I am trying to access AWS elasticsearch on external browser. The team has configured a vpc. How to expose the service externally?

I am building a webapp using NextJS. This app will have a backend with datastore that I am planning to use as AWS RDS PSQL. This RDS instance will be private within a VPC and not publicly available, now in AWS Amplify, I don't see any options for VPC, so was wondering on how the NextJS backend code connect to AWS RDS instance?
I have a Python application deployed on EKS (Elastic Kubernetes Service). This application saves large files inside an S3 bucket using the AWS SDK for Python (boto3). Both the EKS cluster and the S3 bucket are in the same region.
My question is, how is communication between the two services (EKS and S3) handled by default?
Do both services communicate directly and internally through the Amazon network, or do they communicate externally via the Internet?
If they communicate via the internet, is there a step by step guide on how to establish a direct internal connection between both services?

By default the network topology of your EKS offers route to the public AWS S3 endpoints.
Do both services communicate directly and internally through the Amazon network, or do they communicate externally via the Internet?
Your cluster needs to have network access to the said public AWS S3 endpoints. Example, worker nodes running in public subnet or the use of NAT gateway in private subnet.
...is there a step by step guide on how to establish a direct internal connection between both services?
You create VPC endpoints for S3 in the VPC that your EKS runs to ensure network communication with S3 stay within AWS network. VPC endpoints for S3 support both interface and gateway type. Try this article to learn about the basic of S3 endpoints, you can use the same method to create endpoints in the VPC where your EKS runs. Request to S3 from your pods will then use the endpoint to reach out to S3 within AWS network.
You can add S3 access to your EKS node IAM role, this link shows you how to add ECR registry access to EKS node IAM role, but it is the same for S3.
The other way is to make environment variables available in your container, see this link, though I would recommend the first way.

How to access my VPC endpoint https://vpc-xxx.us-east-1.es.amazonaws.com access from outside.
Kibana is below : https://vpc-xx.us-east-1.es.amazonaws.com/_plugin/kibana/
I am not running on Ec2 instance
From docs:
To access the default installation of Kibana for a domain that resides within a VPC, users must have access to the VPC. This process varies by network configuration, but likely involves connecting to a VPN or managed network or using a proxy server.
One way of setting up the proxy server has been explained in detail in the recent AWS blog post:
How do I use an NGINX proxy to access Kibana from outside a VPC that's using Amazon Cognito authentication?
The instruction could also be adapted to not using Congnito.
Extra links, with other, probably easier setup with ssh tunnels:

How can I use an SSH tunnel to access Kibana from outside of a VPC with Amazon Cognito authentication?
VPC endpoints are not accessible directly from outside of the VPC.
If you want to allow this you will need to use a proxy instance in your VPC that can connect to the VPC endpoint, then proxy all requests through the EC2 instance in order to access the endpoint.
More information is available here.
Is there a way to use AWS CLI to call different services such as SQS, EC2, SNS from EC2 linux instance?
The EC2 instance from where the AWS CLI command are invoked does not have access to internet. It is in private subnet. It is not using internet gateway or NAT.
Thanks,
Not possible. The CLI has to access the API endpoints for all the services you mentioned. For that the CLI needs internet access. Only service it can access without internet is the internal metadata server.
AWS Regions and Endpoints
VPC endpoints create a private connection between your VPC and an AWS service. However, currently the only supported service is S3 and none of the services listed in your question.
Currently, we support endpoints for connections with Amazon S3 only.
We'll add support for other AWS services later. Endpoints are
supported within the same region only.
I am new on AWS. I've been hosting an ASP.NET Web API on an AWS EC2 instance. I would like to access this web api securely through AWS API Gateway. I configured the AWS API gateway service successfully, however EC2 instance accepts and responses external api requests which are coming directly from the internet.
My web api should only accept and response aws api gateway requests.
What is the correct firewall rule(s) in security group of my EC2 instance? Or do I need to create a policy in AWS IAM user.
This configuration shouldn't be restrict aws internal traffic in order to allow access aws api gateway requests.
Thanks
You need to assign you EC2 instance under a security group. And configure the security group with inbound rules. Which will allow you to white list IP range, port, protocol etc.
