AWS lightsail
Hi, all,
If I use AWS lightsail, after I install openmeeings, do I need to follow
this instruction?
Installation SSL certificates and Coturn for OpenMeetings 5.0.0-M4 on
Ubuntu 18.04.pdf
<https://cwiki.apache.org/confluence/download/attachments/27838216/Installation%20SSL%20certificates%20and%20Coturn%20for%20OpenMeetings%205.0.0-M4%20on%20Ubuntu%2018.04.pdf?version=1&modificationDate=1587558435000&api=v2>
It seems that this instruction is for a server behind a NAT. I think AWS
lightsail is not behind a NAT, right?
Thanks,
Tom

Hi there guys. I thought I’d throw in my 2 cents in on this. I am using an AWS EC2 instance. From my understand all instances are behind NAT which as a result requires a Turnserver. In one of my previous emails I described the approach I took (check the OM user forum). I am using my phone to write this email... so as you can imagine searching, copying and pasting a link to the actual message would be a little cumbersome... but the subject of the email is “Suggested AWS EC2 setup - OM 5.0.0 M3 / Ubuntu 18.04”. For the moment the instance I am running is as follows:
LAMP image (Linux, Apache, MySQL, and PHP setup). My AWS Setup is as follows:
Instance type: t3a.large (8 gigs Ram , 2 vCPUS), I was previously using a t3a.medium (4 gigs Ram , 2 vCPUS)… which seemed to run okay… but needed to elimate any doubts I had by cranking up the RAM. Some of you may decide to go for lower or higher instances depending on your budget and desired performance levels etc.
For reference this instance is costing me about $50 dollars. But would be a lot cheaper if I didn’t use AWS’s Route 52 (domain to designated IP address).
I had run everything on a free tier a couple of years back but document conversion was slow and often crashed.
I have been and a couple of my guys have been running simultaneous classes over the last few weeks and generally speaking everything has been fine. A few browser issues as mentioned in a previous email... but it is important to state I am using OM M3, which I will update and configure at the weekend. Some classes we 1hr 30 mins, some 5 hours on a Saturday. Average meeting 5 - 8 people.
My short to long term plan would be to set up a “clustering” model which was discussed in the forum a few weeks back, maybe longer... having the database in one AWS “bucket” and several other instances.
I would be happy to help out in any way regarding load testing. I’ll be honest I’d be hard fetched to ask my students to participate... but I have about 5 computers at home since I’ve been in quarantine and happy to participate where as Maxim stated... 4 can participate on a “silent” basis. Given the amount of people in the group... I’d say a “call for action” email to all the users will be received well and more people might be able to help with a load test as Sebastian mentioned.
Either way, I’m here to help in any way.
I’ve been out of the loop for the last few weeks but, again, if there is any way I can continue to help in any way I will.
All the best, Denis.

Hello Tom,
OM 5.0.x is based on WebRTC
WebRTC is peer-to-peer technology
So not only your users should be able to connect your server but the server
should be able to connect to user
This is where TURN can help

2GB memory is on the very minimum side of spec.
Even if you just load a big document to the server to convert it and create
a bunch of slides to show on the whiteboard it will exceed limits quickly.
Same with multiple people streaming.
So you won't see this problem yet, but you will soon.
Coturn is a feature required to resolve networking issues. The question is
not related to hardware or not. Its a tool to improve network, and yes,
probably you will need it in order to help certain users to resolve IP and
network addresses. But it depends a bit on if your users are behind
router/firewalls or inside an controlled intranet.
It helps not only on the server side but also on the client side.

Hi, Seb,
Thanks for your reply. I choose a 2GB memory lightsail instance and I think
it can run openmeetings.
I am not using any container right now.
As for the Linux command line tools, I don't know what you mean. I can ssh
to my lightsail and perform all the commands I want.
So, I don't feel this is a problem.
Actually, my question is if I use lightsail, do I need to install Coturn
mentioned in?
Installation SSL certificates and Coturn for OpenMeetings 5.0.0-M4 on
Ubuntu 18.04.pdf
<https://cwiki.apache.org/confluence/download/attachments/27838216/Installation%20SSL%20certificates%20and%20Coturn%20for%20OpenMeetings%205.0.0-M4%20on%20Ubuntu%2018.04.pdf?version=1&modificationDate=1587558435000&api=v2>
I feel I don't need to install Coturn because I am not running my VPS
behind a NAT.
I just want to confirm this point.
Thanks,
Tom

Might be cheaper or easier to use a low-spec single EC2 instance.
The Free Tier EC2 instance is almost same like the lowest cost Lightsail
instance.
And neither one will be suitable to run an entire OpenMeetings Server
(including Kurento).
It may be also an alternative to use an OpenMeetings Docker image compiled
from:
https://github.com/openmeetings/openmeetings-docker
And then spin that up in AWS.
But again, I'm not sure you are saving much in between all those options.
512MB memory won't be enough.
As well as Laightsail won't provide you with the Linux command line tools
you will need for OpenMeetings.
So you won't be able to use the full functionality of OpenMeetings on such
small spec'ed instances.

Seb

Sry Tom,
but I assume you want to install OpenMeetings into one of the containers
that you provision via AWS Lightsail ?
