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

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
