클라우드 컴퓨팅이란 ?
• Definition– Providing IT resources, as a service, in a dynamic and scalable
manner over a network
• What does this mean?– Access from any device (PC, Phone, Multi-Function Devices, TV…)
– Hosted centrally managed software and data– Unlimited processing, CPU, storage, memory, data centers– IT on demand
• *Five essential characteristics of the Cloud: – On-demand self-service – Broad network access– Resource pooling– Rapid elasticity – Measured service

SQL Azure Database
Customer Value Props
Self-provisioning and capacity on demand
Symmetry w/ on-premises database platform
Automatic high-availability and fault-tolerance
Automated DB maintenance (infrastructure)
Simple, flexible pricing – “pay as you grow”- AD Federation (LiveId /AppFabric AC)
Relational database service
• SQL Server technology foundation
• Highly symmetrical
• Highly scaled
• Highly secure
Database “as a Service” – beyond hosting
Highly scaled out relational database as a service

가능한 시나리오들
• Departmental Applications– Simple application built by individual or department– Need simple deployment, self-management, IT: “Empowermen
t and Governance”
• Web Applications– Small business or startup that uses the cloud as their IT– Simple deployment, self-management, scale on demand
• ISV– ISV hosting software on behalf of customer– Multi-tenant support for billing and isolation
• Data Hub (Shortly After V1)– Sharing and aggregating of data across tiers and across enter
prises– Centralized place for data, high scale, sync with existing data
sources

SQL Azure Service Provisioning
• Each account has zero or more servers– Azure wide, provisioned in a common portal
– Billing instrument
• Each server has one or more databases– Contains metadata about the databases and u
sage
– Unit of authentication and Security
– Unit of Geo-location
– The server is a logical grouping of your DBs
• Each database has standard SQL objects– Unit of consistency
– Contains Users, Tables, Views, Indices, etc.

SQL Azure 사례 - EHA
• Exchange Hosted Archive (EHA) is high scale archival service
• Runs on SQL Azure infrastructure
– In production prior to SQL Azure v1
• Rebuilt to address cost and scale issueshttp://www.microsoft.com/casestudies/Case_Study_Detail.aspx?CaseStudyID=4000003098
Reduced COGS with increased customer and business benefit: Larger scale (e.g. larger customers ~20TB+ each)
More self-managing (e.g. fault-tolerance)
Better query performance for fan-out
Faster provisioning of new customers
