Agenda
• What is Cloud?
• Benefits of the cloud
• Cloud deployment models
• Who are the players?
• Recommended Approach
What is Cloud Computing?
“Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and
information are provided to
computers and other devices as a metered service over a network (typically the Internet).”
Wikipedia Definition
It’s an Operating System in the Internet.
• Pay-per-use for computation power.
• Virtually infinite computation resources
• Automatic on-demand scalability Simple Answer
“Computation Power” is now available like
Electricity
You pay for what you use.
You rely on trusted third-party providers
An Analogy - Electricity
Evolution of Cloud Computing
Grid Computing
Solve large problems with parallel computing.
Utility Computing Offering computing resources as a metered service.
Software as a Service Network-based subscriptions to applications.
Cloud computing break out
Why cloud computing?
Reduces Ownership Cost
• Savings on Capital Investment
• Savings on Data center space, power and cooling.
• Minimizes operations costs
Better Budget Utilization
• Reinvest saved Capex on new initiatives
• Focus on business not on infrastructure
• Save on operations man power.
High Scalability/Elasticity
• Eliminates capacity planning and sizing
• Prevents ‘success disaster’
• Add, Subtract capacity as network load dictates
Quality
• Skilled practitioners (Microsoft Google, Amazon etc.)
• Quality of service
• Easy implementation
Cloud Characteristics & Deployment Models
Pooled Resources Broad Network
Access Elastic Pay per use
Self Service
Public Cloud
• Resources are made available to the general public by a service provider
• The customer has no visibility or control over the computer
infrastructure.
• Examples of public cloud are Windows Azure, Amazon EC2 etc.
Private Cloud
• All the 5 Characteristics of
Cloud + Control & Customizable.
• Infrastructure operated solely for a single organization
• On-premise or third party.
• Example MS ECI Datacenter, VM Ware
Community Cloud
• Sharing infrastructure between several organizations from a specific community.
• Managed internally or outsourced to a third party.
Hybrid Cloud
• A composition of two or more clouds
Public vs. Private Cloud
Private Cloud
• Exclusive environment
• Limited on-demand capabilities
Public Cloud
• On-demand resources, scalability
• Shared environment
On-Premise Private Cloud
• Exclusive environment
• Limited on-demand capabilities
Externally Hosted Private Cloud
• Exclusive, but hosted by a third party
• Limited on-demand scaling
• Expensive than public cloud
• Cheaper than on-premise private cloud
• Possibility of co-location
Hybrid
Public + Private
Cloud Deployment Example – A Web Application
Web Application on Premise Web Application on Azure
Web server farm
Internet
Storage
Database Server
• Load balanced webserver farm, SQL Server & Storage devices on premise.
• Fixed number of servers on the web farm.
Web Role Instances
Azure SQL Azure Storage
• In the best case scenario, no components need to stay on premise.
• Web role instances can be scaled up/down based on the load.

• No static IP Addresses
SQL Azure
• Full featured RDBMS.
• Can be accessed from Windows Azure or On-premise applications.
• Microsoft takes care of administration.
• Use data synch feature to synchronize to on-premise database if required.
• Works almost like on-premise SQL Server except for few features such as full text search (SSRS in Beta)
Azure Storage

Storage
Database Server
• Maintained our own Web & SQL Servers at a data center.
• Needed staff to trouble shoot infrastructure issues.
Web Role Instances
Azure SQL Azure Storage
• Deployment with 2 Web instances and SQL Azure.
• App Fabric Cached used for implementing session memory.
Data Center Windows Azure
Risks, Concerns & Challenges
• Security
• Data Governance
• Utilization of the capacity.
• Reliability and Availability.
• Latency
• Integration with existing tools.
• Regulatory Compliance.
– Location of data.
– PCI DSS Compliance (Credit Cards) – HIPPA Compliance
Recommendations on Approach
• Get Risks on the table early. Turn them into green or fail fast.
• Very important to involve all stake holders from Operations as well as Security
teams.
• Be aware that it may not be practical to move everything to Cloud.
• Identify top Technical blockers or areas that may take inhuman effort.
• Shortlist Likely Candidates for Cloud Migration.
Identifying Likely Candidates
• Applications that do not depend on infrastructure or other applications (E.g. Email,
Office)
• Applications that are not frequently used.
• Applications that have varying degree of demands
– Need more horsepower in Holiday season
• Systems that incur huge costs for hardware, software and support contracts.
• Back up services running only in the night
– Schedule the backup service and pay for that time only.
• Applications that are shared across the globe.
– Use MS Office in US and India at different times. Pay for one License.
