Those who don't know the history of the past probably don't know why I'm so enthusiastic about Spring Boot. lol I'm a developer, but I've suffered a lot from infrastructure in my work, so I've studied the cloud and recently Kubernetes... I think that Spring Boot will be more impressive than traditional web services when it's distributed as a microservice. If you develop at the speed of light and show it, I think the customers will be very impressed. lol. I signed up for the lecture after looking at the Spring Boot 3. major manual, but I like it because I feel like I've only listened to the essentials~ Those who want to get on the fast track, listen quickly~ I finished it in 3 days~ Thank you.
