Serverless computing has rapidly become a go-to solution for developers seeking scalability and flexibility without the hassle of managing server infrastructure. It offers a paradigm where developers can focus on writing code, leaving the scalability and management of infrastructure to the cloud provider. AWS Lambda, one of the most popular serverless platforms, allows you to run code in response to events without provisioning or managing servers. This makes it an ideal choice for building event-driven applications that need to scale seamlessly.
In this guide, we’ll walk through how to leverage .NET Core to build and deploy serverless functions to AWS Lambda. If you’re new to AWS Lambda, it’s important to understand that this platform supports multiple programming languages, and .NET Core is one of the officially supported runtimes. Before we dive into the code, make sure you have Visual Studio 2019 installed on your system, as well as the AWS Toolkit for Visual Studio 2019, which provides templates to streamline the development process.
Additionally, to interact with AWS services, an AWS account is required. If you don’t have one yet, you can easily create a free AWS account. Once your account is set up, you’ll be ready to start deploying serverless functions to AWS Lambda. These functions can be triggered by events from other AWS services, like changes to files in S3 or new data arriving in a DynamoDB table, enabling automation and real-time processing in your applications.
The AWS Toolkit for Visual Studio 2019 provides specific project templates designed to simplify the creation of .NET Core-based AWS Lambda functions. These templates come with predefined settings and code structures to help you quickly get started with Lambda. By using these templates, you can reduce the complexity of setting up a Lambda project, allowing you to focus more on writing the logic and handling the events that trigger your functions. In the next sections, we’ll explore how to create these Lambda functions step by step.
