What is the best practices to increases the performance of the lambdas? I mean could someone give me tips to improve AWS Lambda performance? I have to manager too many data of some database, for example, how can I improve the speed of processing?

This is large topic with a broad set of answers.

There are several ways to improve the performance of AWS Lambda functions:

  1. Optimize code: One of the easiest ways to improve the performance of AWS Lambda functions is to optimize the code. You can use best practices for coding and optimize the algorithms used in your code to reduce the time and resources required for processing.
  2. Reduce package size: The size of the package uploaded to AWS Lambda can impact the function’s performance. Try to reduce the package size by using smaller libraries, minimizing dependencies, and avoiding unnecessary files.
  3. Use appropriate memory size: The amount of memory allocated to an AWS Lambda function can affect its performance. Increase the memory allocated to the function if it is running slowly.
  4. Use AWS services: AWS provides various services that can help improve the performance of Lambda functions. For example, if you’re managing a database, consider using Amazon RDS or Amazon DynamoDB to improve the speed of processing.
  5. Use caching: Use caching mechanisms to reduce the number of times data needs to be fetched from a database or external source. AWS provides services like Amazon ElastiCache and Amazon CloudFront that can be used for caching.
  6. Parallelize processing: If your code is processing large amounts of data, consider parallelizing the processing to improve performance. You can use AWS services like AWS Step Functions and AWS Batch to implement parallel processing.
  7. Monitor and optimize: Finally, monitor the performance of your Lambda functions using AWS CloudWatch, and use the data to optimize your code and infrastructure for better performance.
