Azure Service Bus is a fully managed enterprise messaging platform that decouples applications and services, allowing for reliable message delivery and scalability. It supports various messaging patterns, including message queues and publish-subscribe topics, and offers features like dead-letter queues, ordered messaging, and integration with other Azure services. Common use cases for Azure Service Bus include microservices communication, workflows, and asynchronous processing.

 Punctuality
Join the session 5 minutes prior to the session start time. We start on
time and conclude on time!
 Feedback
Make sure to submit a constructive feedback for all sessions as it is very
helpful for the presenter.
 Silent Mode
Keep your mobile devices in silent mode, feel free to move out of session
in case you need to attend an urgent call.
 Avoid Disturbance
Avoid unwanted chit chat during the session.

5. What is Azure Service Bus?
Azure Service Bus is a fully managed enterprise message broker with
message queues and publish-subscribe topics (in a namespace). Service
Bus is used to decouple applications and services from each other,
providing the following benefits:
 Load-balancing work across competing workers
 Safely routing and transferring data and control across service and
application boundaries
 Coordinating transactional work that requires a high-degree of reliability

7. Benefits of Azure Service Bus.
Azure Service Bus offers several benefits that make it a popular choice for building reliable and scalable
messaging solutions in the cloud. Here are some key benefits of using Azure Service Bus:
 Reliable Message Delivery: Azure Service Bus ensures reliable delivery of messages even in the
presence of network failures, crashes, or other transient errors. Messages are stored durably and can
be retried until they are successfully delivered.
 Decoupled Communication: Service Bus allows you to decouple different components and services
in your architecture. This separation enables more flexible and maintainable systems, as changes in
one component do not directly affect others.
 Scalability: Service Bus supports partitioning, which allows for distributing message loads across
multiple partitions. This enables horizontal scalability, ensuring that your messaging system can handle
increased workloads as your application grows.
 Support for Multiple Messaging Patterns:
− Message Queues: Facilitates point-to-point communication, where a sender sends messages to a queue, and a single
receiver processes them.
− Topics and Subscriptions: Supports a publish-subscribe model, allowing messages to be broadcast to multiple
subscribers based on their interests.

8. Benefits of Azure Service Bus.
 Dead-Letter Queue: When messages cannot be processed successfully after multiple
attempts, they are moved to a dead-letter queue. This feature helps with identifying and
handling problematic messages
 Ordered Messaging: Service Bus supports message sessions, which enable ordered
processing of related messages. This is essential for scenarios where message order
matters, such as processing orders or maintaining workflows.
 Session Handling: Messages can be grouped into sessions, ensuring that messages with
the same session ID are processed by the same consumer. This is useful for maintaining
stateful communication.
 Scheduled Messages: Allows you to schedule messages to be sent at a specific time in the
future. This feature is beneficial for sending notifications, reminders, or executing time-
sensitive tasks.
 Integration with Azure Services: Service Bus can be easily integrated with other Azure
services like Azure Functions, Logic Apps, and Web Apps. This integration helps build end-
to-end solutions.
 Security: Azure Service Bus provides authentication, authorization, and encryption
mechanisms to ensure the security and privacy of messages.
