I have deployed Spring MVC & MySQL based application on Amazon Elastic Beanstalk. The RDS instance of MySQL is working perfectly. I deployed my application war on Beanstalk using Tomcat 6 (which is referring to RDS instance) and the EC2 instance is running successfully as per the AWS Management Console intimation but while accessing application URL I am facing the following issue
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
Note: Availing free services of AWS. I have defined instance type as small for RDS and medium for web application and do have S3 instance with 36mb data.
Could any one suggest me what would be the problem?
I resolved the issue by creating EC2 security Groups to the DB instance.

Deployed One laravel app on AWS Elastic Beanstalk & EKS Cluster Using Same Database
RDS
Why I am getting fast Response in Elastic Beanstalk while in EKS there delay of 3.02 ms.
there not much data in database
I found the issue of network. it was network between EKS & RDS so taking too much time to load the whole website.
For elastic beanstalks connection with RDS is from outside and speedy so site loading time was less over there.
I am new to AWS ElasticBeanstalk. As i have started working on AWS ElasticBeanstalk i have some confusion which are as follows.
1.Does Amazon charge for every EC2 instance which is created to run ElasticBeanstalk app under free tier.
2.Is it possible to host multiple app under samne EC2 instance which is created for Elasticbeanstalk i.e ASp.net ,Web Api and angular 4 app under same elasticbeanstalk.
Please help me to clear my issues.
Thanks
If the EC2 instances used for Elastic Beanstalk fall under the free tier (i.e. within the first 12 months of account ownership, they're small enough instances, use less than 750 hours/month, etc.), then they'll be free. It doesn't matter if the instances are used for an Elastic Beanstalk application or something else.
Yes, it is possible to host multiple Elastic Beanstalk applications on the same EC2 instance. See this related StackOverflow question.
I have the instance of MySQL db in RDS AWS and in my java web application I changed all the url for the new instance of db connection since I didn't write it in property file, my WAR file is working with the news instance when I have deployed it on local tomcat but when I deployed it in Elastic Beanstalk Application, it is not working, do you know the reason?
I have started using elastic beanstalk with tomcat8-java8 application. Elastic beanstalk setup a nice application with RDS data tier. Is it possible to add another instance, which I created manually, in data tier as a redis caching server.
Thanks for any feedbacks.
There's nothing about Elastic Beanstalk that says it cannot communicate with other servers.
An application running under Elastic Beanstalk can access other resources such as S3 buckets, databases, and other servers, etc. as long as the various permission levels allow (VPC, security groups, etc.)
So you can add a redis server manually that your Elastic Beanstalk application can utilize. You just need to ensure that your application can "get to" the redis server.
I have developed an application using Amazon Java web project from eclipse console, If I try to publish the project, its not publishing and showing error like this and this. Is only possibility to create a web project in Amazon services is through Elastic Beanstalk or else we can create a web project of our own and can be uploaded normally with EC2 instance???. If the question is foolish, please forgive. Am a newbie to Amazon services.
Elastic Beanstalk is a managed option. But you can deploy your application on to your own instances.
