De�nition of the Cloud

What is Cloud Computing?

�Cloud computing is a model for enabling convenient, on-demandnetwork access to a shared pool of con�gurable computingresources (e.g., networks, servers, Storage, applications, andservices) that can be rapidly provisioned and released with minimalmanagement e¤ort or service provider interaction� - (NIST, USA)

Main Characteristics





Private CloudPublic CloudHybrid CloudCommunity CloudOn-Promise VS. Cloud Computing

Private Cloud

Private CloudOperated for a single organizations

These services are managed and provided within theorganization.

Vendors: IBM, VMware, HP, Oracle (Data centers) etc.Infrastructure: Eucalyptus, 3Tera, IBM, VMware etc.






Public Cloud

Public CloudAvailable to general public or large industry group, owned byan organization selling Cloud services

These services are delivered to the client via the Internet froma third party service vendor.

Vendors: Amazon, Google, Microsoft, Salesforce etc.Infrastructure: Amazon, Rackspace, Gogrid, Joyent,Terramark etc.






Hybrid Cloud

Hybrid Cloud

Two or more Clouds that remain unique but are bound bytechnology that enables data and application portability

There is a combination of services provided from public andprivate Clouds.

Example: ERP in private Cloud and sales and Email onpublic Cloud






Community Cloud

Community Cloud

Shared by several organizations, supporting a speci�ccommunity

Community could shares infrastructures between severalorganizations from a speci�c community whether managedinternally or by a third-party and hosted internally orexternally.

Example: Mount Sinai Hospital in Toronto, Canada that willgive 14 area hospitals shared access to a fetal ultrasoundapplication and data storage for patient information






On-Promise VS. Cloud Computing

Separation of Responsibilities





Infrastructure as a Service - IaaSPlatform as a Service - PaaSSoftware as a Service - SaaS

Infrastructure as a Service - IaaS

IaaSCloud provider o¤ers capacity for rent, basically hosted DataCenter Servers

The service provider is responsible for the management of theunderlying Cloud infrastructure.

Pay-as- you-go model

Examples include: Amazon EC2, HP Cloud, Joyent,Rackspace, 3Tera, Google Compute Engine and WindowsAzure VM






Platform as a Service - PaaS

PaaSCloud providers deliver a computing Platform that enablesapplication developers to develop, run and host their solutions

The underlying platform that includes network, servers,operating systems, software for application development, etcis managed by the Cloud provider

Pay-as-you-go model

Examples include: Google AppsEngine, Windows Azurecompute, Force.com and SalesForce, VMware.






Software as a Service - SaaS

SaaSUsers are provided access to application software anddatabase on the Internet

Service providers manage the infrastructure and platform onwhich applications run

On-demand service =)Pay-as-you-go/ pay per useService Provides generally set subscription fee

Examples include: WindowsLive, Hotmail/Outlook, bing, msn,Messenger, Tellme, O¢ ce 365, Windows update.

Impact of the Cloud on the IT ecosystem

Changing role of telecommunication service providers (Netneutrality: Free vs. Google)

Challenges associated with existing data centers (Energy,Data center management, Storage management, Ensuringavailability)

Challenges associated with the traditional applicationdevelopment model : Microsoft on the Cloud (Phones GPSchips), O¢ ce 365

...and what about Open Source?
