The AWS SDK for Java 2.0 includes a number of new features and performance improvements. Using real code examples, we'll build a serverless application that makes use of the SDKs new HTTP2-based event-streaming APIs and deploy it using AWS Java tooling introduced in 2018. You'll learn what's new in 2.0 and the benefits of upgrading, as well as how to take advantage of new tooling in AWS's already rich Java ecosystem.
