Step 1. Create an Identity and Access Management (IAM) role
In this step, you will create an IAM role that will be used to give Systems Manager permission to perform actions on your instances.
Step 2. Create an EC2 instance
In this step you will you will create an EC2 instance using the EnablesEC2ToAccessSystemsManagerRole role. This will allow the EC2 instance to be managed by Systems Manager.
Step 3. Update the Systems Manager Agent
Now that you have an EC2 instance running the Systems Manager agent, you can automate administration tasks and manage the instance. In this step, you run a pre-packaged command, called a document, that will upgrade the agent. It is best practice to update the System Manager Agent when you create a new instance.
Step 4. Run a Remote Shell Script
Now that your EC2 instance has the latest Systems Manager Agent, you can upgrade the packages on the EC2 instance. In this step, you will run a shell script through Run Command.
Step 5. Terminate Your Resources
In this step you will terminate your Systems Manager and EC2 related resources. Important: Terminating resources that are not actively being used reduces costs and is a best practice. Not terminating your resources can result in a charge.
1. Virtual network configuration
Managed Instance is your dedicated resource that is placed in Azure Virtual network with assigned private IP address. Before you create Managed Instance, you need to create Azure Virtual network using Azure portal , PowerShell , or Azure CLI .
2. Create Route table
The second prerequisite is to create Route table that will allow Managed Instance to communicate with the Azure Management Service. This is required because Managed Instance is placed in your private Virtual Network, and if it cannot communicate with Azure service that manages it it will became inaccessible .
3. Create additional subnet for Managed Instance (optional)
Managed Instance is deployed in your subnet, so you need to create it before you provision Managed Instance. If you want to put instances in default subnet and if you have not changed default route, then you can skip this step.
4. Configure subnet
The subnet (default one or new) must have a User Route Table (UDR) with 0.0.0.0/0 Next Hop Internet as the only route assigned to it. If you have created you route table with 0.0.0.0/0 Next Hop Internet route, you can assign it to the subnet where you will place Managed Instance.
5. Checklist
Finally, make sure that you have not accidentally added something that can break Managed Instance deployment or make the instance unavailable. Here are some quick rules that you need to check:

What is managed instance?
Managed Instance has the EXEC function that enables you to execute a T-SQL query on a remote linked server. We can use this function to send a query that will be executed on the serverless Synapse SQL endpoint and return the results. The following example returns the results of the remote query that is reading the file content from Azure Data Lake storage:
What is a serverless endpoint in Azure Synapse?
A serverless SQL endpoint in Azure Synapse Analytics might be a nice workaround if you need to implement a Polybase-like scenario in Azure SQL managed instance. This endpoint enables you to query and analyze a large amount of externally stored data. Synapse SQL endpoint is not a replacement for Polybase and does not have the same features. However, it can help you to implement the queries that need to access external data.
How to prepare serverless SQL endpoint?
As a first step, you need to provision your Azure Azure Synapse Analytics workspace and set up some tables. If you don’t have Synapse Analytics workspace, you can easily deploy it using the Azure portal or this Deployment template. Synapse workspace automatically deploys one serverless Synapse SQL endpoint that is everything we need for this kind of integration. You don’t need any additional resources on the Synapse side.
What is an external table in Synapse?
External tables in Synapse SQL are very similar to the Polybase external tables that can be used in SQL Server. In the following sections, we will see how to leverage these external tables in Azure SQL Managed Instance.
Can you link a serverless SQL query endpoint to a managed instance?
Since the serverless SQL query endpoint in Azure Synapse Analytics is a T-SQL compatible query engine, you can reference it using a linked server:
Can Synapse query Azure data?
With a serverless Synapse SQL endpoint we can query the files on Azure Data Lake storage using the OPENROWSET function:
Can you create an external table on a set of files?

Create a VPC to host the subnets and the subnet group for the RDS instance with the following code:
Creating a security group
Create a security group to be used by the AWS Client VPN endpoint and the RDS instance with the following code:
Creating an AWS Client VPN endpoint
Create an AWS Client VPN endpoint and attach it to the VPC with the following code. You use the client IP4 CIDR to assign IP addresses to the client connections. Use your own server certificate arn generated in the previous step.
Creating an Active directory
Because the SQL Server RDS instance also uses Windows authentication, create an Active Directory to be associated to the RDS instance:
Creating the SQL Server RDS instance
To create an RDS instance, you need to create a subnet group and a directory service AWS Identity and Access Management (IAM) role. This IAM role uses the managed IAM policy AmazonRDSDirectoryServiceAccess and allows Amazon RDS to make calls to the active directory.
