In this session, we'll explore diverse strategies to notably trim down the resource footprint of typical Spring Boot applications. This includes harnessing Spring AOT for standard Spring applications, compiling Spring Boot apps into native images (leveraging GraalVM), and deploying CRaC for instantaneous startup (especially beneficial for scale-to-zero scenarios). We'll conduct a side-by-side comparison of these approaches, delve into the merits and demerits of each technology, and present tangible metrics from real-world applications. Our aim is to provide the audience with insights into the substantial enhancements achievable by employing these cutting-edge technologies.
