Cloud Migration
Migrate to Google Cloud without pausing the business
Discovery-led migration into a secure landing zone: infrastructure, applications, databases and storage moved in planned waves, with modernization applied where it earns its place.
Business challenges
What usually brings teams to us
These are the recurring conditions we are asked to resolve. If several look familiar, an assessment is the efficient starting point.
Unmapped dependencies
Nobody can state with confidence what a given application talks to, so every cutover carries unquantified risk.
Ageing infrastructure
Hardware refresh or licence renewal deadlines are forcing a decision before a target architecture exists.
Lift-and-shift regret
An earlier migration moved virtual machines unchanged and reproduced the original operational burden in a new place.
Compliance uncertainty
Data residency, encryption and audit requirements are unclear enough that regulated workloads stay put.
Manual environments
Environments differ because they were built by hand, so testing a migration proves little about production.
Stalled programmes
The first wave shipped, momentum faded, and the estate now spans two platforms with double the operational cost.
Our approach
Landing zone first, then planned waves
We establish a secure, automated landing zone before workloads arrive, then migrate in dependency-aware waves with explicit validation criteria at every cutover.
- Automated discovery of inventory, dependencies and utilization to replace institutional guesswork.
- A landing zone defined in Terraform: projects, networking, identity, logging, guardrails and cost boundaries.
- A per-application disposition — rehost, replatform, refactor or retire — argued on cost and risk, not fashion.
- Wave planning that groups applications by dependency, so cutovers are self-contained and reversible.
- Database and storage migration with tested replication, cutover rehearsal and rollback criteria.
- Post-migration optimization: right-sizing, commitment strategy and reliability review once real load lands.
Core capabilities
What we deliver
- Infrastructure migration
- Compute, network and storage moved into a governed landing zone.
- Application migration
- Dependency-aware wave planning, cutover rehearsal and validation.
- Application modernization
- Selective refactoring where it reduces operational cost meaningfully.
- VMware migration
- Migration paths for existing virtualized estates into Google Cloud.
- Kubernetes modernization
- Cluster architecture, workload identity, autoscaling and release strategy.
- GKE
- Production cluster design, node pool strategy and multi-environment promotion.
- Cloud Run
- Serverless containers for services that do not warrant a cluster.
- Compute Engine
- Right-sized instances, images and managed instance groups.
- Storage modernization
- Object, block and file storage mapped to access patterns and retention.
- Database migration
- Replication, schema conversion, rehearsal and cutover for relational estates.
- Landing zones
- Project hierarchy, networking, identity, policy and logging baseline.
- Infrastructure as Code
- Terraform modules, environment promotion and drift detection.
- Security and compliance
- Least-privilege IAM, encryption, network controls and audit logging.

Delivery
Migration lifecycle
Every wave follows the same sequence, so the second migration is more predictable than the first.
01
Discover
Inventory, dependencies, utilization and constraints captured from the running estate.
02
Assess
Per-application disposition, risk, effort and sequencing agreed with owners.
03
Design
Target architecture, landing zone changes and cutover plan documented.
04
Migrate
Wave executed against the plan, with rehearsal before any production cutover.
05
Validate
Functional, performance and security validation against pre-agreed criteria.
06
Optimize
Right-sizing, reliability review and cost commitments once real load is observed.
Business outcomes
What changes as a result
Predictable waves
Cutovers become routine because scope, validation and rollback are defined up front.
Reduced complexity
Managed services replace undifferentiated infrastructure the team was maintaining.
Reproducible environments
Terraform-defined environments that can be rebuilt rather than repaired.
Security by default
Guardrails, least-privilege IAM and audit logging exist before workloads arrive.
Controlled run cost
Right-sizing and commitment strategy applied against observed usage.
A team that can operate it
Runbooks and enablement delivered with the migration, not after it.
FAQ
Common questions
Should we modernize during migration or after?
Selectively during. Modernizing everything mid-migration extends risk windows; modernizing nothing reproduces the original problem. We decide per application on cost and risk.
Can you work alongside our existing infrastructure team?
Yes, and that is the usual arrangement. We lead architecture and wave planning while your team retains operational ownership throughout.
How do you handle regulated workloads?
Residency, encryption, access and audit requirements are captured in the landing zone design and validated per wave. We do not assert compliance certifications on your behalf.
What if a previous migration already stalled?
We start with discovery of the current split estate, then sequence the remaining waves to collapse dual-running cost as early as possible.
