If I have to deploy Ktor Rest APIs using SQLite DB, so I need JRE or Server JRE to be installed on my server? And which version of JRE?

It depends on a particular module. Some modules require JRE 1.7 and others JRE 1.8. There is a Java client engine that requires JRE 11. You can safely use JRE 11 or JRE 1.8 (if you don't plan to use the Java engine).

My server starts like this, does that mean I'm using

Java Engine

?

embeddedServer(Netty, port = 8080, host = "0.0.0.0") {
	configureContentNegotiation()
	configureRouting()
}.start(wait = true)

Also I was looking to download JRE all I can find is 1.8 but not 11/16/17 JREs And what's the difference between Normal JRE and Server JRE?

My server starts like this, does that mean I'm using 

Java Engine

 ?

No, it's for an HTTP client https://ktor.io/docs/http-client-engines.html#java

So I guess Server JRE should be good for Ktor, right?

Yes, I think.

Thanks a lot

Now I'll have to read and understand about new topic
