I'm trying to use the AWS free tier for host a java web application. I created an EC2 instance but i don't figure out how can I deploy the application to this instance. I was trying to use the AWS Toolkit for eclipse to deploy the web site to Elastic Beanstalk, but from here i need a second tier to deploy the application to the production.
My question is: What is the free solution to make a deploy to my EC2 instance and how?
Thank you!
If you are using Elastic Beanstalk ( which I recommend), then you should create the Beanstalk stack manually from the AWS console. Before you do that, I suggest you to terminate your other instance, because you wont use that.
The beanstalk stack will create an EC2 instance in the background, also an RDS database if you ask for it. You pay for the resources ( EC2, RDS), but no extra cost for the "Beanstalk stack".
After you having the Beanstalk stack, you can deploy it with the Eclipse plugin, or just simply generate the WAR file and upload it via the AWS console. ( On the Beanstalk page there is a place to upload a war file for deployment.)
Be aware to set the DB connection details to the RDS ( if you are using it).
Also note that the free tier is nice to warm up but not recommended for production.
When you create the Beanstalk stack make sure you create a single AZ web frontend, so you will have only 1 webserver running.

I am developing a Java Web App with the NetBeans IDE and AWS Elastic Beanstalk. I have created an RDS and S3 instance, where my application can successfully interact with both. However, my application can only interact with both RDS and S3 when the application is run locally through WildFly.
Whenever I try and deploy the application to Elastic Beanstalk, the instance becomes degraded. I believe I have configured both RDS and S3 instances correctly, i.e. attaching the correct security groups.
For debugging purposes, I created a blank Java Web App through NetBeans (generic Hello, World! JSP) and when I deployed that application to Elastic Beanstalk, the instance also became degraded. Therefore, I have concluded that whenever I deploy ANY application to Elastic Beanstalk, the instance degrades.
Why is Elastic Beanstalk degrading? Especially with a simple Hello World! application?
Any help would be greatly appreciated.
Thanks.
I am new to AWS , want to develop a cloud ready java application REST API.
The application will hit the MySQL database and produce output as JSON after querying the database.
IP:port/application?q=<query> response is JSON.
How to achieve it ? the data in MySQL is mostly static 100MB data but used very frequently.
It is very straight forward. if you already have same application running in your local system , then you can just move it to AWS , using below steps :-
spin up new ec2 instance, if you are using a free-tier then you can spin up lots of AWS resources for free , more information on https://aws.amazon.com/free/ .
install all the required s/w like Java, maven , tomcat and mysql and whatever your application is using on Ec2 instance . you can even have a free RDS (Database) instance in free tier which you can use for your application , instead of having the database installed locally on your application server.
while creating the ec2 server , configure instance security group properly for ex 8080 for http and 22 for SSH , 3306 for mysql etc. (This is important and try to be as restrtict as possible to make it safe from hackers).
build and deploy your application and access it using any REST client , by giving instance ip and application port number.
There are several resources online for AWS , you can refer https://www.youtube.com/watch?v=oS7VYX7LXUo which talks about deploying a java application to AWS.
Let me know if you need any other information.
Deploying Java apps (for example, a Spring BOOT APP) that interacts with the Amazon Relational Database Service (Amazon RDS) to the cloud is easy when using Elastic Beanstalk. An example of a Spring Boot database application that queries data from MySQL running on the cloud is documented here: https://github.com/awsdocs/aws-doc-sdk-examples/tree/master/javav2/usecases/creating_secure_spring_app
I am working on a Servlet/JSP project and I want to host it on aws.amazon.com. I have already signed up for Amazon Web Services and after signing in this page opens up and I have no idea what to do or which option to select.
I think AWS provides a lot of customization with a lot advanced technical options to choose from, but this is difficult for beginners who just want to make their site running.
My project will use these:-
JSP/Servlets
CSS
MySQL
Struts2
Tomcat WebServer
I would suggest these approaches to study:
Elastic BeanStalk - This is AWS simply hosting model. If you're not IT savy you should pursue this approach
EC2 with MySQL RDS - In this case you'll create a Virtual Machine(s) (EC2) install Tomcat and other dependencies and deploy your app. You'll then use RDS to store your data (which is MySql as a service)
EC2 only - YOu'll do the same as 2. but install your own instance of MySql. There may be AMI's offered that you can provision that will meet your application requirements.
