Why migrate now: aligning business outcomes with the Google Cloud journey
When organizations tie technical changes to concrete business targets, every project becomes a driver of growth and resilience. We frame moves as outcome led, so finance, product, and operations all see measurable value.
We connect decisions to business value: lower costs through granular pricing and managed services, improved performance from elastic infrastructure, and faster releases that support revenue.
- Reduce undifferentiated work: no more managing facilities, hardware, or hypervisors so teams focus on workloads and customers.
- Gain agility by using scalability on demand for rapid experiments, faster deployments, and resilient services.
- Prioritize migrations by assessing source environments and classifying workloads as legacy or cloud‑optimized to limit risk and effort.
| Business Goal | Expected Benefit | Key Metric |
|---|---|---|
| Cost control | Lower TCO via managed services | Monthly cost, cost avoidance |
| Performance | Predictable latency and throughput | Response time, uptime |
| Agility | Faster releases and scaling | Change lead time, deploy frequency |
Build a strong foundation: assessment, planning, and cloud readiness
To build a dependable foundation, we first discover systems, measure readiness, and convert findings into an actionable plan. This early work removes guesswork and focuses teams on the highest‑value workloads.
Leverage Migration Center for discovery and guidance
Migration Center provides built‑in discovery, assessment, and cost estimation so we can inventory apps, servers, databases, interdependencies, and data flows. We quantify TCO and readiness, producing clear inputs for planning and prioritization.
Apply the Adoption Framework: Learn, Lead, Scale, Secure
We evaluate organizational maturity across Learn, Lead, Scale, and Secure to expose learning gaps and governance needs. That evaluation aligns people, training, and timelines with technical goals, turning assessment into capability building.
Plan organization, IAM, networking, and landing zones
The Cloud Foundation Toolkit offers IaC templates to codify organization structure, IAM roles, VPC design, and landing zones as repeatable infrastructure. We enforce security baselines early—least privilege, encryption, and centralized logging—so compliance is built in.
Estimate costs and validate sequencing
We model costs with the pricing calculator and stress‑test scenarios across regions and instance families, then engage RaMP for a detailed IT landscape assessment and sequencing advice. That combination helps us prioritize low‑risk pilots and plan rollback windows.
| Activity | Purpose | Outcome |
|---|---|---|
| Discovery & Assessment | Inventory apps, data flows, dependencies | Readiness score, prioritized workloads |
| Foundation IaC | Deploy org, IAM, VPC, landing zones | Repeatable, secure infrastructure |
| Cost Modeling | Estimate region and instance costs | Validated TCO, staged plan |
| Governance & Training | Align teams, fill learning gaps | Faster, lower‑risk migrations |
Google Cloud Platform migration: selecting the right approach for each workload
We match each workload to a migration type by weighing time‑to‑value against future capabilities and operational risk. Choosing the right path helps teams move faster while preserving options for later optimization.
Rehost, Replatform, Refactor: when lift, optimize, or improve makes sense
Rehost is the fastest route for stable apps that need minimal change. It reduces cutover time and supports staged validation.
Replatform gains near-term benefits like managed databases, autoscaling, or container hosting without a full rewrite.
Refactor updates code and architecture to use managed services, messaging, and identity for scalability and resilience.
Re‑architect, Rebuild, Repurchase: modernize, replace, or move to SaaS
Re‑architect decomposes monoliths into services when agility and reliability justify the effort and testing.
Rebuild is for apps that are costly or impossible to modernize; a clean slate aligns design to new capabilities.
Repurchase replaces commodity functions with SaaS, freeing teams to focus on core differentiation.
Map legacy vs. cloud‑optimized workloads to migration types
We map legacy and modern apps to types, sequence work into pilots, and define acceptance criteria—SLA, cost, and rollback gates—before deployment.
- Balance quick wins with long‑term flexibility.
- Sequence multi‑step moves: rehost, then iterate toward refactor or re‑architect.
