I have lunched AWS linus2 AMI and created database and setupAjax/ LAMP through puTTY web page in browser.Now I want to partition the application so that application itself is on one instance and the database resides on a database instance on ec2?
A typical architecture on AWS is:
An Amazon EC2 instance with the application, placed in a Public Subnet
An Amazon RDS database
The application on the EC2 instance can connect to the Amazon RDS database. The benefit of this architecture is that the EC2 instance can be updated and even replaced without impacting data stored in the database. Plus, if your application later grows to multiple EC2 instances, they can all communicate with the database.
Using an Amazon RDS database is preferable to running your own database on an Amazon EC2 instance because AWS takes care of deployment, updates and backups.

I am planning to create virtual server(Microsoft SQL Server 2019 Web on Windows Server 2019) in AWS but the costing is too high for me, to reduce the price I wanted to stop my virtual server automatically for some hours by using other AWS service.
How can I shutdown the virtual server?
Will I be able to shutdown it?
How AMI and EC2 are different in nature ?
After searching by hours I found that EC2 and RDS can be shutdown automatically but didn't find any article related to that.

To terminate an instance using the console
Before you terminate an instance, verify that you won't lose any data by checking that your Amazon EBS volumes won't be deleted on termination and that you've copied any data that you need from your instance store volumes to persistent storage, such as Amazon EBS or Amazon S3.
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
In the navigation pane, choose Instances.
Select the instance, and choose Instance state, Terminate instance.
Choose Terminate when prompted for confirmation.
Yes
The EC2 is used for creating the virtual server instance. The AMI is the EC2 virtual machines image. ECS provides container services such as docker and the AWS lambda is used to run the code without a server.

I have tried connecting through Sagemaker notebook to RDS. However, to connect to RDS, my public IP needs to be allowed for security reasons. I can see when I run this command: "curl ifconfig.me" on Sagemaker Notebook instance that public IP keeps changing from time to time.
What is the correct way to connect to RDS with notebook on sagemaker? Do I need to crawl the RDS with AWS Glue and then use Athena on crawled tables and then take the query results from S3 with Sagemaker notebook?
RDS is just a managed database running on an EC2 instance. You can connect to that database in a very same way as you would connect from an application. For example, you can use a python based DB client library (depending on what DB flavor you're using, e.g. Postgres) and configure with the connection string, as you would connect any other application to your RDS instance.
I would not recommend to connect to the RDS instance through the public interface. You can place your Notebook instance to the same VPC where your RDS instance is, thus you can talk to RDS directly through the VPC.
I have a SQL Server database running on Windows Server EC2 instance. I also have Web API (ASP.NET Core WebAPI) deployed as a Service in ECS cluster (Fargate launch type).
What connection string should I use to access this database from my web API?
Right now I'm trying:
data source=NAME_OF_THE_EC2_INSTANCE;initial
catalog=DATABASE_NAME;User
Id=USER_NAME;Password=PASSWORD;MultipleActiveResultSets=True;App=EntityFramework;Connection Timeout=10;
But it doesn't work. The error returned suggests that the app doesn't even see the database at all.
It seems you'll need to use a NAT instance/Gateway
This will enable connectivity between your Fargate instance and EC2 instance where DB is installed.
Another source and also the official documentation
"...Container instances need external network access to communicate with the Amazon ECS service endpoint, so if your container instances are running in a private VPC, they need a network address translation (NAT) instance to provide this access. For more information, see NAT Instances in the Amazon VPC User Guide."
AWS offers the option to run VMs on hardware hosts that are dedicated to a single customer (for compliance purposes, added security, etc).
This is available when using their Amazon EC2 Dedicated Instances
My question is: Do they offer similar hardware-level single-tenancy in their managed DB services ? (AWS RDS. For example using Oracle, or MySQL)
I looked for that option but cannot find it anywhere.
To run RDS on dedicated hardware, you need to create a dedicated VPC and then launch the RDS instance into that VPC. You also need to choose a DB instance class that is an approved EC2 dedicated instance type e.g. db.m3.medium.

I want to remove VPS Instance in AWS and it's RDS.How to remove the both services in my account.
Your question is confusing because the title mentions VPS, while your question mentions VPC and RDS. So, here's some definitions:
An Amazon EC2 instance is a virtual machine that runs in the AWS cloud. Some people might refer to a virtual machine as a Virtual Private Server (VPS), but within AWS the term VPS is only really used with a virtual machine provisioned via Amazon Lightsail.
An Amazon Virtual Private Cloud (VPC) is a virtual network in which resources (eg Amazon EC2 instances can be created). There is a Default VPC provided in an AWS account that should not (in general) be deleted.
Amazon Relational Database Service (RDS) provides fully-managed database instances for SQL databases such as SQL Server, My SQL, Oracle, PostgreSQL.
If you wish to remove an Amazon RDS instance, go to the RDS management console, select the instance, then in the Instance Actions menu select Delete.
See: Deleting a DB Instance
If you wish to remove an Amazon EC2 instance, go to the EC2 management console, select the instance, then go to the Actions menu and select Instance State -> Terminate.
See: Terminate Your Instance
I do not recommend that you delete your VPC unless you created it yourself.
