Business Case

Your business is growing exponentially. Your computing need & usage is getting bigger with every passing day. Would you add servers & other hardware's to meet the new demand? Assume, Recession is back & your business is losing customers. The servers & hardware's you added during last quarter’s peak season is now idle. Will you sale them? season is now idle. Will you sale them?

That’s where Cloud Computing comes to rescue you !!

Demand keeps on changing based on world/regional economy, sometimes seasonal traffic burst as well. What will you Do?

What is Cloud Computing?

In late 90s or even now, ask any web developer, solution architect or anyone involved in web application development in any capacity: Which symbol do you use to represent Internet on numerous white-board meetings? Obviously the most widely used metaphor for Internet was/is Cloud. Cloud computing has derived its name was/is Cloud. Cloud computing has derived its name from the same line of thinking.

Cloud Computing is a *style of computing which must cater to the following computing needs:

• 1. Dynamism
• 2. Abstraction
• 3. Resource Sharing

* Gartner’s phrase

A Working Definition of Cloud Computing by NIST

“ Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. “

What is the purpose and benefits?

Cloud computing enables companies and applications, which are system infrastructure dependent, to be infrastructure-less. By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment! Clients can: Put their data on the platform instead of on their own desktop PCs and/or on their own servers. They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc.

Types of Cloud / Cloud Deployment Models

• Public cloud

– Sold to the general public, mega-scale infrastructure

• Private cloud / Internal cloud
• Private cloud / Internal cloud

– enterprise owned or leased

• Hybrid cloud

– composition of two or more clouds, part of the service infrastructure runs in private clouds while the remaining part runs in public clouds

Software as a Service (SaaS)

Service-driven business model

Infrastructure as a Service (IaaS)

Platform as a Service (PaaS) Service (SaaS)

Refers to on-demand provisioning of infrastructural resources, usually in terms of VMs. End user has full controls over the virtualized computer instance, and can customize the instance accordingly.

This is the base layer of the cloud stack.

Infrastructure as a Service (IaaS)

and can customize the instance accordingly. IaaS is charged on a utility basis depending on the consumption

• f the resources.

Advantages: Pay per use, Instant Scalability, Security, Reliability, APIs Examples: Amazon EC2 and GoGrid.

Refers to providing platform layer resources, including operating system support and software development frameworks. It delivers a computing platform and solution stack as a service. Hides all the complexity of managing the underlying hardware,

Platform as a Service (PaaS)

Hides all the complexity of managing the underlying hardware, provides all the facilities required to support the complete lifecycle

• f building and deploying web applications and services entirely

from the internet. Examples: Google App Engine, Microsoft Windows Azure and Force.com.

Refers to providing on demand applications, Provider delivers its software as a service to be used by customers on demand. All the functions of a sophisticated traditional application to many customers through a Web browser.

This is the Top most layer of the cloud computing stack - directly consumed by end user.

Software as a Service (SaaS)

many customers through a Web browser. Little or no code is running on the Users local computer. Eliminates customer worries about application servers, storage, application development and related, common concerns of IT. Examples: Salesforce.com, Rackspace and SAP Business By Design.

Some Commercial Cloud Offerings

Amazon Web Services (AWS) is a set of cloud services, providing cloud-based computation, storage and other functionality that enable organizations and individuals to deploy applications and services on an on-demand basis and at commodity prices. Amazon Web Services’ offerings are accessible over HTTP, using REST and SOAP protocols.

Google is the leader in search services on the Internet and has a significant presence and properties in advertising, collaboration, e-mail, and social networking sites. Google has massively scaled data centers with customized caching algorithms that host the fastest search engine in the world.

Google's gmail offers users to host their emails on Google servers, besides providing a web interface to access them. Gmail is free for individuals. For business users, Google docs is a web-based software for building documents. It has the functionality to build text documents, spreadsheets and presentations Google calendar is a browser based scheduler. Its feature set is rich and includes

Google offerings in Software as a Service (SaaS).

feature set is rich and includes daily/weekly/monthly view, multiple calendars for a user, and ability to search events. Picasa is a free Google tool to edit images. Picasa allows you to upload and share images and videos on Google's data centers. Google Groups allows users to host discussion

• forums. Google Groups allow users to create

messages online or via email. Access to Google Groups is completely free

In the Platform as a Service (PaaS) space Google is a market

• leader. Google AppEngine is Google's offering in the PaaS space.

Google AppEngine is a developer platform hosted on Google's cloud The database available is a non- relational database. Database can be accessed with GQL

Google offerings in Platform as a Service (PaaS).

Database can be accessed with GQL (Google Query Language). GQL has SQL like syntax.
