Lambda performance tuning | Serverless Office Hours

Learn best practices and guidance opportunities to optimize your serverless applications built with AWS Lambda. Solutions Architects, Luca Mezzalira and Matt Diamond, join Julian Wood to discuss optimizations in the function configuration and within your function code. Find out how you can best measure and tune your function’s performance by configuring memory to get the right application performance. Discover best practices for initialization logic and reuse to enable fast startup and fast processing of your functions. We are also available to answer any of your serverless questions.
