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 infrastructure IT Service-centric approach Self-service based usage model Minimally or self-managed platform Consumption-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. Speed Red Tape Reducing cost or driving revenue

Self-service Based Usage Model Self-service abilities: Upload Build Deploy Schedule Manage Report

Self-service Based Usage Model Less administrative involvement More user independence Improves business agility

Self-managed Platform Uses a platform that is self-managed: High levels of reuse Scheduling and reserving resource capacity Config, manage, report for max user assurance Access 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 ( I aaS) 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.
