This document provides an overview of OpenStack and Reddwarf architectures. OpenStack is an open source cloud computing platform consisting of services like identity (Keystone), compute (Nova), image (Glance), networking (Quantum), and block storage (Cinder). Reddwarf builds on OpenStack to provide a platform as a service for database instances using a REST API, task manager, and guest agent to manage MySQL instances. The presentation also covers developer vs deployer roles and links to project resources.

2. Agenda
‣ Overview
‣ OpenStack Architecture
‣ Reddwarf Architecture
‣ Developer vs Deployer
‣ Demo?
‣ Questions

3. Overview

4. OpenStack Founding Principles
‣ Apache 2.0 license (OSI), open development process
‣ Open design process, 2x year public Design Summits
‣ Publically available open source code repository
‣ Open community processes documented and
transparent
‣ Commitment to drive and adopt open standards
‣ Modular design for deployment flexibility via APIs

5. OpenStack Community
‣ User groups across the world
‣ Events
‣ Design Summit, Conference, and Meetups
‣ Contribute
‣ Documentation, Design, or Code
‣ Over 180 Companies

6. OpenStack Contributions
‣ Launchpad.net (Bugs/Blueprints)
‣ Code reviews (gerrit)
‣ Unit Tests
‣ Integration Tests
‣ Jenkins jobs with gates

7. Benefits of a Common Platform
‣ Common API contract for public/private cloud
‣ Easy to migrate to public when needed
‣ No vendor lock in with a single provider
‣ Run on commodity hardware

8. OpenStack Platform
‣ Python
‣ Did I mention open source?
‣ github.com/openstack

9. OpenStack Architecture

12. Keystone Identity Service
‣ Provides Identity, Token, Catalog, and Policy Services
‣ Authentication / Authorization
‣ Validation
‣ User management
‣ Project / Tenant management
‣ Service management

14. Glance Service
‣ VM Image Service for nova-compute
‣ Manage and deploy images
‣ Backend storage of images can be anything
‣ File based
‣ Swift
‣ S3
‣ Multiple Image Formats
‣ AMI / raw / iso / qcow / etc.

16. Nova APIs
‣ Rest based
‣ json/xml
‣ OpenStack Compute API
‣ Management API
‣ EC2 API
‣ Dashboard (Horizon)

19. Message Bus
‣ Backbone of system
‣ Message routing between
services
‣ Generic API to send messages
‣ Multiple drivers supported
‣ RabbitMQ
‣ ZeroMQ
‣ Qpid

21. Nova Database
‣ MySQL Server
‣ Stores all OS system data
‣ Instance info
‣ Network info
‣ Node info
‣ Python library SQL-Alchemy
ORM
‣ SQLite for unit testing
‣ Other relational databases

23. Nova-Scheduler Service
‣ Determines the placement of new resources requested via the API
‣ Modular architecture to allow for optimization
‣ Base Schedulers include
‣ Round Robin
‣ Filter Scheduler
‣ Spread First
‣ Fill First
‣ Chance (random)

25. Nova-Compute Service
‣ KVM
‣ QEMU
‣ Xen/Xen Server
‣ VMWare ESX/ESXi
‣ LXC
‣ OpenVZ
‣ HyperV

27. Nova-Network Service (Quantum)
‣ Provides network connectivity as a service
‣ Programmable networking
‣ Open vSwitch
‣ Nicira Network Virtualization Platform (NVP)
‣ Linux Bridge
‣ Ryu OpenFlow Controller
‣ On Demand creation of rich L2 + L3 topologies
‣ Quantum is the core project that came from this service

29. Nova-Volume Service (Cinder)
‣ Provide a Block Storage Service
‣ Create / Delete / Connect volumes to running
instances via iSCSI
‣ Drivers available
‣ LVM / iSCSI
‣ Multiple SAN drivers
‣ Ceph
‣ Cinder is newly formed core project

30. Platform as a Service
Reddwarf Architecture

31. Reddwarf Architecture

32. Reddwarf Architecture

33. Reddwarf API
‣ Rest Based
‣ Json/xml
‣ Create / Delete / Actions on Instance
‣ Extendable API
‣ Communication to the Guest Agent
‣ Keep API response fast (async)

34. Reddwarf Architecture

35. Reddwarf Task Manager
‣ Long running processes
‣ Create / Delete / Resize Instance
‣ Setting status when ACTIVE
‣ Synchronous process

36. Reddwarf Architecture

37. Guest Agent (Sneaky-Pete)
‣ Reference Agent (python)
‣ Listens on the Message Bus
‣ Updates MySQL Status to DB
‣ Sets up and secures the MySQL instance
‣ Controls and manages the MySQL instance
‣ Low memory footprint

38. Developer vs Deployer

39. Developers
‣ Devstack is documented shell script to build a
complete OpenStack development environment.
‣ http://devstack.org
‣ Setup a fresh Ubuntu Precise (12.04) or Fedora
16 installation (VM)
‣ VMware/Virtual Box/etc.
‣ Clone devstack
‣ Deploy your OpenStack Cloud
