Making of a Successful Cloud Business:Current Status & Future Requirements
Rajarshi Bhose and Sumit Kumar BoseInfosys Technologies Limited
Talk Outline
• Cloud Classification
• The Need for Cloud Business
• Challenges in the Current Clouds
• A Viable Cloud Adaptation Strategy
• Conclusion
Infrastructure Cloud Application Platform Cloud
Software As A Service Cloud Private and Public Cloud
CloudClassification
Provides Resources like Compute power,storage, queuing, bandwidth, load balancing
e.g.: Amazon, 3tera
Provides open platforms for developersDevelopers concentrate on High end applications
Without worrying on Clusters and Virtualizatione.g. Google App Engine, Force.com
Private Cloud runs inside the Enterprise
Public Cloud like AWS which any one can pay and useCan also create an Enterprise Cloud
Provides specific Business Applicationse.g.: Cloud CRM, E-Mail, Word Processing. Speed and
Quick setup with almost nil spending on Internal IT.E.g.: Google App, Salesforce.com
Cloud Classification
The need for cloud Business:IT Infrastructure Management Challenges
• Sparse Server Utilization– Volatile demand results in server
sprawl.
• Increased Time To Market for ServerProvisioning– Need for rapid deployment of
infrastructure for development,testing and to experiment andwork out ideas.
• Upfront Buffers leading to CapacityRedundancy
• Long infrastructure delivery time-lines– Driven by elaborate process and
governance mechanisms.
• An economic crisis with renewedfocus on driving down costs.
• Mismanaged Infrastructure budgets
Am I spending too much ???Am I getting good ROI ???Do I have enough resources to meet myon-demand business needs ???Can I quickly provision some newservers to my R/D team for their newideas with out increasing the total cost ofmy IT?
Can some one up in the clouds help ?

Standardization
• Current Issues– Vendor lock ins.– A Single Provider may not meet all customer requirements– Non Portability of code and applications/Inter-operability
of clouds
• What does a customer gain from standardization.– No Vendor lock ins.– Use Heterogeneous services from several clouds.– Cloud Federation– A standard API for accessing and creating applications.
Contd…
• Steps required for Standardization.– All Cloud Vendors should come together and agree on the
standardization requirements.– Form a Committee and drive the effort and necessary
research.– Work with standard bodies like W3C etc.– Vendors should develop API, Applications and Services
based on the standards.

Automated Provisioning
• Commoditization of cloud services require that theprovisioning be completely automated– VM creation and bare metal provisioning– Network and Storage enactment– Automation workflow
• Generic descriptors for provisioning request.
• License management
• Network, storage and VM security

Summary
• Cloud Classification
• Current IT Challenges
• External Cloud Providers– Scalable Infrastructure– Externalize SLAs– Geo Distributable– Costing pegged on Outcome
• Standardization is important for the ultimaterealization of cloud.
Contd…
• Standardization is the first step to realize automatedSLA negotiation
• Automated provisioning is important and critical forcloud realization.
