Cloud Computing

Definition:Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources:

• NETWORKS • SERVERS• STORAGE• APPLICATIONS• SERVICES

that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Cloud Computing

Product your own electricity vs. Paid per consume

From Water-Wheel to Utility Power

Cloud Computing

Cloud Service Characteristics

• On-demand self servicePossibility for end users to sign up an receive the service without delays

• Broad network accessService can be accessed via standards platforms

• Resource poolingResources are pooled across multiple customers

• Rapid elasticityCapacity can scale to cope with demand peaks

• Measured serviceBilling is metered and delivered as a utility service

Cloud Computing

I. Virtualization – The ability to increase computing efficiency

II. Democratization of computing – Bringing enterprise scale infrastructure to small and medium businesses

III. Scalability and fast provisioning – Bringing web scale IT at a rapid pace

IV. Commoditization of infrastructure – Enabling IT to focus on the strategic aspects of its role

Enablers:

Cloud Computing: Need all Enablers working together

Cloud Computing

I. Virtualization: The ability to increase computing efficiency

Enabling pseudo-servers to be run on one physical device.

The division of a single physical server into Multiple “virtual”

servers containing multiple sets of segregated data.

Cloud Computer Backbone

Cloud Computing

I. Virtualization: The ability to increase computing efficiency

Increase• Flexibility• Resource allocation• Efficiency gains in terms of processing power

Decrease• Electric power• Space• Cooling

Cloud Computing

II. Democratization of computing: Bringing enterprise scale infrastructure to small and

medium businesses

Easy business development, enabling saving in:• Hardware• Software Licenses

Ability for small and medium companies to rapidly scale infrastructure to levels only achieved by largest organizations.

Cloud Computing

III. Scalability and Fast Provisioning:

Cloud Computing enables organizations to:

1. Maintain infrastructure at required levels at all times

2. Cost saving originated in the aggregated cost per unit. Paying only for what is required when is required

Despite the cost per Unit from an Utility Service Provider, can be higher than an owned resource.

For Organizations where workload has processing picks.

There are two situations:

1. Over provision of servers: Creating unused capacity and higher cost per process.

2. Under provision of servers: Creating impacts in terms of quality of service levels.

III. Scalability and Fast Provisioning:

Cloud Computing

Cloud Computing

IV. Commoditization of InfrastructureEnabling IT to focus on the strategic aspects of its role

Cloud Computing offers:

• The ability for IT departments to apply resources as, and where, they are needed.

• To the organizations to focus in their core business.

Business Agility is the main reason to migrate to Cloud Computing (over Cost savings)

Cloud Computing

Categories within Cloud Computing• SaaS: Software as a Service

Applications are designed for end-users, delivered over the web.

• PaaS: Platform as a ServiceSet of tools and services designed to make coding and deploying those applications quick and efficient.

• IaaS: Infrastructure as a ServiceHardware or Software that powers it all, includes: Servers, storage, networks and operating systems.
