    Our Standard: Zero-Compromise Availability

    For organisations in banking, healthcare, and government, downtime is not just an inconvenience—it is an unacceptable risk. Nulink's Critical Infrastructure Services provide the 24/7 operational backbone required to run high-stakes environments. We manage the availability, security, and performance of your most vital assets, so your business operations never miss a beat.

    We manage infrastructure with a disciplined "failure is not an option" mindset, adhering to strict SLAs and regulatory frameworks (HKMA C-RAF, Hospital Authority standards).

    Managed IT Critical Infrastructure Services

    1. High-Availability (HA) & Disaster Recovery

    We design and operate infrastructure that survives disruptions.

    Active-Active Architectures

    Managing geographically redundant clusters that ensure seamless service continuity even if a primary data center fails.

    Business Continuity Planning (BCP)

    Rigorous, tested disaster recovery drills that go beyond paperwork. We simulate failures to prove recovery time objectives (RTOs) are met.

    Data Integrity Replication

    Synchronous data mirroring for financial transaction systems to ensure zero data loss (RPO=0) during outages.

    2. Banking & Regulated Cloud Operations

    We understand the specific constraints of regulated industries.

    Private & Hybrid Cloud Management

    Operating secure on-premises environments (Azure Stack, Private AI/GPU Clusters) for data that cannot leave your physical perimeter.

    Compliance-Ready Patching

    Managing vulnerability lifecycles with strict change control procedures that satisfy HKMA and ISO 27001 auditors.

    Legacy System Stewardship

    Expert management of core banking/backend systems (Mainframe, AS/400 connectivity, or legacy Windows/Linux stacks) that must co-exist with modern cloud layers.

    3. Healthcare & IoT Infrastructure

    Managing the physical-digital convergence in critical care environments.

    Clinical Infrastructure Support

    Monitoring and maintaining the backend systems supporting Electronic Health Records (EHR) and PACS imaging data.

    RTLS & IoT Management

    Operational support for Real-Time Location Systems (RTLS) and asset tracking networks in hospitals, ensuring 100% uptime for patient safety tracking.

    Edge Computing Security

    Securing distributed endpoints and gateways that process sensitive data at the edge (clinics, branches, or field offices).
