Mainframe, Legacy & Modernization
Mainframe, Legacy & Modernization
Workload and MIPS optimisation, legacy modernisation and lower total cost of operation in critical environments.
We modernise and optimise complex technology environments to cut costs, improve efficiency and get enterprise operations ready for what comes next.
We combine specialised engineering, automation and artificial intelligence to find optimisation opportunities, remove waste and speed up the evolution of critical systems — without compromising availability and stability.
“My mainframe operation is expensive. How do I cut that cost without putting system availability at risk?”
The question we hear from CIOs and infrastructure leaders
MIPS is not only a technical indicator: it is a meaningful line in the IT budget. We find and execute opportunities to reduce consumption, optimise workloads and remove unnecessary processing — measuring before and after every intervention.

From Legacy Complexity to Modern Enterprise Architecture
- Legacy EnvironmentApplications, routines and integrations piled up over decades, with cost and dependencies barely visible.
- Assessment & Workload AnalysisMapping of consumption, peaks, processing windows and dependencies between systems.
- MIPS & Performance OptimizationTuning routines, queries, batch and capacity to cut consumption without changing business behaviour.
- Application ModernizationProgressive evolution of the components that carry the most risk or the most cost, in controlled waves.
- Modern Architecture & IntegrationLegacy and modern architecture coexisting, with APIs that keep the operation running.
- Continuous OptimizationPermanent measurement: the gain holds because the environment stays under observation.
Modernising does not mean replacing everything. You can optimise, evolve and modernise progressively while preserving operational continuity.
Efficiency and capacity
Before buying more capacity,
look at what runs for nothing.
Cutting waste and optimising critical routines to expand the useful capacity of the operation — with no new infrastructure spend.
Transaction growth does not have to be matched, proportionally, by more processing and bigger contracts. Before expanding capacity, it is worth finding what the environment runs without need and where critical routines consume resources in excess.
The ≈15,000 processes are the aggregate result of several initiatives, not of a single project. The percentages come from the Legacy Systems Efficiency case in the Bitwise portfolio: they are historical results from that environment, with no guarantee of repetition, and they do not refer to the process clean-up. Every new scope is defined in a diagnostic.
When this conversation makes sense
- The batch window is close to its limit and delays the online opening
- There are old processes with no clear owner and doubt about what can be switched off
- The business needs to grow and the team is under pressure to expand capacity or contracts
- Recurring failures eat up the support team
From analysis to production
A routine with no recent execution may still be needed for year-end closing or contingency. That is why the clean-up is approved by the owners and always allows rollback.
How we work
From strategy to production.
From complexity to results.
Five stages that exist to get software into production — not to produce documentation.
- DiscoverWe understand the business, the architecture and the real operational challenges.
- StrategizeWe identify opportunities and set priorities by value and risk.
- EngineerWe design and build the solutions with real engineering.
- IntegrateWe connect the solutions to the company’s actual environment.
- EvolveWe measure, optimise and keep improving what runs in production.
Other practices
Bitwise does not solve just one problem.
