  4. 4. What is OpenStack? OpenStack is a community of open source developers, participating organizations and users who are building and running the open source cloud operating system.Another definition … “OpenStack is a Cloud Operating System, that takes resources such as compute, storage, network, virtualization technologies and controls those resources at a data center level”
  5. 5. OpenStack, A Kernel of the Cloud OS Connects to apps via APIs Self-service Portals for users USERS ADMINS APPS CLOUD OPERATING SYSTEM Control & Automates Efficiently allocate resources Pools of ResourcesCompute Pool Storage Pool Network Pool Virtualized Virtualized Virtualized Servers Storage Networks

  15. 15. Core ProjectsCompute (code-named “Nova”) -open source software and standards for large-scale deployments of automatically provisioned virtual compute instances.Object Storage (code-named “Swift”) -open source software and standards for large-scale, redundant storage of static objectsImage Service (code-named “Glance”) -provides discovery, registration, and delivery services for virtual disk images.
  16. 16. OpenStack Incubated ProjectsOpenStack Identity (code-named Keystone) -The OpenStack Identity Service provides unified authentication across all OpenStack projects and integrates with existing authentication systemsOpenStack Dashboard -Dashboard enables administrators and users to access and provision cloud- based resources through a self-service portal.
  17. 17. Nova (OpenStack Compute) 1. REST-based API4. Hypervisor agnostic:support for Xen ,CitrixXenServer, Microsoft Hyper-V, 2. Horizontally and massivelyKVM, UML, LXC and ESX scalable 3. Hardware agnostic: supports a variety of standard hardware

  21. 21. Feature Benefit Programmatically allocate IPs and VLANs VLANs Manage Local Area Networks (LAN) Flexible networking models to suit needs of each - Flat, Flat DHCP, VLAN DHCP, IPv6 application and/or user group API with rate limiting and authentication Designed for automation and securityDistributed and asynchronous architecture Massively scalable and highly available system Live VM management (Instance) Increase productivity with lifecycle management Run, reboot, suspend, resize, terminate instancesCreate and manage Instance Types (Flavors) Build a menu of options for users to select from Define sizes of VMs for CPU, RAM & Disk Flavors make it easy to size VMs for workloads iSCSI storage volume management Enables data to be managed separate from VMs for fault- Create, delete, attach and transfer volumes tolerance and added flexibility Live migration of instances Minimize downtime with planned maintenance Floating IP addresses Keep IPs & DNS correct when managing VMs Flexibility to assign and control access to VM instances by Security Groups creating separation between resource pools Role Based Access Control (RBAC) Ensure security by user, role and project

  24. 24. Swift (OpenStack Object Storage)• Object Storage• Simple storage service (GET, PUT, DELETE, COPY)• Highly available, distributed, eventually consistent object/blob store• RESTful interface• No object size limit• 3+ replication factor in separate “zones”• Scales horizontally, No central index.• Stable and deployed in production
  25. 25. Swift main components Auth
  26. 26. Glance (OpenStack Image Service)• VM images and associated metadata• Discover, register and retrieve• Multiple disk formats : raw, VHD, vmdk, vdi, qcow2, aki, ari, ami• Multiple container formats: ovf, bare, aki, ari, ami
  27. 27. Glance Structure1. Store & retrieve VM images 2. REST-based API 3. Compatible with all common 4. Storage agnostic: image formatsStore images locally, or useOpenStack Object Storage, HTTP, or S3
  28. 28. Keystone (OpenStack Identity)• Unified tenants / accounts for all services
  29. 29. Dashboard (OpenStack Web UI)• Reference UI implementation• Django module to build web UIs
  30. 30. Quantum (OpenStack Network-aaS) Nova : virtual server Quantum : virtual networkBoth:- Expose a logical API for automated provisioning by cloud tenants.- Manage physical devices in the data center to implement the logical model.- Provide a “plugin” architecture to leverage support using different back-end technologies.
