Cloud Computing Explained

What is Clouding Computing?

• A style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.

Cloud Computing Definition

(NIST)

Cloud computing is a model for enabling ubiquitous,

convenient, on-demand network access to a shared pool

of configurable computing resources (e.g., networks,

servers, storage, applications, and services) that can be

rapidly provisioned and released with minimal

management effort or service provider interaction.

This cloud model promotes availability and is composed

of

five essential characteristic

three service models

four deployment models.

5 Characteristics of Cloud System

On-demand self-service

Broad network access

Resource pooling

Rapid elasticity

Measured Service

Three Cloud Service Models

Cloud Deployment Model

• Internal cloud used by an organization

Private Cloud

• Internal Cloud Shared by multiple organizations

Community Cloud

• Providers Cloud shared by many users

Public Cloud

• Cloud that composed of two or more cloud

Hybrid Cloud

Why Cloud Computing?

The illusion of infinite computing resources available on demand, thereby eliminating the need for Cloud Computing users to plan far ahead for provisioning.

The elimination of an up-front commitment by Cloud users, thereby allowing companies to start small and increase hardware resources only when there is an increase in their needs.

The ability to pay for use of computing resources on a short-term basis as needed (e.g., processors by the hour and storage by the day) and release them as needed, thereby rewarding conservation by letting machines and storage go when they are no longer useful.

Power Grid

Power Grid Inspiration for Computing?: Deliver

ICT services as “computing utilities” to users

(Promised) Benefits of (Public) Clouds

No upfront infrastructure investment

No procuring hardware, setup, hosting, power, etc..

On demand access

Lease what you need and when you need..

Efficient Resource Allocation

Globally shared infrastructure, can always be kept busy by serving users from different time zones/regions...

Nice Pricing

Based on Usage, QoS, Supply and Demand, Loyalty, …

Application Acceleration

Parallelism for large-scale data analysis, what-if scenarios studies…

Highly Availability, Scalable, and Energy Efficient

Supports Creation of 3rd Party Services & Seamless offering

Builds on infrastructure and follows similar Business model as Cloud

Google App Engine

Google App Engine is a platform for developing and hosting web applications in Google-managed data centers

first released as a beta version in April 2008.

Google App virtualizes applications across multiple servers and data centers.

Google App Engine is free up to a certain level of used resources. Fees are charged for additional storage, bandwidth, or CPU cycles required by the application.[

TREND AND DIRECTION

Trends and Direction

Cloud computing is at an early stage

Public cloud available from many vendors such as Amazon EC2, Google App

Private and Hybrid cloud is a coming trends

Cloud computing is still

Need standard for things such as programming API, Security mechanism

One of the technology with high potential that everyone should follow the development.
