Re: web serving from 4D client

[Bill Weale]

If you need significant 4D Client (not web serving) involvement with 4D Server 
or if the need of the web server for 4D data and functionality is non-trivial, 
I would forget the cloud as an option. Only solution in that direction I could 
think of would be to put 4D Server and 4D Client/webserver on the same cloud 
(you know what I mean) and hope that or arrange to have the 4D Clients on 
low-latency connections to  4D Server. This can be done with dedicated routed 
circuits but can be really expensive. We do have at least one setup like Arnaud 
describes, everything in-house with webserver/client in a DMZ. 

As he suggests, one way to avoid the expense under this last scenario is to 
design your db for higher latency connections with 4D Client. I just can’t get 
my head around the concept of putting 4D Server (as server to 4D Clients) in 
the cloud. Why deny your customer much of 4D’s potential? Why deny yourself the 
chance to provide it? Sure, you can whip something up that works ok at first, 
but unless you and your customer go into the project agreeing that it’s just 
going to be a short-term throw-away…

Another option: we use 4D server and client-as-web-server both in-house, with 
the client in a DMZ. Connection to wan is fiber. It is enough for us, the web 
traffic is not huge. 

I've been working a while on a dedicated server on cloud. It works, great, but 
very often 4D application written in lan environment will need deep changes to 
be useable.

RE: web serving from 4D client

[Paul Dennis]

Hello Scott, Bill, Tim

I'm trying to decide where to host the 4Dserver application. The options are

1. 4D server inhouse and 4D Client web serving in cloud on a dedicated
server. The limitation here is the speed of our connection as this is a
consumer site and could be busy.
2. 4D server and 4D Client in cloud on same windows server
3. 4D server and 4D Client in cloud on with client running under hyper V on
same machine ie isolate the server and the client.

At the moment I'm will be going with option 2.

Any thoughts
Thanks
Paul

The machine selected to run the web server, the 4D User assigned to that 
machine (with or without a password), the HTML root file and anything else you 
wish to do to configure and authorize the WEB START SERVER call can be managed 
in 4D records and forms. And, obviously, they can be as “secure" as you are 
clever…

Re: web serving from 4D client

I can say that, as far as a version 14 built c/s system, a web serving 4D 
client can be set to auto launch while also starting the webserver. As Scott 
pointed out it’s important that the user assigned to the web server client be 
assigned to a group with web server privileges and (I’m quite sure) that group 
must not contain any more users than the number of web server licenses attached 
to the system.

Re: web serving from 4D client

Hi Scott—

It’s been a while, but I recall that there can be quirkiness involving the 
persistence, or not, of some of the settings in the configuration ui. I’ve 
worked around that by keeping them in db preferences records which can be 
modified by designer/administrator/user as appropriate. On startup (webserver 
startup in this case) those prefs can be invoked by code, using the db 
record/field values.

Re: web serving from 4D client

Scott, I am about to implement serving via client. In your setup having a
"web user" does this mean you have to login manually when you restart the
client ?
Thanks
Paul

Bill,

"Since the system is a built c/s project and we do auto updates quite often"

It's my experience in v15 that you need to reset the Default HTML root after
an update.

Scott
