What is Cloud Computing?

It is a user experience

Cloud computing is an emerging style of computing in which

applications, data, and IT resources are provided as services to users

over the web.

Cloud principles will bring a level of standardization to

infrastructure management methodology

Cloud computing drives cost reduction and simplification, by

consolidation and more efficient utilization of existing resources

It is a business model

How often can you say no?

How effectively do you charge the lines of business you support?

What is Cloud Computing?

U.S. National Institute of Standards and Technology:

Cloud computing is a model for enabling convenient, on-demand

network access to a shared pool of configurable computing resources

that can be rapidly provisioned and released with minimal management

effort or service provider interaction.

Resource pooling Broad network access Rapid elasticity

Measured service On-demand self service

Characteristics

Software as a Service Platform as a Service Infrastructure as a Service

Service Models

Private cloud Public cloud Hybrid cloud

Community cloud

Deployment Models

Common Attribute Details

Flexible pricing Utility pricing, variable payments, pay-by-consumption and

subscription models make pricing of IT services more flexible

Elastic scaling Resources scale up and down by large factors as the demand

changes

Rapid provisioning IT and network capacity and capabilities are ideally automatically rapidly provisioned using Internet standards without transferring

ownership of resources

Advanced virtualization IT resources from servers to storage, network and applications are

pooled and virtualized to provide an implementation independent,efficient infrastructure

Standardized offerings Uniform offerings readily available from a services catalog on a

metered basis

IBM Premise: Cloud Computing Must Have

Why is Cloud Computing Important?

Your User Community is doing it

Submarine Projects are currently underway in your business

Youve Been here before

Remember when those pesky Windows based Web Servers did this?

Your User Community views you a a commodity.

The CSI effect.

Your User Community thinks Cloud can do Everything.

Who needs traditional IT?

Your User Community may be nave.

Eroding good name of the company.

Lets Look At Cloud Computing!

Client says, Cloud will solve my IT problems!

What are the pros and cons of cloud?

What are the things we need to keep in mind?


7/12



The Cloud Important Questions / Points

What do you mean by Cloud?

What problems are you having?

An elastic expense:

Lower cost up front; more expensive in the long run

Clients think, If I go Cloud, then I dont need processors.

Cloud will solve infrastructure problems.

Public Cloud Positives

Easy to Access

Easy to use there is Internet everywhere

Can be accessed from almost any platform

Any Device

Dynamic Projects short term use

Low Cost

Opex verses Capex

Resources are always available

More complete use of the resources

Follow on products

Ability to track trends and pattern usage

Quick startup


9/12



Public Cloud Negatives

Security

End user can bypass IT governance

No guarantee of performance

Need to trust provider

Lack integration with existing system

No guaranteed backup

Dependency on this party

Vendor lock in

Compliance local regional national laws

Lack of customization

Data source integration

Multiple providing the same or similar services

Too many cloud providers cause integration issues

Hacking and Cracking


10/12



Private Cloud Positives

Dynamic peak loading support for applications Provisioning and de provisioning

Time to value

Flexibility

Better resource allocation

Remove server huggers

Easy growth

Have new programming paradigms

Check pointing

Remove single instance team management

Cost is shared

Security is easier public

Improved CapEx and Opex bottom line

Quicker response to respond quicker to market changes

More and easy tests available

Easier platform support


11/12



Private Cloud Negatives

GETTING PEOPLE TO SHARE

Cost money to start

Quarterly/ yearly cost cuts affect deployment

Organization design

Who is responsible for configurations in fuzzy spaces Standardize

System management model

Disparate infrastructure supporting different lines of business

Capacity planning

Stuck with vendor API

Enterprise Architecture is a real need

Governance is key

Problem determination

End to End Cloud Computing IssuesConsider Disaster Recovery

Replication between machines in a room is not DR

Compliance

How will Cloud providers put you at risk

Security

Secure the data.

Multi Tenancy issues

Selecting appropriate workloadsCloud technical models do not solve all problems.

Translating what you know into corporate value

Legal definitions of technical issues
