Latency and the Art of Patience: Navigating AWS Lambda Invocation Modes

In the world of cloud-native computing, where milliseconds can draw the line between user satisfaction and digital abandonment, the invocation style of serverless functions can be more than just a technical decision—it’s a philosophical one. AWS Lambda, Amazon’s premier serverless compute service, provides two primary invocation types: synchronous and asynchronous. While both might appear as… Read More »

The Invisible Trap: Unraveling Recursive Invocation Loops in AWS Lambda

In the layered symphony of serverless computing, AWS Lambda often plays the role of a virtuoso. Its elegance lies in abstraction — the ability to forget infrastructure while executing precise functions at scale. But within this autonomy lies a paradoxical flaw that even seasoned architects sometimes underestimate: the recursive invocation loop. Far from being a… Read More »

Cut AWS Lambda Costs Effectively Using Event Filters

AWS Lambda is a serverless computing service that allows developers to run code without provisioning or managing servers. You pay only for the compute time consumed by your function invocations. While Lambda eliminates the need for infrastructure management, costs can rise quickly with frequent or unnecessary function triggers. Understanding how Lambda charges are calculated is… Read More »

Optimize AWS Lambda Costs Using Event Filtering Techniques

AWS Lambda has transformed how serverless applications are built by abstracting infrastructure concerns and enabling event-driven architectures. However, as serverless adoption grows, many developers face escalating costs from excessive Lambda function invocations triggered by unfiltered events. Each Lambda invocation incurs a charge, regardless of whether the event is pertinent or merely noise. This financial drain… Read More »

Fetching Configuration Parameters from AWS SSM Parameter Store via Lambda

Modern applications increasingly rely on serverless computing to achieve agility and scalability. However, a persistent challenge in this landscape is managing configuration data securely and consistently. Centralized configuration management becomes essential to ensure that application components retrieve the right parameters without compromising security or performance. AWS Systems Manager Parameter Store addresses this need by providing… Read More »
