Helma vs Broadvision

[Ruben Trancoso]

Hi folks,

I just started to work with Broadvision in a a legacy system that in future should be migrated to a more up to date technology. I came across Helma doing a research about alternate technologies to replace the BV platform, but until know I dont have any deep knowledge of Helma features and capacity. On the other hand to know about how much helma can replace bv should be of a great help.

Anyone in this list should enlist this comparision or give some grasp?

Hi Ruben!

(Sorry for answering so late)
I once (already a few years ago) was part of a team which implemented a
big portal website in broadvision One-To-One. (it was omv.com)

I did not do all the really hardcore development with broadvision, but
made a view modules of the website and also some server-administration

Some things i can remember:

-) Broadvision License and Support was _really_ expensive (Helma is free
and Helma developers do not cost as much as Broadvision-Consultants)
-) Setup of a Broadvision-System (for development for example) was a
very complicated procedure and took hours (A simple Helma is up and
running in a few Minutes)
-) Our Broadvision Portal needed eleven big IBM Servers to run smoothly.
The _special_ hardware was quite expensive. I don't know about any
Helma-App this size, but www.twoday.net (which is the biggest german
speaking blog-site) runs on a few _cheap_ servers with PC architecture.
-) Broadvision Application had quite a lot of complicated config-files
to configure. If anything was wrong the problem could be on a lot of
places in the app. Configuration of Helma-Apps is quite easy.
-) Handling load balancing was really good in Broadvision, the also had
some quite good always online feature. (so when you rebooted some
servers of the cluster no one every noticed this because the current
sessions stayed online till they finished, new sessions were prohibited,
after all session where gone it was rebooted automatically) For
clustering there is Helma-Swarm. I have not used it myself so i only can
tell that i have never heard someone who uses it complaining about Helma
Swarm.

So i would use Helma instead of Broadvision, no matter how big the
application should be. If Helma apps are developed right they are quite
well arranged and easy for new developers to join in.

Hope that helps a little,
Anton
