The foundation of Application Resiliency is often found in the application code where Fault Tolerance is baked into the application at the time of designing and coding….

This presentation starts with building resiliency ground-up by baking the basic crucial patterns into the application. Resiliency4j provides the out of the box integration with Spring Boot, a defacto standard micro-service framework.

The patterns discussed include:

• Rate Limiter
• Retry
• Bulkhead
• Circuit Breaker
• Timeouts

Three evolutionary ecosystems work well together: Java, Containers, and Kubernetes. Past versions of Java were never designed to be "container aware." This has led some to stray from the JVM to consider other shiny languages for Containers.

But wait, let’s discover what Java 9, 10, 11, 12, 13 (…) has done to get our applications into efficiently distilled containers that pack nicely into Kubernetes.

In this presentation, Java developers will learn all about the broad support AWS provides to develop, build, and deploy Java applications on AWS. Services covered:

• AWS Tools & SDKs
• Codestar
• Lambda
• AWS Fargate
• Amazon Corretto

There will be a demo on how to quickly get a Spring Boot application up and running within Fargate (a serverless container offering from AWS) using the Cloud Development Kit.

The Cloud Development Kit (CDK) is a new project aimed at easily creating Infrastructure as Code. It allows you to express AWS infrastructure in programming languages such as Java or TypeScript. This allows you to write logic such as loops and inheritance that enables developers to easily construct sophisticated AWS environments using the full power of Java to specify and materialize an infrastructure, including base provisioning and beyond.
