Managing concurrency in serverless applications can significantly impact your system's performance and reliability. When your Lambda functions start overwhelming downstream services or hitting execution limits, you need practical solutions that don't require complex custom code.

We will cover:

• The core challenges of concurrency in asynchronous serverless executions
• Traditional approaches to managing Lambda concurrency and their limitations
• How reserved concurrency works and its potential drawbacks
• AWS's Maximum Concurrency feature for SQS event sources
• The difference between reserved and maximum concurrency settings
• Real-world scenarios where concurrency control prevents system overload
• Best practices for implementing concurrency controls without losing messages

Is EDA really the decoupling solution we think it is?

Join us as we dive into the nuanced world of Event-Driven Architecture with insights from Mario Bittencourt's analysis on coupling challenges.

We'll explore:

• The promise versus reality of decoupling in distributed systems
• Three distinct types of coupling that impact your architecture decisions
• Why "zero coupling" might be an impossible dream
• Real-world challenges you'll face: out-of-order events, message duplication, and debugging complexity
