What do these things have in common?

Who am I

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

The web scale

“... 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

The real paradigm shift

The details

The stack

Infrastructure As A Service

Platform As A Service

Software As A Service

The trade-offs

Enter OpenStack

Virtualized data centers, servers come first

Better resource utilization for each server

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

2. Cloud Data Center 3. Cloud Federation1. Virtualization

Automation & Efficiency

HYPERVISORS PROVIDE ABSTRACTION BETWEEN APPS AND HARDWARE (SERVERS)

Next come storage, networks

Compute Pool Network Pool Storage Pool

ABSTRACTION BETWEEN APPS AND HARDWARE



Virtualized Servers Virtualized Networks Virtualized Storage

Resource pools for apps starting to form...

Flexibility, Efficiency are key drivers

Questions arise when virtual environments grow

+

How do you empower employees to self-service?

USERS ADMINS

How do you make your apps cloud aware?

Where should you provision new VMs?

How do you keep track of it all?

“VM SPRAWL” CAN MAKE THINGS UNMANAGEABLE VERY QUICKLY

APPS



VM sprawl can make things unmanageable quickly

USERS ADMINSAPPS



A Cloud Management Layer Is Missing



USERS ADMINS

A management layer to add automation and control

APPS

Creates Pools of Resources Automates The Network

CLOUD OPERATING SYSTEM

Connects to apps via APIs

Self-service Portals for users

What's next

Enterprise Private Clouds run cloud operations systems…

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

The core of OpenStack

OpenStack Capabilities Project Codename

Virtual Machines: provision & manage large pools of on-demand 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

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
