World is full of RESTful services. Many of them are written using hugely popular Spring Web @Controller programming model. Yet a lot of them still run on managed infrastructure. But it is changing and it is finally possible to deploy and run these services without application code changes in a scale to zero fashion using platforms such as AWS Lambda, Azure Functions etc, benefiting also from an attractive “pay as you use” billing model and without having to manage servers or even containers. In this hands on session Oleg will discuss and demonstrate how an existing Spring Web application can be deployed and execute on these serverless platforms.
