THE FUTURE MOVING FORWARD
CLOUD COMPUTING
• More servers and bandwidths are needed!
Azure or not Azure?
Quoted from Boon Sheng
WebBytes, Malaysia ISV on Azure
“Well, when people ask me how many
servers do we have, I answered,
how many you need?”

Latency Requirements
Data Sensitivity
Some Easy Cases e.g., web site sharing public data SLA Requirements
Regulation & Compliance
Often, Forklift Approach
Careful decomposition needed

IDENTITY CHALLENGES
Cloud App
Active Directory
• User – Doesn’t want to use different identity for every app
• Developer – Doesn’t want to write code to support multiple identity providers
• Administrator – Wants to easily grant access to apps to Active Directory identities
IDENTITY SOLUTION:
CLOUD SINGLE SIGN-ON WITH ACCESS
CONTROL
ADFS 2.0 AC
Active Directory
• User – Can use his preferred Identity Provider
• Developer – Writes one set of code to accommodate multiple Identity Providers
• Administrator – Grants access to all Active Directory users by establishing trust
between Active Directory and Access Control

Cloud App
CONNECTIVITY SOLUTION (1):
EXPOSE ON-PREMISES SERVICES THROUGH THE
SERVICE BUS
Partner
Cloud App
Extend reach of existing on-premise services to facilitate greater
collaboration between partners, branch offices, remote workers and devices
CONNECTIVITY SOLUTION (2):
ENABLE REAL-TIME BUSINESS PROCESS VISIBILITY WITH
SERVICE BUS
Use the cloud as an efficient way to connect and inform the participants
in Business Processes that span multiple entities across organizational
boundaries

SQL AZURE DATA SYNC (CTP)
• Powers movement of data
• Cloud ⇔ cloud SQL
• On-premises ⇔ cloud Azure
• Getting data where you need it
• Sync SQL Azure instances
Sync SQL Server to SQL Azure
•
• Sync offline apps to SQL Azure
Sync
• Enable geo-replication of data

WINDOWS AZURE CONNECT (CTP)
Virtual Network
• Provides seamless, secure IP-level network connectivity between Windows
Azure and on-premise resources
• Connecting to cloud resources (roles) for administrative purpose

WHERE TO START
• Move existing application to Azure
• Start from small, low-risk application to the cloud
• Gain experience from it.
• This migration may be partial
• Make Azure the default for new application
development
• Codes from Azure can be migrated/reused for on-premise.
• The difference is the usage of Azure specific technologies ie Azure
storage. Create components to cater for this differences (ie when on
premise use file system. Cloud – call blob storage)
• Move Critical Applications
• Migrate critical application on the Cloud
