MediationZone Image Added centralizes the control logic and distributes execution, and thus addresses the two main problem areas related to vertical and horizontal scaling architectures:

• Vertical scaling can lead to CPU contention where the scalability of a centralized architecture is limited to the number of plug-in processors supported by the hardware. MediationZone Image Added offers virtually unlimited scalability by its support for any number of collaborating networked servers.

• Horizontal scaling can lead to inconsistent maintenance of a distributed architecture when code and data potentially reside on a large number of servers. MediationZone Image Added supports automatic, on-demand distribution of code and configuration to servers configured to be part of the installation, thus reducing operation and maintenance efforts and ensuring a consistent configuration store.

Scale-out architecture

Logically, the platform Image Added platform is layered into three different zones:

• Access Zone is the layer where users access the system through a graphical interface or command line interface to perform operations and maintenance tasks. 
• Control Zone hosts configurations and provides storage and a range of services that are essential to the systemthe Image Added system.
• Execution Zone is a scale-out layer that provides processing capacity in the system. This layer contains one or several Execution Contexts and Service Contexts, which are distributed over any number of servers.
  • Execution Contexts are responsible for executing and supervising workflows. 
  • Service Contexts host services that workflows running in Execution Contexts can share.
