Join Ben Evans to learn everything you need to know to successfully upgrade from Java 8 to Java 11 or 17!
Java 17 is the current long-term support (LTS) release of one of the world’s most popular programming languages. However, over 40% of applications still report running on Java 8 (released in 2014), two LTS releases behind the current version.
Applications that have migrated to Java 11 or 17 will typically experience better performance (often significantly) and smaller resource footprint than when under running Java 8. Upgrading to versions after Java 8 also brings in much better support for cloud and container environments. These improvements often provide a great opportunity to save money by reducing cloud / infrastructure spend.
Join Ben Evans to learn what you need to know to successfully upgrade both your teams and existing applications from Java 8 to Java 11 or 17.
