And join our community channel to discuss how you can make a difference in your app development journey. We look forward to hearing from you Announcements Data Platform Don’t miss the next article Best Practices for Accelerating Serverless Applications Sabin Adams Sabin Dev Fast performance of applications is critical to delivering a great user experience In this article we will learn Pitfalls and best practices for optimizing cold start and handler performance in serverless applications. Best Practices Catalog for Accelerating Serverless Applications Introducing the Performance Pitfalls of Serverless Functions Best Practices for Performance Optimization Host your functions in the same region as your database Run as much code as possible outside of handlers Your functions Keep it as simple as possible Don't do more work than necessary Pre-configure concurrency Conclusion Introduction The serverless deployment paradigm with functions-as-a-service enables developers to easily deploy their applications in a scalable and cost-effective way.
However, this convenience photo editing servies and flexibility also comes with a set of complexities that need to be noted. In early deployment models using long-running servers, the execution environment is always available as long as the server is up and running. This enables your application to respond to incoming requests immediately. The new serverless paradigm requires us as developers to find ways to ensure your functionality is available and responds to requests as quickly as possible. Performance Pitfalls of Serverless 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. Read our recent article How.
We Used Serverless Cold Start to Make Serverless 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 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 This knowledge can be used to improve the performance of functions by moving code out of the scope of the handler. This ensures that code outside the handler is executed when the environment has more resources availableFor.
