Scaling and high availability in Azure Service Bus

Building resilient applications in the cloud demands a strong emphasis on scalability and high availability. These aspects are often interrelated and form the bedrock of efficient cloud solutions. As a powerful messaging platform, Azure Service Bus excels in addressing these vital concerns through various features and capabilities. In this section, we will explore how Azure Service Bus tackles the challenges of scalability and high availability.

Firstly, we will delve into scaling and how Azure Service Bus enables applications to handle varying message workloads efficiently. Azure Service Bus’s scalability is anchored around Throughput Units (TUs) in its Premium tier, which bundles CPU and network bandwidth resources. You can allocate a fixed number or let them auto-inflate based on demand. For enhanced throughput, entities such as queues and topics can be partitioned, distributing messages across multiple copies.
