Hi Mathews;

  PowerServer 2021 applications only require http & db client access which boils down to basically the use of TCP/IP. So you can put any of the pieces anywhere you want IP wise. For the best performance though, having all the pieces on the same network segment generally avoids excessive network latency (delay).  HTH

Have managed to put all pieces in one server and the performance is much better. For security purpose it is recommended to host each piece on their own servers.

Thank you

Hi Matthews,

Best practice from security and high-availability perspective is to have multiple servers for each layer.  So you would have multiple Web servers, multiple API servers, and multiple database servers. As Chris pointed out, all these servers should be within the same LAN.

Of course, such best practice may be overkill for your situation.  If you don't need high-availability then you can get away with a single server.  But from a security standpoint, it's generally a good idea to at least have the database server separate from the Web server.  

Again, just to clarify, none of what I said is requirement of PowerServer.  You asked what is "advisable" so I am just outlining some best practices I have seen.

Best regards,
