Service Bus Relay
• Service Bus acts as an intermediary, or bridge, between
Sender and Receiver
• Coupling exists between Sender and Receiver
• Not very forgiving
• Little or no network configuration is required to support
Service Bus
• In most scenarios, outbound Firewall ports do not need to be
opened
• No inbound Firewall/NAT ports required
• Existing Firewalls continue to secure Datacenter access
• Integrated with WCF Programming Model
• Commercially available since Q1 2010

Outbound Connection
Service Bus Queues
• Queue is “durably” hosted in the Azure Cloud
• Decouples Sender from Receiver
• Is more forgiving than Relay Service
• Load Leveling
• Disconnected Clients
• Messages are sequenced in order
• Max Queue size is 5GB
• Max Message size is 256KB
• Sessions allow you to “string” messages together
• APIs include .Net,WCF,REST, AMQP, Node.js, Java…
• Commercially available since Q4 2011

Hello Service Bus demo
Service Bus Topics
• Similar to Service Bus Queues
• Pub/Sub Capabilities
• SQL92 statements
• Currently there is support for up to 2000 subscriptions per topic
• Send same message to multiple subscriptions provided
rule criteria is met
• Can have competing consumers on each subscription
• Topic – Queue Forwarding is supported
Service Bus Topics – Multiple Subscribers

Advanced Capabilities (Queues & Topics)
• Correlation• Sessions
• Reply-To Queues
• Message ID
• Transaction support• Both Send and Receive operations can be committed atomically
• Message Duplication Detection
• Time to Live (TTL)
• Scheduling
• Forwarding
• Receive Modes• PeekLock
• Abandon
• Complete
• Receive and Delete
• Dead Letter Queue
Demo Scenario• Deregulated Power Generation company who has energy for sale
• Power Generator commitment includes:
• Declared: Potential amount of Power available
• Dispatched: Actual amount of Power that is being generated
• Some small variance is expected
• When a generator doesn’t meet their commitment there are
penalties $$$
• Plant Managers require visibility via Mobile device

Event Hubs• Highly scalable publish-subscribe ingestor
• Capable of processing millions of events per second
• Transform and store data using real-time analytics providers
• Pluggable batching/storage adapters (Stream Analytics)
Summary
• Service Bus is an enabler technology
• Hybrid Connectivity
• Cloud based messaging
• IoT ingestion
• Pub/Sub
• Inexpensive
• $0.0528 per million operations (Basic Tier)
• Interoperable
• AMQP
• REST
• Vast client library support
