To Make Serverless Cold Starts 2x Faster. bad experience and ultimately degrade their experience with the product. This is the problem. In addition to the cold start problem, the performance of the actual handler function is also very important. Serverless applications typically consist of many small independent functions that interact with each other through protocols such as event bus queues. The intercommunication between various functions creates a dependency chain for each request. If one of the functions is very slow it will affect the rest of the chain. So handler performance is the issue. Best 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. In the rest of this article we'll look 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 photo editing servies relational database you need to initiate a connection to that database. This takes time and introduces delays. The same goes for any query 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 time it takes to complete the handshake, protect the connection to the database.
And execute your query. All of these factors are activated during a cold start and therefore affect the impact of using a database with a cold start on your application. While studying 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 very 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.
