ModPaaS, developed by Modern Systems is a purpose-built, customisable Cloud solution that enables highly collaborative participation throughout a legacy application modernisation project.

You can analyse mainframe legacy code, understand the complexities and dependencies of interrelationships and mine business rules. It also gives you access to our modernisation solutions ‘as a service’ in a secure Cloud-based environment, with assistance from our modernisation specialists, or in a fully managed approach.

Understanding key issues


Controlling project cost

The knowledge gained from using ModPaaS reduces the scope of existing applications and refines the modernisation disposition strategy. Right-sizing these projects reduces costs too.

Unmaintainable code lines

Over time, code can become complicated. We can streamline the code on three levels – source code file, paragraph / section and line of code – simplifying the maintenance of applications.

Lack of legacy system visibility

Full visibility, including business rules, reports, documentation and application categorisation, puts you in control of your IT while ensuring it supports your organisation’s initiatives.
