Practices for performance optimization come after we spent several months digging into serverless environments and optimizing how we behave in them. Along the way we've discovered a number of best practices that you can adopt in your own applications to maintain the highest possible performance. at some of the best practices we've discovered. Host your functions in the same region as your database Whenever you host an application or function that requires access to a traditional relational database you need to initiate a connection to that database. This takes time and introduces delays. you perform. Your goal is to keep time and latency to an absolute minimum. The best approach currently is to ensure that your application or feature is deployed in the same geographic region as the database server. The shorter the distance your request has to travel to.
Reach the database server, the faster the connection will be established. This is very important to keep in mind when deploying serverless applications because not doing so can have significant negative consequences. Failure to do so may affect the following The time it photo editing servies takes for an operation to complete the handshake, secure the connection to the database, and execute your query. All of these factors are activated during a cold start and therefore affect the impact that using a database with a cold start has on an application. While investigating the impact of this on cold starts we noticed awkwardly that we completed the first few tests using serverless functions in , and instances hosted in . We fixed this quickly and after that measurements clearly showed the huge impact this could have on database latency, both for creating connections and for any queries executed before and after. Using a database that is.
Not too close to your function will directly increase cold starts. duration but the same cost is also incurred when executing the query later during hot request processing. Run as much code as possible outside the handler Consider the following serverless function which in some cases allocates more memory to the virtual environment and during the initial startup of the function execution environment. The memory available to the function during subsequent calls to the hot function is actually guaranteed to be the configured value in the function's configuration and may be less than the value outside the function. Note If you're curious here.
