I just want my ORACLE APEX APPLICATION along with Database installed in PC-1, and then rest of PC's just access this application via LAN cable or Wi-Fi. How can i do it without using any hosting service!?
And also want to know about the ORDS Restful Services
how to configure it for the other client systems and for the server side!?
Thanks in advance!
Oracle Apex doesn't differ to any other wesite from this point of view.
You need to setup Apex/ORDS listeners, and then you can access it from your local network like :
IpOfThePCWhereApexIsInstalled:PortConfiguredWithApex/Apex
for Example
192.178.160.1:443/Apex (if Apex is configured on port 443)
192.178.160.1:80/Apex (if Apex is configured on port 80)
This way, the browser will search for the ip inside your local network and access it.

I am developing an app with a login system in flutter. Using postgresql I can access to an external database located in a raspberry. All works perfect until the network of the device changes. So here are my questions:
How can I access to a database from a device connected to a different network? Is that possible?
If not, how could it be the correct way to do it? or what should I read and/or learn to apply this funcionality?
Thank you.
This question is not Postgres specific.
You connect to servers over TCP/IP protocol using servers IP address or it's FQDN, fully qualified domain name. If your device is mobile and changes network, you can use some dynamic IP service or your own name servers.
Setting up a port forwarding system is also possible.
I am trying to make a web page that is going to make an API call to query data in our existing remote SQL Server. When I am testing it now, my code can access the database using windows authentication, but when I deploy this web page on Azure, will my code be able to still access the remote SQL Server using windows authentication? If not, what do I need to do in order for my web page to query the data in the existing remote SQL Server?
Hybrid Connections is both a service in Azure and a feature in Azure App Service. As a service, it has uses and capabilities beyond those that are used in App Service. To learn more about Hybrid Connections and their usage outside App Service, see Azure Relay Hybrid Connections.
Within App Service, Hybrid Connections can be used to access application resources in other networks. It provides access from your app to an application endpoint. It does not enable an alternate capability to access your application. As used in App Service, each Hybrid Connection correlates to a single TCP host and port combination. This means that the Hybrid Connection endpoint can be on any operating system and any application, provided you are accessing a TCP listening port. The Hybrid Connections feature does not know or care what the application protocol is, or what you are accessing. It is simply providing network access.

I am trying to create an Autoscaling web application network over HTTP Load Balancing. The Web Server Instances are going to be connected to load balancer. Further the web instances have to be connected to mysql/cloud sql through the internal IP.
So just to conclude, I need to use the Linux Web Instance (Not App Engine) and Connect to MySql/Cloud SQL through Internal Network Only?
Is it possible?
Thanks!
It's not possible, you need to use an external IP as stated in the documentation:
Note: You must use the external (public) IP address of the GCE instance.
Also, you can find here that it's not possible to authorize a private network like the one specified:
You can not specify a private network (for example, 10.x.x.x) as an authorized network.
You should use the cloud SQL proxy.
It runs on the box providing secure access to your Cloud SQL database.
Example here for container engine: https://cloud.google.com/sql/docs/container-engine-connect
To access the CloudSQL the IP must be white listed. To white list an IP go to your project then on the side bar: Storage -> Cloud SQL. Select your instance then 'Access Control'. Under 'Authorization' click the '+' to add your IP.
Silverlight application is sitting on a server which is accessible from internet and WebApi is sitting on a server behind firewall which is not accessible via internet but can be accessible via intranet. Both Silverlight Application Server and WebApi Server can talk in intranet. Is it possible for Silverlight application which is accessed from internet to talk to WebApi?
You simply need to add a firewall rule that allows Green Server to access Red Server at a given port. You can add MAC filters, IP filters, use an ad-hoc IP in a different subnet in the Red Server, expose the API in an unusual port (not 80), use client certificates, expose the API through SSL, and many other things to protect the server inside the firewall and the communication between servers.
That's the mission of the firewall. If not, you'd simply didn't connect the networks through the firewall.
We are building a client solution that will be hosted on servers in a data-centre. It consists of several servers all related to providing the client solution. There is no internal network to protect but for some reason our UAT environment has the notion of a DMZ in the server diagram.
We have an IIS box which will have a public IP. Then we have two servers DB(Sql Server) and APP that are only on the internal lan with no public IPs. You can only RDP to these servers via VPN. Our IIS server needs sql access so port 1433 is open from IIS box(DMZ) to the sql server. We are also opening several ports from the IIS server to the APP server which hosts WCF services.
My understanding was that a DMZ was meant to protect internal private networks and that these networks should not be accessible from the DMZ but we are now opening up ports to both our APP and DB servers so they are accessible from the DMZ. In the end most of our servers are accessible from the IIS server via certain ports.
We originally wanted to setup our SQL server for AD authentication only but since our IIS server is in the DMZ and has no AD access we will be forced to enable mixed mode authentication in SQL server. This might be another security issue in it's own since we are now forced to store passwords somewhere on the IIS server to be able to auth against sql server.
Are we not perhaps missing the idea of a DMZ?
So with a system where you have a DMZ, there is also a firewall involved.
So your system should look like this I think:
SQL-server hosting internal data
Other servers needed for the company
---- firewall ----
SQL-server hosting data for web solution
AD-server (if needed)
Web-server
FTP-server (could be on the web server also)
With this setup you don't expose company-sensitive database to the outside world and you also don't open up a port in the firewall making it possible for attackers to (maybe) get access to the internal database which has company sensitive data...
Just my suggestion based on the information provided.
