The Coffee Break Statement: Overweight J2EE Application Servers

The Coffee Break Question:

Application servers offer everything the same, but what about resource consumption?

The Coffee Break Content:

J2EE application servers that have been developed over the years have evolved into everything that is possible. What does this mean for resource consumption and are there alternatives?

Our statement today deals with a small comparison between different J2EE server approaches and one of it’s most popular alternatives Spring Boot.

Setup:

• Dell E6320 from 2011 running Ubuntu Linux
• Hello-World REST application based on Eclipse Microprofile

Result:

There are significant differences between the products in terms of startup time, memory and disc space consumption.

The Coffee Break Statement:

In addition to Blueprint and personal experience, it is worth taking a look at modern products and the exact requirements - choose your destiny :-)

How could you keep going?

Have you ever heard about serverless architecture?
