Web Server Memory Allocation

Based on your web server's physical RAM specification, allocate as much memory as possible to your web server.

For example, if the web server has 16 GB RAM, allocate at least 50 percent of it. That is, 8 GB. Higher memory allocation ensures better application function. The following table illustrates memory allocation:

Physical RAM	Allocation to Web Server
16 GB	8-12 GB
32 GB	16-28 GB
64 GB	48 GB

Enterprise Deployment Configuration

In case of enterprise deployment, for the best performance, it is recommended to allot at least 0.5 GB space per user on the application server. For example, if 30 users log on simultaneously, the application server must have at least 15 GB of RAM allocated to it.

Note: The above RAM allocation does not indicate the RAM of the server machine. It indicates the physical RAM allocation to the application server.

Database Server Specifications

The following table lists database server specifications:

Prerequisite	Specification
Server Type	Dedicated standalone server
Processor	64-bit, minimum 4-8 cores
RAM	16-32 GB
Hard Disk Drive	250-500 GB
