1 From iron to the cloud and beyond Presentation for SFSU Stefano Maffulli, OpenStack Community Manager

2 What do these things have in common?

7 Who am I

15 The lesson of Brunelleschi Be able to study how things work Study the source code Be able to modify and adapt what you learn Modify the code Be able to teach others Copy the code and share it with others

16 What is cloud computing

17 Web based applications Virtualization Cloud computing Services on demand IT on demand

18 Evolution of IT Mainframe Computing 1960 Enterprise Computing 1980 Cloud Computing 2000 Disruptions 2020

19 Evolution of computing models SLA Scaling 99.9 Vertical Horizontal Custom Hardware HA type Always on Enterprise Hardware Commodity Software Software Centralized Decentralized Distributed Consumption Centralized Shared Self-service Mainframe Computing 1960 Enterprise Computing 1980 Cloud Computing

Commodity Software Software Centralized Decentralized Distributed Consumption

20 The legacy enterprise computing

21 The web scale

22 The real paradigm shift... get into the [Google] mindset... robustness has to be designed into your software... assume that the hardware [is] unreliable and broken... at any point. -- Adrian Cockcroft, Netflix Chief Cloud Architect

23 The details

24 The stack Software As A Service Platform As A Service Infrastructure As A Service

25 The trade-offs

26 Enter OpenStack

Virtualized data centers, servers come first HYPERVISORS PROVIDE ABSTRACTION BETWEEN APPS AND HARDWARE (SERVERS) HOST 1 HOST 2 HOST 3 HOST 4, ETC.

27 Virtualized data centers, servers come first HYPERVISORS PROVIDE ABSTRACTION BETWEEN APPS AND HARDWARE (SERVERS) HOST 1 HOST 2 HOST 3 HOST 4, ETC. VMs Hypervisor: Turns 1 server into many virtual machines (instances or VMs) (VMWare ESX, Citrix XEN Server, KVM, Etc.) Hardware abstraction for each server 1. Virtualization Automation & Efficiency 2. Cloud Data Center Better resource utilization for each server 3. Cloud Federation

28 Next come storage, networks ABSTRACTION BETWEEN APPS AND HARDWARE Compute Pool Virtualized Servers Virtualized Networks Flexibility, Efficiency are key drivers 1. Virtualization Automation & Efficiency Storage Pool Network Pool 2. Cloud Data Center Virtualized Storage Resource pools for apps starting to form Cloud Federation

29 Questions arise when virtual environments grow VM SPRAWL CAN MAKE THINGS UNMANAGEABLE VERY QUICKLY USERS APPS How do you make your apps cloud aware? Where should you provision new VMs? ADMINS How do you empower employees to self-service? How do you keep track of it all? + 1. Virtualization Automation & Efficiency 2. Cloud Data Center 3. Cloud Federation

30 VM sprawl can make things unmanageable quickly USERS APPS ADMINS A Cloud Management Layer Is Missing + 1. Virtualization Automation & Efficiency 2. Cloud Data Center 3. Cloud Federation

31 A management layer to add automation and control APPS Connects to apps via APIs USERS ADMINS Self-service Portals for users CLOUD OPERATING SYSTEM Creates Pools of Resources 1. Virtualization Automation & Efficiency 2. Cloud Data Center Automates The Network 3. Cloud Federation

32 What's next Enterprise Private Clouds run cloud operations systems Public Clouds run cloud operating systems But you can t interoperate if public clouds are built on proprietary software 1. Server Virtualization Automation & Efficiency 2. Cloud Data Center 3. Cloud Federation

33 Imagine having a Common Platform across clouds Seamlessly transporting workloads 1. Virtualization Automation & Efficiency 2. Cloud Data Center 3. Cloud Federation

34 Connecting clouds to create global resource pools Common software platform making federation possible Texas Europe Private Cloud Run applications on a private cloud in your own data center. Automation & Efficiency Public Cloud California Private Cloud 1. Virtualization Washington Public Cloud Mirror content to a private cloud in a colo facility for disaster recovery 2. Cloud Data Center Cloudburst into multiple public clouds around the world when demand surges 3. Cloud Federation

35 Explosive community growth Developers Conference Attendees Latest release created by >200 Developers from 55 companies worldwide

36 Users of OpenStack

37 User stories We wanted our internal users to be able to create their own servers, virtual machines, storage, and networks. They d be able to provision themselves instantly with what they needed without having to wait for a system administrator. Mariano Guelar, infrastructure manager at MercadoLibre Our storage demands have been doubling every eighteen months. If your data are worth keeping, then they re worth keeping online and sharing. Stephen Meier, SDSC Storage Platforms Manager

38 The core of OpenStack OpenStack Capabilities Project Codename Virtual Machines: provision & manage large pools of ondemand computing resources Nova Virtual Block Storage Devices: Volumes on commodity storage gear, and drivers for more advanced systems like NetApp, Solidfire, and Nexenta Nova (now Cinder) Object Storage: petabytes of reliable storage on standard gear Swift Virtual Networks: VLAN or Flat Network, automation coming with Quantum project (Folsom Release fall 2012) Nova (now Quantum) Web Dashboard: self-service, role-based web interface Horizon Middleware: multi-tenant Identity Management that ties to existing stores (e.g. LDAP) and Image Service Glance, Keystone

39 The development process Open development Decisions are taken by technical leads, elected Design summit to define the roadmap Time based release cycle Every 6 months, in April and September Open source Apache Software License v2

40 How to get started DISTRIBUTIONS DEVSTACK TRYSTACK.ORG

41 Solution to the puzzle

42 Lahnam Napier, CEO Rackspace Rides a tractor for fun

43 Chris Kemp former NASA CIO CEO Nebula co-founder of OpenStack Gen. Pete Worden Nicknamed Darth Vader Hired Chris Kemp at NASA

45 The near future

47 2800 cores per rack 5 Watts per board 1.5W if idle
