5. Azure Service Bus
Azure Service Bus (Messaging as a Service - MaaS) is an asynchronous cloud delivery messaging service,
and offers a secure data transfer between different applications.
Namespace
Queues Topics
Protocols
AMQP
HTTP-HTTPS
Many Front End applications send
messages to the queue and one
application on the back end serves
those requests in order of priority,
This is a publish-subscribe model,
push the message into a topic and
that message sent to all subscribers
one to many, e.g Twitter or Facebook
feeds.
 Cross platform
compatibility with
many clients
 Provide
communication
where firewalls may
limit connectivity on
other protocols.
 Ports 80 & 443
 Default protocol used
by Service Bus SDK
 Supported by many
apps
 Open messaging

 Ports 5671 & 5672

6. Enterprise Service Bus
“An enterprise service bus (ESB) implements a communication system between mutually interacting
software applications in a service-oriented architecture (SOA). It represents a software architecture for
distributed computing, and is a special variant of the more general client-server model, wherein any
application may behave as server or client.”

Azure Service Bus Features Per Tier

11. Feature Description
Message sessions Sessions are grouped related messages and processed together, also
sessions can guarantee FIFO sorting
Duplicate detection Duplicate messages can be ignored by a messaging entity
Message deferral Messages can be preserved on a messaging entity and retrieved later
for processing
Dead-lettering Invalid or poison messages can be moved to a dead-letter queue
Message expiration Messages can be configured to expire after a specified duration
Batching Messages can be sent in a single batch, during a period of time delay
on a queue or a topic
Scheduled delivery Messages can be start processing at a certain time after a delay.
Auto-forwarding Automatically removes a queue or subscription to another queue or
topic in the same namespace.
Filtering and actions The subscriber can filter which message want to receive from the
topic.
Azure Service Bus Advanced Features

12. Service Bus Tools
1. Azure Portal
2. Visual Studio
3. Visual Studio Code
4. Service Bus Explorer

13. To keep in the mind…
 Think what do you want to do before decide what is the appropriate Service Bus .Net SDK
 It is a wise option to select AMQP protocol
 Use concurrent operations
 Use multiple queues/Topics

14. Azure Service Bus .Net SDK
WindowsAzure.ServiceBus Microsoft.Azure.ServiceBus
The old…. The new….
• AMQP, SBMP, HTTP
• .Net Framework 4.6.1
• Primary Namespaces:
• Microsoft.ServiceBus

var messageTwo = new Message(body);
var sendFirstMessageTask =
queueClient.SendAsync(messageOne).ContinueWith(_ =>
{
Console.WriteLine("Sent message #1");
});
var sendSecondMessageTask =
queueClient.SendAsync(messageTwo).ContinueWith(_ =>
{
Console.WriteLine("Sent message #2");
});
await Task.WhenAll(sendFirstMessageTask,
sendSecondMessageTask);
Console.WriteLine("All messages sent");

var messageOne = new BrokeredMessage(body);
var messageTwo = new BrokeredMessage(body);

var sendSecondMessageTask =

Concurrentoperations
Usually operations like send, receive, or delete, takes time. To reduce this latency it is best practice to use
Concurrent operations, because with that way we can increase the number of operations.

16. Multiple queues/Topics
If we cannot predict the application load we can use multiple messaging entities,
More than one queues or topics.
