How to chose whether we deploy a jar or a war in Spring-Boot application?

Question

What I understand is we can deploy a spring-boot application as a jar and as a war as well. What I don't understand is when should we go with a jar and a war ? I am talking about spring-boot web apps.

Answer 1

Both ways are equivalent technological wise.

JAR is a preferable way of deploying spring boot application, so consider it it as a first bet.

WAR is required if you already have java web servers (tomcats) managed by people who don't want/need to adopt a new / another way of deployment. Usually this happens in large organizations or organizations with a dedicated IT / adminstration/ops department (many names exist for this), but essentially these are people who are responsible for deployment of the application.
