What is the Windows Azure Platform Scenarios for Azure Strategies for Moving to Azure Challenges and Opportunities
Currently 6 data centres in 3 regions Europe, US, Asia
Purpose-built data centre to accommodate containers at large scale Cost $500 million, 100,000 square foot
facility (10 football fields) 40 foot shipping containers can
house as many as 2,500 servers Density of 10 times amount of
compute in equivalent space in traditional data centre
First Mega Data Centre built outside the US, on-line on July 2009 Cost $500 million, 303+sq ft facility and
growing EU data centre Best Practice Award Winner Stand-alone Server Pods
▪ Environmentally Sustainable ▪ Free Air-Cooling via Air-Side Economization
50% less energy use vs. traditional facilities 1 % water use vs. traditional facilities 1.25 PUE 5.4 Mega Watts today, 22.2 MW for future
use ISO 27001:2005 Accreditation SAS 70 Type I and II Attestations

Delivery
Network
Compute
Development, service hosting, & management environment .NET, Java PHP, Python, Ruby, native code (C/C++, Win32, etc.)
ASP.NET providers, FastCGI, memcached, MySQL, Tomcat
Full-trust – supports standard languages and APIs
Secure certificate store
Management API’s, and logging and diagnostics systems
Multiple roles – Web, Worker Multiple VM sizes
1.6 GHz CPU x64, 1.75GB RAM, 100Mbps network, 250GB volatile storage
Small (1X), Medium (2X), Large (4X), X-Large (8X)
In-place rolling upgrades, organized by upgrade domains Walk each upgrade domain one at a time
No remote desktop management or access to physical resources
Rich data abstractions – tables, blobs, queues, drives, CDN Capacity (100TB), throughput (100MB/sec), transactions (1K req/sec)
High accessibility Supports geo-location
Language & platform agnostic REST APIs
URL: http://<account>.<store>.core.windows.net
Client libraries for .NET, Java, PHP, etc.
High durability – data is replicated 3 times within a cluster High scalability – data is automatically partitioned and load
balanced across servers
Storage Storage
Data
Highly available, scalable, and consistent distributed relational database; geo-replication and geo-location of data
Relational database, provided as a service Highly symmetrical development and tooling experience (use TDS protocol and
T-SQL)
Highly scaled out, on commodity hardware
Built on the SQL Server technology foundation
Editions: Web (1GB), Business (10GB)
Connectivity Service Bus
Securely connect applications Over the internet
Across any network topology
Across organizational boundaries
Primary application patterns Eventing – notify applications and/or
devices
Service Remoting – securely project on-premises services out to the cloud
Tunneling – app-to-app communication with NAT/Firewall traversal
Manage explosive growth Limit capital expenditure

Greenfield Start-up or application
Migration Full applications or part Service oriented architectures Distributed applications Loosely couple application architectures Few architectural compromises
Extension Provide extra capacity Split architecture
.NET 3.5 SP1 or .NET 4.0 IIS 7.0 64 bit ASP.NET web application (not web site) Core SQL Server components Abstract logging, configuration etc Avoid using O/S features Avoid legacy code and applications
(especially any that require installs)
Stateless Asynchronous Distributed Design for failure
Hardware
Network (e.g. blips)
Compute Web and worker role often biggest cost 2 required for SLA Consider on/off for tasks Group tasks together under single role
Compression Reduce data storage cost Reduce bandwidth cost Improve performance and latency for data read/write
Data Consolidate database Migrate to table/blob storage from SQL Azure
Data Data portability issues
Migrating data
How much does data sovereignty matter
What data would you never put in the cloud Security
Does data in the cloud pose a security risk compared to on-premise
Shared hardware impacts security
Data/hardware destruction policies
Legislative Data protection laws
Taxation treatment
Jurisdiction challenges
Compliance requirements Availability
Sending data over the Internet is slow
The Internet is not always available
Reliability in service providers’ hands
Not a “magic bullet” for current scalability issues
No in-built SMTP/FTP support No out of the box backup or DR (yet)
Server patching managed by platform Deployment and environment managed by
platform Monitoring managed by platform Familiar development environment Symmetrical platform Massively scalable Highly flexible model Pay per usage 3 fold durable data storage Interoperable
