No. Servlet containers are still the foundation of most Java web apps.
Still dominant: Tomcat, Jetty and Undertow power Spring Boot, Jakarta EE and many enterprise systems.
What changed: they’re now usually embedded in the app (a single runnable JAR) instead of deployed as WAR files to a standalone server.
Standards continue: the Servlet spec lives on as Jakarta Servlet (jakarta.* namespace).
Alternatives growing: Netty-based reactive stacks (WebFlux, Vert.x), and Quarkus/Micronaut for fast-start cloud and native builds. These complement containers rather than replace them.
Improving Scala involves navigating the delicate balance of its dual nature as both an object-oriented (OO) and a functional programming (FP) language. Over the years, the language creator Martin Odersky, compiler teams, and the community have channeled these enhancements through the official Scala Improvement Process (SIP). The primary areas where Scala can be improved, based on community consensus, technical bottlenecks, and official development roadmaps, include
Both Python and Scala are excellent choices for learning Apache Spark, but the right choice depends heavily on your background and your career goals. If you already know one of these languages, start with that language. If you are completely new to both, Python (via PySpark) is generally the best language for beginners to learn Spark, while Scala is better if you want to focus heavily on core data engineering.
