2. Who am I?
Joined in 2005
On-premises and SQL Azure (even back to SQL Server Data Services!)
Moved to Windows 2013 to launch IaaS with a couple (~18 months) stints in Azure AD
Joined CXP in late 2016
If it is a core Azure service, I have probably supported it at some point

3. Agenda What is an IaaS VM? Why do we have IaaS? Creating an IaaS VM
Tips and Tricks

4. Let’s get the premise right!
prem·ise [ prémmiss ]   
basis of argument: a proposition that forms the basis of an argument or from which a conclusion is drawn
prem·is·es [ prémmissəz ]   
land and buildings: a piece of land and the buildings on it
“On-premises” is the correct usage when referring to infrastructure in the local building

6. The beginning… Microsoft Azure:
Microsoft’s cloud platform: a growing collection of integrated services—compute, storage, data, networking, and app—that help you move faster, do more, and save money
IaaS, PaaS, SaaS
Hybrid Ready
Open and Flexible
Always Up, Always On
Economical and Scalable
Everywhere
Windows to Linux, SQL Server to Oracle, C# to Java.
99.95% availability SLA, 24x7 support for everybody
Per-minute billing, commitment to match prices
Europe, North America, Brazil, 1st in China, Australia

Slide Objectives:
Explain the differences and relationship between IaaS, PaaS, and SaaS in more detail.
Speaking Points:
Here’s another way to look at the cloud services taxonomy and how this taxonomy maps to the components in an IT infrastructure.
Packaged Software
With packaged software a customer would be responsible for managing the entire stack – ranging from the network connectivity to the applications.
IaaS
With Infrastructure as a Service, the lower levels of the stack are managed by a vendor. Some of these components can be provided by traditional hosters – in fact most of them have moved to having a virtualized offering.
Very few actually provide an OS
The customer is still responsible for managing the OS through the Applications.
For the developer, an obvious benefit with IaaS is that it frees the developer from many concerns when provisioning physical or virtual machines.
This was one of the earliest and primary use cases for Amazon Web Services Elastic Cloud Compute (EC2).
Developers were able to readily provision virtual machines (AMIs) on EC2, develop and test solutions and, often, run the results ‘in production’.
The only requirement was a credit card to pay for the services.
PaaS
With Platform as a Service, everything from the network connectivity through the runtime is provided and managed by the platform vendor.
The Windows Azure best fits in this category today.
In fact because we don’t provide access to the underlying virtualization or operating system today, we’re often referred to as not providing IaaS.
PaaS offerings further reduce the developer burden by additionally supporting the platform runtime and related application services.
With PaaS, the developer can, almost immediately, begin creating the business logic for an application.
Potentially, the increases in productivity are considerable and, because the hardware and operational aspects of the cloud platform are also managed by the cloud platform provider, applications can quickly be taken from an idea to reality very quickly.
SaaS
Finally, with SaaS, a vendor provides the application and abstracts you from all of the underlying components.

10. IaaS Components Compute Storage Networking Various hardware resources
Stock OS images
Custom OS images
Storage
Networking

11. Compute Provides stock images, plus stock deployments
SQL plus Always On
SharePoint Dev plus SharePoint farm
Linux
Oracle on Windows/Linux
SAP
Also upload custom images
For Windows, Sysprep plus tiny bit of Azure
For Ubuntu,
Etc.

12. Payment Options
Pay as you go
Monetary commitment
Enterprise agreement

13. Compute
xS = Premium disks

14. Who wants swag?

16. Let’s create some VMs – Part I
Demo
Create some VMs

17. Myths and Misperceptions
Hyper-V and System Center
Just a black box
Only for new apps
Not standard Windows/Linux

18. Azure
It’s just Windows/SQL/etc.

19. On-premises

20. Not really a Cloud problem
-> 3%
Azure
On-premises

21. Myths and Misperceptions
Hyper-V and System Center
Just a black box
Only for new apps
Not standard Windows/Linux
Just for Windows/Microsoft

22. It’s all in the name… Microsoft Azure, not Windows Azure
It is very few people’s core business to run servers and applications (and will be less in the future)
We will still make money in the future off licenses, but we will also make money off IaaS, PaaS, and SaaS.

23. Demo Let’s modify some VMs
Show the created VMs and that they can be resized on the fly.

24. Tips and Tricks
Security
Restarts
Azure and O365

25. “Secured” Virtual Machines
VMs are exposed to the internet via their IP
NSGs – secure by default
Endpoints are easily disabled
Follow all standard best practices but remember
Strong password != easily guessable

26. Virtual Machine restarts
1 VM = no SLA
Manage by leveraging availability sets
Most restarts are due to hardware failures
Hardware is expected to fail
Microsoft is investing in predictive tooling (ML)
Still not perfect
Still might require a restart, but not an unexpected one
Azure Scheduled Events

27. Azure + Office 365 ADFS is a fully supported scenario
Make sure you have at least 2 DCs in Azure
Careful if federating your Azure subscription
If ADFS goes down, cannot log in to fix it
Just like O365, always keep at least one unfederated account
Follow best practices -
Consider ditching ADFS