- Use testing and staged deployment to validate assumptions and limit risk.
| Migration Type | When to Use | Key Outcome |
|---|---|---|
| Rehost | Stable apps needing fast lift | Quick cutover, minimal code change |
| Replatform | Apps benefiting from managed services | Improved resilience, lower ops effort |
| Refactor | Apps needing scalability and HA | Cloud capabilities unlocked, code updates |
| Re‑architect / Rebuild | Monoliths or unsupported tech stacks | Modern design, long‑term agility |
| Repurchase | Commodity functionality | Faster time to value, less maintenance |
Execute with confidence: tools and services for apps, VMs, containers, and data
We unlock steady execution by pairing automation with staged validation, so each workload moves only after pre‑migration tests and rollback gates succeed.
Migrate to Virtual Machines
Migrate to Virtual Machines automates Compute Engine adaptations, runs pre‑migration testing, and supports fast stateful rollback to protect critical workloads.
Migrate to Containers and GKE
Migrate to Containers extracts apps from servers or vms and converts workloads into containers for GKE without changing source code, improving portability and manageability.
Google Cloud VMware Engine
This fully managed VMware stack preserves existing tooling—vSphere, vCenter, vSAN, NSX‑T, HCX—so enterprise portfolios move faster and see lower TCO while keeping infrastructure familiar.
Database Migration Service and BigQuery Migration Service
We use Database Migration Service for low‑downtime moves to managed databases with continuous replication. BigQuery Migration Service accelerates warehouse moves and speeds analytics on elastic storage and compute.
Transfer Appliance and Storage Transfer Service
For large data sets we choose Transfer Appliance when bandwidth is constrained, or Storage Transfer Service to automate ongoing transfers from on‑prem or other providers.
- Run pilot waves, then expand after testing confirms performance and scalability.
- Engineer deployment pipelines with dry runs, validation gates, and rightsizing for cost and performance.
- Standardize observability and align services to compliance and regional requirements.
Security, compliance, and governance baked in from day zero
We treat governance as infrastructure: codified, testable, and applied consistently across accounts and projects. Early design reduces surprises and keeps cutovers aligned with business commitments.
Shared responsibility and hardened workloads
We operationalize shared responsibility by hardening workloads—patching, baseline configs, and vulnerability management—while Google secures the physical facilities and core platform.
Zero‑trust identity, encryption, and policy controls
We design zero‑trust IAM with least‑privilege roles, short‑lived credentials, and separation of duties across projects. Encryption in transit and at rest is enforced, with CMEK and secrets management where needed.
Audit, SLAs, and regulatory validation
We codify guardrails as code using the Cloud Foundation Toolkit and policy libraries, and we integrate centralized logging, SIEM, and audits to prove compliance.
- Protect data during transfer with secure services and validated handling.
- Segment networks and apply identity‑centric access for distributed teams.
- Embed security testing and sign‑offs into change processes before any workload goes live.
Optimize after landing: performance, reliability, and cost management
Post‑cutover work converts a successful move into ongoing value by tuning resources, validating behavior, and enforcing spend controls.
We start with rightsizing. For vms, containers, and databases we adjust CPU, memory, and disk profiles, and set autoscaling rules to match real demand.
Performance testing follows. We run benchmarks, synthetic checks, and query profiling for Cloud SQL and BigQuery to confirm throughput and latency targets.
Operational controls and AI insights
Active Assist provides AI/ML recommendations that flag idle resources, unattached disks, and over‑provisioned services. We convert those alerts into backlog items for teams.
- Apply labels and tagging to track cost by app, team, and environment.
- Set budgets, alerts, and quotas to stop runaway spend while allowing scalability for peak periods.
- Use VM Manager for scheduled patching and configuration compliance across vm fleets.
Continuous optimization loop
We standardize performance testing and synthetic monitoring so SLAs stay intact and regressions surface early.
Telemetry and machine insights inform iterative tuning of pipelines and analytics, improving real‑time decisions and lowering operational cost.
| Focus Area | Action | Expected Outcome |
|---|---|---|
| Rightsizing | Tune CPU, memory, disk, autoscaling | Balanced performance and lower cost |
| AI Insights | Active Assist identifies optimization candidates | Reduced waste, prioritized backlog |
| Governance | Labels, budgets, alerts, quotas | Granular cost ownership and spend control |
| Reliability | VM Manager patching, synthetic tests | Improved uptime and compliance |
We share optimization playbooksso teams reuse proven steps and evolve practices as workloads and services change. This keeps performance high and costs predictable over time.
