How many use the Omnis WebApp Server?

[malkishtini]

Hi Bruno,

I would like to inquire about your 3rd point below:

>>3. How is the speed? Load speed and work speed?

>>My users are very pleased with the speed. v10 is faster than former versions, and the Linux version which I prefer for 
deployment is way faster than anything done by Omnis previously.

We would like to start deploying using headless servers on Linux, but when I started testing the process, I didn't succeed in loading our app (we load around 17 libs at startup) in Linux (although same app  runs as service in Windows with no issues).
So apparently our startup logic has some code that can't run under Linux. 
Did you need to do modifications to your Omnis code to make it run smoothly under Linux?

I know we have to make sure that all paths/ file system handling supports Linux, but I'm not aware of what other issues in Omnis code that we need to consider.
In our case the app was failing at startup because of notation errors from Omnis code (errors like methods are not supported or something like that, I don't recall the exact errors now, but they were annoying and it was not easy to debug the app in Linux so we stopped the project).
I'm thinking now if we need to deploy under Linux it might be easier to start with a new lib and add the modules we need to it than load the entire app and runs codes that we don't need for the server, so we have less code to worry about.
But I just like to hear some successful stories on deploying to Linux so I get the courage to continue the project :).
 
Thank you,
Mayada

Hi Mats,

I have half a dozen apps in production that use the Omnis web server 10 and the jsclient with 5 to 20 users on desktops 
and tablets. They were former Omnis 4 apps,

I also have 2 new apps that use Omnis 10 as a REST server and Vuejs for the front-end design because users are 40% 
mobiles. One of them serves around 150 unique visitors/day, you can check the public part of it, which is essentially a 
few catalogue pages here :

1. Is it hard to migrate from fat to thin client?

Yes, it is not easy, Trying to come up with a responsive page design valid for many devices, browsers and screens sizes 
is a true challenge. Splitting efficiently your code between client and server also requires more thoughtful process 
than with desktop coding. But it is way harder to restart from scratch with a new language

2. Is the price tag worth it?

The runtime price of Omnis jsclient is very low, and IMO the ODPP price is a fair price to keep the brit engineering 
team at work.

3. How is the speed? Load speed and work speed?

My users are very pleased with the speed. v10 is faster than former versions, and the Linux version which I prefer for 
deployment is way faster than anything done by Omnis previously.

4. Is it stable?

I often crash during development (on mac). It almost never crash at runtime although i've had issues when deploying 
specifically some reports, timers and external scripts calls, but I've been able to solve them so far.

On Windows servers, if you don't block automatic updates, you can have the Omnis service halted because MS decides 
suddendly to install one of their bloated update in the middle of a working day.

5. Is it secure?

Omnis works hard to give us a product that has no major security flaws, but in the end it's up to you to deliver secure 
apps, not them, You have to make sure you use secure protocols everywhere https, smtps, ftps, and encryption, hashed 
passwords, bind variables to avoid sql injection, correct CORS setup, etc... there is a lot of work to do in this area.

HTH
