I can connect my Spring Boot app on Elastic Beanstalk to my Amazon Aurora Database. I can connect MySQL Workbench to Amazon Aurora.
I have failed once already connecting my Spring Boot App on EC2 Linux to Amazon Aurora. I think it might be a security group issue. How do I connect an app on EC2 to an Amazon Aurora MySQL Database? I would like my security group to just allow my EC2 instance directly and any time I want to connect locally I do the setup each time by removing/adding my IP to the security group.
I can't use Elastic Beanstalk. Without going into details, I have a particular use case.
Just allow the private ip of your EC2 instance in the security group of your Aurora DB.
Eg. If the private IP of your EC2 instance is 10.0.0.122, then add a security group Inbound entry on the security group of aurora with below properties.
Type : MySQL/Aurora
Protocol : TCP
Port Range : 3306
Source : Custom : 10.0.0.122/32

I need proper explanation and steps to connect to an RDS database from my AWS Elastic BeanStalk Project. I have already created a RDS instance on AWS and successfully connected to it from MYSQL Workbench. After that, I have also connected it to my Elastic BeanStalk project. But still my java based website project cannot fetch data from it. Why ????
This use case is documented here:
https://github.com/awsdocs/aws-doc-sdk-examples/tree/master/javav2/usecases/Creating_rds_item_tracker
This tutorial steps you through creating a Java Spring app that is deployed to AWS Elastic Beanstalk and queries data from an RDS instance.
Please check if you can access your RDS instance from your elastic beanstalk environment when you set the RDS instance to public. If you can you have not configured your security groups to allow connections from your EB environments towards your rds instance.
Note: don't forget to set it to private again after you're done with testing.
I'm currently having issues setting up the AWS Explorer plugin in DataGrip to recognise the Aurora Serverless Clusters (MySQL). I have set up credentials from IAM in the credentials file, and can access other AWS services (if I select the dropdown "Schemas", for example, I can see the list of schemas in my org) but clicking the RDS dropdown shows "empty", and doesn't even show the list of database engines. I have tried connecting with secrets manager and using the correct secret for the DB cluster but no luck. When I try and add the database cluster as a data source, it just hangs on "Introspecting" and then the endpoint for that cluster.
I found this issue on the aws-toolkit for jetbrains github https://github.com/aws/aws-toolkit-jetbrains/issues/2124
which mentions that it could be a driver problem. I have tried changing to the mySQL driver, and that hasn't seemed to fix it. DataGrip also seems to heavily encourage using the recommended Aurora MySQL driver.
Is this a bug with DataGrip, or AWS Explorer, or am I missing something obvious? Do I need to enable SSL CAs to get AWS Explorer the correct permissions?
Thanks!
EDIT: I have gone through the prerequisites listed on the AWS docs:
I have installed the AWS CLI and AWS SAM CLI
I have installed Docker (but I haven't set up any containers - I think this is
only needed if I'm running localhost?)
I'm running Windows 10.
Aurora serverless can't be accessed from the internet. From docs:
You must create your Aurora Serverless DB cluster in an Amazon Virtual Private Cloud (Amazon VPC). Aurora Serverless DB clusters are accessible only from an Amazon VPC and can't use a public IP address.
Thus, you need to setup VPN or some proxy (e.g. ssh tunnel through a bastion host) to be able to connect to Aurora serverless from outside of AWS.
I have an ElasticBeanstalk application that uses Docker to run a small Laravel PHP API.
The app cannot connect to MySQL when running in ElasticBeanstalk.
The MySQL DB is a publically available AWS RDS instance.
I've run my Docker container locally and the app can connect just fine.
When I deploy to ElasticBeanstalk the app cannot connect...
Can anyone point me in a direction to help debug this?
SOLUTION
For anyone else who stumbles on this:
The solution was to create a new security group for both the EC2 instances and the RDS database. The two security groups opened up access via port 3306 for the instances and the database.
I also ensured the EC2 instances were available across every subnet and in the same VPC as my database.
Taken from the answers below and bit of help from a SysOps friend of mine.
You may want to check the EC2 Security Group Rules attached to Elastic Beanstalk to allow TCP at port 3306 for MYSQL type.
High chance that your ec2 instance does not have a public ip assigned to it. If you're trying to connect to the public IP of RDS without a public ip on the ec2 instance you won't be able to.
The ec2 instance will either need a public ip or it will need to have external internet connectivity through NAT.
We have mysql databases which we want to host on AWS RDS and want to use in Azure VM and web app. Both of them located in Singapore region.
Is this possible? If yes, How? What are pros and cons? And how to do this?
You have two options, build a Amazon VPC /Azure Network VPN tunnel by your own, with something like a cisco instance or linux vpn packages, or make your mysql amazon rds public accessible and set up ssl encrypt connection to the db for more information see this doc

I've just started working with AWS EC2 instances, and I want to migrate the MySQL DB on the EC2 to a RDS instance.
My question is about security, when I connect to my EC2 instance I use a security key (.pem) file to encrypt my connection from laptop to EC2. But when the EC2 connects to the RDS i believe it will be using port 3306 on the RDS and be unencrypted? Is this a security risk for my web application?
If this is a security risk what is the best practice for securely connecting the EC2 to the RDS?
Thanks!

Can I encrypt connections between my application and my DB Instance using SSL?
Yes, however, this option is currently only supported for the MySQL, SQL Server, and PostgreSQL engines.
Amazon RDS generates an SSL certificate for each DB Instance. Once an encrypted connection is established, data transferred between the DB Instance and your application will be encrypted during transfer. If you require your data to be encrypted while “at rest” in the database, your application must manage the encryption and decryption of data. Also note that SSL support within Amazon RDS is for encrypting the connection between your application and your DB Instance; it should not be relied on for authenticating the DB Instance itself.
http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_MySQL.html#MySQL.Concepts.SSLSupport
You can setup rules in your security group to only allow connections to your rds instance from a pre-dfined list of ec2 ip's if you want (or any ips for that matter). AWS will reject any traffic trying to get to that RDS that is not in the list.
