1. Select Server Machines
2. Install Third-party Software
3. Install EASA
4. SSL configuration
5. Choose an Authentication Method
6. Add a User Account
7. Configure Email
8. File Management and Backups

The number of individual machines in an EASA system is determined by:

• Type of software application
• Number of simultaneous Users

EASA System Architecture outlines various use cases.

EASA Hardware Requirements provides a detailed specification for each machine role.

• From these pages determine the aggregate number of EASA machines:
  • One EASA Server or EASA/EASAP Server
  • Zero, one or more Compute Server(s)
  • Zero, one or more Excel Server(s) or Excel/EASAP Server(s)
  • Zero, one or more Database Server(s)
• Number of CPU cores per machine
  • Typically 4 cores for an EASA Server
  • Typically 8 cores for an Excel Server or Excel/EASAP Server
  • Compute Server or Database Server CPU requirements depend exclusively on the the third party software
• Amount of RAM per machine
  • Typically 4GB for an EASA Server
  • At least 8GB for an Excel Server or Excel/EASAP Server for ~16 simultaneous Excel processes
  • Compute Server or Database Server RAM requirements depend exclusively on the third party software

System Software Requirements outlines which Windows or linux versions are supported under EASA, install one of these operating systems.

EASA is written in Java which gives a high degree of cross-platform portability.

Many customers install EASA on a Microsoft Windows system simply because their IT department already supports it.

EASA should be installed after any necessary third-party software is installed.

This includes:

• Microsoft Excel on an Excel Server
• a database product on a Database Server
• required software for any other kind of Compute Server
  • (eg. MATLAB, an engineering simulation code, a Windows batch application, etc…)

After step 1. and step 2. → Install the EASA System

By default an EASA Server will communicate with other machines and with a browser using HTTP.

To encrypt network traffic follow the steps in:

• EASA Security: HTTPS and SSL

By default an EASA Server is accessed from a browser and requires a User, Author or Administrator manually login.

The two default login:password pairs are below:

• author:author
• admin:admin

Two additional authentication technologies are available:

• LDAP see → Configure LDAP Authentication
• SAML see → Configure SAML Authentication

To add a User, add a User Group or add an EASAP Category see:

• Access Control in EASA

Follow these instructions to:

• Enable Email in EASA

There are a number of software tools as well as hardware infrastructure that preserve the data integrity of an EASA installation.

<SERVERDATA> contains all customer-related data; this data cannot be recovered if lost

<EASAROOT> is the actual EASA software and may be regenerated by a re-installation.
