If DB Instances exists, the count of DB Instances will be listed besides the “DB Instances” item.

Here is the initial screen for choosing the DB Engine.
We can see that the default is Amazon Aurora.
SQL Server
Once we select SQL Server, we can see the editions of SQL Servers available – Express, Web, Standard, and Enterprise.
SQL Server Express
Again, we go the free route.
And, so we will choose “Microsoft SQL Server Express Edition”.

Your DB Instance Is Being Created
We are told that our “Database Instance is being created“….
And, assigned a couple of follow up items. And, those are:
- Configure Security group
- Consider Amazon Elasticache
- Memcached
- Redis-compatible in-memory cache

Here is a current list of VPC Resources
Which one is our SQL Server Instance using?
Here is one way to determine our DB Instance’s VPC:
- Access RDS Dashboard
- Region Specific URL
- Our DB Instance is adriel
- And, the VPC is vpc-75d97a11

Network ACL :- acl-2b06b44f
Security
There are a couple of choices for guiding our DB Instance availability.
Those choices are Network ACLs and Network Groups.
Security Groups

- Region Specific
Here are the Network Groups that are currently assigned to us:
Which Security Groups?
Which security groups are relevant to our VPC
- VPC
- We know that our VPC is vpc-75d97a11
- And, so we will ignore Group ID sg-a95d78ce, at this time
- And, focus on sg-32fbc955 ( default ) and sg-07fbc960 ( rds-launch-wizard )
- We know that our VPC is vpc-75d97a11
Took to the Net and found
What are the default security groups created when I set up AWS EB for the first time?
http://stackoverflow.com/questions/27829620/what-are-the-default-security-groups-created-when-i-set-up-aws-eb-for-the-first
Here is Scuba Dev’s response
- rds-launch-web
- When you manually launch an EC2 VM from the web console, AWS will provide you with the option of reusing an existing security group or creating a new one.
- When you create a new one, the default rule is SSH (port 22) and a default security group name of “launch-wizard-#“.
- default
- When you create your VPC, a default security group is created alongside with it. When EC2 instances are launched into a VPC subnet, they will have the default security group assigned to them if another is not specified. (http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_SecurityGroups.html#DefaultSecurityGroup).
It looks like either will do.
Out of curiosity let us dig deeper, by clicking on each security group and reviewing its present construct.
VPC Security Group – default
VPC Security Group – RDS Launch Wizard
Tabulated
|
Explanation
- Default
- The default group is wide open
- RDS Launch Wizard
- Type = MS SQL Server (1433)
- Product = TCP (6)
- Port Range = 1433
- Source = 207.140.111.60 / 32
- Because the subnet is 32, the range is the lone host ( 207.140.111.60 )
Specificity is good here and so we will choose the “RDC Launch Wizard”
Security Groups – RDC Launch Wizard

Get Public IP Address
Authorizing Access to an instance
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/authorizing-access-to-an-instance.html
Decide who requires access to your instance; for example, a single host or a specific network that you trust. In this case, we use your local system’s public IP address. You can get the public IP address of your local computer using a service. For example, we provide the following service: http://checkip.amazonaws.com. To locate another service that provides your IP address, use the search phrase “what is my IP address”. If you are connecting through an ISP or from behind your firewall without a static IP address, you need to find out the range of IP addresses used by client computers.
When we access http://checkip.amazonaws.com/, we received http://checkip.amazonaws.com/.
As suggested, you can simply google same, what is my ip address ( https://www.google.com/#q=what+is+my+ip+address ).
Review & Add Public IP Address
Let us expand our IP Addresses by adding our public IP Address
Here are the currently listed IP Addresses
Acknowledgement.
Only now did I notice that our public listed IP Address is the one auto-added, in the first place.

Summary
We were successfully able to create a new DB Instance.
We accessed the Virtual Private Cloud (VPC) panels to expand the IP Addresses that are allowed access to our DB.
But, unfortunately none of our attempts succeeded.
We thus reverted to making the DB Instance itself publicly available.
