ServerlessUmgebungen

ServerlessUmgebungen, often referred to as serverless computing, represents an execution model for cloud-native development where the cloud provider dynamically manages the allocation and provisioning of servers. Developers write and deploy code without needing to manage the underlying infrastructure. This means there are no servers to provision, patch, or manage. The cloud provider handles all server management aspects, including capacity provisioning, patching, and operating system maintenance.

The core concept of serverlessUmgebungen is that developers focus solely on writing application code, typically in the form of functions. These functions are event-driven, meaning they execute in response to specific triggers, such as an HTTP request, a database change, or a file upload. The cloud provider automatically scales the resources required to run the code based on demand. When the code is not running, no compute resources are consumed, and therefore no costs are incurred.

Key benefits of serverlessUmgebungen include reduced operational overhead, automatic scaling, and a pay-per-execution pricing model, which can lead to significant cost savings for applications with variable or infrequent workloads. However, challenges can include vendor lock-in, potential for cold starts (initial latency when a function hasn't been invoked recently), and limitations in debugging and monitoring compared to traditional server-based architectures. Popular examples of serverless platforms include Amazon Web Services Lambda, Azure Functions, and Google Cloud Functions.
