Database as a Service - SQL Azure

장현춘, Architect Evangelist개발자 및 플랫폼 총괄, Microsoft Korea

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

The Power of the SQL Data Platform in the cloud

Leverages existing skills and rich tooling ecosystem

Enables database applications with new, “cloud” capabilities

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

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
