Cloud Computing: Rackspace‟s Definition

“Unlimited” processing and storage

Abstracted/pooled resources

Elastic: scale up or down

On demand, Self-service

Highly automated

Consumption-based billing

System Infra. (IaaS)1

App. Infra. (PaaS)2

Applications (SaaS)3

Computing resources that are provisioned and managed via

software and programmatically accessible by any user

Target: Developers, Sys Admins

• Server, Storage, Network

• OS, Virtualization, File system

Infrastructure

as a Service

(IaaS)

Target: Developers

• Development tools

• Database, Middleware

• Infrastructure software

FOR EVERYONE, NOT EVERYTHING

Cloud is for Everyone….Not Everything

• Workloads with highly variable traffic (ie.

marketing promos or product launches)

• Workloads that are temporary in nature

• Test and Pre-production systems

• Mature packaged offerings like Email and

Collaboration

• Software development

• Batch jobs requiring minimal security

• Blogs, Media Rich websites

• Storage and Backup solutions

• Workloads requiring high IOPS

• Large relational data bases

• Workloads requiring significant regulatory

compliance, accountability

• Legacy software not designed for cloud

• Workloads requiring detailed utilization

measurement for billing or capacity planning

• Workloads requiring a lot of hardware

Popular Hybrid Usage Models

17

• Scalable Web Apps– Dedicated Hosting with high performance custom servers supporting predictable load

– Burst to the Cloud for peak demand

– Scale Storage on demand

Test, Development & Production

– Develop, test and stage on scalable, fast-to-deploy Cloud Servers

– Promote directly to the Dedicated Hosting production environment

– Scale up massively for full scale load testing, pay only for the time you’re testing

SaaS or VAR

– Mix-and-match Dedicated and Cloud Hosting to best support your customers' individual

needs and usage patterns

– Connect Dedicated and Cloud to enable multi-customer central management of your

SaaS applicationAdditional Use Cases

OpenStack Community Snapshot

OpenStack Mission

“To produce the ubiquitous open

source cloud computing platform

that will meet the needs of public and

private cloud providers regardless of

size, by being simple to implement

and massively scalable.”

OpenStack Mission

Why is OpenStack important?

• Open eliminates vendor lock-in

• Working together, we all go faster

• Freedom to federate, or move between clouds

OpenStack Founding Principles

• Apache 2.0 license (OSI), no paid „enterprise‟ version

• Open design process, 2x year public Design Summits

• Publicly available source code repository

• All community processes documented and transparent

• Commitment to drive and adopt open standards

• Modular design for deployment flexibility via APIs
