Configuration steps

The CMS is based on Drupal 7.x. and is installed at /var/www/html. There is a custom theme created and installed at /var/www/html/sites/all/ecompass.

The theme contains the CSS of the Cockpit and the custom templates/code of the site. Custom templates:

• node--sales_optimiser.tpl.php
• node--price_monitor.tpl.php
• node--visitor_profiler.tpl.php
• node--product_characterisation.tpl.php
• node--price_monitor_configurator.tpl.php
• node--competitor_profiler.tpl.php
• node--dashboard.tpl.php

Configuration of REST endpoints at: /var/www/html/sites/all/ecompass/functions.php

Operation

Service startup procedure

• Apache (web server): service httpd stop| start | restart
• Mysql (mysql server): service mysqld stop| start | restart

Limitations of the service

How many concurrent E-Shops with how many concurrent products are possible without causing loss in quality/speed for the hardware described above?

There is no limitation for the number of concurrent users. All information is stored in different back-ends and is transferred on demand via http rest services to the ECC. The problem is that the user may experience delays when a large amount of data is requested.

If higher scaling was wanted, which of the hardware parameters would need to be increased?

Currently none of the hardware parameters is the bottleneck in the ECC performance. The bottleneck is the network.

What else would be adjusted for higher scalability?

A solution would be to store the data in a central database (or a clustered database) and use SQL queries instead of http REST services. All data from the various services of the distributed Ecompass platform should be saved in a central database (or a clustered database). This solution would significantly speed up the ECC.

Which further configuration would be necessary?
