since we have more applications coming up, we need to upgrade infrastructure. However, we don't want to jump a big step once. We need to upgrade, get better performance, while still save cost.
The current status is we have one server, all applications and databases are running on this server. We think about having 4 servers, 1 of them works as database server. The rest work as application server and implement load balance. But this plan seem too big for us at the moment.
At the end, we reach an agreement that we just get 1 more server. So we have two servers, 1 for databases, the other 1 for applications.
We will see how this works at the moment. If our business keeps growing, we definitely need to upgrade our hardware platform later.
