Mainframe-as-a-Service FAQ
-
What is Mainframe-as-a-Service (MFaaS)?
A managed, subscription model for IBM Z that provides hosted capacity, operations, security, and resiliency without the overhead of owning hardware or staffing every specialty.
-
What is typically included in FNTS MFaaS?
- IBM Z infrastructure hosting (prod/non-prod), capacity and performance management
- z/OS systems programming, maintenance, health checks, and job scheduling
- Security hardening, access controls, logging, and compliance reporting
- Backup, DR design, testing cadence, and runbook documentation
- Named customer success lead and access to mainframe SMEs
-
How is MFaaS different from outsourcing?
MFaaS is a service-level–driven operating model with clear RACI and SLAs; you retain strategic control while FNTS operates the platform end-to-end.
-
Which operating systems are supported?
z/OS and Linux on IBM Z (LinuxONE). IBM i and AIX are supported under FNTS Cloud for IBM Power, not MFaaS.
-
Can we modernize without rewriting apps?
Yes—FNTS prioritizes on-platform modernization and hybrid integration so you can expose data and services to cloud applications without disrupting core systems.
-
How do DR and backups work?
We implement layered recovery (immutable backups, offsite retention) and test regularly to verify RTO/RPO targets and compliance requirements.
Security, Compliance & Resiliency—Built In
Protect mission-critical workloads with layered defenses and coordinated recovery:
- Cyber Resiliency: Continuous monitoring, anomaly detection, and incident workflows with Mainframe Cyber Resiliency
- Backup & Recovery: Policy-driven snapshots and retention with Backup Services
- DRaaS Options: RPO/RTO targets aligned to business impact analysis—see Disaster Recovery
- End-to-End Visibility: Real-time threat intelligence and SIEM correlation via AMI Security
This layered approach delivers platform stability, workload integrity, and audit-ready evidence across regulated industries.
