70+ companies, 100s of developersOpenStack Community

Reward

Asynchronous eventually consistent communication: RabbitMQ message queue 

RESTful API

Horizontally and massively scalable: Use local storage to run VM

Hypervisor agnostic: support for XenServer, KVM, ESX, Hyper-

V, etc.Hardware agnostic: commodity hardware

OpenStack Compute

Data distributed evenly throughout system

Hardware agnostic: commodity hardware, RAID not required

OpenStack Object Storage

No centraldatabase

Scalable to multiple petabytes, billions of objects

Account/Container/Object structure: ideal for virtual disk images, static data, CDN, not a file system, no nesting

Replication: N copies of accounts, containers, objects 

RESTful API

• Image registry and delivery service• RESTful API• Store virtual disk images in various backend storage

systems• OpenStack Object Storage, Amazon S3, file system, read-only HTTP store

• Store image metadata in a registry

OpenStack Image Service

• Native Flat and VLAN based network isolation• Network Connectivity as a Service to provide more flexibility

• API for Layer 2 operation• Multiple vendor plugins

OpenStack Networking

Flat Flat (DHCP) VLAN

Network Connectivity as a Service

Network Container Service

IPAM Service

• Dashboard• Volume as a service• Load balancing as a service• Database as a service• …

Looking Closer at an IaaS Cloud

Private Clouds Public Clouds

Built for traditional enterprise apps & client-server compute• Scale-up (pool-based)• Enterprise hardware components• IT Mgmt-centric [1:100’s]• Proprietary vendor stack

Designed around big data, new workloads & next-gen apps• Scale-out (horizontal resourcing)• Commodity hardware components• Autonomic [1:1,000’s]• Open, value-added stack

Think: Server Virtualization ++ Think: Amazon Web Services

Reality

The Cloud Pioneers All Use Next Generation Architectures

Worlds largest public cloud environment

Delivering video on demand via the cloud

Uses the cloud to sell more pigs

Transformed their hosting business with the cloud

Uses the cloud to disrupt the way we communicate

Built one of the fastest growing and most innovative companies on the planet on the cloud

•Secure, multi-tenant platform– Designed to build and orchestrate clouds– Hypervisor agnostic– Massively scalable and efficient– Self service portal– Open source, open standards– Deploys in public or private cloud environments

•Deliver cloud services 50 times faster at 1/5th the cost •Committed to OpenStack support

60+ Large Scale Clouds

In Deployment

Cloud.com powers the world’s most innovative clouds

Strong Commitment to OpenStack Prevents Lock-In
