How to decide how many instances of Cometd nodes reqd in a cluster

[Vedachalam Muralidharan]

Hi 

In our organisation we are planning to use Cometd to replace Skype as messaging service. So I wish to understand how to decide how many nodes need to be setup for 5000 users with messages & calls will be approximately 1 million / day. 

Help me to understand more about the architecture for cometd setup.

Thanks

Murali

One node should be enough (unless it's really, really, really small).

1M messages/day is just 10-15 messages/s, which is practically no load
for CometD (depends on the user logic, but typically if it is just
text chatting 15 messages/s is a very light load).

5k users is also a small number, which yields that on average a user
will send about 10 messages/hour, something that could be easily
handled by just one NIO selector on the server.

We have a customer with 1 (large) server running 150k users and 50k
messages/s, just to give you a reference.

Have you read the documentation at: https://docs.cometd.org/current/reference/?

to deliver bug-free software with optimal performance and reliability,
