Welcome back to TechTalks with Manoj — the show where we break down what’s really driving modern cloud systems — not just what’s trending in analyst reports or flashy keynote slides.

In today’s episode, we’re diving deep into a service that’s quietly become the nervous system of reactive, event-driven architectures on Azure: Azure Event Grid.

We’re not talking surface-level triggers here. We’re talking about real-time messaging at scale — systems that respond instantly when a file lands in storage, when a VM gets deployed, or when an IoT device sends a signal from the field.

So if you've ever built a system with polling loops, brittle webhooks, or services that quietly fail when nobody’s watching — buckle up.

Here’s what we’re unpacking today:

* Why polling is dead, and push-based events are the future

* The difference between topics, domains, and subscriptions — and why it matters for scale

* How Azure Event Grid compares to other message brokers like Service Bus and Kafka

* Event filtering, schema evolution, and routing without writing a thousand lines of glue code

* Real-world use cases for serverless, automation, and IoT — and where Event Grid fits

* Architect-level cost tips, reliability patterns, and how to avoid silent failures

* The tier battle: Basic vs. Standard — and how to choose the right one without overpaying

* And how to turn Azure Functions into your anti-corruption layer for clean, secure, and validated event flows

Whether you're building microservices, automating ops, or just tired of bolting together brittle workflows — this episode will give you the clarity to build systems that respond, scale, and stay clean under pressure.

Let’s get into it.
