Where do the Couchbase Server services reside? In the server, or inside a Bucket?
Server
When you add a node you define the services it performs
Only nodes with the data service can hold bucket data

I am a newbie in software architecture and I have some question:
I don't understand which requests is sent to the HAProxy on this image.
I mean: if one "Application" Server (backend) want to save data in the Galera Cluster
what is the request that will be sent to the HAProxy?
Is it an sql query "request"?
If it is an sql query should the HAProxy server needs a mysql-server to "handle" the connection?
Should Application Server needs to be configured to make an sql connection to the HAProxy?

Thanks!
The application only needs to know the IP address of the VIP in this architecture. The app connects to that VIP using a MySQL connector, as if it is a MySQL Server.
The "requests" are then stateful TCP/IP connections using the MySQL protocol, just as if the app were connected directly to a MySQL node.
This is not a series of stateless http requests. You might be assuming that HAProxy is only for load-balancing http requests. In fact, HAProxy can be used for other protocols than http.
I have an azure hosted MySQL data base and am now trying to use the MySQL connector in a logic app. Unfortunately the connector requires an on premise gateway as one of the mandatory requirements. I have read that I should disable SSL which is already the case. Any idea how I can make a connection to this DB?
MySql connector in logic app at this point allows you to connect to the on premises mysql database through an on premises datagateway. You cannot directly connect to the mysql database hosted on azure. The workaround for this is that you write an azure function which connects with the mysql databases and call the azure function in your logic app. The azure function can be a http triggered
We have an ASP.NET MVC 5 web application that reads data locally from within the same server. This server is in Europe. However when trying to read the same data from an AWS server based in Sidney the lag is many times greater. A ping from our local server to the AWS server in Australia takes 5 seconds. The data needs to be located in Australia because of data protection laws issued by the Australian Government. The database is MySQL. We have created a VPN between both servers and made no difference.
What are our options in order to improve the speed between these two servers?
If it is a web application serving content to users over internet you can use CloudFront distribution to reduce your latency issues.

If you are trying to connect your servers from your data center to AWS
Use AWS Direct Connect, this will provide a dedicated link between your on-premise datacenter and to the AWS Servers; Decreasing your latency by a lot.

AWS runs your application regardless of which platform(ASP.NET, JAVA, C...) it is, AWS only provisions infrastructure. You don't need to worry about the platform on which your application is running and what database it connects to. You just need to ensure that all the network connections are properly open so that your servers can communicate with AWS servers.
I have an application connecting to Google cloud SQL from a GCE instance. Is the traffic encrypted between MySQL instance and my GCE instance?
Thanks
Customer data is encrypted when in Google's internal network. External connections can be encrypted using SSL. You can find more info at this link
I had hosted my site on Azure and my database to azure sql databse but the problem with azure sql database does not support data encryption and for that reason I have to move my sql database to external server.
Now I do not know how I can connect that sql database to azure site?
I found one solution to use service bus but they used WCF console application as a service bus listener which I do not know how to create and host WCF.
I appreciate code sample if anything I need to do in my code or application other than connection string setup.
