In the documentation shows that i should can turn on the "Public Access" in RDS Aurora database but I can't see this setting.
This is the screenshot of another RDS Instance (Not Aurora)
Anyone have any idea to fix that?
Thanks!
You are using an Aurora Serverless cluster. The publicly accessible option is only available for provisioned (non-serverless) clusters. Per the note at the bottom of the page here
Note: You can't give an Amazon Aurora Serverless DB cluster a public IP address. You can access an Aurora Serverless DB cluster only
from within a virtual private cloud (VPC), based on the Amazon VPC
service. For more information, see Using Amazon Aurora Serverless.

Hi I had checked the process suggested by aws guidelines videoand url link related to this issue, but unable to move RDS aurora serverless mysql database from public to private, can anyone please help me with this or at least tell me the viability of this process.
I am unable to proceed with the step in the above url : Remove the public subnets and add private subnets on your DB instance as it is saying both public subnets are in use, i thought to proceed, but later on I don't have the option to reboot the rds aurora mysql db
The links that you have shared are for RDS provisioned instances, to which RDS Aurora Serverless does not belong to.
The answer depends on the version of RDS Aurora Serverless (v1 or v2), which you have not given in your question:
RDS Aurora Serverless v1: While the cluster always lives inside a VPC, it is only reachable from within the same VPC, see the RDS Aurora documentation:
You can't give an Aurora Serverless v1 DB cluster a public IP address. You can access an Aurora Serverless v1 DB cluster only from within a VPC.
The cluster can never be public. Therefore, you cannot move it to a private subnet since it already is private.
For RDS Aurora Serverless v2, however, you can choose to have a public IP, but this is not the default option during creation. If yours doesn't have a public IP, then you don't need to move it into a private subnet.
Is it possible to access Aurora Serverless DB from AWS Lambda?
In my case I have a Flutter mobile application which is communicating with Lumen micro framework through RESTful API. For DB I use MySQL.
After creating AWS Aurora cluster, can I connect to it like to a normal MySQL DB connection?
DB_CONNECTION=mysql
DB_HOST=my.awshost.com
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
I am relatively new to AWS. I've been only using EC2 so far. Therefore, I am trying to getting more familiar with Serverless concept.
Any help is appreciated.
Yes, you can access like other service but there is limitation of Serverless DB, it can only accessible within VPC, so you should define Lambda in the same VPC and configure networking.
Limitations of Aurora Serverless
Aurora with MySQL version 5.6 compatibility
Aurora with PostgreSQL version 10.7 compatibility
The port number for connections must be:
3306 for Aurora MySQL
5432 for Aurora PostgreSQL
You can't give an Aurora Serverless DB cluster a public IP address. You can access an Aurora Serverless DB cluster only from within a virtual private cloud (VPC) based on the Amazon VPC service.
Each Aurora Serverless DB cluster requires two AWS PrivateLink endpoints. If you reach the limit for PrivateLink endpoints within your VPC, you can't create any more Aurora Serverless clusters in that VPC. For information about checking and changing the limits on endpoints within a VPC, see Amazon VPC Limits.
You can't access an Aurora Serverless DB cluster's endpoint through an AWS VPN connection or an inter-region VPC peering connection.

You can explore getting-started-with-the-amazon-aurora-serverless-data-api for configuration lambda with Serverless DB.
The latest DocumentDB documentation states that a jump host is necessary for accessing the database from outside its native VPC:
By design, you access Amazon DocumentDB (with MongoDB compatibility)
resources from an Amazon EC2 instance within the same Amazon VPC as
the Amazon DocumentDB resources. However, suppose that your use case
requires that you or your application access your Amazon DocumentDB
resources from outside the cluster's Amazon VPC. In that case, you can
use SSH tunneling (also known as "port forwarding") to access your
Amazon DocumentDB resources.
However, VPC sharing seems to allow multiple accounts/VPCs to share the same resources.
Is it possible to use VPC sharing to access a documentDB resource in another VPC without having to use jump hosts?
Thank you in advance for your consideration and response.
Yes.
https://aws.amazon.com/documentdb/faqs/
Amazon DocumentDB clusters deployed within a VPC can be accessed directly by EC2 instances or other AWS services that are deployed in the same VPC. Additionally, Amazon DocumentDB can be accessed by EC2 instances or other AWS services in different VPCs in the same region or other regions via VPC peering.
We will get the documentation updated.
AWS documentation states that Aurora Serverless DB cannot have a public IP Address:
You can't give an Aurora Serverless DB cluster a public IP address. You can access an Aurora Serverless DB cluster only from within a virtual private cloud (VPC) based on the Amazon VPC service.
However, this confuses me as I was just able to set "Public accessibility" to "Yes". I was also able to connect to the database outside the VPC using the endpoint specified.
Am I misunderstanding the limitations (Public IP)? Or is this something that was made possible just recently?
Thank you!
The part you quoted mentions Aurora Serverless - this is different to the Aurora you are using in your picture.
Serverless is only available inside VPC as your quote states - Standard Aurora can be made publicly accessible, although generally it's better practice to restrict access to inside VPC only.
I am tying to deploy galera cluster on aws. Is it a good idea to use VPC or making a cluster with 2-3 open ec2 instances. What are pros and cons.
Also, Is there any extra billing for VPC? Any help will be great!!
I am not sure of the variation of the installation of the GALERA on AWS VPC with EC2 instances.
One suggestion which I would add is the consideration of the RDS - Database as a service from AWS; I don't whether that would solve your need to use GALERA.
Regarding the pricing for the VPC, it is free; you only pay for the underlying EC2 instances running, Elastic IP - Data Transfer, Out Bandwidth etc. If you are going to connect your local data center to VPC using VPC/VPN gateway - that would be charged
No there is no extra cost for a VPC [but only for the resources used in it]
With Galera you can have a multi-master architecture [I have not implemented it] but with RDS you cannot. I have setup a Disaster Recovery plan with RDS where a multi-master architecture would be eliminating the downtime , but instead set it up with the use of Read Replica which would be promoted in a master. That's the way AWS RDS works.
