Technical Architecture for ACMS

The diagram below gives an overview of the technical infrastructure for LIVE ACMS systems:


Live ACMS Platform

Live ACMS Platforms are deployed as per the diagram above. Points to note:

  • The main ACMS system is a Java/JavaScript implementation supported by an ISAM database
  • Data is reflected to a MySQL database to support the production of reports and dashboards by the Database Server. This ensures;
    1. the production of reports for some users does not impact other users of ACMS.
    2. there is a relational model, which makes the development of custom reports simple using JasperReports and JasperServer.
    3. there are two Database servers and MySQL databases operating on a load share basis, providing resilience in the case of equipment/environmental failures.
  • For resilience, data from the ISAM database is reflected to a second ISAM database, which, along with a second copy of the Java/JavaScript, provides a hot standby for the live platform, in case of equipment/environmental failures.
  • At the Database Server level there is also a resilient platform that operates in a load-share mode with the primary. It can also take over completely in the case of platform issues.
  • All of the above is provided in our primary location. However (not shown on the diagram), all data is reflected to a secondary site and then to a third location that acts as a data store for backups. This is to facilitate disaster recovery.


AssessBook and AssessTube

AssessBook and AssessTube are deployed using the same resilient architecture as ACMS, except there is just a single pair of virtual machines for each. There is no ISAM database - these products have SQL databases to begin with. So, there is no need for reflection to an external SQL database.
