How to Deploy spring boot application using Eureka Server in windows - spring-boot

If i was using apache tomcat as web server then i can simply take the Jar file and deploy in apache running in windows.
How can i deploy same when using Eureka Server in windows?
Do we have any server installation of Eureka?

Kiran, Each Spring Boot application you developed is standalone application. Whenever application is built embedded tomcat is packed inside the package. So it means it does not require extra effort for you side, just port the application to target machine and double click the application -> it will start its magic.
thus, created package is not suitable for separate running tomcat as it contains unnessary stuff.
If you don't want to deploy on separate tomcat instead of standalone then follow guide

Deploy SpringBoot Api into IIS Web Server

I created spring boot api with gradle build. everything working fine in my local.
I deployed angular app in Sites/DefaultsTest in IIS web server. it run in https://example.app.com/app
SpringBoot API base path is '/api'
I want to deploy spring boot api in same windows server machine and should able to access through Angular App globally.
please guide me.
IIS WebServer Dashboard
As far as I know, the spring boot API is a java web application, we don't suggest you directly hosted the java web application in the IIS.
I suggest you could try to install a docker or using tomcat to host the application, then you could use IIS reverse proxy to redirect the request to that API to get the result.
More details about how host the spring boot application on the docker, you could refer to below article.

Is it possible to run Spring Cloud Gateway on an external application server?

I want to create a war file of Spring Cloud Gateway Project (version 2.1.2.RELEASE) and deploy it on a container which supports reactive, is it possible? which application server is suggested?
AFAIK this is possible, but I wouldn't recommended it. If you package your application as a runnable jar it will ship with an embedded application server so it can run everywhere.

Spring boot and Tomcat : Is it better to use embeded Tomcat or external Tomcat installation.

I was wondering if some experienced spring boot users can tell us how to choose between embedded Tomcat and external Tomcat installation.
Thanks in advance.
Embedded Tomcat helps you to define Standalone application. Earlier we have to deploy war to Tomcat Server which itself a tedious task. From the embedded tomcat you can run application as service without worrying about the deployment thing. As now days microservices are being popular, spring boot is more popular because of its feature one of them is embedded servers like Tomcat,Jetty or Netty.

Cloud Foundry : Spring boot vs WAR file

I am new to the world of Cloud, CloudFoundry, Saas, PaaS, IaaS, etc.
So I have few very fundamental questions.
Who is better Spring boot or war file in terms of deploying an application or a service to a cloud using cloud foundry?
WHY ?
If I want to deploy my war file on a PaaS cloud then who kicks it off?
As in where is the server?
How will I know which server my war file is deployed to?
Is using Spring-boot with embeded tomcat for PaaS mandatory?
What if my application does not use spring-boot (no spring reference in pom as well) then can I deploy my application war file on cloud? How?
There is nothing like better in war or Spring boot jar. They both are underhood same things, where Spring boot jar manages the server embedded in it and war does not have that.
Cloud Foundry has something like BuildPacks. You need to define a buildpack when you do a cf push. If you select a java build pack it has the things required to run a war on server. It gets the Java, Tomcat Server and all other dependencies needed to run the war.
https://github.com/cloudfoundry/java-buildpack
Cloud foundry creates a droplet, which is basically the execution context with all required dependencies. This is used to run the actual VM on the cloud.
You need not know which server your war is deployed to. That is the basic idea behind the cloud deployment. It may be on a single/multiple VMs under the hood. So what you need to know is something called routes. Routes are the actual addresses to your apps. You need to create routes and bind them to your application, and later app can be accessed using the routes.
https://docs.cloudfoundry.org/devguide/deploy-apps/routes-domains.html#routes
No using embedded servers is not mandatory in Any Cloud PAAS. War can be directly deployed. All PAAS platforms has support for this. Cloud foundry way of doing this is through build packs.
CF : https://docs.cloudfoundry.org/buildpacks/
Heroku : https://devcenter.heroku.com/articles/java-webapp-runner
Any application/ non spring apps which is plain war or jar can be used to run on PAAS platforms.

Running multiple spring boot web app on tomcat

I am trying to deploy multiple spring boot web app on tomcat. All have the same application.properties.How can I split the configuration files for different app running on tomcat.
Spring Boot doesn't require an external Tomcat, because it contains its own embedded Tomcat. So you can run all of your application in it's own Tomcat on the same machine. All you have to do is to define different ports for your applications via server.port property.
