Storage capacity, access rights and timeout settings can be configured more specifically.<\/p>\n\n\n\n<p>As the allotted storage space of a Lambda function is increased, the capacity of the CPU and the network increases as well. The optimal ratio between execution time and costs should be determined by way of benchmarking.<\/p>\n\n\n\n<p>A function should not call up another synchronous function. The wait causes unnecessary costs and increased coupling. Instead, you should use asynchronous processing, e.g. with message queues.<\/p>\n\n\n\n<p>The deployment package of each function should be as small as possible. Large external libraries are to be avoided. This improves the cold start time. Recurring initializations of dependencies should be executed outside of the handler function so that they have to be executed only once upon the cold start. It is advisable to define operative parameters by means of a function\u2019s environment variables. This improves the reusability.<\/p>\n\n\n\n<p>The rights to access other cloud resources should be defined individually for each function and as restrictively as possible. Stateful database connections are to be avoided. Instead, you should use service APIs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>With the serverless model, application components such as databases or data processing components are provided and operated, automated and demand-based, by the cloud service provider.
