1 - What is Azure Service Bus and how does it work?

Azure Service Bus is a cloud messaging service that enables communication between applications, services, and devices. It provides asynchronous messaging capabilities using a message queue or topic architecture. Messages are sent to a queue or topic by a sender application and received by a receiver application. The service bus ensures reliable message delivery and supports message publishing and subscription mechanisms.

2) What are the key components of Azure Service Bus?

The key components of Azure Service Bus include queues, topics, subscriptions, and rules. Queues provide point to point communication between a sender and a single receiver, while topics allow for one to many communication by allowing multiple subscribers to receive messages. Subscriptions define individual filters on topics to receive specific messages, and rules provide additional filtering capabilities.

3) How does Azure Service Bus handle message delivery and guarantees?

Azure Service Bus uses a message delivery mechanism that ensures reliable message delivery, even in the case of failures or network interruptions. Messages are persisted in the service bus until they are successfully delivered to the receiver application. The service bus provides features such as message locking, message deferral, and dead letter queues to handle message processing failures and retries.

4) What are the different types of messaging supported by Azure Service Bus?

Azure Service Bus supports two main types of messaging patterns: Point to point (Queues) and Publish/Subscribe (Topics). Queues enable one to one communication between a sender and receiver, while topics allow multiple subscribers to receive messages based on subscriptions and filtering rules.

5) How does Azure Service Bus ensure message security and compliance?

Azure Service Bus provides various security features to ensure message confidentiality, integrity, and compliance with regulatory standards. These features include shared access policies, integration with Azure Active Directory, transport level security using Transport Layer Security (TLS), and message encryption capabilities.

6) How can you monitor and track messages in Azure Service Bus?

Azure Service Bus offers monitoring and tracking capabilities through metrics, alerts, and diagnostic logs. You can use Azure Monitor to track metrics such as message delivery rate, latency, and errors. Additionally, you can configure alerts based on specific metric thresholds and analyze diagnostic logs for detailed message processing information.

7) What are the different pricing options for Azure Service Bus?

Azure Service Bus offers different pricing tiers based on usage requirements, such as Basic, Standard, and Premium tiers. Each tier offers varying features and capabilities, such as message size limits, message throughput, and availability SLAs. Customers can choose the appropriate tier based on their messaging needs and budget constraints.
