In 2006, Agos deployed IBM Z Systems as the central platform for its core business processes. The IBM Z Systems implementation delivers Application Hosting and Computing Services for transaction processing, lending workflows and operational control across the companys IT estate.
The IBM Z Systems environment hosts Agoss proprietary core applications enabling automated transaction processing and in-line transaction validation as part of day to day operations. Administrative, accounting and human resources functions run on SAP applications, while reporting and analytics are fed from a SAS data warehouse running on a Linux GRID infrastructure, with operational data replicated from the mainframe for business monitoring and control.
Agoss IT architecture is centralized at its Milan head office and uses an MPLS network supplied by British Telecom and VPN connections for remote access. Dealers enter customer loan files through the corporate website into systems that interface with the IBM Z Systems mainframe, and internet facing services are isolated in a DMZ behind a perimeter firewall. Critical systems and services are replicated across two data centers, a primary production site and a disaster recovery site, using synchronous PPRC storage replication, RAID protected storage and regular full backups to tape stored in an offsite vault more than 50 kilometers away.
Governance and compliance workflows are aligned with the rolling internal control framework described by Agos, where automated transaction processing on IBM Z Systems supports first level controls performed within business units, second level risk and permanent controls performed by independent units, and third level internal audit oversight reporting to the CEO and board. Compliance with Crédit Agricoles Fides policy is managed across Legal, Compliance and Financial Security functions, and the company has adopted an organizational and management model under Law Decree 231 2001.
Operational reliability is explicitly supported by the IBM Z Systems deployment and the companys Business Continuity Plan, which is updated annually. The mainframe centric architecture is described by Agos as providing high flexibility and independence for core applications, while the replicated data center strategy and backup procedures underpin the Application Hosting and Computing Services posture for business continuity and disaster recovery.
