Structuring Java Applications CLI, monoliths, microservices and serverless by Adam Bien

PRESENTATION TITLE:
The One and Only Way to Structure Java Monoliths, Microservices ...and even Functions

DESCRIPTION:

In this CJUG session, I will create a Java service from scratch, run and test it locally, in container environments, and as AWS Lambda. Same code base, minimal code, no YAML, and the same APIs on different runtimes. I will focus on structure, maintainability, and the "no-dependencies" approach. Your questions are highly appreciated, and I will answer them in real time.

Speaker
Adam Bien
I'm (Adam Bien / @AdamBien) working as a a freelancing consultant with Java since JDK 1.0, with Servlets/EJB since 1.0, before the advent of J2EE in several large-scale applications and with JavaScript since 1995 on Netscape Navigator.

I am an architect and developer (with usually 20/80 distribution) in Java (SE / EE / Jakarta EE / MicroProfile) and Web (ES 6+, Web Components, Web Standards "no frameworks") projects. Often I'm starting as an architect and after a few days finding myself developing PoCs, performing code reviews, or helping the teams developing critical parts of the system.
In the recent years I helped many clients to migrate Java EE / Jakarta EE / MicroProfile applications to serverless architectures on AWS and Azure. Such projects often started as code- and architecture review and ended with a pragmatic cloud migration.

My clients sometimes ask me: "O.k., but what about the web frontend?" so I'm also helping companies to avoid migrations by using web standards such as ES 6, modern CSS, and Web Components for productive development of sustainable web applications. Sometimes we are migrating existing but "bloated" applications away from a framework to vanilla web standards.

I have written several books about JavaFX, J2EE, and Java EE, and I'm the author of Real World Java EE Patterns—Rethinking Best Practices and Real World Java EE Night Hacks—Dissecting the Business Tier. I'm writing books and articles during my travels and sometimes even unproductive meetings.

In my leisure, I participate in the JCP as an Expert Group member for the Java EE 6 and 7, EJB 3.X, JAX-RS, CDI, and JPA 2.X JSRs.
I am also a Java Champion, NetBeans Dream Team Founding Member, Oracle ACE Director, Sun :-) Certified Programmer, Sun Certified Java Architect, AWS Hero, AWS Certified Cloud Practitioner, AWS Certified Developer Associate, AWS Certified Solutions Architect Professional, AWS Certified SysOps Administrator Associate, AWS Certified Database - Specialty, Java Developer of the Year 2010, and attendees of my sessions chose me as JavaOne 2009 and double 2011, 2012, 2014 and triple 2013 Rock Star.

I'm speaking regularly at conferences, but I'm neither a professional speaker nor a writer. I'm just really enjoying to write code and kill the bloat. ...and Java is perfect for that.

Great talk! Question: What is your experience an incident of a missbehaving lambda with high traffic, where a particular instance migth stay provisioned for up to 2 hours if I remember correctly?
