Are Java Application Servers Dead?

Posted by Alexius Dionysius Diakogiannis on in Application Servers 1 Comment

In the past, application servers were essential for running Java applications. They provided a number of features that were necessary for complex applications, such as:

  • Dependency management
  • Transaction management
  • Security
  • Caching
  • Messaging

However, with the rise of microservices, many developers are moving away from application servers.

As a result, many developers believe that application servers are no longer necessary for microservices. However, there are still a number of reasons why application servers can be beneficial for Java applications, even in a microservices architecture.

What are we going to do with this big heap of menhirs? The Importance of Evaluating Architecture Trends Within the Context of Your Business

The story: Caesar has sent his top economist to Asterix’s village with a plan to get the Gauls to fight each other instead of the Romans. The economist starts buying menhirs from Obelix. Obelix becomes snooty, money-driven, and unpopular. But now the Romans have a different problem and the question arises:

What are we going to do with this big heap of menhirs?

In today’s fast-paced digital world, architecture trends can be tempting. However, following them dogmatically can be detrimental to your business in the long run. Instead, it’s crucial to evaluate architecture trends within the context of your unique needs and digital transformation goals.

A recent example of this is Amazon Prime Video’s live stream monitoring service. The team originally used a distributed microservices architecture, which caused overhead and was costly. Instead of sticking to their original approach, they made the bold decision to combine their microservices into a monolith and scale it. The result was a 90% reduction in architecture costs.

I have created a video and I am showing how to place your java application to a docker container BUT in addition I am showing you how to build the application in the container without needing java runtime in the host machine.

Reposted in my medium blog here 

It has been a while but as per a friend requested I am going to show you how to deploy a Quarkus microservice behind an Nginx reverse proxy using docker.

What are we going to do…

I am going to install docker and docker-compose on a centos 8 host and I am going to deploy a docker container that will expose Nginx on ports 80 and 443 and a microservice using Quarkus. The same technique can be used with ANY java microservices framework like microprofile, Springboot etc because in the end what you will do is run a simple jar file (java is magic right?).

Let’s start…

I am going to skip the installation details for docker and docker-compose. In case you haven’t heard of docker-compose have look here https://gabrieltanner.org/blog/docker-compose and you’ll love it. It automates your container deployments and it just rocks! Continue reading “Deploying a Quarkus or any java based microservice behind an Nginx reverse proxy with ssl using docker” →
