Cloud Computing Layers

SaaS - User Cloud a.k.a Software as a ServiceEg: Google Docs

PaaS - Development Cloud a.k.a Platform as a ServiceEg: Google AppEngine, Microsoft Azure

IaaS - Systems Cloud a.k.a Infrastructure as a ServiceEg: EC2, CloudStack

Deployment Models

Public CloudsA public cloud is one based on the standard cloud computing model, in which a

service provider makes resources, available to the general public

Private CloudsPrivate cloud is infrastructure operated solely for a single organization, whether

managed internally or by a third-party and hosted internally or externally

Hybrid Clouds

Hybrid cloud is a composition of two or more clouds that are bound together though

unique, offering the benefits of multiple deployment models

What is Open Source?

OSI says...

Open source is a development method for software that harnessesthe power of distributed peer review and transparency of process.The promise of open source is better quality, higher reliability, moreflexibility, lower cost, and an end to end predatory vendor lock-in.

Main Elements of OSI definition

The Software could be redistributed without restriction

The Source code must be available

License can require improved versions to carry attribution anddifferent names

State of OSS Adoption in the Cloud

SAAS - dominated by proprietary vendors

SAAS may run on OSS (Linux, MySQL etc.)

PAAS - A little more (AppScale etc.)

IAAS (Public Clouds)

Lead by Closed Source EucalyptusClosely followed by the Open Source RackSpace OpenStack

IAAS (on Premise Clouds)

Lead by Open Source Systems all the wayEucalyptus, OpenNebula etc.

Importance of Cloud Management

Cloud computing is not a magical solution

Cloud requires self-service capability

therefore should manage metering, monitoring, workloadmanagement etc.

Performance should be measured and monitored

Even more important when companies rely on more than one cloudservice provider
