Unisys’ Mark Forman: Hybrid, 4-Tier Architecture Facilitates Government Workforce Mobility

Mark Forman, global public sector head at Unisys, has said the adoption of a four-tier architecture could help government agencies facilitate mobility among their staff and change the way they deliver services to citizens.

Forman wrote in a Government Technology article published April 15 that such architecture employs a hybrid model of analog and digital systems.

He said the architecture works to leverage virtualization and cloud platforms as well as consolidate legacy systems and databases into “interoperable modules.”

He also cited the end-user interface, orchestration layer, business services and data tier as the four components of the four-tier architecture.

Forman noted that the architecture’s data tier approach works to generate insights through combination of data from different silos.

“We have known for more than a decade that combining data across silos and integrating business processes is not only a good way to reduce costs, but also has become necessary for government to perform critical operations,” he added.
