Trend forecast through 2012: heavy cloud coverageThe top IT trend among press, analysts, conferences…
Consumers: already big, unnoticed, in public online services
Not all enterprises are fully subscribing: constraints vs. benefits
Notion of “private clouds” or “on-premises clouds” has begun only recently(together these yielded only 127 Google search hits on Nov 7th, 2008)
69% of online users are making use of cloud computing
The Cloud Wars: $100+ billion at stake
$0.15 per GB/month
$0.06 per session hour $0.10 per
CPU hour
What is it? What does it do? How to benefit? How it evolves?

What is cloud computing? What is new and different?A concept with many elements, some new, some old
Current state-of-art in the evolution and convergence of many seemingly independent trends
Decoupling of the source of consumption of IT from the source of production
Industrialization of IT
Everything in IT can become affected by as-a-service
Much of what was within the corporate boundaries is being increasingly served up from outside

Need for new concepts: IT is at tipping pointOperational issues have IT costs at break point
Rising costs of IT operationsContinuous increase in volumes24/7 availability of IT
Business changes have IT resources at break point
Budgets being cutDifficulty in deploying new servicesSurge of compliance requirements
New technologies have time-to-market at break point
Unpredictable workloadsDevice diversity, real-timeRich application capabilities
The IT delivery model needs to be transformed
Energy issues have data centers at break point
Rising energy costsPower and thermal issues inhibit growthEnvironmental guidelines

Commoditization
A business is not a free spirit like a consumer
Online services are driving the adoption, growth and new business models

A dose of reality to turn down the noise level Security… sending data outside company firewalls
Privacy… all logons and identities are remote
Platform dependency… lock into proprietary stacks
Reliability… and communication around outages
Portability… data formats and program calls
Physical location… many nations’ laws
Speed.. application latency
Audit… lack of audit capability and governance
Integration… with internal IT infrastructure
Public clouds are not an option for every enterprise

“Pure form” cloud computing will be rare among enterprises
IT will not become 100% as-a-service and not for all
There is a need for delivery flexibility, project by projectProducts and servicesPackaged solutionsManaged infrastructureInfrastructure-as-a-service
Customers decide which IT infrastructure and delivery model is best for themDepending on their particular needs, means and skillsRedefining to what depth they consider information technology as their core and to what level they want to involve their strategic partners in their IT
No one infrastructure delivery model would be optimal for all or every time

How much multi-tenancy would you tolerate?
Sharing and multi-tenancy basically means a trade-off between customer’s sovereignty and costs
Clouds come with a risk that same resources accommodate unanticipated partners & events
How much multi-tenancy can enterprises and public organizations tolerate?
Shared location? Shared infrastructure? Shared operating environment? Shared application server? Shared database? Shared program calls? Shared database admins?
Customers want to know what sort of wrappers public clouds are putting around their services for things like security and policy enforcements

Ground level judgmentCloud is a collection of disembodied resources and services mediated by cloud provider
If IT becomes a borderless utility, it will not matter where your data and programs are stored and executed
Legal and political issues are tricky – even more than with cross-border logistics and taxes
Clouds are prisoners of local laws, no global standards in areas such as privacy
Speed and willingness of authorities from different countries to co-operate
Regulations from several governments forcing online firms to retain data
Enterprise data centersare evolving to improveefficiency
Public clouds
Public clouds providegeneral consumer andbusiness services outside the firewall
Private clouds fornew delivery modelsinside and outsidethe firewall
Enterprise IT
IaaS
What about on-premise or private clouds that act as a cloud to multiple divisions under the corporate umbrella?

Thinking of cloud computing in terms of how, not whereCost savings – new yields in economies of scale
Pay for what you use
Resource flexibility
Increased speed to market
Improved service levels and quality rules
Self-service deployment
Reduce lock-in and switching costs
Enhanced customer experience
Constant application & data availability
Accountable, and policy-based
Dynamic provisioning (expand) andde-provision (shrink) of IT capacity
Executing and completing tasks within the acceptable timeframe (SLA)
Shared infrastructure with ability to ensure data is segregated
The ability to smack someone on the head when something fails
More rules for sharing, more governance influencing sharing, combined with the economics and value of sharing

Private cloud computingMore and more enterprises are expected to build private cloud infrastructures to take advantage of benefits without the risk
IT services are offered to a closed networkof corporate or division offices, and can include business partners and value-chain entities
Cloud-like IT infrastructures that operate behind firewall or use a quarantined partition inside a public cloud
On-premises cloudsOff-premises private clouds
Data/applications do not leave the enterprise
“A fundamental message is that the future of infrastructure looks a lot like private cloud computing.”

Infrastructure-as-a-service: clouds to enterprisesCompelling future
For finished IT services
For attached IT services
For IT service integration
Acquisition model = service based
Business model = usage based
Access model = Intranet or private
Technical model = dynamic
Delivery model = flexible
I am interested in results, not how IT is built
I only want to pay for what I use
I can optimize according to core and context, mission-critical and non-critical systems
I can scale up or down dynamically, as need arises
No single IT delivery model fits all my projects
Next level in IT efficiency gained by unified technology stacks,sharing resources and industrializing services

Summary – a next generation service, not a toolkit technologyCloud computing will change:
The way IT is used and delivered
The ways software is used or licensed
The ways data centers are built and run
Enterprises will not be running IT fully off the Internet cloud
But most enterprises (of all sizes) will come into touch with some form of cloud
Cloud computing as IaaS will become part of the 21st century IT
We aspire to offer most benefits of cloud computing to our customers
We do this via our Dynamic Infrastructures: as a product, as a solution, as a service
Thank You!
