I am new to AWS Lightsail. I have created Windows Server Instance. Also have mapped to a static IP address. I am trying to accessing using the static IP from internet. It is not getting connected.
Request if you could help me, what other configuration is required to be able to access the server using the static IP.
My instance: Lightsail_KI_Windows_Server_2016-1
request your help.
regards

I'm trying to setup an Azure SQL database using P2S VPN for users who are remote working. They are using some applications like SSMS and Visual Studio that require access to the database. We allow them to connect by white listing their IP addresses but we would like to stop this and to use the deny public network access option on the SQL server on Azure.
Whenever I try to connect using SSMS I get the following message:
I've followed the steps outlined in the documentation and tutorials on MS Docs but I have not been able to get the private endpoint to work with the database.
I have created the virtual network gateway and connected it to Azure Active Directory and I can see the sessions being created by the users as they log in.
I have created the virtual network using the address range = 10.1.0.0/16 and the subnet address range = 10.1.0.0/24. I have attached the private endpoint connection to the Azure SQL server and added the virtual network to the firewall.
Is there some setting required to allow the user to connect to the database from their PC without whitelisting IP addresses?
WAY 1:
You may Use domain name instead of IP directly from your virtual
network. So, you need some service in Azure which can translate domain
name to IP.
It is necessary to properly configure your DNS settings to resolve the private endpoint IP address to the fully qualified domain name (FQDN) of the connection string.
Use a DNS forwarder for on-premises workloads to resolve the FQDN of a private endpoint, to resolve the Azure service public DNS zone in Azure.
A DNS forwarder is a Virtual Machine running on the Virtual Network
linked to the Private DNS Zone that can proxy DNS queries coming from
other Virtual Networks or from on-premises. This is required as the
query must be originated from the Virtual Network to Azure DNS.
.
Use the host file on a virtual machine to override the DNS: Azure
creates a canonical name DNS record (CNAME) on the public DNS. The
CNAME record redirects the resolution to the private domain name
(privatelink.database.windows.net). You can override the resolution
with the private IP address of your private
endpoints. See azure-provided-name-resolution.

WAY 2 :
You may go for SQL managed instance which is another Azure SQL
PaaS offering .It is deployed with in VNet with no public service
endpoints and uses root and client certificates to authenticate in
azure.
(Go for this when one prefers not to use Private endpoint:)

I am new to Amazon Web service. I created an Ubuntu 16 instance with AWS. Installed Apache and restarted the service. But still I am unable to figure out how to access the start page from a browser. Which IP address should I use? Public ip or elastic ip? Also do I need to change any configuration file? Thanks.
You need to use the public IP address, depending on your usecase you can even use an elastic IP address.
However you need to configure your security groups in order to access the web page.
Go to your security groups
Select the relevant security group
Add inbound rule to port 80 (TCP)
Then you will be able to access the page. Please refer this guide for more information.
You can use public ip / public DNS. These both will change upon restart of an instance. Elastic IP is useful when you want your IP address to be persistent. e.g. To make an entry in your domain DNS records.
Make sure your default site is pointing to correct directory as you are going to access using IP address.
If your instance is in VPC then it must be in public subnet. (subnet with Internet Gateway route attached)
I am following Tutorial: Installing a LAMP Web Server on Amazon Linux. My web server is started.
Now how do I access the website from my browser?
You will need to assign a Public IP address to your Amazon EC2 instance. This can be done at startup by enabling Auto-assign Public IP, or it can be done later by assigning an Elastic IP address:
Create an Elastic IP address in the Amazon EC2 console
Associate it to your Amazon EC2 instance
You will also want to check that the Security Group associated with your instance is permitting inbound HTTP traffic (port 80).
Then, just put the IP address of your instance into your web browser.
I have created a Virtual Machine in Bluemix. I have installed NGINX web server on it. To access the web application that is deployed on NGINX, should I use a public IP address (for e.g. http://123.456.78.9) or is there a domain name associated with the instance (something like http://abcxyz.bluemix.net)?
When you launch any VM in cloud by default they should be not accessible from public internet unless you attach a public ip address to them.
Once you have attached a public ip address to your instance and configured the firewalls to allow incoming connections (http, ssh etc) you can update your DNS server to redirect traffic there.
AWS create a public FQDN at the time of launching the ec2 instances as
ec2-nn-nn-nn-nn-region-compute.com (where nn are ip address bits), not sure any similar thing with bluemix but it is less likely to have abcxyz.bluemix.
My setup is an infinispan 8.1.2 server running on AWS using a distributed cache. For local development, I would like to be able to connect to the instance on AWS, but the server will only start using either 0.0.0.0 or the AWS private IP address. Since JGroups does not work with the 0.0.0.0 address it seems my only option would be to use the AWS private IP. But this address is not accessible remotely!
Has anyone else run infinispan server and tried to connect from a different subnet?
Not sure if this helps but anyway...
You do have a public IP address on AWS, which you can query with some HTTP command (check the docs).
Now, if you can add a NATting rule which forwards traffic between the private and public address, you could use external_addr and external_port in TCP to bind to the private address, but send traffic to the public address.
This would allow you to access a JGroups node from another subnet, or even the internet. You probably have to modify your security policy and expose the externally accessible ports. YMMV
