Enjoy the strength and computing power of the mainframe — and let Ensono worry about everything else.
Mainframe-as-a-Service is a monthly subscription model that solves the challenges of your aging mainframe while providing the scalability and flexibility to support your growth. This allows you to align your mainframe capacity with your unique business requirements, while reducing costs and enjoy the latest hardware and support with even greater security.
MFaaS gives you the processing might and speed of your traditional mainframe, without the expensive overhead and maintenance headaches.
Scale
With MFaaS, you can scale capacity up or down according to your changing requirements, with no hidden fees or surprises. Ensono Flex® is built into all contracts, allowing you to shift workloads across platforms with no penalty.
Predictable costs
MFaaS contracts charge a fixed monthly cost to operate and maintain. This changes your mainframe cost from a capital budget expense (CapEx) to an operating expense (OpEx), freeing budget and staff to support other urgent initiatives.
Maintenance and upgrades
You only pay for compute and storage consumed, not for any maintenance and upgrades to IT infrastructure. And, you have access to 24/7/365 continuous support.
Continuity
You enjoy improved business continuity and reduced downtime in the event of a mainframe failure or disaster with an MFaaS solution.
Security
You’ll gain greater control with a higher level of security transparency.
Do more with less. Mainframe-as-a-Service can provide immediate savings of 20% or more.

Aging infrastructure
While most organizations run their mission-critical applications on the mainframe, some have been in use for more than 50 years. Outdated hardware leaves you vulnerable to security risks, costly maintenance and unexpected downtime.

Skills gap
According to Forrester, organizations have lost 23% of mainframe workers in the last five years, and 63% of those positions remain unfilled. This leaves your mainframe dangerously isolated and unprotected without internal expertise to help.

High maintenance costs
Infrastructure and licensing expenses for mainframe rise each year as technology changes and systems get older. Supporting aging systems ties up capital that could be used for innovation and differentiation initiatives.

Risk
There are the hidden risks when a vendor retires software, frameworks and applications that the mainframe use. You risk using unsupported hardware or finding an expensive replacement solution quickly.
