Cloud Computing

The practice of using networks of remote servers on Internet for storage is cloud computing.

How can cloud computing save energy?

Because they use virtualization techniques to separate the software from the characteristics of physical servers, certain costly energy features such as multiple power supplies are dropped.

Fundamental Models/Service Models

Paas

Platform as a service: Cloud providers provide with a computing platform which contains OS, Programming development tools and environment, database and webserver. Application developers can develop and maintain software solutions on this without cost and complexity of buying and maintaing hardware and software. Resources in cloud scale automaticaly to match application demand. Examples: Cloud Foundry,

 Force.com,

Google App Engine,

Windows Azure Compute

 OrangeScape.

IBM SmartCloud Application Services

SaaS

Software as a Service: Cloud providers install software and applications in the cloud and cloud users access the same through cloud clients. Cloud users need not to manage cloud infrastructure and platform. It is managed by Cloud providers.

Features: Scalability, Task cloning on different virtual machines, load balancers, multi tenant.

Applications: desktop aas, communication aas, business process aas, test environment aas.

Typically flat monthly/annual fee.

Demerit – User’s data on cloud provider’s server. Can be unauthorized access.

Exampes:

 Google Apps,

 Microsoft Office 365

 GT Nexus,

 Trade Card

IBM Smarter Cities on Cloud	Enables collaboration and communication among leaders across city operations
IBM Smart Business Desktop	Desktop virtualization delivered on a subscription basis
IBM Social Collaboration for Government	Cloud-based collaboration tools designed in compliance with federal security standards
IBM Coremetrics

NaaS

Cloud service provided in which cloud users can use network/transport connectivity service and/or inter-cloud network connectivity services. NaaS invlolves optimization of allocated resources as it treats resources on the Network as a unified whole.

 

IaaS

Infrastructure as a service

Cloud providers provide with virtual machines. (sometimes physical machines)

Provide additional resources like file storage, image library, local area network, IP address, firewalls, load balancers.

To deploy applications, users install OS patches and softwares on cloud infrastructure.

Cloud providers bill users on utility computing basis for IaaS services.

Examples are :

Amazon CloudFormation,

 Amazon EC2,

 Windows Azure Virtual Machines,

Google Compute Engine

, HP Cloud

Oracle Infrastructure as a Service
