Service Discovery, J2EE to Quarkus, AWS Lambda, System Testing, CI/CD and JFRs--132nd airhacks.tv 📎

The 2025.03 / 132nd edition of airhacks.tv with the following topics:
" J2EE to Quarkus migration can save around 50% memory for on-premise deployments, EJBs are straightforward to migrate but MDBs with two-phase commit are challenging, Change Data Capture like Debezium is an elegant solution for transaction handling, Running JFR all the time in production is a best practice for on-premise deployments, CryoStat provides visualization for JFR events in OpenShift, Quarkus binary executables work well for AWS Lambda but require managing your own runtime, Using AWS-managed Corretto runtime is advantageous for security patching, Application Load Balancer can route to both Fargate and Lambda behind the same URI, Function URL is the cheapest way to run Lambda but HTTP API Gateway provides nicer URIs, Monolithic applications are still valuable when well-structured, Modern Java with records can make JDBC more appealing than ORMs for complex queries, Cloud provider migration is less about Java code and more about mapping equivalent services, System testing should be done by deploying applications to production-like environments and testing them functionally."

Questions and topics for the 2025.03 / 132nd edition of airhacks.tv with the following topics:
  1. How should I handle MDBs (Message-Driven Beans) and two-phase commits when migrating Java EE applications to Quarkus while minimizing code rewrites?

  3. What are the best practices for effectively using Java Flight Recording in an OpenShift cluster environment?
  4. Is deploying a Quarkus binary executable as a custom runtime for AWS Lambda better than using a container image?
  5. How can a Lambda function be used to offload work from Kubernetes/locally hosted Quarkus services during peak demand?
  6. 100 episodes back in time:
    Monolithic Java EE?, UI (servlet,JSP) vs. EJB / CDI authentication, JDBC vs. ORMs, implementing a WebService on a JVM vs. on an application server, Docker host resolution and staging, Launching docker images in production, Multiple server instances vs. multiple docker containers, Solr vs. ElasticSearch, Docker RAM limits vs. JVM maxheap, How to learn Java EE and Java, The Purpose of ejb-jar.xml, gRPC and microservices, Handling security patches with Docker, UriInfo with proxies, Approaches to secure JAX-RS services
