6. What do these three cloud types of cloud have in common?

What do these three cloud types of cloud have in common?
They are all Services
© Microsoft Corporation. All rights reserved.

7. None of them is a physical server that you or your customer own or even rent / have access to.

8. The Cloud is not Hosting

9. The cloud is an vast distributed system
Coupling is the weakness of all distributed systems

10. What exactly is coupling?
Unexpected cohesion / dependencies between components in a system that restrict it’s ability to change
Time based or temporal
Contract or format
Location or endpoint
Sequence or order (of calls)

11. How do you balance the need to connect with the risks of tight coupling?
Service Bus

12. Service Bus is the lines on every Cloud Architecture Visio you have ever seen…

13. Internally we have some big customers
Visual Studio Online
SharePoint Online (and on prem /w Workflow)
Bing Maps
Microsoft IT - a LOT

14. Decoupling Security Queues use Shared Access Signatures
A Policy is the access mechanism
Name, Key, Permission (Send / Receive / Manage)
Tokens are made from Name, Key, URI, Exp Time
Sender & Receiver never directly talk
Sender and Receiver can change tokens and implementations without either knowing

15. Decoupling format boundaries
All messages are BrokeredMessage class
Body is a binary stream
Properties is a typed user property bag
This is a powerful way to describe the contents of the message and processing / routing data
Good ideas: Encoding / format / schema / version
There are also System Properties
Enqueued time, Sequence number, etc.

16. Decoupling time boundaries
Sender and Receiver never need to be online together
They can also work at independent rates, using the queue as a buffer
Messages can have a future enqueue time
TimeToLive can be set on a message or a queue

17. Decoupling error handling
All queues have a Dead Letter for non-deliverable messages
By default this means 10 failed Receive attempts
Can also be enabled for expired messages (TTL)
Headers now contain a failure reason (so you can decide what to do)

18. Styles of Communication

19. 6/1/2019 9:50 AM
Queues
Service Bus queues support a brokered messaging communication model
components of a distributed application do not communicate directly with each other

20. Topics and Subscriptions

Topics and Subscriptions
Service Bus topics and subscriptions support a publish/subscribe messaging communication model
topics and subscriptions provide a "one-to-many" form of communication

22. When do I use the services?

23. Build reliable and elastic cloud apps
6/1/2019 9:50 AM
Build reliable and elastic cloud apps
Dynamic demand is a reality for today's applications
Modern applications must deal gracefully with spikes in load that can be both uncertain or expected
Scale easily and recover from spikes or momentary outages of components.
