Serverless computing is ideal for high-volume, transactional workloads that don’t require persistent infrastructure.

Developers are accelerating their use of serverless architectures like Azure Functions to speed up deployments (update a function definition and kick it off within seconds), scale instantly (with countless concurrent processes), and optimize costs (with billing based on processor time and memory usage).

While serverless functions thrive independently in batch processing workloads, they’re often paired with or replaced by messages buses like Azure Service Bus to take advantage of the “Pub-Sub” communication model and more mature tooling.

With the introduction of Azure Event Grid, Azure Functions gain better integration, instrumentation, and tooling to connect services and bypass the need for separate message buses.
