Is Jira a Monothic application ? I think its not Microservice architecture ?

[Rahul Jodavula]

For example , its deployed as a jar file and its has all components with in server . If me make changes in one component we need to test the whole application again .

If you consider jira is a microservice application ? Can you explain ?

Server (and the DC nodes) are indeed monolithic.  In the old days, you used to be able to build it from scratch for yourself, generating a WAR or EAR distribution to be deployed on an application server.

Now, it's deployed as a bundle of a working expanded WAR distribution with a Tomcat bundled.

Cloud is different, parts of it are run as microservices.

But, yes, technically, you change any part of it, and you have to test everything.  In theory.

In reality, it depends on the change, as a lot of it is modular or isolated.  If, for example, you were to re-arrange the layout of a screen by messing with the .jsp or .vm files that render it, as long as you weren't removing things the screen is for from it, or changing the inputs or ouputs, then you wouldn't have any need to worry about testing the rest of it.

Hi Rahul,

I would definitely consider it to be a monolithic application.
