What is the preferred way of deploying a compojure/sinatra applications? I have multiple sites running on the host so i can't run jetty/mongrel on port 80. How should i handle multiple sites/applications running at the same host?
Use a web server such as Apache that runs on port 80 and use virtual hosts to direct the traffic to the right app server. So basically you would run each application server (jetty/mongrel, etc.) on a different port and then in each virtual host would have a different configuration to use something like mod proxy to forward the traffic to the app server. You could use a different web server such as lighttpd or nginx. For the sinatra app you could also look at Phusion Passenger, a.k.a mod rails, a.k.a mod rack, which theoretically works with any rack app, although I've only used it with Rails.
If you look into it some more you'll find that there are various schemes for forwarding traffic to the app server from a web server, but the basic mechanism for doing this kind of thing always boils down to having a web server that listens on port 80 that uses name-based virtual hosts to then forward the traffic to the appropriate app.
I've been doing this kind of thing with various standalone servers (e.g., AllegroServe) for years. I've found the best approach to be:
Run each server on a different, non-privileged port (such as 8080)
Run pound (or Nginx etc.) on 80, configured to map requests to each application.
Pound is great, and the configurations end up very simple (unlike Nginx). It will also do SSL fronting and HTTP sanitization for you, which takes the burden off your application.
Use passenger! http://modrails.com - it is a plugin for apache and nginx that lets you (very) easily run a ruby app as a virtual host

I have developed a Jooby-Application which is hosted on a netty server. I can access the application on localhost and tests were fine. Now I want to make the app accessable over internet and dont know what is the best way to reach this goal?
The complete application is hosted on a Windows Server, because it uses Excel. (Read/Write over Apache POI. For macros it has to be Windows) Should I try to connect the running netty-server with IIS or can I just forward the requests from outside to localhost? The last mentioned approach propably is a bad idea regarding security issues.
It works with reverse proxy over IIS. I had to install some features like Application Request Routing and URL Rewrite. Then I can start the jooby application (netty server) as usual on a specific port at localhost and set a reverse proxy to it.
I am not sure why being on a window is necessary, anyways, Netty is just a Java network programming framework, it can run on any platform where Java is installed.
You need to host a server, you can buy a VPS, install windows as OS, install Java, you can run your application as you like.
What I understand is you need to test it, for that you can use any port forwarding service like https://pagekite.net/support/intro/features/ to enable "world access" to localhost
When installing ASP.NET Core apps on a windows machine, I used to install the websites within IIS, I used the bindings there to route depending on the URL to the correct web application and I used Letsencrypt to create the SSL certificates.
Now I want to start shipping my applications using Docker. The samples show, how to easily create an ASP.NET Core dockerized project, but that's where most of them end. So in the end I've got an ASP.NET application in my docker running listening on port 5000.
Are there any suggestion or resources showing how to set it up on a production system?
multiple web sites listening on the standard ports 80 and 443 and forwaring to the correct docker image
SSL certificate handling
Setup ngingx as a front end. It is world-class solution, used by top-traffic sites as a front-end for incoming requests.
Among other features it does:
Redirecting based on plenty of rules
SSL management (you can use unencrypted connections behind it)
Load balancing
It is free and available as docker image.
So, you open only ngingx outside your docker network, and make it route all your traffic inside.
Setup reverse proxy like nginx, even in IIS also you redirect to corresponding docker service having a particular port. You can fan out traffic to respective ports.

I have many spring boot jars running in different ports. Say 9087-9090. I have a domain say
mydomain.com.
I can access mydomain.com:9087/ and use the application. Also mydomain.com:9088/ and use another application but how can i use them just like mydomain.com and still map them to desired ports. What is the technical term for this.
I use digitalocean hosting and have a Ubuntu 14.04 x64 Box. I'm running Java 7 in it.
You need a reverse proxy (a.k.az front end load balancer) with URL rewriting. I'm not sure what you hosting solution offers or permits, but you could try nginx or Apache httpd if you want something running locally. There are also service providers you might be able to use outside your host.
Given a local, multi-tenant dev environment (Win7 Ultimate) where host entries resolve to localhost and requests to multiple local hosts are made on :80 (etc), what's a sane way to proxy requests to either IIS (listening locally on an arbitrary static port) or another backend (i.e. a VBox VM listening on :80 on one of its own interfaces)? Basically, what's the simplest way to balance between different web servers on a FQDN/hostname basis from a common address?
As far as I can tell, ARR seems like it might be a little much config-wise, so I'm hoping to do something a la nginx/HAProxy/Pound/etc where proxying can be configured per the Host HTTP header.
I have a web server that responds to a number of different sites on port 80. Currently, IIS does the mapping to various sites via host headers, but I'd like to be able to serve other web apps on port 80 hosted in Jetty or Tomcat. IIS prevents that by grabbing all port 80 traffic.
I basically need a reverse proxy to just change the port number to something that another app stack can listen in on. I was looking into nginx but it seems to not be quite ready for prime time on Windows. Eventually I may set up a Linux box specifically for this, but for now I'm interested in a solution which will run all on the same box.
All I really need is something very light which mostly just matches hostname/port and allows rewriting of the port. Does anyone have any suggestions?
If you are running in IIS 7 or above you can use Application Request Routing for that: http://www.iis.net/download/ApplicationRequestRouting
For IIS 5-6, it looks like Apache Tomcat Connector (JK 1.2) is a clean solution. This is an IIS ISAPI filter which allows IIS to act as a reverse proxy for other web servers. It uses Apache JServ Protocol (AJP) to communicate with the app server actually serving requests. Both Tomcat and Jetty implement AJP. URLs are mapped with regex-like config to a particular AJP server instance.
Overview: http://www.iisadmin.co.uk/?p=40&page=3
IIS Config: http://tomcat.apache.org/connectors-doc/reference/iis.html
Mapping Config: http://tomcat.apache.org/connectors-doc/reference/workers.html
This ISAPI plug-in also works with IIS 7.x, but in that case the Application Request Routing (see marked answer) should be considered as it might work better with non-AJP servers.