Other reading:
Route53 if your going to use AWS for your domain records
Elastic Load Balancing if your going to need High Availability
Elastic Block Store if you want persistent disks accross VMs
Network Security Groups to secure your VMs (for 1. and 2.)
Virtual Private Cloud for additional security
CloudFormation if you want to automate provisioning
There are many articles on: AWS Architecture
There is a eclipse plugin for Amazon web services.
The AWS Toolkit provides an AWS Java web project template for use in Eclipse. The template creates a web tools platform (WTP) dynamic web project that includes the AWS SDK for Java in the project's classpath. Your AWS account credentials and a simple index.jsp file are provided to help you get started. The following instructions assume you have installed both the Eclipse IDE for Java EE Developers and the AWS Toolkit plug-in. For more information, see Setting Up the AWS Toolkit for Eclipse.

I would recommend 1st approach using Beanstalk to deploy your jsp application. There you are going to leverage all the advantages of AWS like load balancing, auto scaling, ddb and DW support and many other technologies. With Beanstalk you setup dev environment on your local machine and deploy the changes in AWS and once setup is done you are done...
May be you will need to spend some time on migrating from MySQL but that will be work on longer duration when you are going to have lot of users.
I have web service that is up and running that is in other words it is publish on my tomat on port 8080 and I can hit it through my browser now I want that my webservice to be get published on cloud so that I can pass wsdl uri to any one in the world and he can access my wsdl. Please advise how to achieve this ..!!will Amazon provide such facilities.
I've tried various options and Amazon's Elastic Beanstalk is the most seamless. You can launch your Java webservice by simply uploading a war. However, it does require an EC2 instance to be running.
Other options are Heroku and Windows Azure
Heroku has a free tier and uses Maven/Git to deploy the app to their server. https://devcenter.heroku.com/articles/deploy-a-java-web-application-that-launches-with-jetty-runner
Windows Azure also has instructions on how to deploy a java webapp on their platform. http://www.windowsazure.com/en-us/develop/java/
Given these options, In my personal opinion, the cheapest is Heroku and the most convinient is Amazon Elastic Beanstalk.
Here's the thing: I need to take a certain Java EE web app and deploy it to Amazon EC2 (which I will need to setup first) starting next month (using the http://aws.amazon.com/free/faqs/ AWS Free Tier Usage - hope it supports Tomcat + MySQL/PostgreSQL).
The problem: I have never ever deployed a Java EE app (not even a normal one on a dedicated hosting) nor have I setup an Amazon EC2 enviorment.
Are there any, idiot proof preferably, tutorials/how-to's/whatever on doing it from the very beginning (signing up to Amazon) till the very end (when your app is all up and running)?
I did find some tutorials on how to setup an Amazon EC2 instance, how to normally deploy a Java EE app but what I'm looking for is a single tutorial putting it all together.
Start with an Ubuntu AMI. Then install tomcat. Now put the WAR file of your J2EE app where tomcat can see it. You can use the AWS console to start/stop your machines, configure firewall rules that allow you to access port 80, etc. There won't be a step by step guide telling you exactly what to do, welcome to being a programmer.
Once we have the instance (like Ubuntu) running http://youtu.be/hJRSti6DsJg then, installs Glassfish (Java EE server) and configure it to work with Java EE. It depends more of the instance itself (Ubuntu) than EC2 Amazon... here a nice video (how to install Glashfish in Ubuntu + Netbeans config) http://youtu.be/CKuoDm6bqRM
Note:
Keep in mind both videos are a little old (may some adjustments are necessary)
The videos are indirectly related. But my point is: there isn't much info about Amazon AWS and Java EE, but there are a lot info about Amazon AWS and Linux, and Linux and Java EE.
Update
You can try Amazon Beanstalk (Deployment & Management) integrated with Netbeans (without Glashfish?) http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/GettingStarted.html
SSH to Elastic Beanstalk instance
http://aws.amazon.com/java/ (Amazon + Java)
Boxfuse now supports deploying Java EE applications using either Tomcat, TomEE Web Profile or TomEE Plus to AWS with a single command
boxfuse run mytomeeapp-1.0.war -env=prod
This will create an image, provision all necessary AWS infrastructure (AMIs, security groups, auto-scaling groups, launch configurations, ELBs, Elastic IPs, ...) and launch the instances. It supports blue/green zero downtime updates with Elastic IPs and ELBs.
You can find a tutorial here: https://boxfuse.com/blog/javaee-aws
