The following measures to improve startup performance include only the code your function actually needs to do its job. Don't use libraries and frameworks that load a lot of unnecessary stuff. code that needs to be interpreted, the simpler the dependency tree will be and the faster the request processing will be. The sooner. Don't do more work than needed. Any value calculations or expensive operations that may be reused each time the function is called should be cached as variables outside the handler scope. Doing this avoids performing these expensive operations every time the function is called. Consider a situation where the values stored in the database do not change frequently such as configurable redirects. Although this code works but the query to find the redirects is run every time the function is called.

This is not ideal as it req photo editing servies uires accessing the database to find the value you already found during the last call. A better way to write it is to first check the cached value outside the handler. If not found then run the query and store the results for next time The query will now only run the first time the function is called. Any subsequent calls will use the cached value. One final thing to consider is using provisioned concurrency to keep things warm if you use them. According to the documentation note that provisioning concurrency initializes the requested number of execution environments so that they are ready to respond immediately to function calls. Please note that configuring.



Provisioned concurrency will incur charges to your account. This allows you to maintain a specified number of available execution environments that can respond to requests without cold-starting. While this sounds great, there are some important things to remember that using provisioned concurrency will incur additional costs. Your application will never scale down. These are important considerations as the added cost may be for your specific scenario. not worth it. Before taking this step we recommend that you look at the value it brings to your application and consider whether the added cost makes sense. Conclusion In this article we looked at some of the best practices we.
