Architecture Corner

In this episode, we explore what it truly means to be a software architect in rapidly growing companies. Drawing from five years of hands-on experience, we'll unpack:

• The misunderstood role that's neither team leader nor senior developer
• How architectural decisions impact development speed over time
• The three key responsibilities that define effective architecture work
• Practical approaches to bridging business needs with te...

Join us as we discuss why developing resilient applications matters in today's always-on digital world. We'll explore:

• Why scalability and availability alone aren't enough for modern applications
• The concept of resilience in microservice architectures
• Practical strategies for graceful degradation when dependencies fail
• How to incorporate failures into your design process
• Implementing circuit breakers to detect and handle...

Is AWS DynamoDB the right choice for your next project?

Join us as we discuss DynamoDB - Amazon's NoSQL database solution that handled a mind-boggling 146 million requests per second during the 2024 Prime Day.

In this episode, we'll explore:

• Why cloud architects are increasingly turning to DynamoDB for serverless and microservice architectures
• The impressive scalability and durability features that make DynamoDB a power...

Transactional Consistency in Event-Driven Applications: The DynamoDB Streams Approach

This episode will cover:

• The challenge of maintaining atomic operations in distributed event-driven applications
• Why traditional transaction support is missing in distributed environments
• A practical problem scenario: e-commerce order processing with failed event publishing
• The transactional outbox pattern as a solution for atomic persistence and e...

In this episode, we tackle the inevitable challenge of evolving event structures in Event Sourcing systems. We'll discuss practical strategies for maintaining system integrity while accommodating new business requirements.

Topics we'll cover include:

• Why events must evolve as your business requirements and domain model change
• When to modify existing events versus creating entirely new event types
• Implementing event versioni...

In this episode, part III of IV, we dive into advanced access patterns for Event Sourcing systems. Building on our previous discussions about retrieving individual entities, we'll explore how to effectively implement read models using the CQRS pattern to satisfy complex querying requirements.

We'll cover:

• Why basic entity retrieval isn't enough for real-world applications
• Creating optimized read models (projections) fr...

In this episode, we dive into an exploration of Event Sourcing, an architectural pattern that fundamentally changes how we think about application state.

Rather than directly storing the current state, Event Sourcing rebuilds it from a sequence of events.

We'll explore the key concepts that make this pattern work, including the critical distinction between state and events, and how the event store serves as the application'...
