Provisioning & Connecting to SQL Azure

Basic Architecture

SQL Azure Internals

• Each account has zero or more servers– Azure wide, provisioned in a common

portal– Billing instrument

• Each server has one or more databases– It is a logical grouping of databases– Contains metadata for databases and

usage– Unit of authentication– Unit of Geo-location– Generated DNS based name

• A database is what you buy– Unit of consistency– Contains Users, Tables, Views, Indices,

etc.– Most granular unit of billing– Looks just like a SQL Server database

Service Provisioning Model

SQL Azure Topology

Core Database LayerUses shared infrastructure at SQL database and below

Each user database is replicated to one or more servers (configurable based on SLA)Client requests are routed to current “primary server” for read and write operations (based on SQL session)Security, lockdown and isolation enforced in SQL tier

Highly scalable and state-of-the-art HA technologyAutomatic failure detection; client request re-routed to new primary on failure High SLA guarantee using logical replication (hot standby replicas)Automatic management, self-healing and load balancing across shared resource pool

Provides provisioning, metering and billing infrastructure

Security Model

Uses regular SQL security modelAuthenticate logins, map to users and rolesAuthorize users and roles to SQL objects

Support for standard SQL Auth loginsUsername + password

Future AD Federation, WLID, etc as alternate authentication protocols

Security model is 100% compatible with on-premise SQL

Programming Model

Symmetry with SQL Server
