Cloud Computing DefinitionCloud computing is Internet-

based computing, whereby sharedresources, software and information are provided to computers and other devices on-demand, like a public utility. “Wikipedia”

Oracle CEO Larry Ellison said: “Cloud Computing is using a computer that’s out there”.

Cloud Computing CharacteristicsUsers/Customers don’t own

the physical infrastructure.

The cloud offer all resources as a service.

You Only pay for the resources that you use.

Cloud Computing Key FeaturesCost

Claimed to be greatly reduced. The cloud service provider only charges you

on the amount of the computing resources that you use “Pay as you go”.

My point of view: Cost is greatly reduced for applications that need high computing power ONLY.

Eg, in Amazon’s EC2 a windows platform on small standard instance will cost around 0.12$/hour.

Cloud Computing Key Features cont.Virtualization

Packaging the application with everything it needs to run, including Database, Middleware and OS.

A virtualized application can be run anywhere on the cloud.

Cloud Computing Key Features cont.Multi-tenancy

In a multi-tanancy environment multiple customers share the same application, running on the same OS, on the same hardware.

Cloud Computing Key Features cont.Scalability

Increase or decrease the computing power on-demand.

Cloud Computing Key Features cont.Security

Data is stored in data centers. Data center generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices.

MaintenanceA third party maintains everything from

running the cloud to storing data, hardware maintenance and software upgrades.

Cloud Computing LayersCloud computing consists of five layers.

1. Client2. Application3. Platform4. Infrastructure5. Servers

Cloud Computing Layers Cont.The server layer consists of computer

hardware which are designed for the delivery of cloud services .

The cloud computing infrastructure consists of one or more server.

Cloud Computing Layers Cont.The infrastructure (also called IaaS) can offer

two types of services:

IaaS

SaaS HaaS

Hardware as a Service: Google

Apps

Software as a Service: Amazon

EC2

Amazon’s EC2Amazon Elastic Compute Cloud (Amazon EC2) is a web

service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.

Amazon provide a basic measure of an EC2 compute unit: One EC2 Compute Unit (ECU) provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.

Amazon offers three instance types: Standard Instance. High Memory Instance. High-CPU Instance.

SummaryCloud Computing is the next big thing in the

arena of computing and storage. There are some concerns about security . However, different service providers are coming up with various solutions and suggestions in response to customers’ concerns.
