Functions In a serverless environment your functions can be reduced to zero. This allows you to minimize operational costs but also incurs technical costs. A new function must be instantiated when you have no available function instance to respond to a request. This is called a cold start. Watch for a detailed explanation of what a cold start is and how we can minimize cold start times when using it.Used Serverless Cold Start to Make Serverless Cold Starts 2x Faster. A slow cold start can give users a very 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 These functions are composed of 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 perfor photo editing servies mance 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 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 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 measurement.
