I have an t3.xlarge instance on EC2. In this EC2 I have installed the SQL SERVER
2019 Express with Advance Option to runs the SSRS. I can successfully connect this SQL Server with my non-AWS local area network but this possible whenever I disable my Windows Firewall. The problem is there when I disable the Windows Firewall I am not able to connect the DB with my LAN.
What I have already did
Made the entries for port 1433,1434 and 80 in the inbound rule EC2 Windows Firewall and Advance Security.
Made the entries for port 1433,1434 and 80 in the outbound rule EC2 Windows Firewall and Advance Security.
Made the entries for port 1433,1434 and 80 in the inbound rule EC2 Security Group.
Made the entries for port 1433,1434 and 80 in the outbound rule EC2 Security Group.
All of my SQL Server Configuration is enabled (TCP/IP).

I am unable to connect my RDS SQL Server instance from my AWS EC2 instance.
I have installed SQL Server Management Studio on my AWS EC2 Windows Server 2019 instance.
I am neither able to ping my RDS endpoint from that machine nor able to connect using SSMS. In the security group inbound rules for RDS I have entered IP of my EC2 instance under all traffic option, also tried using SQL Server option in security inbound rules.
There's two key questions that are relevant here: 1) is the connectivity allowed in AWS, and 2) is the connectivity allowed by the host/applications on the individual instances.
For 1, you need visibility into the networking aspect of your cloud. I use Batfish's virtual traceroute in your environment. There's an free and open source project (https://batfish.org) or you can try a free trial of the enterprise offering (https://www.intentionet.com/trial).
After you validate that the traffic is allowed in AWS (no Network ACLs or security groups are misconfigured, vpc peerings / routing tables are correct, etc.) you should move on to verifying application config on the actual hosts.
(Disclaimer: I work on Batfish and Batfish Enterprise).
What you need to do is:
The security group that you have attached to the RDS instance you need to add a rule for the inbound section of the security group to be SQL Server and have the source of that rule be the same name as the security group, this is called a self referencing security group rule. Then go to the EC2 instance and attach that same security group to the instance. This will solve the Security Group potential problem.
The other piece you need to check is if the EC2 instance is in a different subnet than the RDS SQL Server you need to make sure the Network Access Control List (NACL) will allow the inbound/outbound traffic of SQL between the subnets.
I created a sql database in the azure (PAAS) and trying to connect using SSMS 2017.
Unfortunately, I do not have admin rights to my machine. considering this, Can you please let me know what are my options in connecting to azure sql db?
Here is the error I am seeing.
Since your company network has port 1433 blocked, you can try the following. Most companies have a free WIFI for guests or visitors, use that WIFI to connect to your company using a VPN client like FortiClient, Citrix Workspace or SonicWall NetExtender. While connected to your company network with these clients you may still be able to connect to Azure SQL Database.
Make sure Windows Firewall or other security software do not have port 1433 blocked also.
I want to connect to the database which is on Amazon AWS VM from azure website.
It is giving error "not accessible"
Any configuration I have to made in AWS VM
You need to setup a security group and open up inbound and outbound ports in AWS.
Only after your sql server port is opened you can connect to your sserver from Azure.
If you are using MySql which uses 3306 port by default (you need to change this for security reasons), you need to open up 3306 to recieve and throw bytes.

Have you checked your network firewall settings in both azure and aws? I suspect that's your issue. Create exceptions for the proper IP addresses.
I am setting up a system that runs on Azure but needs to access an on-premises SQL Server. I've built it out as detailed in this article. This calls for me opening port 1433 to the world which looks like a serious security problem. Is there any way to open that port and still have it secure (I know that I can have complex user ids and passwords and everything, but is there a better way to secure SQL Server)
The connection between your on-premises DB and Windows Azure Connect will be secure by default via the IPSEC protocol
"Windows Azure Connect uses industry-standard end-to-end IPSEC
protocol to establish secure connections between on-premise machines
and roles in the cloud. Unlike a traditional Virtual Private Network
(VPN), which establishes secure connectivity at gateway level, Windows
Azure Connect offers more granular control by establishing secure
connections at a machine and role level."

Your DB won't be publicly available, only VM's on the Azure Connect will be able to see it.
Your traditional firewall and on-premises security policies and procedures will still hide your DB in your Enterprise Environment, all you are doing is giving Windows Azure VM (Roles) the ability to see it.
I saw the comment discussion on #user728584's answer about opening port 1433. Port 1433 has nothing to do with Azure Connect, which is essentially a VPN tunnel between on-prem boxes and a collection of Windows Azure role instances. Azure Connect requires an agent to be installed on any on-prem server you're adding to the Connect Group and doesn't require an inbound port to be opened. In your case, you'd add the agent to your SQL Server box, which would then be part of the connect group and accessible directly from your Windows Azure Role instances (for the roles you add to the group). The Connect Agent then establishes the tunnel.
The Connect Agent has a special key baked in, generated for you, making it unique. But even if someone somehow obtained the installer for your specific Connect Agent, it wouldn't help at all, as you still need to add that node to the Connect Group. So, this is a secure setup.
