Re: 4D Server Hosting - The Future ?

Hi Kirk, Very interesting. Here are my experiences on running a 4D v17R5 server, client on Mac and windows: If you remember my presentation on the 2018 summit (with the SVG charts for temperature mapping), that is the one running on it. First setup: t2.micro on AWS, smallest possible and free

Re: 4D Server Hosting - The Future ?

Hey Rudy, I made a post yesterday on the thread about preemptive processes and how it works on VM. Ping me if you can't find it. You may find it useful because I posted some actual data from running a demo you can download. I ran it on my laptop and an AWS instance. The general specs of the AWS

Re: 4D Server Hosting - The Future ?

Hi Kirk, I am very interested on your progress with AWS. Can you tell me a little bit more about the kind of 4D DB you are running on it? Are you running client/server or using SQL? Do you notice speed differences between ORDA / Classic 4D? I’m asking because I am currently using AWS myself.

We host both the Server and the Client in the cloud. End users connect into the "client cloud" using Remote Desktop. Robb -- Robb Detlefs | Director, West Coast Operations & Strategic Initiatives robb.detl...@gallerysystems.com | 510.652.8950 x233 or

Re: 4D Server Hosting - The Future ?

I don't see how "cloud" hosting can be the future of 4D when LAN execution is great but WAN execution is horribly slow for the same application. Yes, you can rewrite in various ways (harder to write, understand, and maintain) but it is not an easy task. John DeSoi, Ph.D. > On Oct 10, 2019,

Re: 4D Server Hosting - The Future ?

Indeed, that is the magic of VM and SAN. They can change the truck’s engine while its traveling down the road at 60mph. I was a skeptic until I saw it in action. Hot swapping of disks, memory, even ‘blades’ with CPUs on them happens transparently. Keep in mind, though, that this is not done to

Re: 4D Server Hosting - The Future ?

The key to getting good 4D performance out of VMs is dedicated resources. Once we got the VM ‘locked’ so it wouldn’t be ’smart’ about reallocating ‘idle’ resources (disk space, cache memory etc) to other VMs performance was very good. I don’t know much about VMs, but I’m surprised that you

Re: 4D Server Hosting - The Future ?

it is a repeating cycle. change the paradigm to make more money. Once everyone that needs one has a mainframe switch to desktops, now everyone has a desktop switch to the 'cloud'. eventually it will swing back to personal/business owned devices as data security becomes a (bigger) issue BTW -

Peter, I had a discussion with Tim Nevels on another channel about this last week too. He's a big fan and maybe will weigh in here. I will not miss having to make a trip to the colo to change an SSD that died. (Hint: mirrored SSDs so you don't have to do that in the middle of the night.) It is

Thanks for your post Kirk. The guy I spoke to seemed to have it the other way around - the VM’s had 4-12 cores and the “metal” about 32. He also was of the categorical opinion that the only way to really keep applications “isolated” from each other (i.e. not bring everything else down when

Re: 4D Server Hosting - The Future ?

Peter, I am in the process of moving a database from our own hardware to and AWS instance. It's true that the most expensive part of setting it up, at this point, is getting the appropriate amount of band width and throughput speed. The other thing about VM vs metal is the whole pre-emptive

Hi Peter, Indeed, it is a brave new world, isn’t it? And like you said, it all happened transparently. At my last employer everything was virtualized. The SAN ‘guarenteed’ data uptime and redundancy. “Disks” (HDD or SSD) were ‘auto-healing’ and hardware failover was automatic. It is really
