Quarkus is the Opposite of Wildfly

An airhacks.fm conversation with Dimitris Andreadis (@dandreadis)
about: Amstrad CPC 484, but Commodore had better games, learning
BASIC driven by lack of games, hacking game loaders, C is the
favourite language, with C you have the full control, C is concise,
ISO DEE, writing ISO network layers in Ireland, writing reactive
code in 1994, beautiful C code, processing bibliographic data with
DSLs, maintaining passion and fun at indexdata.dk, enjoying the
time at navy, clueless mainframe operators, writing programs in
COBOL instead of queries, PDP 11 as simulator for naval training,
writing application servers in C++ for telecom, EJB-like components
in C++, Java UIs in 1998, Java should be good enough for writing
service provisoning platforms, accidental discovery of Java
Management Extension (JMX), first Java impression was not as good,
JBoss was a heavy JMX user, JBoss was always manageable because of
JMX, Rickard Öberg was a genious, dynamic kernel with dynamic
extensions, Marc Fleury started JBoss, JBoss 2 was a rewrite, JBoss
2 kernel was the base for project "Junction" renamed to Action
Streamer, JBoss became more interesting than the day job, core
JBoss developer since 2004, CORBA / CSIv2 skills were needed for
J2EE certification, transferring transactions and security context
with CORBA extensions, JBoss was the first J2EE certified server,
Dimitris was project lead for JBoss 4 and 5, later manager, now
responsible for Thorntail, Vertx and Quarkus, in JBoss CORBA
objects were dynamically generated, the paper: "The JBoss
Extensible Server" from brazilian professor, Thrift, gRPC and Co.
are CORBA, just reinvented, CORBA network layer is very efficient,
EJBs killed CORBA, JBoss unified the web container and EJB
container in a single JVM to prevent remote communication,
microservices are distributed, sometimes unnecessarily, EJBs and
WebContainers had to split into separate JVMs back then as well,
Quarkus is the exact opposite of WildFly, Quarkus and WildFly also
have different goals, the WildFly.next discussions at RedHat, Jason
Greene and Bob McWhirter had WildFly discussions, Emanuel proposed
a single runtime for everyone, the one base runtime for everyone
prototype, SubstrateVM produced the best native code, Hibernate on
Quarkus was a break-through, Quarkus is a collective,
interdisciplinary effort at RedHat, Quarkus started in spring 2018,
Quarkus pushes the Java EE deployment model further and the
optimisations are collateral, Quarkus looks and feels like Java EE
or MicroProfile, Quarkus does not require proprietary imports,
Quarkus went for native optimization, and optimized HotSpot JVM as
well, Quarkus build makes code less memory hungry at HotSpot,
Quarkus takes have of the memory with fast startup time, Quarkus
comes also with runtime improvements in HotSpot and native mode,
the idea for build-time optimizations started at WildFly, with
pre-computing the deployment model, Quarkus extension model allows
the integration of 3rd-party code for native compilation, Quarkus
development mode comes with scripting-like experience, Quarkus
FatJars aren't fat, nor self-contained, Quarkus runner-jars are
optimized for Docker and so clouds, Quarkus offers imerative and
reactive APIs, Netty, Vert.x and Undertow are unified inside
Quarkus, Panache ORM is an experiment, but could become a
MicroProfile or Jakarta EE standard, working with standards is
difficult, Quarkus pushes standards further, developers hack the
code first, then standard comes, writing Kubernetes operators with
Quarkus
