Confused about Azure messaging? In this episode, Azure Architect Bhanu Prakash explains Event Grid vs Event Hub vs Service Bus, helping developers and architects choose the right Azure service for event-driven and serverless systems.

Learn when to use Event Grid for events, Event Hubs for telemetry and streaming, and Service Bus for reliable enterprise messaging — with real-world Azure architecture examples in under 5 minutes.

Event Grid, Event Hub, and Service Bus are some of the most misunderstood services in Azure — and treating them as interchangeable is a common reason event-driven systems fail in production.

In this short, focused episode, Bhanu Prakash (Azure Architect & Developer Advocate) explains Azure messaging the right way, using a clear mental model that helps developers and architects confidently choose between Event Grid, Event Hubs, and Service Bus.

You’ll learn:
• The real difference between events vs messages — and why it matters
• When to use Event Grid for reactive notifications and integrations
• When Event Hubs is the right choice for telemetry and streaming data
• When Service Bus is essential for reliable, ordered, enterprise messaging
• How throughput, ordering, retries, and guarantees affect architecture decisions

This episode cuts through Azure documentation noise and focuses on real-world design trade-offs, not demos or theory. Perfect if you’re building APIs, serverless systems, IoT pipelines, or event-driven architectures on Azure.

If you’ve ever dealt with lost messages, broken ordering, scaling issues, or the wrong messaging choice slowing your system down — this 5-minute episode will reset how you think about Azure messaging.

00:06:37 – 💰 #8 Decision Framework: When to Code, When to ClickAzure Logic Apps and Azure Functions are both serverless—but once you step into production, they behave like completely different worlds. If you’ve ever wondered which one to choose for APIs, integrations, automation, or event-driven workloads, this episode is your deep-clarity guide. In just eight minutes, Bhanu (Azure Architect & Developer Advocate) breaks down the real-world differences no documentation page will tell you.

This episode goes far beyond “low-code vs code-first.” Instead, it exposes the subtle architectural trade-offs that impact cost, performance, observability, governance, and operational reliability. You’ll learn how Logic Apps can become expensive from connector calls and loops, why Azure Functions offer more control but demand stronger engineering discipline, and where both services shine when used together.

🧠 What You’ll Learn

• The true differences between Logic Apps and Functions in real production systems
• How consumption-based billing works behind the scenes—and how to avoid surprise invoices
• Why Logic Apps offer powerful visual debugging, while Functions give you full code-level insights
• When workflow automation becomes spaghetti in Logic Apps—and when Function orchestration explodes in complexity
• The networking, identity, and security gaps developers overlook
• The CI/CD challenges of Logic Apps compared to the smooth pipelines of Functions
• A practical, reusable decision framework for choosing the right serverless tool

🚀 Who This Episode Is For

• Developers building APIs, event processors, or integration workflows
• Architects designing scalable, secure cloud backends
• DevOps engineers focused on observability, deployment automation, and cost control
• Technical leads evaluating serverless choices for reliable enterprise systems

If you’ve ever dealt with connector-heavy bills, messy workflow dependencies, retry storms in Functions, or deployment blockers in Logic Apps, this episode will give you clarity and confidence.

🔎 Why This Comparison Matters

Both services promise serverless simplicity, but choosing the wrong one can:
• Inflate monthly costs 💸
• Slow down release cycles 🐢
• Break monitoring and troubleshooting workflows 🔍
• Complicate networking and identity design 🔐
• Misalign with your DevOps strategy 🚧

By the end, you’ll know exactly when to choose code (Functions), when to choose clicks (Logic Apps), and when a hybrid approach gives you the best architectural balance.

👩‍💻 For Developers & Architects

This breakdown gives you practical design guidance:
• When to use Durable Functions for long-running workflows
• How to build reliable, secure Logic Apps
• Designing event-driven architectures that scale predictably
• Balancing low-code speed with code-first control

If you build or maintain Azure serverless systems, this is your concise masterclass.

Are your Azure Functions silently failing, scaling unpredictably, or breaking due to hidden configuration issues?
This in-depth podcast walks developers and cloud architects through the 12 most dangerous and commonly overlooked Azure Functions pitfalls—specifically in Triggers, Bindings, Scaling, Message Processing, Observability, and Serverless Architecture.

Designed for real-world production environments, this session reveals how small mistakes in bindings, host.json, schema design, Event Hub partitions, Service Bus sessions, and Cosmos DB leases can cause massive reliability issues in distributed systems. Whether you're building event-driven microservices, data ingestion pipelines, automation workflows, or mission-critical enterprise serverless apps, this podcast brings clarity to what really goes wrong behind the scenes in Azure Functions and how to fix it.

• Wrong Binding Types — why Functions fail silently when your binding direction or type mismatches the trigger
• Schema Coupling Mistakes — how tightly coupled payload shapes break serverless workflows
• Service Bus Poison Message Pitfalls — preventing dead-letter loops that halt entire pipelines
• Over-Reliance on Bindings — when too much magic hides critical operational control
• Misconfigured host.json — scaling failures caused by wrong batch sizes, concurrency, or prefetch
• Missing Service Bus Sessions — ordering, locking, and workflow execution breaks
• Event Hub Partition Misalignment — Why your functions under-scale or over-load partitions
• Cosmos DB Change Feed Lease Issues — how bad lease configuration stops change feed processing
• Authentication Pitfalls — MSI vs connection strings vs Azure AD misalignment
• Binding Expression Failures — runtime surprises caused by naming mismatches or invalid patterns
• Durability Assumptions — when functions are not durable the way you believe they are
• Monitoring Blind Spots — hidden errors in Application Insights that developers never notice

Each pitfall is explained with clear examples, production impact, and the exact fix.

This session is crafted for:

• Azure Developers building Functions in C#, .NET, Python, or Node

• Cloud Architects designing event-driven or serverless systems

• Solution Leads responsible for reliability, scaling, and performance

• Engineers preparing for AZ-204 or AZ-305

• Anyone managing Azure Event Hub, Service Bus, Cosmos DB, or Storage triggers at scale

  
  

Azure Functions appear simple, but production failures are almost never caused by code—they stem from hidden platform behaviors, misconfigured bindings, and incorrect assumptions about how serverless triggers operate.
This episode demystifies those layers and gives you the operational clarity to run Functions reliably at scale.

If you're building enterprise-grade serverless applications, this is a must-listen.
