Pre-Requisites

This section explains the system requirements to run Alpana Server.

Software

Operating System

Windows OS (x64) :

• Windows Server : 2012 R2, 2016
• Windows : 10 (Version 1607+)
  

Database

Microsoft SQL Server is required.
Microsoft SQL Server Express is possible, but see limitations related to this edition of SQL (concurrency, database size, resource usage, etc).

During installation, you will need a login to SQL Server which has the permissions to create users and databases.

!We strongly recommend to install the Alpana Server Database on the same machine that the web application: the web app being constantly communicating with its repository, if the repository and the application are on different machines, it will affect the performance and the user experience.

Other software

!Pre-requisites order is very important.
If you modify any IIS setting after installing AspNet Core, then you will have to Repair AspNet Core : see Installation Troubleshooting.

!You must restart IIS after installing AspNet Core.
You must restart the computer after installing a new version of .NET Framework.

Pre-requisites must be installed in the following order :

1. Microsoft IIS : this must be installed and configured first. Please follow the configuration requirements in chapter IIS Configuration pre-requisite.
2. PowerShell must be active
3. .NET Framework 4.8 must be installed. Installers can be found here : https://dotnet.microsoft.com/download/dotnet-framework/net48 then download the “Runtime”. Alternately, an offline installer exists on the same page . Installing this component requires to restart the machine.
4. AspNet Core 2.2 must be installed. Installers can be found here : https://dotnet.microsoft.com/download/dotnet-core/2.2 : select version “Hosting Bundle”. Installing this component requires to restart IIS.
5. Restart IIS
6. IIS URL Rewrite must be installed. Installers can be found here : https://www.iis.net/downloads/microsoft/url-rewrite : this should be installed after IIS

Hardware Requirements

!Hardware requirements highly depend on usage.
Typically, SQL and IIS will take disk space, disk I/O, RAM and CPU depending on several factors like database usage, dashboards complexity and website traffic.
Please see with your website and database administrators to size your application appropriately.

Hardware Minimum

!Those are the bare minimum that will get you a running installation.
As soon as you will add content, add data, and increase traffic, you will need more.

• HDD : 1GB
• RAM : 3GB including OS
• CPU : any dual core CPU, x86 or x64 architecture

Hardware Recommended

To go beyond the minimal installation, you will need evaluate your requirements based on traffic, number of dashboards, number of tenants, other software and databases hosted on the same machine, etc…

Typically, it’s recommended to have at least :

• SSD for fast I/O, 50GB+ with free space always available (usual system administrator advice apply)
• RAM : 8GB for a small/medium site with few databases an no other big software installed
• good server CPU, like recent Xeon
  

This can be much more if your application serves many dashboards to many users on many tenants.
