Notes

• In cloud, have both microservices and traditional web apps

Microservice

• Container (ex: docker) including UNIX kernel
• Executable Jar or Native Image (ex: Graal)
• Example microservice framework – Http Server, Http Java Integration, REST processing, JSON serialization, JSON parsing, validation, security, database integration, dependency injection, messaging, mail, health checks, tracing, fault tolerance, metrics, config, OpenAPI docs, GraphQL
• Microservice frameworks – Spring boot, quarkus, micronaut, open liberty

Spring Boot

• Http Server – Jetty, Tomcat or Underflow
• Http Java Integration – Jakarta Servlet
• REST processing – Jakarta RESTful Web Services or Spring MVC
• JSON serialization – Gson, Jackson or JSON Binding
• JSON parsing – Gson, Jackson or JSON Parsing
• validation – Jakarta Bean validation
• security – Spring security
• database integration – JPA and others
• dependency injection – Spring framework
• messaging – Jakarta messaging, kafka and others
• mail – spring java mail sender or jarkarta mail
• health checks – spring boot actuator
• tracing – spring cloud sleuth
• fault tolerance – spring cloud circuit breaker and spring cloud netflix
• metrics – micrometer
• config – spring boot config
• OpenAPI docs – Spring REST data
• GraphQL – Spring for GraphQL

Others

Did same for Quarkus, Payara Micro, Jarkarta EE. Didn’t transcribe deck

A lot of delegating to Jakarta and MicroProfile projects

MicroProfile

• Started in 2016

Jakarta projects

• Jakarta Interceptors – standard way of writing interceptors
• Platform – Jakarta enterprise beans, authorization, batch, connectors, mail, activation, messaging, web profile, core profile
• Optional (not fully supported) – Jakarta enterprise web services, xml binding, SOAP with attachments, XML web services
• Web profile – servlet, bean validator, persistence, authentication, web socket, CDI, mail, security, transactions, expression language, managed beans, concurrency, faces, standard tag libraries, server pages, enterprise beans light
• Core profile – interceptor, dependency injection, annotations
• Required for MicroProfile – Jakarta RESTful web services, JSON processing, JSON binding, CDI light
• CDI surpassing EJB
• New: Jakarta RPC, NoSQL, data
• Removed: Jakarta Management

Java EE Server

• War
• Jakarta Servlet, RESTful web services, JSON binding/parsing, bean validation, security, persistence, CDI, messaging, mail

My take

Wow. A lot has changed since I last worked on a web app. Learned a lot here although the talk was longer than my attention span; especially later in the day. It was a bit of an info dump but good for getting the lay of the land. And I need to do a lot of reading!
