AWS Lambda is a service that lets you run back-end code without the need to provision or manage servers. AWS Lambda takes care of scaling and high availability. The cost directly depends on how often and how long your code executes.

You will find examples of how to create and deploy AWS Lambda functions in different languages.

As part of the Serverless movement, AWS recently announced C# support for AWS Lambda functions. In this article, I will show you how to develop, install and call a simple C# AWS Lambda Function using Visual Studio 2015.

Before you start this example, first go to the Remarks section of this document and make sure you have all of the required components installed.

Lambda developers will handle issues that requires the use of other AWS resources. This topic focuses on S3 (Simple Storage Service) which will commonly be used for storing static files and other configurations. This documentation will consider using AWS-SDK in lambda, accessing files in S3 from Lambda and triggering Lambda functions when an S3 event gets fired

This documentation section focuses on developing against the Amazon Web Services (AWS) Simple Storage Service (S3). S3 is truly a simple service to interact with. You create S3 "buckets" which can contain zero or more "objects." Once you create a bucket, you can upload files or arbitrary data into the S3 bucket as an "object." You reference S3 objects, inside of a bucket, by the object's "key" (name).

Amazon Rekognition is a service that makes it easy to add image analysis to your applications. With Rekognition, you can detect objects, scenes, and faces in images. You can also search and compare faces. Rekognition’s API enables you to quickly add sophisticated deep learning-based visual search and image classification to your applications.

Upload File to AWS s3 bucket using spring rest API.
