Software as a Service is the most comprehensive service provided by Comarch Data Center, within which the following elements are provided:

  • administration of applications
  • a single point of contact for the customer and one SLA for all solutions
  • optional help-desk for end-users

Comarch is responsible for a comprehensive solution, so that a customer does not have to worry about the blurring of responsibilities between the provider of hardware, operating platform, applications, links or the teams responsible for the individual elements.



Within the PaaS (Platform as a Service) model, Comarch delivers a full system and hardware platform to support customer applications including:


  • providing the equipment, together with its co-location
  • providing all necessary third-party licenses
  • administration and management of the operational layer (e.g. operating system, database)
  • management of network layer and security
  • providing telecommunications links
  • 24x7 monitoring
  • one level SLAs for the entire system

Comarch also provides disaster recovery services in the event of failure, access to the system for end users and a full suite of administrative services and maintenance. Thanks to the shared environment, it is possible to use a more advanced IT infrastructure even for small systems. This eliminates the high initial costs for the project.
