Is there any cloud computing service like e.g. Google's AppEngine or Amazon's S3 out there, that allows me to use JDBC without using some sort of proxy? I do have a MySQL server, that I can't move into the cloud, so I want to access this server directly via a JDBC connection.
If you can't migrate your database, don't move to the cloud. It would be a performance and security nightmare to have your app communicate with the database over the internet.
To answer your question more specifically:
S3 is a storage platform, so it is irrelevant to your question. Google's App Engine is only designed to interface with it's own storage system.
If you really want to do this you could use a full fledged virtual instance such as Amazon EC2, or Rackspace Cloud.
EDIT
I forgot to mention, Google now offers a MySQL service. I would assume that Java apps use jdbc to connect to it.

Is it possible to connect to on-premises Oracle DB using Azure Data Factory via a Site to Site VPN? Or am I obliged to use a Self-Hosted Integration Runtime?
Thanks
If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.
If your data store is a managed cloud data service, you can use the Azure Integration Runtime. If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list.
You can also use the managed virtual network integration runtime feature in Azure Data Factory to access the on-premises network without installing and configuring a self-hosted integration runtime.
For more information about the network security mechanisms and options supported by Data Factory, see Data access strategies.
The integration runtime provides a built-in Oracle driver. Therefore, you don't need to manually install a driver when you copy data from and to Oracle.

I have an existing spring boot application built using Gradle and i want this app to be connected to AWS RDS Postgres DB. I could not find any useful links so far to achieve this. Can someone please point me to some helpful link to achieve this ?
There are a couple of things you can check :
Is your network allowing to connecting to the external AWS instances, like firewall. Make sure you are not blocked.
You to use a certificate to connect, make sure you have installed it properly.
When setting up the Google Cloud SQL, I have to set up the allowed network so that it can access to the cloud sql instance.
I want to make my application in cloud9 to connect to the cloud sql instance, is it possible to do that? How I can get the outgoing IP address to setup?
is cloud9 an appengine app?
if yes check this article:
Configuring Instance Access
https://cloud.google.com/sql/docs/access-control#appengine
Basically you can grant individual Google App Engine applications access to a Google Cloud SQL instance.
I have an cloud sql instance up and running and have made a link using a jdbc driver to the instance ip using android studio project. I can successfully run queries from an ip address that I insert manually into the google cloud sql settings and not any other network. This makes my app accessible only from certain ip addresses. Is there a way i can authenticate my google cloud sql to all ip addresses. I do not wish to use the google app engine if possible as I believe it will only complicate my application. My app works well enough is there an easy way to access my sql from any network having supplied my username and password in the code itself?
You can use the console to authorize 0.0.0.0, which will allow connections from any IP address. However, this is not necessarily a good solution. If you embed your database's username and password in your Android app, it can be found by someone else taking apart the apk. If they do that, they will then have complete access to your database. It is more complicated, but you should put some kind of server in front of your database, and have the user authenticate with that server/application, and only have that server communicate directly with your database.
Good morning,
I have found that many of my customers have MS Access already installed on their PCs. Although Access is very limited as a data store, I have found that it is great for deploying low-cost front-ends for entry level customers.
I want to start renting a VPS, so I can host customer databases using Microsoft SQL Server 2008, which they can access using a locally stored Access front-end. I do have a few questions though:
In order to access the remotely hosted databases, and use the security features, would the VPS need to be set up as a domain controller, using AD DS? If I am hosting multiple customer databases, this is not an option.
What I envisage is being able to set up a simple MS Access front end, to access a MS SQL Server database on my VPS. For security, I would want the database to use the Windows account on the client machine to authenticate, and also to provide basic data change tracking.
Is this possible? Or, will I need to set up a server for each client and have it configured as a domain controller, etc?
You can have many databases on the same server, so for each client you d not need to setup a separate domain controller. Only the connection strings will be different.
You can use SSL for establishing connection with the remote server to make the process more secure. You can also make a few web services to play with the data (CRUD operations), this would also make things more manageable.
take care :)
