Hi All,
One of my clients is considering moving all of their servers to a cloud
computing platform - most likely Azure, but possibly AWS. This would include a
mission-critical 4D application, which is currently running on 4D Server 13.6
on in-house servers in two locations. (All servers are run
Hi Ben,
I had some experience using client on remote server and it is not easy give a
good answer because depend on the number of records, the query and records size.
My experience with a new costumer that moved his server in a remote provider
was dramatic! A developer put an image field in a t

I had the chance this year to develop a while in such situation. It's important

Ben,
i have been running 4D server from my own server in a colo for the past 12
years (since v2004). Clients connect directly via WAN, we don't use
terminal server or anything like that. The colo provides gigabit connection
to the network.

Just one quick point about running a VM on shared hardware. If there are
multiple VMs, you can't be sure what's going to happen to your access to
I/O. If the other VMs are idle, no problem. If they're using RAM, no
problem...but if they're reading to or writing from disk...that can be a
problem. So

Some examples, to illustrate…
Never use While(not(end of selection()))
I had to display or print many pictures (a kind of
Are you sure this command won't be sent to server?
Nonetheless, the result would be returned in one traffic.

Hi Alan,
no, just faith ;-)
Olivier Deschanels told me it's a "setting" and 4D is optimized to wait for the
next data query to send it at the same time. Most probably many commands (SET

Hi Arnaud,
I explicitly asked about these questions like Query (*), I was told each query
would be sent individually but won't executed until the last was sent.
Query([table];[field1]=1;*)
Query([table];&;[field2]=2;*)
Query([table;&;[field3]=3)
3 traffic would be sent. Yes, I admitted that I w

I guess that depends on how sophisticated your audience is.
We've got our own IP, our own domain and it's not in our basement. That's
at least foggy.

The "cloudiness" of the colo depends on which floor the server is located on;
the higher up the more chance of being in the clouds ;-)

Hi Arnaud,
Thanks for your test. Definitely i hope that mine is wrong. I'll do a clean
sniffer by segmenting a single client/server once I finish a little project on
hand to clear my doubt for these years. I hate being lazy:-(

I heard that 4D has been doing a lot of traffic optimization in recent version.
They might have eventually getting serious about this.
Interestingly, Read Only/read write was also one of those command I asked.
I also asked if Table/field/table name/field name would be sent to server to
resolve
Alan:
My recollection is from a Summit three years ago so I could be wrong on the
specifics but the premise is solid - reduce traffic by "grouping" commands.

I should have written "recent versions" instead of "recent version":-)
The questions I raised was many, many years ago (at least pre-v11).
As all we know, 4D performance greatly improved over the network in recent
versions including those cross table queries whick I dared not to touch before.

Hi Alan,
I'm *sure* those are read from local resources, and most proba
That's great. Many of information I got was decades ago. Laurant told me that
those commands need to access the server since some users change table/field
name in a live system. I asked if 4D access local structure resources if it's
run in compiled.
He replied that it could be done ... etc. I di
