Serverless AWS Applications with Java

In case you need an invoice with VAT, please use: https://airhacks.live registration form.

Managing and provisioning various cloud services is as complex as writing application Java code. In contrast to application code, the cloud infrastructure is highly reusable.

This workshop is a continuous review of ready-to-use templates, examples, and patterns of serverless applications on Amazon Web Services, focusing on serverless. We will use Infrastructure as Java Code: AWS Cloud Development Kit (CDK v2) for Java and use Maven repositories to quickly build and share the code.

In this workshop, I won't implement each application from scratch, rather than walk through already prepared ready-to-use examples and templates reflecting common patterns and adjust them to more specific use cases.

All changes, attendees' requests, and suggestions will be committed to a git repository in real-time.

Topics:

After a a short introduction to AWS basics (VPC, IAM, accounts, storage and organizations), we will cover the following templates and use cases:

Continuous deployment with AWS Cloud Development Kit (CDK) v2

A reusable AWS ECS Fargate construct with Quarkus, Docker image creation and push

MicroProfile (e.g. Quarkus) microservices on ECS Fargate with private DNS names with Route 53

ECS Fargate application behind an Application Load Balancer with end to end SSL encryption and automated certificate handling

ECS Fargate application on Quarkus accessing Aurora DB for PostgreSQL with secrets

Scheduled / cron jobs for ECS Fargate and Lambda

Scheduled tasks with ECS Fargate

Running microservices and AWS Lambdas in isolated VPCs

MicroProfile / AWS Lambda application accessing Aurora DB via JDBC

Using serverless, AWS managed Kafka with MicroProfile applications

Metrics and alerts for MicroProfile applications with CloudWatch

Using JWT, OIDC with MicroProfile applications and AWS Cognito

Automated provisioning of VPN and Bastion hosts for debugging

Automated DNS and SSL certificates handling

Native images with GraalVM on AWS

featuring: Quarkus, Helidon, Micronaut and plain Java SE

The agenda is based on questions from projects, conferences, workshops and is still in progress

In this advanced workshop I will discuss and implement cloud native Java / MicroProfile applications in serverless AWS cloud. As a reference, you will get a GIT repository with all snippets and solutions, as well as prepared sample applications.
