Myths..

• It is not safe to move to Cloud.. Security???• We will be locked into one vendor and lose

control of its data, if it moves to the cloud.• My company must move all its applications to

a cloud service to be able to benefit fully from cloud computing.

• Only a small business can gain any cost savings benefit out of Cloud Computing.

“ An approach to computing that’s about internet scale and connecting to a variety of devices and endpoints ”

Microsoft’s view of Cloud

16

Windows Azure

17

Windows Azure – provides• Environments for your apps• Machines, rack space, switches, connectivity• Automated deployment & configuration• Isolation, redundancy,

load balancing• Abstraction & Flexibility

Windows Service roles (Compute)

Web Role Worker Role

22

Windows Azure Storage

Scalable storage in the cloud• 100tb per storage account• Auto-scale to meet massive volume and throughput

Accessible via REST services• Access from Windows Azure Compute• Access from anywhere via internet• Supporting .NET Client Library

Various storage types• Table - group of entities (name/value pairs)• Queue - Simple non-transactional message queue• Blob - Large binary storage • Drives - NTFS VHD mounted into Compute instance

23

SQL Azure Database• SQL Server relational database model

delivered as a service– Support for existing APIs & tools– Built for the cloud with high availability &

fault tolerance– Easily provision and manage databases

across multiple datacenters

• SQL Azure provides logical server– Gateway server that understands TDS

protocol– Looks like SQL Server to TDS Client– Actual data stored on multiple backend data

nodes

Building Block Services

24

Authn support using multiple identity providersEasily integrate Live ID, Facebook, Yahoo, Google, & ADSupport for industry standards and existing .NET APIs

Messaging & connectivity for building distributed and loosely-coupled apps in the cloudEnables hybrid apps across both on-premises & the cloudQueues & Topics for persistence & pub/sub messaging

Distributed, in-memory cache for Windows Azure appsSession state provider for Windows Azure applications.NET client library for caching data

Access Control

Caching

Service Bus

25

Data Services

– Synchronize data from on-premises SQL Server to/from SQL Azure in the cloud

– Synchronize data between SQL Azure databases potentially in different data centers

– SQL Server Reporting provided as a service – Reports authored using existing tools (BIDS) – Reports can include rich Data Visualizations (Maps, Charts,

Tablix) and exported to variety of formats

– Directly viewed in the browser or rendered as part of an app using the Reporting Viewer control

– Web Service interface to render & manage reports

Microsoft Azure Data Centers

• Windows Azure runs on 8 datacenters around the world• Enabling you to deploy and run applications and infrastructure close to your

customers.
