nvestment Protection for Legacy Software:

Legacy App Support & Takeover of Existing Applications

A functional system—whether an initial MVP or a complex application evolved over years—represents immense value: it encapsulates the collective knowledge, investments, and established processes of your company. We take over your application, reduce technical debt, and ensure high-performance continuity on a sovereign cloud platform.

Evolution Instead of a Radical New Start

In software development, the call for a complete rebuild often arises quickly when dealing with historically grown code. However, such a "rewrite from scratch" is extremely expensive and frequently destroys vital implicit insights that have flowed into the existing logic over years.

Our approach is different: we respect your software's history. Instead of tearing down established structures, we stabilize the existing foundation and make it future-proof. This protects your initial investments and enables continued operation.

Stagnation: When Development Comes to a Halt

Many clients come to us when an application still delivers business value, but the partnership with the original agency or development team has ended. Even if the system runs smoothly today, an invisible decay begins the moment development stops. Frameworks become obsolete, security vulnerabilities remain unpatched, and technical debt accumulates. This is precisely where our Managed Service steps in: we don't just provide hosting; we bring an experienced Development and Operations team to the table.

We dive into the code and assume full technical responsibility:

  • Active Reduction of Technical Debt: We update dependencies, close security gaps, and restore architectural maintainability.
  • Bug Fixing & Refactoring: We clean up the code and eliminate existing bugs.
  • Predictable Security: With a flat-rate maintenance contract, we secure continuity in a budget-friendly manner—with no hidden costs for necessary updates.

Code Optimization Instead of a Resource Arms Race: Escaping the Hyperscaler Trap

When taking over existing applications, we often find that companies are stuck in oversized and expensive dependencies with major hyperscalers. The common fix for performance issues there is usually: book more hardware. If the application reacts slowly, server capacity is simply cranked up. While this masks the problem in the short term, it drives costs up relentlessly.

We rely on deep technical understanding rather than blanket hardware upgrades. Countless migrations show that a more conscious use of resources holds enormous savings potential. It is often far more efficient to optimize code—for example, by shortening database query runtimes—than to simply provide more computing power.

On our own Flying Circus Cloud platform, your application doesn't just gain efficiency and reduced running costs; you also regain your digital sovereignty!


No risk for your digital strategy!

Interventions in the digital value chain – whether changing platforms or service providers – require absolute certainty. Our proof of concept (PoC) serves as risk-free due diligence.

Even before signing the contract, we validate success together: we make an advance investment by migrating your application to our platform for testing. This allows us to demonstrate our technical expertise, while you can check the business value directly on your real project.

Your advantage is full transparency: a direct comparison with the current situation shows in black and white what we can achieve. Without demonstrable added value for your application, you do not enter into a long-term commitment. This allows us to eliminate investment risks almost completely before you have to make a final decision.
