So your company is adopting a "Cloud First" strategy. What do you need to do to get your applications from on-premises to the Cloud? During this session we will explore some of the core concepts of cloud development from Infrastructure as a Service and Platform as a Service. We will look at the differences between on-premises and cloud architectures and considerations to take into account when planning in how to migrate applications or rebuild them in the cloud. We will also cover security, high availability and deployment scenarios.

4. What is the Microsoft cloud?

5. A network of remote servers hosted on the
Internet and used to store, manage, and process
data in place of local servers or personal
computers.
- Bing

6. Microsoft’s offering
Office 365
Dynamics
365
Azure

7. What are objectives of moving
to the cloud?

8. Business drivers
Changing ways of working
Expectations of customers
Expectations of external partners
Cost benefits

9. Hardware
Less hardware
Different user devices
Fewer data centres
Reduced support cost
Increased high availability

10. Software
New features
Increased security
Easier integration
Cheaper scale
Global distribution of resources

11. What is Azure?

12. Microsoft Azure is an ever-expanding set of cloud
services to help your organization meet your
business challenges. It’s the freedom to build,
manage, and deploy applications on a massive,
global network using your favourite tools and
frameworks.
- Microsoft

22. SaaS

23. Considerations
• Follow best practices for customisation
• APIs for access to data can be constraining
• Identity impersonation
• Licences
• Throttling

24. Application lifecycle management
Environments
• Tenant level
• Site Collection
level
• Multiple sets of
resources
• Integration –
Identity
• Licencing
Rollover
• SaaS – no
access to DBs
• Tooling
• GUIDs
Deployment
• Scripted,
repeatable,
automated
• Environmental
differences

25. Disaster recovery and archiving for SaaS
SaaS applications rely on vendor tools
Legislative archiving requirements
Can’t roll back to a point in time
Can’t restore to a different tenant

26. IaaS
