WebDev Connections Limit

I have a large medical practice management app in the UK built with WebDev. I run a Windows AWS server and a postgreSQL database. It runs extremely well. I have seen up to 300 concurrent connections on the server. The server has 32GB RAM and at peak is using about 60% memory and generally less than 30% CPU.

Does anyone have experience of large deployments like this in WebDev. I think my current growth will enable me to run for another year before I start hitting close to 90% memory at peak. I can then double the server RAM if needed. Is this a good idea? It's certainly a simple solution but I'm sure setting up a second server is a better idea.

I would welcome thoughts.

I think this was discussed a while back....and I mean way back...and the numbers discussed at the time were up to 1000 concurrent connections for WAS. Of course with advancements in server capability, low cost memory and superfast networks, that number could easily be beaten. And then there is the option of splitting the server and the database and if push comes to shove, using multiple servers with a load balancer.

I think you'll be fine
