When business-critical software needs to change

We take ownership of existing platforms that need modernising, scaling or integrating, from architecture and implementation through to deployment and ongoing support.

  • Legacy .NET modernisation

    Business-critical systems stuck on .NET Framework, WebForms or WCF. We upgrade them to modern .NET step by step, without a risky big-bang rewrite.

  • Cloud & platform modernisation

    Monoliths on ageing servers or hand-built VMs. We re-platform them onto well-architected Azure or AWS infrastructure that is containerised, automated and observable.

  • APIs & system integration

    CRMs, payment providers, SaaS platforms and legacy applications that don't talk to each other. We connect them with secure, well-documented APIs and event-driven integration.

  • Application support & continuous improvement

    Platforms that must stay secure, patched and improving after go-live. We monitor, maintain and enhance them with agreed engineering capacity every month.

Three ways to work with Idabyte

Start with a fixed-fee Platform Health Check, move into delivery when you're ready, and keep your platform healthy with Application Care.

  1. Step 2: deliver

    Modernisation & Integration Delivery

    Fixed scope, milestone payments

    Projects that implement your roadmap, delivered by an Idabyte team against agreed milestones and acceptance criteria.

    • Legacy .NET to modern .NET
    • Azure and AWS cloud migration
    • API and system integration
    • CI/CD, containers and deployment automation
    Discuss a project
  2. Step 3: run

    Application Care

    Monthly plan, ongoing

    Ongoing engineering ownership after go-live, or for a platform you already run, under one monthly agreement.

    • Monitoring and performance tracking
    • Incident support
    • Security updates and dependency upgrades
    • Small enhancements
    • Monthly architecture review
    • Agreed engineering capacity
    Ask about Application Care

You agree the outcome. We own the delivery.
