Developers in serverless and edge environments. One of the major issues faced when building data-driven applications in a server environment is the use of cold starts. The Dreaded Cold Start One of the most common performance issues when working in a serverless environment is long cold starts. But what is a cold start? Unfortunately this term has a lot of ambiguity and is often misunderstood. in which a serverless function is instantiated and its execution occurs when the function handles its first request. While this is a basic technical explanation there are some specific things to remember about cold starts.
  
They are essentially unavoidable after the function is still not ready to handle the request. The virtual environment is ready with all the code in place but no code has yet been processed by the ru photo editing servies ntime. The application must be initialized as described in the next step before calling the handler. Note that the launch details of these functions are not configurable and are handled by your cloud provider. You don't have much say in how it works. Step 1: Start the application Typically application code exists in two different scopes Code outside the handler function Code within the handler function In this step your cloud provider will execute the code outside the handler.



The code inside the handler will be executed in the next step. When running the above function the following is logged so you can see how the outside is executing even before the actual content is logged. If there are any import constructor calls or other code it will also be executed at this time. This line will no longer be logged when a warm start request is made to the function. Code outside the handler is only executed once during a cold start. The third step is to execute the application code to execute the processing function in the last part of the startup process. It receives the incoming request i.e. request header body etc and runs the logic you have implemented. The log from the previous step continues so that the cold start of .
