I am sure this question has been asked and answered before multiple times. But unfortunately, I am still not clear. Here is my issue.
I have a JSP, Servlet application which uses MySQL as the database. I have built the WAR file as well. Now I am in need of deploying this so it can be accessed online by anyone.
I looked into lot of areas including normal web hosting. However even though the services like DailyReazor are highly secured, they provide little for MySQL, around 250 MB for the package I selected.
Now I am looking into Amazon AWS. In AWS I am expecting to deploy my aplication and make it available online.The MySQL server should not contain limits like 250MB.
But I have never ever used this service AWS before. By reading various posts, I know that Elastic Beanstalk is the easiest way to go, but still not convinced about how to deploy it properly with database access and all. And in the other hand, will they give me a web address like "www.example.com" or will they simply provide an IP address?? I am also familiar with tomcat so I need to use it.
We will not upload files (images etc) at the moment, so I believe we can manage with around 20$ per month?
I really appreciate if someone can provide a clear guidance on deploying java web applications in Amazon, with the requirements I mentioned about MySQL, Global access and so on.
Amazon RDS for MySQL is a Database-as-a-service offerring from AWS. It is scaleable up to 3TB, and has scaleable IO as well. Of course it also depends on how much you prepared to pay. they manage the DB for you (backup etc). You get a URL to connect, credentials and you are set to go.
Amazon Elastic Beanstalk uses Tomcat. So you should be familiar with that. You upload your WAR file and specify what EC2 flavor you want (CPU/MEM etc). They launch a VM that is configured with Jva and Tomcat and deploy the WAR for you. You get an IP address.
Amazon Route 53 is the DNS service, where you can assign the IP address to your domain (assuming you have one)

I have two spring boot applications with shared database. Locally everything works perfect, I can run war files (tomcat is embedded) on ports 8080 and 8081.
Question is, how I can run it on AWS?
I know, there are a lot of possibilities, but I am really a beginner and have no experience. I just tried to run it on AWS as it is (as .war files) and open ports... this is working of course. But this is not secure for PROD. Another issue, I cannot serve it as HTTPS.
My imagine is described in the picture. Probably there should be some splitter (marked as ???X1) in the front and some container for the applications (???Y1).
Please, could somebody help me here? What is the best/simplest/the most secure/best performance solution.
Q2: I am not sure, whether I should use embedded tomcats for war applications.
Thank you in advance

Launch your both apps on one Ec2 Instance( WebServer Instance) , use different ports (80,81), Launch this Ec2 instance in Public Subnet.
Launch another Instance for your Database and keep that instance in Private Subnet.
this Database instance will be accessed by only Public subnet's Instance ( WebServer Instance)..
keeping Database Instance in Private Subnet will make it secure as no one can access it other than your own webserver.
OR
Use Amazon RDS for your Database, which is managed service and secure one.
The "splitter" thing in your image would be an Application Load Balancer on AWS. And you can create free SSL certificates in AWS ACM that can be attached to the Application Load Balancer.
I have managed to create my first JEE application. Now I am trying to publish it online, I tried openshift and Amazon EC2 tutorials but none of them worked.
So is there another way to deploy it ?

