Is it possible to connect Aurora ( MySQL ) using the jdbc driver endpoint using workbench or any other tool from my local machine.
Of course, yes. It is same as a usual Aurora database but is serverless. You can connect it by using workbench or any JDBC driver. However, the serverless Aurora cannot be assigned by a public ip, which means that the DB is not accessible from the outside of VPC. Since it is private, you cannot access it directly.
In order to access a private DB, you need a proxy instance, EC2 instance inside of the same VPC with public ip or you can use AWS Direct Connect.
There is some explanation about AWS Direct Connect that can be used to resolve your case.
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/aurora-serverless.html
This will explain how to connect the private RDS from local by pass the public EC2.

.
For those who don't want to use EC2 as a proxy and need a solution without using Direct Connect:
Have a look at Amazon Client VPN. Using this tool (in the VPC service), you can configure a connection to the VPC where the database is located and connect to it through VPN.
Here is a guide how to configure Client VPN: https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/cvpn-getting-started.html#cvpn-getting-started-certs

I'm new with golang.
I've been looking documentation of lambda-golang-AWS and still had this timeout in when invoking the function.
I've been configuring:
Elasticache cluster (1 primary node),
VPC (one same VPC for redis and lambda),
Security groups,
Subnets,
Inbound and outbound,
role
I have this primary Redis endpoint xxxxxx
I just need an example.
So, my questions are:
Can we connect Redis in Linux without an EC2 instance? Possibly try it with RDM.
How do we put AWS redis's endpoint in the main function? (do we only need the endpoint? or else)
Is it possible to connect to Redis Elasticache with only endpoint (without AUTH)?
Thanks a lot!
Can we connect Redis in Linux without an EC2 instance?
Yes, of course, why would an EC2 instance be an additional requirement? You just need to include a Redis client library in your Lambda function's deployment artifact, and configure the Elasticache cluster to allow inbound traffic from the security group assigned to the Lambda function.
How do we put AWS redis's endpoint in the main function? (do we only
need the endpoint? or else)
I would configure the endpoint as one of the Lambda function's environment variables.
Is it possible to connect to Redis Elasticache with only endpoint
(without AUTH)?
If you don't enable AUTH on Elasticache, then you can connect without AUTH. AUTH is an optional configuration setting.
I've created an Aurora MySQL serverless db cluster in AWS and I want to connect to it from my computer using mySQL Workbench. I've entered the endpoint as well as master user and password, however when I try to connect , it hangs for about one minute and then it says that cannot connect (no further info is given).
Also trying to ping the endpoint, it resolves the name but don't get any answer.
I've read all the documentation from AWS but I really cannot find how to connect. In the vpc security group I've enabled all inbound and outbound traffic on all ports and protocols. The AWS doc says to enable public access in DB settings but I cannot find such an option.
You can't give an Amazon Aurora Serverless V1 DB cluster a public IP address. You can access an Aurora Serverless V1 DB cluster only from within a virtual private cloud (VPC), based on the Amazon VPC service. For Aurora Serverless V2 you can make a cluster public. Make sure you have the proper ingress rules set up and enable public access in database configuration. For more information, see Using Amazon Aurora Serverless.

I am trying to connect to an Amazon RDS (Postgres) instance from an EC2 server via a NodeJS application using the pg npm package. The error I am receiving an error (note i'm hitting my node backend via a react app):
OPTIONS /users/login 200 0.424 ms - 2
Error fetching client from pool Error: Connection terminated due to connection timeout
I have tested the app locally and everything works perfectly (including connecting to RDS), but as soon as I run the app on the server I can't connect.
To simplify the problem, I have just typed my credentials explicitly into the NodeJS route file so I know there's no issues with environment variables etc. I then pushed my code to the server, pulled it as-is, and ran it. No luck. From a connection perspective, I just create a pool (require pool from pg) and then use pool.connect and client.query to make the request.
I feel like given that it works locally that the issue is an AWS one with my networking/security groups, but I feel like I have tried everything:
Ensured the db is set to public
Created a fresh security group and added it to EC2 and to RDS
Completely opened the ports (inbound and outbound)
Created a VPC and added to both EC2 and RDS
Checked the inbound/outbound are open on the VPC subnet NACL
Any help would be much appreciated. I am going insane
Connect to your server and try to debug the connection with telnet or a PostgreSQL client.
The most common mistakes for this error are:
RDS Security Group does not allow incoming connections from your VPC range or for the public EC2 server IP (in the case of a public database).
RDS subnet does not allow outgoing connections in NACL. Keep in mind that only the first connection occurs in the port you define in RDS, the other connections occur on other ports; but I think this is not your case once you said you could connect locally.
RDS Route Table doesn't allow connections from outside the VPC. But, again, I think that's not your case.
EC2 Security Group does not allow outgoing connections to the RDS. This case is a little trickier but it can happen if you don't set the SG properly.
The last case is that your EC2 server subnets do not allow connections to the internet. You said that you can connect locally, so I imagine that your RDS is properly set to allow public connections; however, you can have the case that you didn't connect an Internet Gateway or a NAT Gateway in your EC2 server Route Table or didn't properly configure the NACL to allow inbound/outbound connections from the internet.
I have one EC2 instance and when I check connection with psql tool by it is OK.
psql --host= etc...
Basically, AWS RDS does not provide internal IP for connection. I have to use long URL Endpoint instead.
How to provide this endpoint address to zabbix web interface installation tool?
When I use endpoint in "Database host" it fails :(
learning amazon aws these days,i've encountered a problem.To test NerdDinner app in amazon ec2,i have set up an ec2 instance with a security group that accepts connections to SQL Server port 1433,and i have created an rds instance and i added all IPs +EC 2 security group(port 1433)
using vs 2010 aws toolkit, when i try to create a database,the rds instance is still asking for my IP to be added to the db security group.See the pics.
The strange thing is that when i connect from another wifi(home wifi),i can access to the db instance.Now i can't access it from company wifi.
Is port 1433 open at your office? You might want to verify that.
