Effective logging is an important part of an observability strategy when building serverless applications using AWS Lambda. Lambda automatically captures and sends logs to Amazon CloudWatch Logs. This allows you to focus on building application logic rather than setting up logging infrastructure and allows operators to troubleshoot failures and performance issues more easily. On May […]

In this post, you learn how to use AWS serverless technologies, such as Amazon EventBridge and AWS Lambda, to build an integration between Quick Service Restaurants (QSRs) and online ordering and food delivery aggregators. These aggregators have taken off as an option to QSRs to expand their consumer base, enabling them with delivery options to help grow their businesses.

Effective August 1, 2025, AWS will standardize billing for the initialization (INIT) phase across all AWS Lambda function configurations. This change specifically affects on-demand invocations of Lambda functions packaged as ZIP files that use managed runtimes, for which the INIT phase duration was previously unbilled. This update standardizes billing of the INIT phase across all runtime types, deployment packages, and invocation modes. In this post, we discuss the Lambda Function Lifecycle and upcoming changes to INIT phase billing. You will learn what happens in the INIT phase and when it occurs, how to monitor your INIT phase duration, and strategies to optimize this phase and minimize costs.

I show how traditional web-server applications compare with their serverless counterparts. I show how the infrastructure is managed for you in serverless, and how code for serverless developers in primarily focused on business logic.

AWS Lambda first announced support for Amazon SQS standard queues as an event source in April 2018. This allows builders to develop serverless applications using queues to directly invoke Lambda functions. Today, we have expanded this feature to include SQS FIFO queues. This makes it easier to create serverless applications using queues where the order […]
