What is Azure Service Bus & When to Use it in Your Applications

Azure Service Bus is a cloud-based messaging service that helps address this challenge by providing a platform for decoupling applications and services from each other provided by Microsoft. The Microsoft Azure platform provides this service for better scalability, reliability, and flexibility in application development and deployment.
