Frequently Asked Questions

What is Mainframe as a Service (MFaaS)?

Mainframe as a Service (MFaaS) is a fully managed service that delivers mainframe computing capabilities via the cloud or hybrid infrastructure. Instead of owning and maintaining expensive on-premise mainframes, clients can access secure, scalable, and high-performance mainframe resources on a subscription basis.

What types of workloads can run on your MFaaS platform?

We support a wide range of critical workloads, including:

  • Batch and transactional processing
  • COBOL, PL/I, and Assembler applications
  • CICS, IMS, and DB2 environments
  • z/OS, z/VM, VSE, and other IBM mainframe operating systems
  • Third-party tools and legacy applications

Whether you’re in finance, healthcare, government, or retail, we can handle your enterprise-class workloads.

How secure is your MFaaS solution?

Security is our top priority. Our MFaaS environments are hosted in SOC 2 Type II, ISO 27001, and/or FedRAMP-compliant data centers. We implement:

  • 24/7 monitoring and incident response
  • Role-based access controls (RBAC)
  • Encryption at rest and in transit
  • Multi-factor authentication (MFA)
  • Data backup and disaster recovery protocols

We also support compliance with HIPAA, PCI-DSS, GDPR, and other regulatory frameworks.

What are the benefits of moving to MFaaS?
  • Cost Optimization – Avoid capital expenditures (CapEx) and only pay for what you use
  • Scalability – Rapidly scale resources up or down as your business needs change
  • Reduced Risk – Leverage our redundancy, uptime SLAs, and disaster recovery plans
  • Operational Efficiency – Free your internal teams to focus on innovation, not infrastructure
  • Access to Expertise – Get direct access to senior mainframe engineers and modernization architects
Can you help us migrate from our current on-premise mainframe?

Absolutely. We provide end-to-end migration services including:

  • Discovery and assessment of your existing environment
  • Migration planning and risk mitigation
  • Data transfer and application validation
  • Cutover planning and post-migration support

We’ve completed dozens of successful migrations with minimal disruption.

How is MFaaS priced?

Our pricing is transparent and consumption-based. It typically includes:

  • Infrastructure usage (CPU, memory, storage, network)
  • Software licensing and support
  • Managed services (monitoring, patching, backups, etc.)
  • Optional services (disaster recovery, modernization, etc.)

We tailor packages to each client’s specific needs to maximize value and efficiency.

Do you offer support for legacy applications and modernization initiatives?

Yes. We specialize in maintaining legacy systems while enabling a path toward modernization. Services include:

  • Application refactoring or rehosting
  • Interface/API development
  • Integration with cloud-native services
  • Hybrid cloud enablement
Where is your infrastructure located?

We operate multiple secure, geographically redundant data centers across North America, ensuring business continuity, high availability, and compliance with data residency requirements. On-premise and hybrid hosting models are also available.

Who are your typical clients?

Our clients include mid-sized to large enterprises, government agencies, and service providers in:

  • Financial Services and Insurance
  • Healthcare
  • State and Local Government
  • Defense
  • Education
  • Logistics & Manufacturing

They rely on us for mission-critical uptime, operational excellence, and deep mainframe expertise.
