AWS Lambda Managed Instances lets you run Lambda functions on EC2 instances while keeping the serverless experience. This feature provides access to specialized compute options and cost savings for steady workloads without the hassle of managing infrastructure. You can configure capacity providers to optimize for your specific needs.

AWS Lambda now officially supports Rust for building serverless applications. The article explains how to set up and deploy Rust-based Lambda functions using Cargo Lambda and the AWS Cloud Development Kit (CDK). It covers prerequisites, function creation, testing, and deployment steps.

AWS introduced Durable Functions for Lambda, allowing developers to create multi-step applications directly in their code. These functions can track progress, handle retries, and pause execution for up to a year without incurring costs. This feature streamlines state management and simplifies complex workflows.

AWS has introduced a new feature that allows for the deployment of AWS Lambda functions directly through GitHub Actions, simplifying the CI/CD process with a declarative YAML configuration. This improvement eliminates the need for manual packaging and configuration steps, enhancing developer experience and security through seamless IAM integration. Users can easily set up a workflow to automatically deploy their functions with minimal effort.

AWS Lambda offers best practices for handling billions of asynchronous invocations, emphasizing the importance of scalability and reliability in serverless applications. The article outlines techniques such as simple queueing, consistent hashing, and shuffle-sharding to mitigate issues like noisy neighbors and traffic spikes, ensuring efficient load distribution and fault tolerance. Additionally, it highlights proactive monitoring and resilience strategies to maintain service quality during high-demand periods.