If it's working locally then you're almost there.
Check this out. Will's answer should answer your question.
If you work for a company and have a server set-up there, you could reroute your domain to the company’s server and do the same. In this case, you can deploy your webapp on a virtual machine at port 80. This VM's IP address will be the one which your domain reroutes to.
The procedure is pretty much the same in both cases.
I'm currently having 2 Weblogic admin servers in 2 different domains created on the same machine.
I want to convert one of the admin server to a managed server and then use them together to deploy a Java application. Is this feasible? If yes, how?
I'm currently using Weblogic Server 10.3.
PS: I'm quite new to Weblogic domain creation and administration. Please revert for any more details needed.
The simple answer is no, however, adding a managed server to a domain is extremely simple. See the documentation here. When deploying your application you'll need to target both servers or create a cluster (also very easy), add both machines to it and give the cluster name as the target.
Note, it is generally not concidered best practice to target applications to the Admin server (although it's fine when you're developing on your local machine). If you have the resources available on your environment, you could create two managed servers and put them in a cluster. Depending on the configuration of your Admin server, you may be able to reduce it's size if memory is tight.
I have coded a Jersey based java server which is all wrapped in one excecutable jar.
I am looking for a web host service in which i can deploy the jar and run it.
I saw some dedicated servers which can do this but this is overshooting the need, any suggestions?
As per your comment I understand that you created a web application with a Jetty embedded server.
I think the best solution for you in this case is to get a virtual machine host, install JRE, upload your *.jar and run it from there. Given firewall permissions and correct configuration you should be able to receive requests on the 80 port. Cons? It costs. A lot.
Most of the Java hosts have already a servlet container running (almost always Tomcat) and you can only deploy your web application in it. Having an embedded Jetty server messes up everything for you.
I strongly suggest you to detach your web application (or as you called it REST server) from Jetty and deploy the *.war in any of the multiple free Java hosts to test it online.
EDIT
Thanks to you I made a deeper research on the topic and found an interesting guide to deploy a web application with embedded Jetty server in Heroku. I've never tried it nor I know if its free, but maybe you can give a try.
Digital Ocean work pretty well for me. Their basic packages are really cheap and you get root control over your own machine, meaning you can host whatever you want without restrictions. The only downside is that they are pretty old school - you have to set up EVERYTHING yourself, including firewalls etc. There are a lot of guides available on their website though, which makes life a lot easier!

I know this is a touch redundant but I don't have voting or comment rights yet so this is the only method for me to communicate.
Digital Ocean is a solid choice. I am paying 5$ a month for a VM with 512 Mb Ram and 20 gigs of storage (which for my use is just fine.) I am still working on my first proper deploy but as stated above there are tons of tutorials to guide you through it. I have no prior command line experience but I've managed to get the server running, Created an SSH key, uploaded my landing page and have gotten a test project using Spark as the embedded server up and functional in a matter of a few hours. The Droplets are easily scalable from what I've seen. I'm still having trouble deploying an Rest based app with Postgres as the DB but it seems more to do with the ports in play than anything else. Keep getting 404s.
Hi I'm sorry for the naivety of this problem but I need some guidance as I have confused myself greatly.
I have been tasked with creating a database(mysql) and creating a web interface for i to be interacted with. I have experience with web design and database development. Previously I have used java to interact with a DB and was hoping I could use JSP for the web interface. This is where my problem is, how I would I deploy/host this website?
I have 2 theories which are misguided:
(A). Use a cms which has a web server for me to place the jsps in?
or
(B). Use a domian/web hosting site that has a server for me to place the jsps in?
I'm totally lost and any guidance would be greatly appreciated.
Simple answer is you will require a Java Application Server to host your JSPs.
You can use Apache Tomcat, GlassFish, or some other application server to do this.
You will also need a database e.g MySQL running on your host or some other host accessible by the machine running the Java application server.
You can choose to host all of this locally or farm it out to a web host provider depending on your resources.
A CMS seems like overkill. See this link for a description of CMS and its functionality. I don't believe this is what you are looking.
I don't know exactly what you're looking for, but I think you need (B)
You need a MySQL instance running your database and a servlet container (e.g. Tomcat) to host your JSPs.
Running a CMS which is just used to use the DB that it works with is a little bit heavy for that usecase.
As suggested by Mr #cmd , yes there is no need to go for an outsourced server just to host your website, unless you need it to be visible to the world.
Else for your testing purpose, you can use Any of the Apache Tomcat, Glassfish servers for hosting the applications designed in JSP or in other web interface language.
And Inside of the JSP coding itself you may write the interaction coding with your database.
your database also can be installed in the same server.
And actually instead of a server, you may even use your PC to install the Apache Tomcat and the database and start using it.
