Cloud Computing

What is cloud computing?

A new generation of computing that utilizes distant servers for data storage and management.

It also allows new devices to use smaller and more efficient chips that consume less energy than standard computers.

Cloud Computing

Characteristics Of Cloud Computing

Dynamic computing infrastructureIT Service-centric approachSelf-service based usage modelMinimally or self-managed platformConsumption-based billing

Dynamic Computing Infrastructure

The infrastructure must be:• Standardized• Scalable• Have a Secure Physical Infrastructure• Ensure high levels of availability• Growth as usage demands it without changes in

architecture• Must be virtualized

Service-centric Approach

Compared to system or server-centric models.SpeedRed TapeReducing cost or driving revenue

Self-service Based Usage Model

Self-service abilities:UploadBuildDeployScheduleManageReport

Self-service Based Usage Model

Less administrative involvementMore user independenceImproves business agility

Self-managed Platform

Uses a platform that is self-managed:High levels of reuseScheduling and reserving resource capacityConfig, manage, report for max user assuranceAccess control list or least privilege for users

Consumption-based Billing

Billing user for only those resources that it used and for the exact amount of time they were used.

Allows detailed and more accurate billing

Types of Cloud Computing

Public

Hybrid

Private

Public Cloud

The main benefits of using a public cloud service are: Easy and inexpensive to set-up because hardware, application, and

bandwidth costs are covered by the provider. Scalability to meet needs. No wasted resources because you pay for what you use.

Private Cloud

Smaller, cloudlike IT systems within a firewall that offer similar services as a public cloud, but to a closed internal network.

Offers more security than public cloud computing

Hybrid Cloud

Contains aspects of both private and public cloud computing.

Allows organizations to keep private or sensitive data in-house and still use public cloud services hosted out-of-house.

Types of Services Offered

Infrastructure-as-a-Service (IaaS)Platform-as-a-Service (PaaS)Software-as-a-Service (SaaS)

Infrastructure-as-a-Service

Raw infrastructure, such as servers and storage, is provided from the vendor premises directly as an on-demand service.

Examples: Amazon Web Services, GoGrid, and Flexiscale.

Platform-as-a-Service

Development platforms and middleware systems hosted by the vendor, allowing developers to simply code and deploy without directly interacting with underlying infrastructure.

Examples: Google AppEngine, Microsoft Azure, and Force.com.

Software-as-a-Service

Complete application systems delivered over the Internet on some form of "on-demand" billing system.

Examples: Salesforce.com, WebEx, and Workday.

Problems With Cloud Computing

Cloud Security Puts your data outside of your organization Trusting in the security of the service provider

Sidekick data loss

T-Mobile’s Sidekick phone’s data is stored on Microsoft’s servers ‘in-the-cloud’.

On October 2, 2009 the servers that held all the data crashed after a failed server upgrade.

There was no backup and now many Sidekick owners lost all of their contacts, calendar entries, to-do lists, and photos.

Conclusion

Cloud computing is an emerging technology There are many benefits to cloud computing but cloud

computing can also have its risks and problems.
