MODERNISATION

Infrastructure Modernisation and Managed Migration

From legacy server rooms to hybrid cloud and from fragmented vendors to one managed service: network upgrade, facility and cloud build, migration, then 24/7 operations.

01Customer situation

The existing server room is ageing, the network architecture has not changed in years and operations are spread across several outsourcers. The business wants cloud adoption or a new facility, but there is no unified migration plan and nobody to take over operations afterwards.

Typical issues
  • Facility and network equipment out of support, failure rates rising, spares hard to source
  • Application dependencies undocumented; nobody dares to migrate
  • Several outsourcers each own a slice; no one coordinates changes
  • Cloud and on-premises resources are managed separately with inconsistent cost and security policy
  • No operations owner after migration; still dependent on per-incident OEM support

02Business risk

  1. Legacy equipment failure interrupts the business with no fast recovery
  2. Failed or late-rolled-back cutover causes extended downtime
  3. Inconsistent security policy between cloud and on-premises becomes an audit finding
  4. Operational knowledge sits with a few outsourced staff and leaves when they do

From customer-authorised cases; measurement basis under “Evidence”. Your results depend on the baseline assessed for your project.

03Target architecture

Assessment and design
Asset, dependency, cost and risk inventory; target architecture (on-premises / private / public cloud split), network and security architecture, migration wave plan.
Network upgrade
Campus / data-centre network, WAN and cloud interconnect, security perimeter; implemented and accepted to HLD / LLD.
Facility and cloud
Facility retrofit or build, server and storage integration, cloud landing zone and account governance; hardware procurement, staging and asset registration executed by GSS.
Migration and cutover
Applications migrated in waves; each wave has testing, cutover and rollback plans, executed outside business hours after customer review.
Managed operations
After migration, transition to active-active NOCs in Beijing and Shanghai for 24/7 monitoring, hardware maintenance, change management and monthly reporting; alarm noise reduction and root-cause analysis on the AIOps platform.

Wave-based migration method

  1. Assess: asset inventory, application dependency map, cost and risk matrix; output target architecture and wave plan.
  2. Network before systems: upgrade and accept the network and security perimeter first as a stable foundation for migration.
  3. Cut over by wave: each wave includes testing, cutover, rollback plan and review; low-risk applications first, core systems last.
  4. Operations takeover: monitoring and change management start at migration completion; steady-state operations begin once a baseline is established.

Our principles

  • One accountable party: from facility to cloud to operations, the customer deals with GSS alone; responsibility boundaries are written into the proposal and order.
  • Every change can be rolled back: no cutover runs without a reviewed rollback plan.
  • Knowledge stays with the customer: as-built documentation, configuration snapshots and runbooks belong to the customer, reducing dependence on any single vendor.

04GSS scope of responsibility

GSS owns
  • Assessment, target architecture and migration plan
  • Implementation and acceptance of network, facility and cloud environments
  • Hardware procurement, staging, delivery, installation and asset register
  • Cutover execution and rollback assurance
  • Post-migration 24/7 managed operations and reporting
Customer owns
  • Downtime windows, migration priorities and acceptance criteria
  • Application owners participate in testing and cutover sign-off
  • Cloud account ownership and billing entity
Ecosystem partners
  • OEMs provide hardware warranty and advanced technical support
  • Public cloud providers supply resources and vendor support

05Engagement model

Migration project
Assessment, design, implementation and cutover delivered once; accepted and invoiced by wave.
Migration plus managed operations
Transition to GSS managed operations after the project, monthly fee by device or site count; service tier per contract.
Operations takeover
No migration; GSS takes over 24/7 operations of the existing estate after a 4-week assessment and baseline.

06Evidence and measurement basis

  • Reference outcomes come from cases published with written customer consent (a multinational pharmaceutical company's China operation, an auto-parts manufacturer); measurement is 6–12 months before/after.
  • "Alarm volume ↓ 88%" compares alarm counts over equivalent periods and results from noise reduction and threshold governance; it does not represent a change in incident count.
  • "Major-incident identification 3h → 25min" compares mean time to identify for P1 incidents.
  • Implementation duration and downtime windows are agreed per project scope; the page makes no blanket commitment.

Auto-parts Manufacturer Multi-plant Smart Cloud and AI Inspection

Inter-plant MPLS was expensive and slow to scale, and ERP / MES moved to cloud with degraded experience; nightly data sync with German HQ took over six hours; manual visual inspection on the line missed defects and left no traceable quality data.

Multinational Pharma China AIOps and Compliant Data Centre Operations

China IT was managed remotely by global HQ with only six local staff covering GxP data rooms, a nationwide office network and cloud. Eleven monitoring tools generated 15,000 alerts a month with under 5% actionable, and major incidents took three hours to diagnose. Global HQ required English reporting and audit evidence from any local vendor.

Energy / SOE A central state-owned energy enterprise

Energy SOE Unified Wireless Access and AI Network Assurance

Each province had built its own wireless with different SSIDs, authentication and security policies, so staff could not roam across provinces and HQ could not audit device access. Remote-site network faults waited for a provincial engineer to travel, averaging over two days to fix.
