Reasons for Using Open Source Clouds

Open Source Cloud Platfroms

Five Key Cloud Attributes:

1. Shared / pooled resources

2. Broad network access

3. On-demand self-service

4. Scalable and elastic

5. Metered by use

Shared / Pooled Resources:

• Resources are drawn from a common pool

• Common resources build economies of scale

• Common infrastructure runs at high efficiency

Broad Network Access:

• Open standards and APIs

• Almost always IP, HTTP, and REST

• Available from anywhere with an internet connection

On-Demand Self-Service:

• Completely automated

• Users abstracted from the implementation

• Near real-time delivery (seconds or minutes)

• Services accessed through a self-serve

web interface

Scalable and Elastic:

• Resources dynamically-allocated between users

• Additional resources dynamically-released when needed

• Fully automated

Metered by Use:

• Services are metered, like a utility

• Users pay only for services used

• Services can be cancelled at any time

Architecture Architecture OverviewOverview

Architectural Layers of Cloud Architectural Layers of Cloud ComputingComputing

In the cloud computing stack, there are three basic layers that together create cloud environment. They are:

1.Infrastructure as a Service(IaaS)2.Platform as a Service (PaaS)3.Software as a Service (SaaS)
