 TCS Confidential  Cactus – Functionalities are handled by Nova itself  Horizon is the common UI that provide web front to other Openstack services  All services authenticate with Keystone  Every service is associated to its own database which stores its state  Similarly every service has its own Message Queue where its state is stored as message in the message queue.  Control cluster contains all the services  Compute node provides resources for launching VMs  Storage node provides resources for storing and managing data  Compute and storage nodes are controlled by the controller

35. 35 TCS Confidential  What is the primary role of Nova?  What are the different types of storage available?  What are the features that are decoupled in Ice House?  Quantum is now called as ----------------.  What are the services available in the control cluster?  Why Compute Node requires Heavy CPU and RAM?
